Hi I'm working on updating the mingw toolchain for Fedora, and am building mingw-gcc-11 with mingw-crt-8.0.0. I'm stuck at this error when linking libgcc [1]: /usr/i686-w64-mingw32/bin/ld: _ctors_s.o:libgcc2.c:(.bss+0x0): multiple definition of `__DTOR_LIST__'; /usr/i686-w64-mingw32/sys-root/mingw/lib/../lib/dllcrt2.o:crtdll.c:(.dtors+0x0): first defined here /usr/i686-w64-mingw32/bin/ld: _ctors_s.o:libgcc2.c:(.bss+0x8): multiple definition of `__CTOR_LIST__'; /usr/i686-w64-mingw32/sys-root/mingw/lib/../lib/dllcrt2.o:crtdll.c:(.ctors+0x0): first defined here Indeed, I see mingw-w64-crt/crt/crtdll.c:__attribute__ (( __section__ (".dtors"), __used__ , aligned(sizeof(void *)))) const void * __DTOR_LIST__ = (void *) -1; mingw-w64-crt/crt/crtdll.c:__attribute__ (( __section__ (".ctors"), __used__ , aligned(sizeof(void *)))) const void * __CTOR_LIST__ = (void *) -1; and libgcc/libgcc2.c:func_ptr __DTOR_LIST__[2] = {0, 0}; libgcc/libgcc2.c:func_ptr __CTOR_LIST__[2] = {0, 0}; Any hints are appreciated!
