#64896: gcc and gcc-devel run fails libSystem.B.dylib not found

[Alan Needleman]

Thank you very much for your response.

I apologize for being imprecise.

1. The computer is a 2020 MacBook Air m1 and the operating system is MacOS 12.3. However, I have the same problem on a 2013 Intel MacBook Pro running MacOS 11.6.5.

2. The code is a Fortran code that I compiled using gfortran. The code solves partial differential equations for scientific modeling.

3. The basic problem is that the code has large static arrays so the static storage exceeds 4 GBytes. It seems odd to me that a modern 64bit computer and operating system is limited to 32bit addressing for arrays.

4. I had found the URLs you listed in your email but I didn’t find them helpful. That could certainly be because I didn’t fully understand them. My limitation.

Many thanks for your reply anyway. Much appreciated.

Best regards.

Alan
