R-devel fedora clang version #53

Open jangorecki opened 4 years ago

jangorecki commented 4 years ago

I noticed that R-devel fedora clang uses clang version 11.0.0 and rhub uses 10.0.1.

docker run -it rhub/fedora-clang-devel clang --version
#clang version 10.0.1 (Fedora 10.0.1-2.fc32)

Is it possible to align clang version to match CRAN's version?

cboettig commented 3 years ago

Looks like CRAN is now using clang-12, while the rhub gets clang-11 (the default clang currently shipped in the rolling debian:testing repos.) It looks like clang-12 can be found in the debian:sid repos, but it isn't the default version of clang there right now either (which is still on clang-11), so a simple apt-pinning strategy probably wouldn't work.

Maybe it would be possible to just install the current clang release from https://github.com/llvm/llvm-project/releases binaries? This might better keep in sync with CRAN's aggressive enforcement of testing against the latest released compiler versions instead of those shipped in linux distros...

There is an example of using recent clang in https://gitlab.com/jangorecki/dockerfiles/-/blob/r-devel/ubuntu-clang/Dockerfile And then reused this image in https://gitlab.com/jangorecki/dockerfiles/-/blob/r-devel/r-devel-clang/Dockerfile

I would expect it to work for clang-12 Note that it is not fedora but Ubuntu.

This has still been observed recently in #63 . I would vote to address this with priority, since it is impacting the reproducibility of CRAN failures on Fedora
