Unresolved symbols when linking a program using libcurl
I've been using static version of libcurl, and to link my program against it properly, I had to add definition:
CURL_STATICLIB
to build configuration of my project.
Besides defining CURL_STATICLIB, for me it was also necessary to link the following dependencies (including libcurl.lib or libcurld.lib):
Ws2_32.libWldap32.lib
I ran into a similar issue - found that I was referencing the 64-bit location of libcurl.lib. Changed the link directory to the 32-bit location and the project compiled perfectly.
