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 --prefix=/R/winlibs64-10.3.0/inst_gcc-offload-amdgcn-10.3.0/share/gcc --build=x86_64-w64-mingw32 --host=x86_64-w64-mingw32 --target=amdgcn-amdhsa --enable-as-accelerator-for=x86_64-w64-mingw32 --with-build-time-tools=/d/Prog/winlibs64-10.3.0/custombuilt/share/amdgcn-tools/amdgcn-amdhsa/bin --with-gnu-as --with-gnu-ld --disable-serial-configure --enable-checking=release --without-libbacktrace --without-included-gettext --without-cuda-driver --enable-multiarch --enable-newlib-io-long-long --enable-linker-build-id --with-newlib --disable-sjlj-exceptions --disable-libunwind-exceptions --disable-libgomp --enable-languages=c,c++,lto,objc,obj-c++,d CFLAGS="-I/d/Prog/winlibs64-10.3.0/custombuilt/include/mman-win32" LDFLAGS="-Wl,--as-needed -lmman" ^ permalink raw reply [flat|nested] 4+ messages in thread

As mentioned in https://gcc.gnu.org/wiki/Offloading#For_AMD_GCN: do you have LLVM available to do as/ld for GCN? /winlibs64-10.3.0/gcc-offload-amdgcn-10.3.0/gcc-10.3.0/build_win_offload-amdgcn/gcc/as: line 106: exec: -t: invalid option ^ permalink raw reply [flat|nested] 4+ messages in thread

What options are needed to tell configure where to look for the assembler and linker? ^ permalink raw reply [flat|nested] 4+ messages in thread
