with --profile, error: invalid argument '-std=c++11' not allowed with 'C'

[gaze]

Hey all, I have an lts-14.11 stack project that builds just fine when invoking stack build, but when building using stack build --profile, I get the following output

$ stack build --profile
inline-c-cpp-0.3.0.2: configure

This is under macOS 10.14.4. It's repeatable when deleting ~/.stack and/or .stack-work and then running build or build --profile in either order.

Thanks for the report. It looks like a clang-specific issue. However, I can't easily reproduce because of https://github.com/commercialhaskell/stack/issues/4073 . I might just try on the macbook later, but in the meantime, can you post a fully verbose build here? Maybe I can offer some guidance then.

Here's stack build --profile --verbose

dump.txt

[bitonic]

@gaze sadly that does not include the ghc invocation, and the invocation itself is not verbose. I think --verbose --cabal-verbose --ghc-options=-v should do it.

[gaze]

Apologies! Still a bit new to Haskell.

stack build --profile --verbose --cabal-verbose --ghc-options=-v 2> dump2.txt dump2.txt

[gaze]

Fwiw, this allowed me to build. Not sure what the interaction would be with other platforms

@gaze thank you, -optc-x-c++ makes a lot of sense, but I do not know why it'd break only with --profile. Anyway, I've created https://github.com/fpco/inline-c/pull/103 to fix this problem in the repo. It's a shame that even with those verbosity options we still do not see the cc invocation...

[bitonic]

@gaze I've added -x-c++ to inline-c-cpp.cabal, and uploaded new inline-c-cpp version 0.3.0.3.

seems this issue is back with ghc 8.10.3. has anybody else run into this again recently?
