Dear subscribers,
I admit that I am not an expert in using gcc/ld and especially their flags.
Anyway I used them from time time and I know how to compile basic c codes.
I always developed in 32-bit world (x86) and I have never had issues.
I recently passed to a new system which has Win7 and 64-bit and I am trying to
compile wxWidgets-3.0 to make a pure 32-bit bin library (so working on 32-bit
systems and 64-bit).
Besides the flags that are package-specific, I'd like to exchange some opinion
about the flags I am using to try to get the package compiled and linked.
TDM-GCC 4.8.1 claims to compile either for x64 or x86 architecture.
So this is the way I start the make.
make -f makefile.gcc <BUILD,MOOLITHIC and so on...>
CXXFLAGS="-fnoinline-functions -m32" CPPFLAGS="-m32 -march i686" CFLAGS="-m32
-march i686" LDFLAGS="-m32 -Ai686" RCFLAGS...
I get no errors or warnings during compilation.
The problem is that at the beginning of the linking phase I get
c:/tdm-gcc-64/bin/../lib/gcc/x86_64-w64-mingw32/4.8.1/../../../../x86_64-w64-mingw32/bin/ld.exe:
i386:x86-64 architecture of input file `gcc_mswuddll\monodll_version_rc.o' is
incompatible with i386 output
collect2.exe: error: ld returned 1 exit status
makefile.gcc:5202: recipe for target
'..\..\lib\gcc_dll\wxmsw30ud_gcc_custom.dll' failed
mingw32-make: *** [..\..\lib\gcc_dll\wxmsw30ud_gcc_custom.dll] Error 1
I really cannot get the point why monodll_version_rc.o was compiled for x86-64
and how to force it to have i386/i686.
Thanks in advance for your help.
