Hi guys,
I'm lost in trying to fix the Edgar module to run again in E. Since some
months the python import machinery does not work anymore and the edgar
module is not able anymore to import the python efl bindings.
Nothing has changed in Edgar nor in python-efl and I'm able to correctly
use the machinery in a simple test app (attached), it just does not work
when used inside an E module. I suspect something related to the new meson
build, but not sure at all.
The simple test attached can be built as:
gcc -o test_py test_py.c `python-config --cflags --libs --embed`
`pkg-config --libs --cflags efl-ui`
when run it print OK, that means the python-efl module has been found and
linked. While the same code in edgar fails on the import_efl__eo() call.
Note the test also need the attached .h file to build
To build/run this simple code of course python-efl must be installed
https://phab.enlightenment.org/w/projects/python_bindings_for_efl/
The edgar module instead is documented here:
https://phab.enlightenment.org/w/emodules/edgar/
Any help/ideas would be appreciated as I really don't have any idea atm
The same issue has been recently raised also on the e-user mailing list
Thanks
