The problem seems to be that you need write access to the working directory when importing a combine archive - not sure if that is because of my code or libCombine, but tellurium does create temp files when importing.
The initial cwd for the kernel is /opt/Tellurium
, which is read-only, so can't import.
Hi Kyle,
I can run the example without problems on Ubuntu 16.04 via Import -> Import Archive
Also executing the archive directly works te.executeCombineArchive("/home/mkoenig/Desktop/ca-export.omex");
I don't have write access as user to /opt/Tellurium
so not sure what is going on there.
Normally the files should be created in the system tmp directory (this is where the archives are extracted to work with them), so probably the permissions to the tmp
directory are incorrect on the machine.
My permissions on /tmp are
drwxrwxrwt 19 root root 450560 Nov 10 08:56 .
i.e. everybody can read, write, execute in the tmp dir. Check if this is the same on the system. Best M
Thanks for testing this in your setup. I still have the problem where the extractEntryToString
function in libCombine only works if the user has read/write access to the cwd, as shown in the attached notebook. It would be easy enough to fix in Tellurium by simply changing the cwd to /tmp before importing an archive, then changing back again.
I was doing some testing on my Debian 8 VM and I noticed that extractEntryToString only works when the archive is in the cwd. Anyone else run into this? It only seems to occur on this specific version of Linux.
@matthiaskoenig, since you're running Ubuntu, I was wondering if you are able to import the attached COMBINE archive using
Import
->Import Combine Archive (OMEX)...
from the cell creator bar in the notebook (latest ver 2.0.8). Please let me know if it fails or not.Attached archive (can rename to .omex or keep as-is): ca-export.zip
