I am trying to build the mySQL Connector C++ from source in Visual Studio 2012 for the 64-bit architecture.
I understand that it depends on some boost header files and the C connector.
Running CMake produces a project file, but that project file doesn't compile because of a big list of very confusing errors which probably have to do something with the include files, and an even bigger list of warnings. The official site is of little help.
Could some one please list all the steps in successfully compiling the C++ Connector?
In order to build it you need to have the following:
You need to have installed either the MySQL server or the MySQL C Connector.
Have installed the Boost C++ libraries or have the source files for it. Please note that there is not need to build boost as you only need the header files.
Have CMake installed. When installing CMake it will ask you if you want it included in the PATH variable, you should select yes to make it easier later to use it.
Once you have all three available, open VS2012 x64 Native Tools Command Prompt and from the source root directory of the MySQL C++ Connector you need to issue the following:
set MYSQL_DIR=c:\PROGRA~1\MySQL\MYSQLC~1.1
cmake -G "Visual Studio 11 Win64" ^
-DBOOST_ROOT:STRING=C:\Users\user\DOWNLO~1\BOOST_~1\BOOST_~1 ^
-DMYSQL_LIB_DIR:STRING=c:\PROGRA~1\MySQL\MYSQLC~1.1\LIB
devenv.com MySQLCPPCONN.sln /build Release
The first command defines the MYSQL_DIR variable that points to the installation of the MySQL server or the MySQL C Connector.
The second command call cmake to prepare a VS project that will be 64bit. There seems to be a problem with the MYSQL_LIB_DIR variable and it does not get generated, so we need to define it manually. MYSQL_LIB_DIR has the value of MYSQL_DIR ending with a \LIB.
Third command is optional, it will build the project from command prompt without opening VS.
It is recommended that you use the DOS paths for the variables.
To do that, navigate to the directory you want to convert to DOS path and call for %I in (.) do echo %~sI. It will give you the converted path.
It's really tough task and I've spent lot of hours figuring this out.
There are two issues here:
C++ Connector and MySQL libraries they have provided have been generated with Visual Studio 2010. Hence we can not use them as it is under VS2012 (It gives version mismatch error)
They also have not specified exact compiler options under which they have compiled these libraries. If our compiler settings are different, we'll end up in lots and lots of (especially linker related) errors.
Considering these facts, the only way is to build ourselves these libraries. Building MySQL is quick but building connector is little complicated.
Here are steps I am sharing. In my case I wanted to link these libraries statically with my project so I built these libraries accordingly. You may want to make relevant changes wherever necessary as per your need.
Before continuing with these steps, please download and install CMake on your system.
Steps to build MySQL server:
Download MySQL source. Extract them. Go in extracted folder in command prompt.
Create BLD forder
Go in BLD folder through command prompt
Run
cmake .. -G "Visual Studio 11 2012 Win64"
It will create MySQL.sln
Open MySQL.sln in Visual Studio and build only 'mysqlclient' library (as only this would be needing by application)
This will build libraries in mysql-5.6.24\BLD\libmysql\< Configuration > folder which we link in our project.
Steps to build C++ connector:
Download mysql-connector-c++ source. Extract it. Go in extracted folder in command prompt.
Create BLD forder
Go in BLD folder through command prompt
Run this command (Make sure we've built MySQL server before this, in Release and Debug mode. Also make sure we've downloaded Boost sources)
cmake .. -DMYSQL_INCLUDE_DIR="..\..\mysql-5.6.24\include" -DMYSQL_LIB_DIR:STRING="..\mysql-5.6.24\BLD\libmysql\Release" -DBOOST_ROOT:STRING="..\Boost\boost_1_54_0" -DMYSQL_CLIENT_STATIC_LINKING=1 -G "Visual Studio 11 2012 Win64"
It will create MYSQLCPPCONN.sln
Open MYSQLCPPCONN.sln in Visual Studio and make changes to 'mysqlcppconn-static' project:
A. Under C/C++ -> General -> Additional Include Directories put this (for All Configurations)
nativeapi;..\;..\..\;..\cppconn;..\..\cppconn;..\..\..\mysql-5.6.24\include;..\..\..\mysql-5.6.24\BLD\include;..\..\..\Boost\boost_1_54_0
B. In Code Genaration, change Runtime Library to Multithreaded (Debug or non-Debug depends on configuration) and NOT DLL
C. Under Librarian -> All Options keep "Additional Options" and "Ignore Specific Default Libraries" to blank (for All Configurations)
D. Under Librarian -> General keep "Ignore Specific Default Libraries" to blank (for All Configurations)
Build only 'mysqlcppconn-static' library project (as only this would be needing by application to connect to MySQL server)
This would generate library in mysql-connector-c++-1.1.5\BLD\driver\< Configuration > folder which we link in our project.

