Re: [Gwyddion-users] Python error when trying to build from source with pygwy support

OK, I think it’s working now! I assumed that pygtk2 was installed since I was able to access the Pygwy Console, but I looked and saw that neither `sudo dnf install gwyddion.x86_64` nor `sudo dnf install gwyddion-devel.x86_64`installed it. Following `sudo dnf install pygtk2.x86_64`, the Pygwy Console appears to be working (no errors from `import gwyutils` or `d = gwy.gwy_app_data_browser_get_current(gwy.APP_DATA_FIELD)`). A standalone Pygwy script consisting only of…

#!/usr/bin/python2
import gwy
print(gwy.__file__)

…also seems to work, although I do get a message from gtk; the output is…

Gtk-Message: 16:54:06.966: Failed to load module "pk-gtk-module"
/usr/lib64/python2.7/site-packages/gwy.so

…but if the pk-gtk-module thing isn’t important, then I think we are up and running. Thank you so much!

You do not need to do ‘import gwy’ in the console because it's
automatically there. However, if you run it, it should still work. I
have just tested the F40 packages and it works fine for me.

For standalone scripts you also need to install gwyddion-devel which
installs the standalone gwy module (the one in the console is just
created on the fly there).

You may be running it under Python 3 (because that is the default) and
you do not have gwyddion-devel.

However, I do not understand the console problem.
