It is working for me. Following modifications were also required for the compile.sh and compile-amd.sh. Assuming name of your fat archive is **libmylib.a** and it is present in the **current directory**, the command to use it will be as follows: > clang++ -fopenmp -fopenmp-targets=nvptx64 main.cpp **-L. -lmylib** or > clang++ -fopenmp -fopenmp-targets=amdgcn-amd-amdhsa > -Xopenmp-target=amdgcn-amd-amdhsa -march=gfx906 main.cpp** -L. -lmylib** So, compile.sh should be: > clang++ -fopenmp -fopenmp-targets=nvptx64 -c -Xopenmp-target=nvptx64 > -march=sm_50 classA.cpp > rm -f libmylib.a > ar qc libmylib.a classA.o > ranlib libmylib.a > clang++ -fopenmp -fopenmp-targets=nvptx64 main.cpp **-L. -lmylib** > ./a.out And compile-amd.sh should be: > clang++ -fopenmp -fopenmp-targets=amdgcn-amd-amdhsa > -Xopenmp-target=amdgcn-amd-amdhsa -march=gfx906 -c classA.cpp > rm -f libmylib.a > llvm-ar qc libmylib.a classA.o > llvm-ranlib libmylib.a > clang++ -fopenmp -fopenmp-targets=amdgcn-amd-amdhsa > -Xopenmp-target=amdgcn-amd-amdhsa -march=gfx906 main.cpp **-L. -lmylib** > ./a.out Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D105191/new/ https://reviews.llvm.org/D105191 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