I was making a 2048 game on Code::Blocks, but due to debugging problems, I move to Visual Studio Community 2017. It seems that conio.h doesn't work there, so I'm trying to switch to curses.h library.
I've read a lot of tutorials, but none of them worked for me. I visited their website and downloaded the .zip file with 384 kilobytes (KB), but I do not know what to do with these files.
Help, please?
I have found a very useful website which talks about PDCurses and its installation in Visual Studio. Even though it is for 2010/2013, it really worked for me in VS2017 — even the demo programs (with very minute changes)!
So here is the steps I did (since you already have PDCurses):
Take the developer command prompt of VS2017 community edition and type
in set PDCURSES_SRCDIR=<PDCurses Directory Location>; in my case it
was
set PDCURSES_SRCDIR=C:\pdcurses-master
Note: Here we are setting up the environment variable needed for compilation. If you need additional functionality defined by the pdcurses library, you may want to set corresponding variables in this step. For example, if you need wide character support, you can use set WIDE=1. To see what all are the options available, you can open up the make file (mentioned in next step) in any text editor and look for if conditionals.
Navigate in the command window to the directory of PDCurses/win32 (in my case C:\pdcurses-master\win32)
nmake –f vcwin32.mak
(This is the make file for PDCurses.) It will create the pdcurses.lib for our Visual Studio.
Now we need to incorporate the generated library into our project. So open up your project and go to project properties
In “VC++ Directories”, change:
Include directories: Add a new file-path to PDCurses installation directory, in my case it is C:\pdcurses-master.
Library directories: Add a new file-path to PDCurses installation library directory, in my case it is C:\pdcurses-master\win32.
In C/C++:
In “Code Generation” tab, change “Runtime Library” to “Multithreaded Debug (/MTd)”. (Usually, it is set already)
In Linker:
In “Input” tab, add pdcurses.lib to Additional Dependencies (I initially got confused - remember, it is the input tab of linker)
Click on Apply, and OK.
Then wow! I ran some sample programs (demos) from the pdcurses project and all of them worked for me with very slight modifications.
Note: I created a Windows (also known as Win32, as in Win32 API) console application with Visual Studio 2017 and loaded the project. I did include stdafx.h and compilation was successful and I was able to see the output in the terminal window.
The above website also provides a PDF document too. The instruction there starts from the downloading the pdcurses from website.
This is old news now, but it might help somebody to know that pdcurses is packaged up on vcpkg.
To use it, (assuming you have vcpkg installed, of course, (Installing vcpkg) )
vcpkg install pdcurses
and you're off to the races. vcpkg will take care of making sure the include and library paths are all set.
While my primary domain of expertise is not Visual Studio 2015 setup / project configuration, I have experienced troubles on loading / configuring ZeroMQ project.
How to proceed correctly on loading a ZeroMQ Project?
Observed errors:
current build on github and even old "stable" versions cause cmake errors
ZeroMQ Installer does not support Visual Studio v14
Instructions would be awesome, as it seems that there is no other source of documentation for this situation on the internet.
Had the same problem a while ago. Here is what I did to solve this:
Download the right ZMQ version
The "download link" provided on the ZMQ website seems outdated.
