Linker errors when statically linking libcurl+openssl to my project

I am trying to statically link libcurl (with SSL) into my project, but I am encountering lots of linker errors:

Here is the list of files in lib folfer that I downloaded.

I was told that I should define the macro CURL_STATICLIB and link in wsock32 and wldap32. Is there anything else that I should be doing?

I am using MinGW and Eclipse.

g++ -DCURL_STATICLIB -DUSE_LIBSSH2 -DHAVE_LIBSSH2 -DCURL_DISABLE_LDAP -DHAVE_LIBSSH2_H -DLIBSSH2_WIN32 -DLIBSSH2_LIBRARY -DUSE_SSLEAY -O0 -g3 -Wall -c -fmessage-length=0 -osrc\CURLDown.o ..\src\CURLDown.cpp

g++ -L../lib -oCURLDown.exe src\CURLDown.o -lcurl -lcrypto -lwsock32 -lwldap32 -leay32 -lidn -lrtmp -lssh2 -lz -lssl32 -lssl

For those searching for this answer on google - the undefined reference to `CreateDCA@16' linker error is looking for libgdi.a (just -lgdi would do). Bear in mind it has to be included after libcurl and openssl in the list of libraries to link.

g++ -L../lib -oCURLDown.exe src\CURLDown.o -lcurl -leay32 -lidn -lrtmp -lssh2 -lz -lssl32 -lcrypto

suggests that you really don't specify all libs. Maybe there is a typo in your makefile? I also see a reference to timeGetTime() which resides in Winmm.lib.

Also libeay32 and libcrypto seem to have a misunderstanding in who should define what. There is probably accidently a sourcefile that is compiled by both libs that should only be compiled by one.
