Compiling 7.4.0 from CodeBlock project

Hello,

I'm trying to build V7.4.0 under Windows 10 with MinGW.

The codeblocks.bat  nicely opens  Code::Blocks  and compilation starts smoothly.

But after a while, I get this error :

g++.exe -mmmx -msse -msse2 -mfpmath=sse -std=gnu++0x -D_WIN32_WINNT=0x0501 -Wall -fexceptions -I -O2 -DNDEBUG -DNo_Exception -I..\..\..\inc -c C:\CAD-Tools\OpenCascade\src\Units\Units_UnitsLexicon.cxx -o ..\..\..\wnt\gcc\obj\src\Units\Units_UnitsLexicon.o

Could anybody help ?

Thanks
