Description

This was on [sage-devel] (2009-01-08):

RuntimeError?: While attempting to compile /usr/local/sage-3.2.3/data/ extcodemagma/latex/latex.m (Data file non-existent): Can't open lock file /usr/local/sage-3.2.3/data/extcodemagma/latex/ latex.lck for writing (Permission denied)

While attempting to compile /usr/local/sage-3.2.3/data/extcodemagma/ sage/basic.m (Data file non-existent): Can't open lock file /usr/local/sage-3.2.3/data/extcodemagma/sage/ basic.lck for writing (Permission denied

It seems like you need write access to extcode (see above) at least for the first time you're running Magma from Sage. IIRC there was some talk about lifting this requirement somehow.

The only idea I have to deal with this is to copy all of extcode/magma into .sage/extcode/magma say, and then have sage only use magma code that's in .sage/extcode/magma/. Whenever sage is upgraded, the .sage/extcode/magma would have to get deleted and re-copied, using a facility similar to how the Gap workspace always gets updated when Sage has been upgraded.
