This question is not a duplicate of cannot open file 'SDL2.lib' which discusses this same error but my problem is that I don't have an SDL2.lib file, if I can just see it I can make this work
I'm trying to set up the development environment for SDL2 by following Lazy Foo's tutorial.
Setting up SDL 2 on Visual Studio 2010 Ultimate
The tutorial is for Visual Studio 2010, I'm using Visual Studio Community Edition 2017. Is that a problem?
The problem starts when linking the libraries, there is no x86 or x64 folder inside the lib directory of SDL2's Windows Development libraries that I downloaded from SDL version 2.0.8 (stable).
So I specified it as lib/ instead of lib/x86 as it says in the tutorial.
These are the files inside the lib folder
$ ls
cmake/ libSDL2.dll.a libSDL2_test.a libSDL2main.a pkgconfig/
libSDL2.a libSDL2.la libSDL2_test.la libSDL2main.la
When building VS2017 is throwing an error saying that Cannot open file 'SDL2.lib'. Yeah, there is no such file. Do I need to do an additional step to get this file?
When I configured for CodeBlocks it works fine. What exactly am I doing wrong here? This may have an obvious answer but I'm not able to find it.
Library name `libSDL2.dll.a' indicates that it is not meant for use with VS C++ ( for dynamic link you need dll + lib, for static link you need only the lib ). You can construct a lib file from dll using dumpbin.exe and lib.exe. Your options are:
1) Download SDL source file in zip format from GitHub and create you own binaries.
2) Use vcpkg and install in just one command line ( recommended).
3) Download the SDL binaries from internet. ( you can have linker issues if the project configurations doesn't matches yours)

I'm having trouble using Point Cloud Library with Microsoft Visual Studio 2017.
I have installed [PCL-1.8.1-AllInOne-msvc2017-win64.exe] and I've followed the steps mentioned
here. to link it to my Visual Studio 2017 project.
My problem is that Visual Studio is not finding the header nor the source files of the library I need.
The error I'm getting is as follows:
[fatal error C1083: Cannot open include file: 'pcl/io/pcd_io.h': No such file or directory]
To be more precise about my problem, I need to include three PCL header files in order to run thisIterative Closest Point Tutorial
I've followed the following steps to include the PCL into my project:
Added the include directories to my project at the Project Properties/Configuration Properties/VC++ Directories/Include Directories field - here I specified the path to my PCL/include directory and to all 3rd party include directories (PCL/3rdParty)
Added the library directories on the same settings page (Library Directories field) - hereI specified the path to my PCL/lib directory and to all non-header-only 3rd party libs (Boost, Flann, VTK)
Chose the libs to be used in the linker. In Project Properties/Configuration Properties/Linker/Input/Additional Dependencies field. I added all the libs required. As I'm trying to run it in debug mode for now, I've picked the "_debug.lib" library files.
Finally, I've added the PCL/bin folder to my system path variable.
Does anyone know if I'm missing something configuration-wise?
I've seen several old posts about incompatibility between older Point Cloud Libraries and older versions of Visual Studio. As far as I understood, the new versions are supposed to work well together, but it's not the case for me.
Installing pcl is tough because there are dozens of dependencies used along with pcl software. But with with vcpkg,a command line package manager, the installation becomes just like a one liner command.
Use Microsoft vcpkg to build a static or dynamic library for your project automatically. All the dependencies like boost,tiff,openssl,flann,szip,etc will be downloaded and installed by itself. After installing vcpkg type the following on Powershell.
.\vcpkg install pcl:x64-windows-static
The link you referenced is 3-4 years old. At the time, any binary build of PCL for Visual Studio 2012 or later was not provided, and thus. PCL needed to be built with target VS. And every include/library directory of PCL and any related library have to be manually added to setup the IDE. Since PCL is a large-scale collection of libraries, this made it difficult for its users to setup VS.
Now early 2018, binary builds of PCL for VS 2015/2017 and more automatic way to setup VS (e.g., adding library/include directories) using CMake are provided. Thus, installing PCL and creating a VS project using PCL does not take more than 10 minutes. I think you'd better follow the recommended way rather than setting VS by yourself.
the previous answer use vcpkg is good,but is better to use:
.\vcpkg install pcl:x64-windows
It can let you have fewer problems.
A small note for anyone who has issues with the install listed above, occasionally an install will get corrupted and not work. I got:
LINK : fatal error LNK1201
on a build, and the solution for that is find the downloaded item. This will be located in the vcpkg/downloads/ directory. Delete the item that was having issues and try the install again.
I am new to z3. I downloaded the latest version from github and followed the instructions to build using visual studio on windows.
Now, i have to use the z3 c++ APIs in a visual studio project. I imported the code example provided in the package into a new vs project to test it but it can't recognize the z3 header file. Seems that there is some thing missed.
Can anyone guide me in how to use z3 in a vs project?
As usual for shared libraries, you have to add the folder that contains *.h to your include paths and the folder that contains *.dll and *.lib files to your library paths. Finally, add *.lib to the libraries the linker will link. There are heaps of other questions and solutions for that on stackoverflow, see for instance How to include libraries in Visual Studio 2012?.
Hello I am trying to install this library for use in one of my visual studio projects.
I know I have to go to \project properties-linker-general-additional library Directories but once I get there I don't know what to do.
I am stuck here :
Here's a step-by-step tutorial for installing, (optionally) building, and referencing boost in Windows: http://www.boost.org/doc/libs/1_61_0/more/getting_started/windows.html#get-boost
Obtain a copy of boost and put it to a folder boost_root (name as you please). If you haven't done it already, the easiest way is to get a precompiled zip from boost
Find the directory where your boost binaries are located. It usually is under the lib subdirectory, ie boost_root\libs.
Under the Additional library directory of visual studio (the one you mention in your post), enter the full or relative path to the boost dll directory, ie path_to_boost_root\boost_root\libs
I'm having a few issues getting GLFW3 set up. I've downloaded the 64-bit binaries from the official site, added glfw3.dll, glfw3.lib and glfw3.h to their respective places, specified the proper include, and added the appropriate linker input to my project. However, when I test the library with glfwInit(), VS spits this out:
error LNK1104: cannot open file 'glfw3.lib' Path/To/Project
My guess was that VS didn't know what directory the library was in, but seeing as it's in the IDE's own lib folder, I don't think this is it. Does anyone have any suggestions? Sorry if this has already been solved, I got in as deep as to read the steps of compilation before I gave up searching.
Edit: I also changed the solution platform to x64, since I am using the 64-bit GLFW binaries.
Following Andon M. Coleman's advice, I moved the headers and library folders to a new directory outside of Visual Studio's built-in ones (D:\opengl-wrappers\lib & D:\opengl-wrappers\include, for example). After including those libraries in the project settings (C/C++->General-> Additional Include Directories and Linker->General->Additional Library Directories), everything compiled beautifully.
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.
