Library Not Found

Platform: Mac OS Sonoma (14.0)
Solver Version: May 2023
svSolver Version: July 2022

Hello, I am trying to run a cfd simulation using Simvascular and the svSolver plugin using the platform and versions above. However, when I try to create the simulation file, I get the following error:

dyld[88318]: Library not loaded: /usr/local/opt/gcc/lib/gcc/11/libgfortran.5.dylib

I have tried several methods to locate and/or install gfortran, but I can't seem to find it. I also tried uninstalling and reinstalling Simvascular and svSolver, but that did not fix the issue either. I would appreciate any and all help or advice.

Hello,

The latest svSolver MacOS installer (BigSur) was built using GCC 11.3.0 so when the executable runs it is looking for gcc/11/libgfortran.5.dylib. What GCC version do you have installed?

There are two things you can try

1) Install GCC 11

2) Build svSolver from source (see https://github.com/SimVascular/svSolver)

Option 1) may still not work (search the Forum for other user's experiences).

Option 2) is probably the best solution

In the mean time I will try to setup building svSolver for MacOS Sonoma.

Cheers,
Dave

Hi,

I had a student run into this issue as well. Installing gcc using homebrew (https://brew.sh/) worked for them.

Best,
