Clangd (Language Server) throws error for __integer_pack at pack.hpp about hpx

[andreichalapco]

On further checking the cmake building process I discovered this:

  # Check the availability of certain C++ builtins
  hpx_check_for_builtin_integer_pack(DEFINITIONS HPX_HAVE_BUILTIN_INTEGER_PACK)

  hpx_check_for_builtin_make_integer_seq(
    DEFINITIONS HPX_HAVE_BUILTIN_MAKE_INTEGER_SEQ
  )

So basically if building the source with clang ... I can avoid the macro HPX_HAVE_BUILTIN_INTEGER_PACK ... and have HPX_HAVE_BUILTIN_MAKE_INTEGER_SEQ.

I still believe this is not something good ... because there are for sure many people that want to compile everything with gcc but still use the clangd language server ... (so basically use clion)

I'm not sure if anybody I know uses clangd for their work, so I wouldn't know whom to ask. This is probably caused by HPX being configured by one compiler (gcc) and being used with another one (clangd). The decision of what is supported is being made at configuration time, so that later on clangd sees things to be used that it doesn't support.

I'd very much appreciate it if you had the time and interest to come up with a possible fix (PR) for this.

I had reported that issue to jetbrains years ago.

So the issue is related to clangd (clion also uses this language server). I posted an issue and it was fixed in the newer versions of clang.
see clangd/clangd#1906.

Let's not close this issue. We've had similar reports in other contexts. I believe this can be fixed.

Yeah! I think you're right! As a feedback after using hpx there a lot of problems with the clangd lanaguge server, which is a real pity, because I think it is nowadays the most used one (it' s also open source). It would be nice if some efforts would be directed in this direction.

What other problems are there?