To really get the current version you would have to use Git:
git clone https://github.com/zeromq/libzmq.git
Build with Visual Studio 2015
The repository comes with a pre-build Visual Studio project. You can find it in ...\libzmq\builds\msvc. To build for Visual Studio 2015 cd into vs2015 and open libzmq.sln.
You can choose if you want to compile static or dynamic libraries: DynRelease or StaticRelease for either Win32 or x64.
After that, run Build > Build solution to compile everything.
Setup project to use compiled libraries
After you created your project, go to the project's properties:
C++ > General > Additional Include Directories should point to the include path of the repository. If you want to use C++ style some additional files have to be placed in this directory. Alternatively you can take a look at https://github.com/zeromq/zmqpp.
Linker > General > Additional Library Directories should point to the built libraries. They should be located at ...\libzmq\bin\x64\Release\v140\dynamic\.
Linker > Input > Additional Dependencies should contain the name of the library you want to use. The default should be libzmq.lib, otherwise you will find the name in the bin directory.
The program depends on the libzmq.dll file you just built. This file has to be placed within your project's build directory. To achieve this, you can add the following command to Build Events > Post-Build Event > Command Line:
copy /Y "...\libzmq\bin\x64\Release\v140\dynamic\libzmq.dll" "$(OutDir)"
This will copy the .dll file to the destination directory on every build if it's missing.
Hope this helps =)
When i build the boost library, with the vs 2013 developer prompt,
>bootstrap
>b2
it will generate the lib files in an subdirectory:
bin.v2
every library is now saved as follows(example):
<path>\boost_1_55_0\bin.v2_x64\libs\log\build\msvc-12.0\debug\address-model-64\architecture-x86\link-static\log-api-winnt\threading-multi\libboost_log_setup-vc120-mt-gd-1_55.lib
Now when i try to build an app which uses logging, i will get an linker error because the
file 'libboost_log_setup-vc120-mt-gd-1_55.lib'
could not be opened. Now, when i specify the location of this file in the linker properties of my project and rebuild it another file is missing:
libboost_system-vc120-mt-gd-1_55.lib
rinse and repeat and yet another dependency will pop up, libboost_date_time-vc120-mt-gd-1_55.lib and so on, is there a smart way to solve this problem? like building the boost libraries in a way that the boost build programm will put them in one single folder or can i configure visual studio to search recursively for the libs?
Someone else asked a question on how to build x64 libs with bjam: 64-bit version of Boost for 64-bit windows
the answer also contained the answer to this concrete question:
after the bootstrap command, the bjam command goes as follows:
bjam --toolset=msvc-12.0 --build-type=complete allthelibs
where --toolset=msvc-12.0 corresponds to visual studio 2013
and allthelibs will be the subfolder containing all the boostlibs
I am having trouble getting LibCurl to work with Visual Studio 2013. I downloaded the current version (curl-7.33.0) and tried following the instructions I found on this site: Using LibCurl with Visual 2010
But I can't find curllib.lib in the folder I downloaded. And I am still getting errors:
After searching the internet for more help. I now get these error messages. There appears to be a problem with linking to libcurl.lib?
This is what I have configured:
Inside /lib I have libcurl.lib and libcurl.dll
UPDATE
I downloaded this release for Win32 MSVC: http://curl.haxx.se/download.html#Win32
After adding the libcurl libraries and successfully compiling, I am now getting this error message:
The application was unable to start correctly (0xc000007b). Click OK to close the application.
Here is the sample code I am trying to run:
#include <iostream>
#include <stdio.h>
#include <curl/curl.h>
int main(void)
{
CURL *curl;
CURLcode res;
curl = curl_easy_init();
if (curl) {
curl_easy_setopt(curl, CURLOPT_URL, "http://google.com");
res = curl_easy_perform(curl);
/* always cleanup */
curl_easy_cleanup(curl);
}
return 0;
}
FINAL UPDATE
I believe I have gotten LibCurl to work with Visual Studio 2013 now. Persistence ftw!
Although, after spending hours trying to solve these error messages, I am a little hesitant at saying everything is working fine now. That is why I am putting a bounty on this question to get clear and concise instructions on getting LibCurl to work with Visual Studio 2013.
