[Module TS] Help


I put together a small test but it doesn’t work and I didn’t find much documentation so maybe someone can help?

  1. std.cppm
    export module std;

  2. cmd.cppm
    export module cmd;
    import std;
    namespace cmd {
    export enum struct value_type : std::uint8_t {
    INT = 0


but the compilation of cmd module fails:

/usr/local/opt/llvm/bin/clang -x c+±module -Og -g -fno-omit-frame-pointer -std=c++1z -fmodules-ts -nostdinc++ -isystem /usr/local/opt/llvm
/include/c++/v1 -Weverything -Wno-c++98-compat -Wno-c++98-compat-pedantic -Wno-c++11-compat -Wno-c++11-compat-pedantic -Wno-padded -Wno-documentation-unknown-command -Wno-documentation --precompile -fmodule-file=std.pcm -o cmd.pcm cmd.cppm
cmd.cppm:8:37: error: use of undeclared identifier ‘std’
export enum struct value_type : std::uint8_t

Any ideas why? Any suggestions to make it work?

PS: clang version
clang version 5.0.0 (https://llvm.org/git/clang.git 2004a0d58e49a79917f4fe861462f3dd59d42009) (https://llvm.org/git/llvm.git a4a73ad242dce894dbb05b9871d5ba133149f0d4)
Target: x86_64-apple-darwin16.6.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm/bin



This question is probably a better fit for the cfe-users / dev mailing list since it is about the clang frontend.
