--- Comment #3 from ghjghj530-bubu at yahoo dot de --- Changed my testcode to int main(). The error stil occurs. The system is Windows 7, 64 bit, mingw. Is use the GCC in a company-specific enviroment with some customized linkersripts. We first compile the source file with: i686-elf-gcc.exe -c C:\temp\2\Main.cpp -o c:\temp\2\Main.cpp.o -D_GLIBCXX_USE_CXX11_ABI=0 and then call the linker: i686-elf-gcc.exe C:\Temp\2\Main.cpp.o -o C:\Temp\2\a.out -Wl,-lstdc++,-lsupc++,-lm -lc (i have removed a -specs paramter and some target plattform specific parameters). I'm sorry for the incomplete command line. I still hope the *.a-File analysis from my original post can help you.
