CURL Static Link Unresolved External Symbols

I built CURL static lib from source using this command in the x64 Native Tools Command Prompt Visual Studio

nmake /f Makefile.vc mode=static MACHINE=AMD64

I added the lib folder to the linker library folder, added libcurl_a.lib to the linker input, and added the include folder to additional include directories. I also used the pre-processor define CURL_STATICLIB.

The library links successfully and the header is found. But I get 60 unresolved external symbols when I try to compile. https://hastebin.com/vukekakoti.tex

Dynamic linking is working with no problems.

How can I solve this?

if compiling CURL with static linking, you will need to specify on the preprocessor field:

CURL_STATICLIB

and also as mentioned above, you`ll need to link with dependent libraries.

I was missing definitions contained in these libraries:

libcurl_a.lib;ws2_32.lib;wldap32.lib;advapi32.lib;kernel32.lib;comdlg32.lib;crypt32.lib;normaliz.lib

Add those to your additional dependencies.
