According to : http://aluigi.freeforums.org/post4997.html
link it to libcrypto.a, it's the static library.
if you don't have it:

I have a project in VC++ where I am using libcurl library. Even after adding the library in Additional Dependencies I am facing around 150 unresolved external errors, all majorly for libcurl_a.lib file.

I have solved this problem by building the library with RTLIBCFG=static option.
I'm working on an existing C++ project. We include libcurl as a static library, which we build from source. I'm trying to upgrade us from version 7.38.0 to version 7.61.1.
I downloaded curl-7.61.1.zip from here: https://curl.haxx.se/download/.
I made no modifications to the source and did not run any scripts that came with curl 7.61.1.
We have an existing VS solution we used for compiling curl 7.38.0, so I started from that and modified as needed for the new files in curl 7.61.1.
Everything compiled fine, however, when I try to link the compiled result into my project, I get the following errors:
1>libcurl.lib(schannel.obj) : error LNK2019: unresolved external symbol __imp_CertOpenStore referenced in function schannel_connect_step1

Has anyone run into similar issues before? Please let me know if I need to edit this with more info as well.
As Peter mentioned in a comment, I needed to link against windows libraries. In this case, linking against crypt32.lib solved the issue for me.
I hava a problem in using mongo-c-driver in VS2010.
I used mongo-c-driver-1.2.0/VS2010/Win7-64bit;
Follow the steps in API document, I got four lib files.(I used cmake and VS2010 to build)
bson-1.0.lib bson-static-1.0.lib mongoc-1.0.lib mongoc-static-1.0.lib
And in my test program ,I put follow #pragma comment:
#pragma comment(lib,"bson-1.0.lib")
#pragma comment(lib,"mongoc-1.0.lib")
#pragma comment(lib,"bson-static-1.0.lib")
#pragma comment(lib,"mongoc-static-1.0.lib")
But it return some link error said
error LNK2019: unresolved external symbol _mongoc_cleanup
error LNK2019:unresolved external symbol _mongoc_client_destroy，

Does anyone have idea about this problem. TAT.
I have downloaded EasyHook 2.7 source and I try to compile it in my Visual Studio 2012 environment.
After solving a lot of warnings, I have found other warnings that I cannot solve, and these are:

1>C:\Users\Jaime Stuardo\Downloads\EasyHook-2.7.5159.0-Source\\Debug\x86\EasyHook32Drv.sys : fatal error LNK1120: 9 unresolved externals
What lib files I need to add so that the linker will not fail? notice that the first 2 functions belong to Windows API, so it is very curious it does not link.
Regards
Jaime
For the Windows functions, just look them up on MSDN. CoTaskMemAlloc says you need to link OLE32.LIB. CopyMemory says KERNEL32.LIB. The functions beginning with ud come from a library which Easyhook depends on: "EasyHook makes use of the udis86 library by Vivek.
I try to compile VC++ application and get the error message as below. Is there anyone who know what the library I may be missing? Any advice & suggestion are appreciated.
