Gorm don't work

[Germán Arias]

Hi,

After some years I'm working in a new release of FisicaLab, but I can't
work with gorm files since Gorm is unusable. I'm using all the code
from Github with GCC. I get things like:

2019-01-22 16:01:36.797 Gorm[5259:5259] Target <GormInspectorsManager:
0x15f50d0> does not respont to action _popUpItemAction:
2019-01-22 16:01:48.065 Gorm[5259:5259] GormDocument.m:109  Assertion
failed in GormDocument(instance), method _docWindow.  Unable to find
_window ivar in NSDocument class
2019-01-22 16:01:48.065 Gorm[5259:5259] Exception occurred while
loading model: GormDocument.m:109  Assertion failed in
GormDocument(instance), method _docWindow.  Unable to find _window ivar
in NSDocument class
2019-01-22 16:01:48.066 Gorm[5259:5259] Failed to load Gorm
2019-01-22 16:01:48.066 Gorm[5259:5259] NSWindowController: could not
load nib named GormDocument.nib

Any suggestion?
