It wasn't that straight-forward for me to find information about this "common case" as you call it ;-) . I initially had problems finding the -B option of clang (it is not listed in --help nor in --help-hidden). The --gcc-toolchain-argument does not work with the clang I built: ../../upstream/build/bin/clang++ --gcc-toolchain clang-3.8: error: unsupported option '--gcc-toolchain' clang-3.8: error: no input files But it is listed in --help. Is this a bug or is my build faulty? I tried --sysroot and it made the path appear in the clang-system-include-paths. But my gcc-toolchain does not have the c++-headers in there just the C ones. C++ header files were installed to path/to/toolchain/<tuple>/include/c++/<gcc-version> I generated my gcc-toolchain with crosstool-ng. I haven't found yet the option (if any) to tell ct-ng to install c++-headers in sysroot as well. Thank you for your input. regards, -- Patrick. _______________________________________________ cfe-users mailing list cfe-users@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users
