[Cardoza2]

Note that SNOPT works just fine on julia 1.8.

[cibinjoseph]

This is due to the gfortran compiler version being used to compile Snopt under the hood. By default, Julia seems to use older 'stabler' gfortran versions when compiling. Installing a recent version of gfortran should ensure Snopt.jl works.
Gfortran versions 8.5 or above is required to compile snopt correctly.

To check which gfortran version is being used inside Julia, switch to the command line inside the REPL using ; and do

shell> gfortran --version
GNU Fortran (GCC) 13.2.0

On the BYU supercomputer, you can use module load gcc/latest or module load gcc/13 to get the right compiler.

Additionally, if you have intel compilers installed, Snopt.jl is set up to prefer those. If Snopt seems to not work even after gfortran is the right version, ensure that the ifort command does not work in the environment Julia is run from. This can be done temporarily by aliasing it to some other command like alias ifort="ls" or so.

[BTV25]

@cibinjoseph So why would this start causing a problem in Julia 1.10 but not in any other versions of Julia?

[cibinjoseph]

I'm not sure about that. Have you had the same issue on your system? I know the BYU supercomputer has RHEL7 which has gfortran 6 as the default. Or maybe Julia 1.10 comes with gfortran v4 or they reverted to it.

[BTV25]

Yes. Same issue on my system and same in Adam's. Maybe this is something to send as feedback to Julia 1.10

[cibinjoseph]

Wait, does it still not work when switching to a newer compiler?

[BTV25]

I haven't tried yet, but I'm wondering if this whole issue indicates a flaw in Julia 1.10

[dingraha]

Snopt.jl is working fine on my computer, FWIW, including the tests. I'm running RHEL 8.10, gfortran 8.5.0, Julia 1.10.4.

[BTV25]

I can no longer replicate the issue on my own system.
