Description Milan Bouchet-Valat 2016-01-28 17:33:05 UTC

This morning, I was able to successfully build the Julia package in rawhide:
https://kojipkgs.fedoraproject.org//packages/julia/0.4.3/1.fc24/data/logs/x86_64/

But now, I get compilation errors (with the very same code):
> /usr/include/c++/6.0.0/cmath:615:11: error: '::isinf' has not been declared
>    using ::isinf;
>            ^~~~~
> /usr/include/c++/6.0.0/cmath:640:11: error: '::isnan' has not been declared
>    using ::isnan;
           ^~~~~

The only packages which have been updated in the meantime are glibc, openssl-libs and gosrpm-macros. I strongly suspect glibc for obvious reasons, but in particular because isinf and isnan in cmath from libstdc++-devel interact with cmath.h from glibc. It looks like we need a more recent version of gcc, or a patch from upstream, to make them work together:
https://gcc.gnu.org/ml/libstdc++/2016-01/msg00023.html

Comment 1 Jonathan Wakely 2016-01-28 17:43:22 UTC

If glibc has been updated then it looks like gcc needs to be rebuilt in rawhide, see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69413#c2

Comment 2 Florian Weimer 2016-01-28 18:29:08 UTC

I untagged the glibc build for now.

Comment 3 Milan Bouchet-Valat 2016-01-28 20:41:46 UTC

Thanks, that indeed fixed the problem.

Comment 4 Florian Weimer 2016-01-28 21:03:50 UTC

I've re-tagged it, in preparation for a gcc build which needs the new glibc.

Comment 5 Florian Weimer 2016-01-28 22:02:34 UTC

Untagged again, GCC build is still running: http://koji.fedoraproject.org/koji/taskinfo?taskID=12715698

Comment 6 Florian Weimer 2016-02-05 11:56:46 UTC

Fixed in rawhide.

Comment 7 Milan Bouchet-Valat 2016-02-05 13:04:22 UTC

I can confirm the Julia build went fine in rawhide with glibc 2.22.90-32.fc24.
