External Library Error

layout: /usr/lib/libgdal.so: bind-file: $SNAP/usr/lib/libgdal.so
/usr/lib/libgdal.so.26: bind-file: $SNAP/usr/lib/libgdal.so.26
/usr/lib/libgdal.so.26.0.4: bind-file: $SNAP/usr/lib/libgdal.so.26.0.4

My app needs access to the GDAL library. When I use the above text in my yaml I get:

error while loading shared libraries: /snap/tdhogr/x9/usr/lib/libgdal.so.26: file too short

Any suggestion? Thanks

The file is likely malformed, as it seems to be a library compatibility symlink please check the link destination is correct (and fix it if it’s not)

Thanks for the reply. My app runs fine independent of snapcraft, so I believe the original files are ok. I suspect that snapcraft is somehow corrupting the symbolic link information. I have tried using: symlink: $SNAP/usr/lib/libgdal.so.26 but then the result is: cannot open shared object file: No such file or directory

you should really share your whole snapcraft.yaml and properly use three backticks ``` before and after pasted code …

did you add libgdal26 to your stage-packages: at all so it will show up at the desired path for the layout ?
