How do you properly install libcurl for use in visual studio 2017?

Tags:

I am just starting out in c++ and cannot figure out how to add libraries, in particular libcurl. I tried a bunch of tutorials but most were for 2013/10 or didn't work. Can anyone please explain (Preferably in standard/non technical English) how I can add the library? I have already tried adding it in the include section of the program and in the additional dependencies menu.

Note this is a re-post I asked virtually the same question around 3 days ago to which I received no replies. Not sure if that is because its very easy and I should have figured it out my self, or if it just got buried in a flood of questions, or some other reason. In any case sorry for the re-post.

How do I add libcurl to Visual Studio?

Go to lib directory and double click on “curllib. dsw” which is the Visual Studio Project file for curlib. It will start the Visual Studio with correct configuration and settings. Of course you need to have Visual Studio installed on your machine.

Here's how I've got curl to work with Visual Studio 2017 15.9.14:

  1. Download curl zip package from https://curl.haxx.se/download.html (latest verified is: https://curl.haxx.se/download/curl-7.70.0.zip)
  2. Extract downloaded package to a folder of your choice (e.g. C:\curl\)
  3. Open Developer Command Prompt for VS 2017 (see Windows Start menu or %PROGRAMDATA%\Microsoft\Windows\Start Menu\Programs\Visual Studio 2017\Visual Studio Tools\) and cd to C:\curl\winbuild\
  4. Run nmake /f Makefile.vc mode=static. This will build curl as a static library into C:\curl\builds\libcurl-vc-x86-release-static-ipv6-sspi-winssl\
  5. Create a new project in Visual Studio (e.g. a Windows Console Application)
  6. In Project Properties -> VC++ Directories -> Include Directories add C:\curl\builds\libcurl-vc-x86-release-static-ipv6-sspi-winssl\include\
  7. In Project Properties -> VC++ Directories -> Library Directories add C:\curl\builds\libcurl-vc-x86-release-static-ipv6-sspi-winssl\lib\ there
  8. In Project Properties -> Linker -> Input -> Additional Dependencies add libcurl_a.lib, Ws2_32.lib, Crypt32.lib, Wldap32.lib and Normaliz.lib
  9. Try to build a sample program:
#define CURL_STATICLIB #include <curl\curl.h>  int main() {     CURL *curl;      curl = curl_easy_init();     curl_easy_cleanup(curl);      return 0; } 

Alternatively you can use vcpkg to install curl:

  1. Get latest vcpkg zip file from https://github.com/microsoft/vcpkg/releases (e.g. https://github.com/microsoft/vcpkg/archive/2019.09.zip) and extract it to a folder of your choice (e.g. C:\vcpkg\)
  2. Open Developer Command Prompt for VS 2017 (see Windows Start menu or %PROGRAMDATA%\Microsoft\Windows\Start Menu\Programs\Visual Studio 2017\Visual Studio Tools\) and cd to C:\vcpkg\
  3. Run bootstrap-vcpkg.bat
  4. Run vcpkg.exe integrate install
  5. Run vcpkg.exe install curl
  6. Create a new C++ project in Visual Studio and you're ready to go - try it with the example above. There's no need to modify project settings.
