Description Michael Cronenworth 2018-09-17 15:52:41 UTC

Description of problem:
Wine 3.0.3 (and 3.8) introduced a change[1] to require the '__builtin_ms_va_list' extension and when it is missing wine will compile with clang. Clang 5.0 or higher is required for this extension and RHEL 7 ships Clang 3. Wine no longer compiles on aarch64 and RHEL 7.

Version-Release number of selected component (if applicable):
gcc-4.8.5-28.el7_5.1.x86_64


This has also been reported with upstream.

Comment 3 Marek Polacek 2018-09-17 17:42:57 UTC

This doesn't seem like something that I think we would add to the system RHEL 7 compiler.  If this is implemented upstream, it would eventually end up in gcc from the Red Hat Developer Toolset.  Moving it there thus.

Comment 5 Michael Cronenworth 2018-09-17 17:52:01 UTC

FYI: This doesn't help build Wine in EPEL[1], which is where it is packaged and I am the maintainer. I will have to drop the aarch64 build based on your reply. Thanks.

Comment 6 Marek Polacek 2019-07-09 19:52:20 UTC

No progress on the upstream PR.  Won't be in DTS 9 thus.

Comment 7 Marek Polacek 2020-12-09 21:32:08 UTC

This bug is getting stale and we don't expect this issue will be resolved in the next DTS, therefore closing.  Let's track it in the upstream PR.
