OMP Permission error

argosopentech · January 23, 2022, 11:39am

I build a new version of my snap argos-translate, which works locally when installed with --devmode but breaks with this error when installed from the snap store. Any suggestions?

OMP: Error #179: Function Can't open SHM2 failed:
OMP: System error #13: Permission denied

install the snappy-debug snap and run it in a second terminal while starting your app … it might/should give some suggestions (if there are solutions via adding an interface etc)

This is what I get from snappy-debug, I’m going to try adding the suggested plugs and re-uploading.
