RE: Linker errors when statically compiled linking libcurl+openssl to my project
Hi, I am trying to statically link libcurl (with SSL) into my project but I am encountering lots of linker errors: ../lib/libcrypto.a(rand_win.o):rand_win.c:(.text+0xa9c): undefined reference to `CreateDCA@16' ../lib/libcrypto.a(rand_win.o):rand_win.c:(.text+0xaa9): undefined reference to `CreateCompatibleDC@4' ../lib/libcrypto.a(rand_win.o):rand_win.c:(.text+0xaba): undefined reference to `GetDeviceCaps@8' Looking at rand_win.c it uses CreateDCA, CreateCompatiableDC(), GetDeciceCaps() etc... which are defined in gdi32.lib. ../lib/librtmp.a(rtmp.o):rtmp.c:(.text+0x1b3b): undefined reference to `inet_addr@4' ../lib/librtmp.a(rtmp.o):rtmp.c:(.text+0x1ba4): undefined reference to `inet_addr@4' ../lib/librtmp.a(rtmp.o):rtmp.c:(.text+0x5d1e): undefined reference to `htonl@4' ../lib/librtmp.a(rtmp.o):rtmp.c:(.text+0x5eed): undefined reference to `ntohl@4' These are defined in ws2_32.lib. What libraries is your application linking against? I'm not a MinGW / Eclipse user but it looks like you will need to add gdi32.lib and ws2_32.lib to your project.

Hiya, ws2_32.lib was already linked, I added gdi32.lib. Errors decreased. The following remain ../lib/librtmp.a(rtmp.o):rtmp.c:(.text+0x1b3b): undefined reference to `inet_addr@4' ../lib/librtmp.a(rtmp.o):rtmp.c:(.text+0x732c): undefined reference to `htonl@4' ../lib/librtmp.a(rtmp.o):rtmp.c:(.text+0x757f): undefined reference to `ntohl@4' Interesting. These are definitely in ws2_32.lib. ../lib/librtmp.a(rtmp.o):rtmp.c:(.text+0xb45): undefined reference to `timeGetTime@0' I just had to check MSDN for this one - and it says this function is defined in winmm.lib. I'm not too familiar with librtmp, so I just downloaded the source for it and checked out it's makefile which includes the following when building with mingw: -lws2_32 -lwinmm -lgdi32 Can you add -winmm and see if that decreases the number of errors by 1? If not, then there is something else going wrong (as the unresolved externals for ws2_32 have got me baffled at the minute)!
