LA compilation failed

[John Zhang]

Dear Developers

I tried to install NewtonX-2.4-B06 using gfortran (tried various version from 8.5 to 12.2). The installation failed when compiling LA. It alway stopped when compiling noncblas.cc. The error message looks like (pasted at the end of this message). Any suggestion? Thanks!

Best wishes

John
