Isis3: isis 4.2.0 installs wrong gsl version

[AndrewAnnex]

ISIS version(s) affected: 4.2.0

Description
it looks like following

the install instructions conda picks the wrong libgsl version, I had to manually install and saw it upgraded libgsl thusly: 2.2.1-blas_openblas_3 --> 2.6-h294904e_0

How to reproduce

conda create --name isis_4_2 python=3.6.0 -c defaults < I added the .0 and defaults were my addition, as I was running into issues there as well I decided to enforce some restrictions
conda activate isis_4_2
conda config --env --add channels conda-forge
conda config --env --add channels usgs-astrogeology
conda install -c usgs-astrogeology isis=4.2.0
python $CONDA_PREFIX/scripts/isis3VarInit.py < why is isisVarInt.py not available for 4.2.0?
qview > error about libgsl.so.25

Possible Solution

A suggested fix would be to add a CI test to the project using github actions to try installing various isis versions on a scheduled basis that may expose issues in conda land.

Additional context

here is the output for conda list after I installed gsl myself, maybe something obvious will poke out here, I also ran conda clean --all before running any of the above steps.

This doesn't address your primary issue, but, to answer a small question:

python $CONDA_PREFIX/scripts/isis3VarInit.py < why is isisVarInt.py not available for 4.2.0?

The PR that updated and renamed isis3VarInit.py to isisVarInt.py was merged after the new branch was created for the 4.2 RC (effectively a feature freeze.) Bug fixes that come in between the RC release and the official release are pulled into the release, but not new features.

Can you provide the exact error you got from qview? I wonder if this is a dependency of a dependency or a direct dependency problem.

[AndrewAnnex]

specific error is:
qview: error while loading shared libraries: libgsl.so.25: cannot open shared object file: No such file or directory

[AndrewAnnex]

if I run ldd on the qview executable it looks like the shared lib is not found

I got the same error and I just did conda update gsl after activating isis environment. It worked !

[AndrewAnnex]

I think the solution would be to pin a version for gsl and blas, or ensure that both blas and gsl are installed from the conda-forge