This is what I did to get it to work:
First, download the Win32 MSVC package here: http://curl.haxx.se/download.html#Win32
For these instructions sake, let's say you downloaded to C:\LibCurl
Start a new project in Visual Studio. Go to Project|Project Properties|VC++ Directories|Include Directories|
Add the path to the include directory inside the downloaded package. (C:\LibCurl\include)
Next, go to Project|Project Properties|Linker|General|Additional Library Directories|
Add the path to the lib directory. (Where curllib.dll is located)
Then, go to Project|Project Properties|Linker|Input|Additional Dependencies|
And add curllib.lib
Now if you compile a test program, you will likely get the message saying libsasl.dll is missing. You will need to download this file and put it in the same directory as your build.
I used 7-Zip to extract libsasl.dll from OpenLDAP for Windows. OpenLDAP for Windows
This is the result of my test code from above:
A lot of these instructions are out of date because they recommend the win32-ssl-devel-msvc package for curl, which no longer exists.
The following instructions allow you to build libcurl using only:
Visual Studio 2013
curl generic source tarball (tested on curl 7.44.0).
A. Build libcurl static library
Download the latest curl generic source from: http://curl.haxx.se/latest.cgi?curl=tar.gz
Extract the source to a local directory (we'll be using C:\libcurl)
Open a command prompt
"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\vcvars32.bat" To initialize your VC environment variables (adjust your VS 2013 installation directory as needed)
cd C:\libcurl\winbuild
nmake /f Makefile.vc mode=static VC=12
The build should appear in C:\libcurl\builds\libcurl-vc12-x86-release-static-ipv6-sspi-winssl
B. Link Against libcurl in Visual Studio
In Visual Studio, right click your project in Solution Explorer, then click "Properties"
Configuration Properties > C/C++ > General > Additional Include Directories: add C:\libcurl\builds\libcurl-vc12-x86-release-static-ipv6-sspi-winssl\include
Configuration Properties > C/C++ > Preprocessor > Preprocessor Definitions: add CURL_STATICLIB
Configuration Properties > Linker > General > Additional Library Directories: add C:\libcurl\builds\libcurl-vc12-x86-release-static-ipv6-sspi-winssl\lib
Configuration Properties > Linker > Input > Additional Dependencies: add libcurl_a.lib
C. Call libcurl from Your Project
The following sample shows a call to libcurl:
#include "stdafx.h"
#include <curl/curl.h>
void main(int argc, char* argv[])
{
CURL *curl = curl_easy_init();
if (curl) printf("curl_easy_init() succeeded!\n");
else fprintf(stderr, "Error calling curl_easy_init().\n");
}
I would say that in a comment, but I am lacking in points.
You don't have to copy any .dll into your program run catalog.
Go to Project | Properties | Configuration Properties and in line Envrionment write: PATH=$(ExecutablePath)$(LocalDebuggerEnvironment).
From now on, all .dlls from any catalog you mention in Project|Project Properties|VC++ Directories|Binary should be usable without copying them.
The rest is exactly as you written.
The easiest way to do this that I found is first make sure that nuget is installed.
http://www.nuget.org/
Then create your project.
Then go to http://www.nuget.org/packages/curl/ and follow the instructions which is to go the package manager console and type PM> Install-Package curl
If you then look for the packages directory in your project directory, you will find the include files and the library files. Note that there is a version for Visual Studio 110, not 120, but because libcurl is a C library you can use it with Visual Studio 2013. Make sure the include directory and lib directory are specified under the Visual C++ directories in project properties.
Make sure you have the following files as addition input to the linker
libcurl.lib;libeay32.lib;ssleay32.lib;Ws2_32.lib;libssh2.lib;zlib.lib;wldap32.lib;
Another way to use curl/libcurl is build with CMake v2.8.12+ (assuming that git is already installed on your computer)
Open cmd window and change dir to appropriate folder
git clone https://github.com/bagder/curl.git
mkdir msbuild
cd msbuild
cmake ..\curl -G"Visual Studio 12 Win64" -DCMAKE_INSTALL_PREFIX=C:\curl.vc12 -DCURL_STATICLIB=ON
< ... lots of output here ... >
Open generated CURL.sln in Visual studio and build it.
