compiling FreeImage

[sonoro1234]

Hi,

Downloaded tdm64-gcc-9.2.0.exe and installed. Trying to compile FreeImage I am getting this error

[  0%] Building CXX object CMakeFiles/FreeImage.dir/Source/FreeImage/FreeImage.cpp.obj
In file included from C:/TDM-GCC-64/x86_64-w64-mingw32/include/windows.h:9,
                 from C:\LuaGL\gitsources\FreeImageORIG\Source\FreeImage\FreeImage.cpp:28:

 you mean '__mingw_wcstof'?

      |                             ^~~~~~~~

Is there something I can do to solve it?

Thanks Victor Bombi

• Can you build with make V=1 and post the command line used?
• Can you add -save-temps to the FreeImage.cpp command line and attach the resulting FreeImage.i file to this issue?
• Is __cplusplus defined?

[sonoro1234]

with mingw32-make VERBOSE=1 the command line shown is

C:\TDM-GCC-64\bin\g++.exe  -DDISABLE_PERF_MEASUREMENT -DFreeImage_EXPORTS -DNO_LCMS -DOPJ_STATIC -DWINVER=0x0500 -D__ANSI__ @CMakeFiles/FreeImage.dir/includes_CXX.rsp -O2 -g -DNDEBUG   -std=gnu++98 -o CMakeFiles\FreeImage.dir\Source\FreeImage\FreeImage.cpp.obj -c C:\LuaGL\gitsources\FreeImageORIG\Source\FreeImage\FreeImage.cpp

adding -save-temps to the command line FreeImage.ii is generated (.txt added for uploading)

FreeImage.ii.txt

* Is `__cplusplus` defined?

I cant be sure, but I guess it is, because a cpp file is compiled by g++.exe?

I have tried with just released tdm-gcc I have checked that __cplusplus is defined modifying the source with

#if defined(__cplusplus)
#warning "__cplusplus is defined"
#else
#warning "__cplusplus is NOT defined"
#endif
