libcurl static link - undefined reference to `_imp__WSAIoctl#36' - c++

Question

I'm trying to statically link libcurl in codeblocks on Windows.
I compiled libcurl with "mingw32-make mingw32", and have linked the resulting libraries libcurl.a and libcurldll.a. I saw another post on ere that suggested the solution was to add option -lwldap32, but that's made no difference :/
What am I missing?
EDIT: Here's a sample of the first compile command that completed successfully:

Answer 1

For anyone else having this problem, turned out that I needed to add the ws2_32 lib by adding a linker settings->link library in code::blocks, using the full filename libws2_32.a.
Adding -lws2_32 as suggested elsewhere online wasn't enough for some reason.
Compile command now is:
mingw32-g++.exe -LE:\plus\libs\wxWidgets\lib\gcc_lib -o bin\Release\hlr.exe obj\Release\hlrApp.o obj\Release\hlrMain.o obj\Release\resource.res -s -mthreads -lwxmsw30u -lwxpng -lwxjpeg -lwxtiff -lwxzlib -lkernel32 -luser32 -lgdi32 -lwinspool -lcomdlg32 -ladvapi32 -lshell32 -lole32 -loleaut32 -luuid -lcomctl32 -lwsock32 -lodbc32 E:\plus\libs\curl-7.43.0\lib\libcurl.a E:\plus\compilers\MinGW\i686-w64-mingw32\lib\libws2_32.a E:\plus\compilers\MinGW\i686-w64-mingw32\lib\libwldap32.a -mwindows

Curl depends on OpenSSL. Make sure you have linked it.
_imp__WSAIoctl is a part of "Ws2.lib"(Ws2_32.lib), header "winsock2.h". Try make sure that this reference is resolved in your project.
