[sage-support] Re: Building SageMath 6.8: gf2x, ncurses error in ArchLinux
I have compiled the sage 6.8 source code twice. Just wanted to add that the two proposed solutions from above work.

[sage-support] Re: Building SageMath 6.8: gf2x, ncurses error in ArchLinux
Hello Paul, Unfortunately I don't have access to GCC 4.9.x. I think after Volker's suggestion GCC 4.9.2 was supposed to be built, but it failed. I did try to build the source you suggested using GCC 5.2.0 and it failed again. Please find attached the compilation log (the error seems to be the same).

I looked at the log file. It seems the TC3 result is wrong up from degree 703. Please could you try to compile gf2x with a previous version of gcc (say 4.9.x), by running the following, and send us the corresponding log? You might also want to try again with GCC 5.2.0 to check the error is deterministic, and is independent from the Sage patches. $ wget https://gforge.inria.fr/frs/download.php/file/30873/gf2x-1.1.tar.gz $ tar xf gf2x-1.1.tar.gz $ cd gf2x-1.1 $ ./configure $ make $ make tune-lowlevel $ make tune-toom TOOM_TUNING_LIMIT=100 Best regards, Paul Zimmermann -- Sent from my massive iPhone 6 plus. -- William (http://wstein.org) -- You received this message because you are subscribed to the Google Groups sage-support group.

These seem to be known issues with gcc version = 5, see [1] and [2]. A possible workaround is to use the attached patch (adapted to fix the issue for gcc 5.2.0).

Shipping with GCC 5.2.0 is probably a bit too risky on the Arch side... Can you try make distclean SAGE_INSTALL_GCC=yes make On Monday, July 27, 2015 at 7:43:54 PM UTC+2, fidelbc wrote: Hello, I'm trying to build sage on arch linux: $ uname -a Linux 4.1.2-2-ARCH #1 SMP PREEMPT Wed Jul 15 08:30:32 UTC 2015 x86_64 GNU/Linux The packages that seem to fail to build are gf2x and ncurses (please see attached logs).
