[sage-support] Re: error using simple solve example

2016-09-05 Thread Paul Masson 
Although you shouldn't have to, please try installing the OS X Command Line 
Tools for Xcode as described here:

http://doc.sagemath.org/html/en/installation/source.html#mac-os-x-prerequisite-installation

This error has appeared before 
 and 
installing these tools solved it. If that works for you, then please replay 
back so that I can start the process to fix the error again. Thanks!

FYI I run SageMath all the time on El Capitan, but I have the Command Line 
Tools installed so that I can compile from source code.

Thanks. I tried installing Maxima from sourceforge. This didn't help, 
although I don't know if would be expected to.

I'd be interested to know if anyone else is able to run Sage on OS X El 
Capitan. Might an older version work? Or is the Maxima problem independent 
of the Sage version? E.g. this page says "The binaries for SageMath 
6.10.beta7 will work":

Well, Sage is punting 'solve' to Maxima, and it looks like Maxima isn't
loaded correctly or something. SET-LOCALE-SUBDIR isn't anything
important, it's only setting the subdirectory for the on-line
documentation. One could delete that call, but I'm guessing one would
then run into a similar error with the next call to a Maxima function.

Sorry I can't be more helpful,
