closes #225

[dpo]

Doesn't work out of the box on macOS unfortunately, even after setting DYLD_FALLBACK_LIBRARY_PATH:

The updated version works for me on macOS.

@abelsiqueira Does it work for you on Linux?

[dpo]

There's still a caveat that running runcutest tries to update the CUTEst library, which results in a lot of "permission denied" messages being printed. It's inconsequential, but annoying.

[abelsiqueira]

Unfortunately doesn't work for me either:

/home/abel/.julia/artifacts/c990de2425d3a17849e2f6bbe47decf0f81036d8/libexec/SIFDecode-2.0.3/objects/pc64.lnx.gfo/double/run_sifdecode: error while loading shared libraries: libgfortran.so.4: cannot open shared object file: No such file or directory

[dpo]

Does it work if you define this bash function: https://github.com/JuliaSmoothOptimizers/CUTEst.jl/pull/226/files#diff-4b9f14fdac93f5150aa5c070ec70fc63R129

[abelsiqueira]

Almost worked, needs a ; at the end: ... bash -c "..."; }. With that change, run_sifdecoder ROSENBR worked.

[dpo]

Should be good now.

[abelsiqueira]

We need a similar one for runcutest. I tried adding a

run_cutest() { ... source $CUTEST/bin/runcutest $*"; }

but it failed when I ran run_cutest -p genc -D ROSENBR with a bunch of these:

ar: /home/abel/packages/julias/julia-1.4-latest/bin/../lib/julia/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by /usr/lib/libLLVM-9.so)

The sifdecoder part ran correctly.

PS. The $* instead of $@ was necessary to parse the arguments correctly.

[dpo]

Does this work though

run_sifdecoder ROSENBR
run_cutest -p genc

[abelsiqueira]

No, it has the same error. The final line is Error opening file OUTSDIF.d., which I guess it's because the compilation failed.

[dpo]

Hm. It works for me on macOS. That seems to indicate an issue with the JLL... :-(

[dpo]

there are conflict markers in these changes.

[tmigot]

Thanks, I just noticed too. I rebased this just in case, if this is still of interest ?

[dpo]

It is, but what's a bit weird is that runcutest modifies the artifacts. It works, but it's not ideal. I should modify CUTEst itself so it only modifies files in ~/.cutest (say), and leaves the compiled object files alone.

[amontoison]

Can I close this PR? All the environment variables have been removed because they not needed anymore with the new artifact SIFDecode_jll.jl.
