I downloaded the xlnt library for working with Excel - https://github.com/tfussell/xlnt. Can you please tell me what to do with it further? Honestly, I still can’t understand how among all the files there are in the downloaded archive, and there are 100 of them .hpp and .cpp files, what should I do with them?
1)As far as I understand, they need to be processed by the Cmake program and it seems that the output should appear .lib file, but I absolutely can’t understand how to do it or maybe something else
2)Or how can they be directly processed by Visual Studio 2017?
PS:When I launch Smack, I select the Source folder, the Cmake generates many incomprehensible files, but among them there is not one file with the .lib extension.
Help me please.
With CMake you can obtain the visual studio 2017 project files
and then compile the xlnt library.
Unzip the archive file
Within the xlnt folder, create a new directory and call it build
Launche CMake (GUI)
Browse for the source code folder
Browse for the build folder xlnt/build
With the Configure button select the tool (IDE/compiler) that you want to use
Pressing the Generate button, CMake will generate (inside the build folder)
the visual studio 2017 project files you need to compile the xlnt library
Building the solution, VS 2017 produces the xlnt.lib, xlnt.exp and xlnt.dll files.
The source path you see in the CMake screenshot is incorrect. You must specify the path that contains the "top level" CMakeLists.txt file.
The correct directory is: C:/Users/Zver/source/repos/XLNT Library/xlnt-master.
The CMakeLists.txt file in the above directory tells CMake all necessary subdirectories.
At this point you will see the static compilation option of the library appear.
If you use the MinGW/GCC compiler you must prevent the path from containing empty spaces.
Then you need to rename the directory from "XLNT Library" to "XLNTLibrary". At this point the path would become:
C:/Users/Zver/source/repos/XLNTLibrary/xlnt-master.
I want to use Aquila DSP to compute MFCC features in my project and trying to make it work.I followed this tutorial but after mingw32-make install on the source code pulled from Aquila's git repo, it generates only libAquila.a in lib folder. I tried changing my project's include and library dependencies using these generated files after install. Also tried adding FindAquila.cmake and tried building my project with cmake for VS 2012, still no luck. Keep getting "aquila/global.h" no such file or directory when I try to include "aquila/global.h".
I also tried building Aquila with cmake for VS 2012 and able to compile it and it generates .lib files as well, but not sure how to proceed with that.
If anyone knows how to make it work, it will be great help.
So, I made it work with Visual studio 2013. Now what I am doing is I am building Aquila with both Mingw and with VisualStudio. Mingw gives required include files and visual studio build gives required .lib files. I am building Aquila in VS 2013 with configuration type static lib (project properties >> General >> Configuration type) for both debug and release configuration and then I build the project.
For Mingw, first I use cmake GUI with mingw cmakefiles configuration and then run mingw32-make install in the build directory, which will put the include, lib and share files in the installation directory( usually C:\\Programme files\\Aquila.
Now I create a Folder Aquila and put include and share from above path and create a new folder lib with two subfolder debug and release. Here I put two .lib files in each folder (aquila.lib and Ooura_fft.lib) (debug libs in debug and release libs in release folder, they will be VS build folder). Once this is done, in my project setting, I add Additional include directories under C++ >> general, Addiotnal library path under linker >> general and names of libraries under linker >> input for both bebug and release configuration. After doing all these things, now the library works with my project.
I am trying to use cmake to build the box2d library for visual studio 2012. This is what I have in cmake:
The Box2D/Box2D directory has all of the source files in it and the Box2D/Build directory is where I want to put all of the library things. I selected the visual studio 11 compiler and it compiled and generated without errors. However in the build folder I can't find any .lib file. This is what generates in the build folder:
I went through all of these directories but not one had any box2d.lib file in them. I don't know what I'm doing wrong. Help please?
Cmake only generates the build files so you can build it with the tool you choose in cmake - Visual Studio in your case. It only generated the Visual Studio project files. You have to open those files to build your library.
I fixed it! I built some projects in Project.sln and some .lib files were generated. I was thinking cmake was supposed to do that for you.
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 downloaded cpptest from internet, and I want to build it using Visual Studio 2008.
The problem is that instead of .sln and vcproj file, Makefile.am is distributed, and I believe that all the all the necessary included file is included in the Makefile.am.
How to use Makefile.am to generate VS project files? I tried to use Cmake, but there is no CMakeList in the distribution.
Edit: Thanks to all the answers! There is a sln file distributed after all. But I am still interested to know the answer to my original question.
the visual studio project files for cpptest are in the win directory, not in the src directory where the makefile is..
edit
makefiles are meant to be used with GNU make. If you want that on windows, you can look at Mingw, GnuWin32 or Cygwin. But they also require gcc for compiling, so you won't really be using VS.
However, for most projects that do not have external dependencies it's no big deal if you do not have the VS project file: after all a makefile is just a list of the source files and some compilation options. To successfully build projects like cpptest, you could just create an emtpy VS project, add all source files to it, set output type to executable, build it and you're done. Eventually you can tune optimization options, but for the rest the default options will just do fine.
Go to win\VisualStudio.NET and you will find a VS solution file.
I just downloaded the archive and found the .sln file. It is under: /win/VisualStudio.NET. You can open that with VS2008 and update it, it should work.
