I was stuck for some time with LibCurl and Visual C++ 2010 (VC10). The document Using libcurl in Visual Studio available at the Curl project’s website doesn’t help that much (notice it dates back from 2002). I searched on the internet for hints, but hadn’t find the ‘right’ solution. At the same time ** good for my ego **, I realized I hadn’t been the only one in trouble. ;-)
Below is how I got LibCurl working with VC10 (on a 32-bit machine).
First, download the latest version of LibCurl for VC10, here.
Now, create a new C++ project.
(In what follows, I assume that solutions are built in Debug mode, but it’s easy to derive the steps below for the Release mode.)
First go to Properties > Configuration Properties > VC++ Directories > Include directories. Here, add the curl directory to be found in the include directory of the unzipped Libcurl file (C:\ … \libcurl-7.19.3-win32-ssl-msvc\include\curl).
Now go to VC++ Directories > Library directories. Add the Debug directory containing curllib_static.lib, curllib.dll and curllib.lib (C:\Users\Édouard\Documents\Visual Studio 2010\LibCurl\lib\Debug).
Still in Configuration Properties, go to Linker > Input > Additional Dependencies. Here, you have to add the curllib.lib file (C:\ … \lib\Debug\curllib.lib). Type in up to name of the lib file.
The next step consists on adding curllib.dll, libeay32.dll, openldap.dll, and ssleay32.dll in the Debug directory of your project. There all are to be found in the root directory of Libcurl. You also have to add libsasl.dll in this directory. Just google for it.
(Shouldn’t this have been the first step?) Now, open the curl.h file. Replace the line #include “curl/curlbuild.h” with #include “curlbuild.h” .
