Error building Sage (gcc-4.9.2.p1)

[Tynan Kelly]

Hi,

I'm not a developer (at least not an expert!) and I'm having trouble building Sage from source. I get an error saying the following package(s) may have failed to build:

package: gcc-4.9.2.p1

I'm running OS X 10.10.3 and Xcode 6.3.1. I have tried building twice today, first using Sage 6.6, and then 6.5, both resulting in the exact same error. The log is too large to post, so I've pasted the last little bit with the error directly here.

Comparing stages 2 and 3

Please email sage-devel (http://groups.google.com/group/sage-devel)

explaining the problem and including the relevant part of the log file

  /Applications/sage-6.5/logs/pkgs/gcc-4.9.2.p1.log

Describe your computer, operating system, etc.

If you want to try to fix the problem yourself, *don't* just cd to

/Applications/sage-6.5/local/var/tmp/sage/build/gcc-4.9.2.p1 and type 'make' or whatever is appropriate.

Instead, the following commands setup all environment variables

correctly and load a subshell for you to debug the error:

  (cd '/Applications/sage-6.5/local/var/tmp/sage/build/gcc-4.9.2.p1' && '/Applications/sage-6.5/sage' --sh)

When you are done debugging, you can type "exit" to leave the subshell.

Please help!

Thank you!

I am afraid you'll need to get 6.7.beta3 to get the needed fix
to build gcc with xcode 6.3.1.

That fix [1] is not even in Sage 6.7.beta3.

The following /should/^TM work though:

export GCC_CONFIGURE="--with-build-config=bootstrap-debug"

make


No guarantees; you may run into further problems...

I thought it was in. Anyway it worked for me but as Leif said
there may be further problems. Probably not in gcc though.
