Bug#931223: sagemath: sage test fails to test sagetex example_doctest.sage generated from sagetex example.tex

[Tobias Hansen]

Hi,

yes, to run doctests one needs to set SAGE_SRC and SAGE_PKGS. From sagemath's README.Debian:

One can run the tests using the installed sage packages. First, get the source
code for this package (`apt-get source sagemath`), and make sure the Debian
patches are applied. Then, from the 'sage' directory in the sources:

 *$ export -n SAGE_LOCAL SAGE_ROOT
 *$ SAGE_SRC=$(pwd)/src SAGE_PKGS=$(pwd)/build/pkgs sage -t -p --long --logfile=ptestlong.log --all

Hopefully we can refactor and simplify the package one day and then also doctesting should hopefully work out of the box.

What you are trying is slightly different but it boils down to patching sage to do doctests without having SAGE_PKGS around.

Best,
Tobias
