FYI these are the linker errors after building Clang with this patch added also: > lld-link: error: undefined symbol: __CxxFrameHandler3 > >>> referenced by obj/libgnustep-base.obj/GSHTTPAuthentication.m.o:(.xdata) > >>> referenced by obj/libgnustep-base.obj/GSHTTPAuthentication.m.o:(.xdata) > >>> referenced by > >>> obj/libgnustep-base.obj/GSHTTPAuthentication.m.o:($ip2state$_c_GSHTTPAuthentication__authenticationWithCredential_inProtectionSpace_) > >>> referenced 258 more times > > lld-link: error: undefined symbol: vtable for __cxxabiv1::__class_type_info > >>> referenced by obj/libgnustep-base.obj/GSHTTPAuthentication.m.o:(typeinfo > >>> for NSObject) > >>> referenced by obj/libgnustep-base.obj/GSTimSort.m.o > >>> referenced by obj/libgnustep-base.obj/GSTLS.m.o > > lld-link: error: undefined symbol: vtable for __cxxabiv1::__si_class_type_info > >>> referenced by obj/libgnustep-base.obj/GSHTTPAuthentication.m.o:(typeinfo > >>> for NSException) > >>> referenced by obj/libgnustep-base.obj/GSTimSort.m.o > >>> referenced by obj/libgnustep-base.obj/GSTLS.m.o > > lld-link: error: undefined symbol: vtable for __cxxabiv1::__pointer_type_info > >>> referenced by obj/libgnustep-base.obj/GSHTTPAuthentication.m.o:(typeinfo > >>> for NSException*) > >>> referenced by obj/libgnustep-base.obj/GSTimSort.m.o > >>> referenced by obj/libgnustep-base.obj/GSTLS.m.o For now I might try disabling native exceptions (which looks like will require some changes in Make as it assumes libobjc2 supports them) to keep moving towards a Clang build of GNUstep on Windows. That being said, it would be great to get a better idea of what needs to be done to get exception handling working with MinGW (in Clang and/or libobjc2). We’d be happy to support or sponsor required work in any way we can. In the meantime, if there’s anything else I can try so we can get a better picture just let me know. :) Thanks! Frederik