CMake options I use in example
-G selects build generator. In our case Visual Studio 2013 64 bit target
-DCMAKE_INSTALL_PREFIX - provides root folder where targets should be installed
-DCURL_STATICLIB=ON - generates build for static library
After building install target, your will find bin/include/lib folders in C:\curl.vc12
Provide those path to your solution and build your code with curl lib.
I tried to do it from scratch with VS2012 (I don't have 2013) and it works perfectly.
I downloaded version 7.19.3 from http://curl.haxx.se/latest.cgi?curl=win32-ssl-devel-msvc because it's the only available version for VS.
I added the include directory, not the curl directory as he says in the tutorial.
I compiled a small toy project without any problem.
So, I'm not sure what your problem is, but:
Make sure you download the right archive.
Try to put the cURL folder on a path without space.
If you know someone who use VS2012 or older, try your code with the same include and lib and see if it works.
Paste a minimal working example of your code so I can test it.
This is a bit late, but for those who still have problems, this method worked best for me:
Add VS to the system PATH:
For example: C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin.
Download current curl-X.zip from http://curl.haxx.se/download.html and unzip.
Open command line at curl-X/winbuild.
Call vcvars32.bat.
Call nmake /f Makefile.vc mode=static VC=12.
Goto curl-X/builds/libcurl-XXX.
There you find the includes and a libcurl_a.lib.
This lib works fine for me.
Remember to define -DCURL_STATICLIB when you compile your code with this lib.
For Visual Studio 2017, the steps in link worked for me. In case the link expires or specifically for those who download the libcurl zip file instead of cloning from GitHub, I will note down the steps here.
Set environment variables with “C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat” x64. If the command is successful, you will see a message that says Environment initialized for 'x64'
Download and extract the compressed libcurl file from download libcurl. I used the .zip file.
cd into winbuild directory inside the extracted libcurl folder.
Run nmake /f Makefile.vc mode=dll MACHINE=x64 to build. For more information on build options, please refer to BUILD.WINDOWS text file in winbuild folder.
Go up one directory level and cd into builds folder to find the compiled files.
All the best!
The problem is that the targets for the default VS2013 platform tools are not set in the NuGet packages. This is why it works in VS2012 but not VS2013. I manually created replacement targets files. Instructions and download:
https://github.com/evoskuil/curl-nuget-targets
Download the curl v7.37.0 source code and use the Visual Studio project files provided.
I've spent the last few weeks polishing my own personal project files, that were based off the original VC6 files, and adding them to the repository.
.dsw / .dsp (VC6), .sln / .vcproj (VC7, VC7.1, VC8 and VC9 as well as .sln / .vcxproj (VC10, VC11 and VC12) files are provided for both DLL and Static Library builds with support for OpenSSL and Windows SSPI / SChannel in both Win32 and x64 configurations.
I found an easy way to get it work in VC++ using the latest package. I basically followed the steps in Using libcurl in Visual Studio. The libcurl and VC++ are very old in the instruction.
First download the ZIP file on download page https://curl.haxx.se/download.html The ZIP package is https://curl.haxx.se/download/curl-7.50.1.zip
Go to projects-> Windows\VC10 (or your version of VC)\lib\libcurl.sln, open the project in VC++.
Build the project in DLL Release. DLL debug doesn't work on my VC++.
Go to build\Win32\VC10\DLL Release, you can find the lib and dll files generated from previous step.
Create a folder new, with include and lib folders. Copy the libcurb.dll and libcurb.lib whatever is in the DLL Release folder to the new\lib. Copy everything in curl-7.50.1\include to new\include folder.
C++ Properties -> Configuration Properties -> VC++ Directories, add new\include to Include Directories, new\lib to Library Directories; add new\lib to Linker -> General -> Additional Library Directories, add libcurl.lib to Linker -> Input -> Additional Dependencies
It seems that I have to put the dll file under the same folder with executable file.
It should work.
