I’m trying to create a snap package that uses a package called gdal-bin but I’m getting the following runtime error when I try to use one of the commands:
$ gdal-bin.ogr2ogr --help
ogr2ogr: error while loading shared libraries: libblas.so.3: cannot open shared object file: No such file or directory
Here is a snapcraft yaml that isn’t from my actual project but it isolates and reproduces my problem:
name: gdal-bin
base: core18 # the base snap is the execution environment for this snap
version: '0.1' # just for humans, typically '1.2+git' or '1.3.2'
summary: gdal-bin snap package
description: |
gdal-bin snap package
grade: devel # must be 'stable' to release into candidate/stable channels
confinement: devmode # use 'strict' once you have the right plugs and slots
parts:
gdal-bin:
plugin: nil
stage-packages:
- gdal-bin
apps:
ogr2ogr:
command: ogr2ogr
The program is trying to load the dependency from the following:
$ ldd /snap/geojobs/current/usr/bin/ogr2ogr
..
libblas.so.3 => /usr/lib/x86_64-linux-gnu/libblas.so.3 (0x00007f2067417000)
..
But it doesn’t exist there:
$ cd /snap/gdal-bin/current
$ sudo find . -name "*blas*"
./usr/lib/x86_64-linux-gnu/blas
./usr/lib/x86_64-linux-gnu/blas/libblas.so.3
./usr/lib/x86_64-linux-gnu/blas/libblas.so.3.7.1
./usr/share/doc/libblas3
The issue it seems is that the install seems to not have created a link to the library.
As a work around, I tried running ldconfig in an install hook script but that didn’t fix my issue. Changing my snapcraft yaml apps section to the following did fix my issue (NOTE: I also had the same problem with lapack):
...
apps:
ogr2ogr:
command: ogr2ogr
environment:
LD_LIBRARY_PATH: $LD_LIBRARY_PATH:$SNAP/usr/lib/x86_64-linux-gnu/blas:$SNAP/usr/lib/x86_64-linux-gnu/lapack
Why is the gdal-bin install faulty? Is there an issue on my side? Or is there a bug with snapcraft? Is there a more elegant way to work around this? Help please. Thank you!
