Troubleshooting common problems¶

`savepath`¶

Sometimes when executing savepath in Ubuntu the following warning appears:

Warning: Unable to save path to file '/usr/local/MATLAB/R2019b/toolbox/local/pathdef.m'. You can save your path to a different
location by calling SAVEPATH with an input argument that specifies the full path. For MATLAB to use that path in future
sessions, save the path to 'pathdef.m' in your MATLAB startup folder.

This can be fixed by running:

sudo chown $USER /usr/local/MATLAB/R2019b/toolbox/local/pathdef.m

Calling GridLAB-D from MATLAB¶

Sometimes when calling GridLAB-D from MATLAB, the following error appears:

ERROR    [INIT] : gldcore/module.c(426): module 'powerflow' load failed - /usr/local/MATLAB/R2017b/sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /home/ubuntu/lib/gridlabd/powerflow.so)

To fix this problem, execute the following in a terminal:

cd /usr/local/MATLAB/R2019b/sys/os/glnxa64

sudo mv libstdc++.so.6 libstdc++.so.6.old

Sphinx documentation issues¶

Sphinx aliases (e.g., longtext| replace:: this is a very very long text to include) do not work when documenting keyword arguments in MATLAB code files