I have downloaded c++ open source application which was created using under Linux IDE/Editor (or maybe something NOT Windows) and its no longer supported.
This time I want to edit and recompile it using VS 2010.
Error(s) left (mostly prefixed with "wx") such as:
"wxString is undefined"
"wxStaticText expected a type specifier"
etc... makes me think that this is all about wxWidgets.
After successfully building wxWidgets, what to do next to integrate it to the actual c++ program for me to be able to edit and compile using VS 2010?
I use BorlandC++ last 2 years ago but not familiar with GUI packages.
The first step is to tell the compiler where to look for the wxWidgets include files.
So, you need to find out where these files are, which depends on where you installed and built wxWidgets.
On my system, this is C:\Program Files (x86)\wxWidgets-2.8.12
I consider the best way is to, instead of hard-coding the path in every project, create an environment variable WXROOT to store the path to your wxWidgets folder.
Control Panel | System | Advanced | Environment variables
Now you have to tell the compiler about this
Visual Studio | Project | Properties | C/C++ | Additional Include Directories
What you add here depends on what kind of build you are doing. If you are doing a unicode release build, then this will be a good start
"$(WXROOT)\lib\vc_lib\mswu";"$(WXROOT)\include"
Now you should have fixed your compiler errors.
Next you will get some linker errors ....
Maybe the errors are caused because you are using wxwidget 2.8 which is unsupported in VS 2010.
Try building wxwidgets 2.9 or use VS 2008. I had no problem building wxwidgets 2.9 on VS 2010.
Wxwidgets site home says "While this is still officially a development release because some API details are still not frozen, we believe that 2.9.3 can be used in production environment".
About what to do after successfully build it, take a look at this http://wiki.wxwidgets.org/Microsoft_Visual_C%2B%2B_Guide
You may want to use the tutorial of the section "Creating a new project from a sample" 'cause creating a project by hand is a little bit complicated as wxwidgets requires some extra configuration and not just to set and include and libs dir as most of the libs does.
Here is a video which shows how to start with Visual Studio.
Also you can take a look at samples directory and create your own project based on configuration of projects from that directory.
May be I am little bit late , But this will help newcomers to wxwidgets.
First of all Goto Wxwidgets directory(to download path) in my case it is "C:\Users\WxWidgets_all".
Now in that folder goto build directory.Now open Visual Studio Command prompt. If you have already installed Visual Studio then you can easily find it through start menu.
Now in command prompt go upto <Path to your wxWidgets>/build/msw/ . Now run Following Commands.
nmake /f makefile.vc--For Static Library and Debug Version
nmake /f makefile.vc SHARED=1--For SHARED Library and Debug Version
nmake /f makefile.vc BUILD=release--For SHARED Library and Release Version
After completing it , you will have dll or lib in "<path to wxwidgets>\lib\" depending on option provided in above commands.
Now include all files related to wxwidgets in your project.Mainly two paths are required to include "<path to wxwidgets>\inlcude\" and "<path to wxwidgets>\lib\vc_<lib\dll>".
After that link your wxwidgets generated library to your project.To do this inlcude "<path to wxwidgets>\lib\vc_<lib\dll>" to your project property in library section.
Now add below preprocessors to your project.
_WINDOWS
NDEBUG(For Release)
_DEBUG(For Debug)
_CRT_SECURE_NO_DEPRECATE=1
_CRT_NON_CONFORMING_SWPRINTFS=1
_SCL_SECURE_NO_WARNINGS=1
__WXMSW__
_UNICODE
After that add following library to your project from "<path to wxwidgets>\lib\vc_<lib\dll>"
wxbase30u_net
wxmsw30u_core
wxbase30u
wxtiff
wxjpeg
wxpng
wxzlib
wxregexu
wxexpat
wxmsw30u_adv
Based on your compiled options , library name can be little bit different.
I think I have covered all the steps to run wxWidgets.
Even if you got errors , You can check minimal project in "<path to wxwidgets>\samples"
directory. Try to run that project , and even if you got error then your wxwidgets is not built properly.
Hope this will help.
