Static linking to SFML 2.0 libraries doesn't work

[Pfeffer]

I have a big project where I just moved from SFML 1.6 to 2.0. Dynamic linking worked fine until now. After changing to static linking I get this error:

src/input.o:input.cpp:(.text+0x1c): undefined reference to `_imp___ZN2sf6Window5closeEv'
src/input.o:input.cpp:(.text+0x1f3): undefined reference to `_imp___ZN2sf5Mouse11setPositionERKNS_7Vector2IiEERKNS_6WindowE'

Compiling is fine and I cleaned the project many times. I compiled the SFML 2.0 libraries by myself, with CMake and MinGW-GCC. The dynamic libraries worked fine. I have set BUILD_SHARED_LIBS = FALSE for compiling the static libs.

The result were this lib files (I only need this 3) which I added to the "lib" directory to my project:

• libsfml-window-s.a
• libsfml-system-s.a
• libsfml-graphics-s.a

I used the following command to link with MinGW-GCC 4.7.2:
g++  -DSFML_STATIC -Iinc -std=gnu++0x -O3 -fmessage-length=0 -DNDEBUG  -o bin/SFML-Prototype-Release.exe (object files) -Llib -Lbin -lsfml-graphics-s -lsfml-window-s -lsfml-system-s -lFreeImage  -lglew32 -lglu32 -lopengl32

And having files in "bin" directory:

• FreeImage.dll
• glew32.dll

And files in "lib" directory:

• libsfml-window-s.a
• libsfml-system-s.a
• libsfml-graphics-s.a
• FreeImage.lib

-DSFML_STATIC is a compiler flag (it defines a new macro), not a linker flag.

[Pfeffer]

Since it was an link error, I totally thought the problem was with the link command, but I had to add the -DSFML_STATIC flag to the compile command.

Tank you.
