Building libcurl with SSL support on Windows

Question

I\'m using libcurl in a Win32 C++ application.

I have the curllib.vcproj project added to my solution and set my other projects to depend on it.

How do I bui

Answer 1

In my case follow the curl README file was enough.
My configuration is the following:

• Visual Studio 2015 (VC14)
• Static library
• Win64
• curl version 7.57.0
• OpenSSL 1.0.2

Compilation of libCurl

1. Download libcurl source there: https://curl.haxx.se/download.html
2. Uncompress the file and go to the folder curl-7.57.0\projects
3. Open the README file and follow the instructions, this lead me to do the following:
   • Downloaded OpenSSL
   • Extract it and rename it to openssl, put it aside the curl folder, this is important as you'll open the VS project that expect to find openssl there.
   • Install Perl
   • Execute the utility build-openssl.bat to perform the compilation of openSSL. With my settings this became the following:
     .\build-openssl.bat vc14 x64 release ..\..\openssl\
     just runs .\build-openssl.bat -help to know more about the parameters.
     After that you can see OpenSSL has been compiled as you got a new folder here: openssl\build\Win64
4. Open the Visual Studio project curl-7.57.0\projects\Windows\VC14\curl-all.sln
5. Be sure to set the visual studio project to the build configuration you need (LIB Release - LIB OpenSSL in my case)
6. Build all
7. The library is located at curl-7.57.0\build\Win64\VC14\LIB Release - LIB OpenSSL\libcurl.lib

Remarks

• Don't forget to define the CURL_STATICLIB preprocessor in your own project
• With static library, you will have to links with the dependencies of libcurl, see this answer
• You might not want to depend on LDAP, in that case you can disable it by setting the preprocessor CURL_DISABLE_LDAP before you compile libcurl.
