I opted for the .msi solution that I picked here: http://www.confusedbycode.com/curl/ and tried to link that to my project... However I am still getting some errors after doing http://stackoverflow.com/questions/31909228/link-curl-in-vs12 what I thought was right: 1>main.obj : error LNK2019: unresolved external symbol _curl_easy_init referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _curl_easy_setopt referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _curl_easy_perform referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _curl_easy_cleanup referenced in function _main My configuration in my project vs12 is the following: I included the include folder and the the lib folder in the vc++ directories I added CURL_STATICLIB to the Preprocessor definition in C/C++ section as well as adding the proper include folder I added the lib folder to the Linker sectio as well as libcurl.lib Eventually I just included "curl.h" to the relevant .cpp file... Is there something that I am missing? Thank you a lot c++ visual-studio-2012 libcurl share|improve this question asked Aug 9 '15 at 21:58 trexgris 669 As from your steps stated you actually missed to add -lcurl to the list of your linked libraries. –πάντα ῥεῖ Aug 9 '15 at 22:02 thank you for your answer.

On linux platform, I have finished this job by : /configure --disable-shared --enable-static --with-ssl=/usr/local/ssl --without-zlib --disable-ldap --disable-ldaps make But to windows, I have edit a batch file build.bat as: call "c:\Program Files (x86)\Microsoft Visual Studio 8\VC\vcvars32.bat x86_amd64" set CFG=release-ssl set OPENSSL_PATH=C:\cindy\openssl-0.9.8k\openssl-0.9.8k nmake.exe -f Makefile.vc8 And, add these lines to curl-7.21.3\lib\Makefile.vc8 : CURL_DISABLE_LDAPS = true CURL_DISABLE_LDAP = true Then I run the build.bat, generate libcurl.lib. But, when I use this libcurl.lib in another project, I still get error when compile my project like: libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ldap_unbind_s referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ldap_msgfree referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ldap_next_entry referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ber_free referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ldap_next_attribute referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ldap_memfree referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ldap_value_free_len referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ldap_get_values_len referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ldap_first_attribute referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ldap_get_dn referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ldap_first_entry referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ldap_search_s referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved external symbol __imp_ldap_simple_bind_s referenced in function Curl_ldap libcurl.lib(ldap.obj) : error LNK2019: unresolved exte
