pkgconfig errors during build on Ubuntu 22.04

[sr99622]

During gegl build, this error was encountered

[859/1263] Generating gegl/Gegl-0.4.gir with a custom command
Package babl-0.1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `babl-0.1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'babl-0.1' found

The file /usr/local/lib/x86_64-linux-gnu/pkgconfig/babl.pc was renamed to babl-0.1.pc and then gegl build success

Then during gimp build

meson.build:366:0: ERROR: Could not generate cargs for gegl-0.4:
Package babl was not found in the pkg-config search path.
Perhaps you should add the directory containing `babl.pc'
to the PKG_CONFIG_PATH environment variable
Package 'babl', required by 'gegl-0.4', not found

File above was changed back to babl.pc and gimp build success, and then open vino extensions were found in layers. There were some other instances of the babl-0.1.pc not found, but they didn't seem to affect the build ?

Edit: Tried re-building with symlink babl-0.1.pc to babl.pc and compiled without the same error. There was this error however after gimp install

Added the path as shown in gimp. There are three selections in the openvino ai plugins menu option, semantic segmentation, stable diffusion and superresolution. Stable Diffusion and semantic segmentation seem to be working but superresolution fails with error

Tried testing a few stable diffusion models, during one of these (some control-...) the system froze and had to power down to re-boot. Then when re-starting gimp a bunch of error messages in the terminal, and stable diffusion would not start with error

Plug-in crashed: "stable-diffusion-ov.py"

The dying plug-in may have messed up GIMP's internal state. You may want to save your images and restart GIMP to be on the safe side.

For reference the CPU is an Intel i5-12400, GPU A380, 16 GB RAM, stable diffusion not coming back after re-boot

Hi @sr99622 - looks like there is some permission issue with /home/stephen directory. Can you check that you have write permissions? Looks like the installation failed and directory creation failed.
