[Insight-developers] Compiling a 32bits app using ITK in a 64bits linux environment (gcc)

[Benoit Scherrer]

Thanks for the answer!

yes i even deleted everything (all build/install folders) twice  and re-run
cmake (not ccmake / cmake-gui) with

-DCMAKE_CXX_FLAGS:STRING=-m32 -DCMAKE_C_FLAGS:STRING=-m32
-DCMAKE_EXE_LINKER_FLAGS:STRING=-m32
-DCMAKE_REQUIRED_FLAGS:STRING=-m32


directly in the command line (so for the first CMake config)

Rq: ITK *do* compile so it has the correct configuration
then, my application includes itkIndex.h which includes itkMath.h which
includes itkMathDetail.h
and it refuses to compile.

RQ: the x86_64 compile without any trouble.
Maybe i missed the installation of some x86 (i686) developer package?
