Julia does not build with gcc 5.0 development versions #10201
Comments
As mentioned here #10058 (comment) I'm pretty sure this is unique to |
I can't reproduce this on Ubuntu 14.04, even using shared-library system LLVM 3.5.0. What's the easiest way to reproduce the copr build environment, Docker container maybe? |
it's perhaps worth noting that llvm35 is not a supported configuration for release-0.3, and llvm36 support is still a work-in-progress on master (#9336) |
Yes but it appears to be what distributions (Debian, Fedora, probably others) are all using because LLVM 3.3 is no longer available in those repositories. |
Actually the same error started to appear on master builds today, and I also get it with 0.3.5. I think it may have to do with the introduction of gcc 5.0 in Fedora rawhide. Maybe it's not even related to LLVM 3.5. A new development version is coming soon, I'll check whether the failure is gone with it. I guess I should file a bug against Fedora/gcc -- except if you think Julia might be doing something wrong that the new gcc merely unveiled. |
Filed a bug in Fedora, let's see what they say: https://bugzilla.redhat.com/show_bug.cgi?id=1192930 |
Oh, right, I missed the |
I've tried adding But I may well have missed something. |
Hrm, maybe |
I think you nailed it. LLVM was built with gcc 4.9, and on Fedora rawhide (to be F23) |
The LLVM build fails on rawhide, so I cannot check. Let's say it works and leave the LLVM Fedora maintainers sort this out. Do you think adding |
We might end up needing it at some point after upgrading to LLVM 3.5, I'm not sure yet. |
OK, we'll see at that point then. |
Good news, Julia builds just fine now that LLVM has been rebuilt with |
I see this with current release-0.3 branch when building the Fedora package with LLVM 3.5. Looks like we need to backport one or several commits (master builds fine).
