Sage on Mac OS X 10.7

[Justin C. Walker]

I seem to be unable to build Sage on 10.7, so I'm checking my configuration against what you guys know to work.

I am running 10.7.1, with Xcode Version 4.2.1 (4D502). The beta4 release does not even get started for me (the prereq script objects to Xcode 4).

Thanks!!

I am running 10.7.1, with Xcode Version 4.2.1 (4D502).  The beta4 release does not even get started for me (the prereq script objects to Xcode 4).

There is a thread about building Sage in OS X 10.7 in sage-devel. One method which works for me, as reported there:

 - download http://sage.math.washington.edu/home/jdemeyer/release/sage-5.0.beta4-gcc/sage-5.0.beta4-gcc.tar rather than the usual beta4
 - upgrade to Xcode 4.3.
 - run Xcode, choose "Preferences" from the File menu, then choose the "Download" tab, and install the "Command Line Tools".
 - from the terminal, run "sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer".

(Another method, which seems to work on some machines but not others: just do the first step above and then do "export CC=clang" and "export CXX=clang++".)

Then "make ptestlong" should work.  If you do "export SAGE_CHECK=yes", cvxopt will fail self-tests, as will python (as usual), but everything else should work.

If you could follow up in the sage-devel thread, that might be best.

Following up as requested on this list:

Upgrading to Xcode 4.3 doesn't work for me: I am still on 10.7.1, and would prefer not to upgrade to 10.7.3 (which is required). Has anyone succeeded with my configuration (above)?

I've tried the 'CC=clang' trick, but that seems to run aground on the 'prereq' spkg-install check (if Xcode's version is 4.x or greater, complain and stop).

The complaint might have said "export the variable SAGE_PORT to something non-empty".  That's what you should do.

Justin,

It would be interesting to have more OS X 10.7 results. So, could you
please try:
$ SAGE_PORT=yes MAKE="make -j1" make

Then, in a separate directory a second Sage build with:
$ SAGE_PORT=yes CC=clang MAKE="make -j1" make

In all cases, success or not, please send me spkg/logs/gcc-4.6.2.log

[Justin C. Walker]

Both builds blew up in the build of MPIR.

I'm sending you a tarball containing the GCC and MPIR logs for each, direct to you.
