Hey guys, I'm having trouble to run meshing in neper. The Output, e.g. for ./neper -M says:

========================    N   e   p   e   r    =======================

4.9.1
Error  :     > Option `-gmsh' does not provide a valid path to the gmsh binary.
Aborted (core dumped)

Gmsh is build from source, installed and runs fine: echo $(which gmsh) $(gmsh --version) => /home/sash/local/bin/gmsh 4.9.1

Other than for meshing, neper passes all test. I have tried starting neper with pointing to the Gmsh executable ./neper -M -gmsh $(which gmsh) which causes the same error. Any Ideas what's the problem here ? Thanks in advance!

This was due to a change in Gmsh. Thanks @5A5H for the bug report!

Fixed in version 4.2.1-20.

Hi Dr. Quey, the same problem occured to me as I got the version 4.1.2 installed.

Since I am running the program using windows, this is the latest version that I can get from anaconda. I had several other environment issues installing the latest version.

Any ideas how I can fix the change in Gmsh problem with this old version?

Thank you very much, Maohua

What is your Neper version? Is Gmsh available at the command line, as gmsh? Did you run Neper's tests?

The problem got solved after I managed to install the latest version, thank you, Dr. Quey!
