amdgcn-amdhsa/libgcc/config.log
When I try to build the GCC amdgcn-amdhsa offload accelerator for MinGW-w64 for
both Windows 32-bit (--target=amdgcn-amdhsa
--enable-as-accelerator-for=i686-w64-mingw32) and 64-bit
(--target=amdgcn-amdhsa --enable-as-accelerator-for=x86_64-w64-mingw32).
This has been the case all versions I tried (last attempt was 10.3.0).
The output I get is:
checking for suffix of object files... configure: error: in
`/R/winlibs64-10.3.0/gcc-offload-amdgcn-10.3.0/gcc-10.3.0/build_win_offload-amdgcn/amdgcn-amdhsa/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See attached amdgcn-amdhsa/libgcc/config.log
The full command line (for Windows 64-bit) looks like this:
../configure
