Description Pavel Roskin 2018-01-13 03:02:14 UTC
Description of problem:

clang-5.0.0-1.fc27 provides clang-5.0 and clang++ but not clang++-5.0

Version-Release number of selected component (if applicable):

clang-5.0.0-1.fc27

How reproducible:

Every time

Steps to Reproduce:
1. run clang++-5.0

Actual results:
bash: clang++-5.0: command not found...

Expected results:
clang++-5.0: error: no input files

Additional info:

It it inconsistent to provide a C compiler called clang-5.0 but not a C++ compiler called clang++-5.0.

Having a versioned name for the compiler is convenient. It can be used to distinguish one compiler from another.

Comment 3 Pavel Roskin 2018-03-26 21:32:44 UTC
Thank you for the fix. It works for me. I'm a bit surprised that clang++-5.0 is a link to clang++ rather than the other way around (clang is a link to clang-5.0).

I think the most robust link order would be

clang -> clang-5.0
clang++ -> clang++-5.0
clang++-5.0 -> clang-5.0

That's probably not a big deal in the contest of a distro that provides a single clang version. But the upstream would likely do it differently.

There is an upstream issue:

I agree that logically this would make more sense, but implementing it this way in Fedora would require patching the LLVM sources, which I'm hesitant to do for a user convenience feature like this one.  Ideally this change would come from upstream.
