The makecontext() routines are now in glibc 2.16 and Ubuntu Precise eglibc 2.15.

[Bug 937011] Re: configure test lin libgo fails on arm (setcontext)
Thank you for the bug report. The comments above clarifies that the problem is that the functions getcontext and setcontext is not supported for ARM. I've set this ticket to medium priority for now. As stated by Peter above, getting the functions into eglibc has already been recognized as a todo, but not with highest priority. ** Changed in: gcc-linaro Importance: Undecided = Medium ** Changed in: gcc-linaro Status: New = Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/937011 Title: configure test lin libgo fails on arm (setcontext) To manage notifications about this bug go to: https://bugs.launchpad.net/gcc/+bug/937011/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

IIRC the setcontext co API is not implemented on ARM/Linux.

Specifically the functions exist but return ENOSYS, which is why this: if (getcontext (c) 0) abort (); will abort. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/937011 Title: configure test lin libgo fails on arm (setcontext) To manage notifications about this bug go to: https://bugs.launchpad.net/gcc/+bug/937011/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 937011] Re: configure test lin libgo fails on arm (setcontext)
Trying to get these functions into eglibc for ARM is kind of on the toolchain group's todo list, but (a) not at a hugely high priority and (b) it will take a little while for them to percolate through eglibc and back into distros anyway, so apps/configure scripts need to be prepared to handle the returns-ENOSYS case anyway. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/937011 Title: configure test lin libgo fails on arm (setcontext) To manage notifications about this bug go to: https://bugs.launchpad.net/gcc/+bug/937011/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
