Hi, I got a Mac silicon (M2 chip) running on OS Ventura 13.5.2 (22G91). I installed XCODE, command line utilities, and gfortran from Git Hub. Compilation of the code is remarkable; however, during execution, I encountered the following error described below, which indicates that I am missing libSystem.B.dylib. This error only occurs in Mac Silicon computers. The code runs remarkably in my Mac Intel processor. I would appreciate any help you can give me. Thank you *** Running sample case ./n-Pb208-nngamma/new dyld[60769]: dyld cache '(null)' not loaded: syscall to map cache into shared region failed dyld[60769]: Library not loaded: /usr/lib/libSystem.B.dylib Referenced from: <28252600-BB7B-336B-AB15-3687F43881F0> /Users/gamalakabani/Applications/TALYS_CODE/talys/bin/talys Reason: tried: '/usr/lib/libSystem.B.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/libSystem.B.dylib' (no such file), '/usr/lib/libSystem.B.dylib' (no such file, no dyld cache), '/usr/local/lib/libSystem.B.dylib' (no such file) ./verify: line 12: 60769 Abort trap: 6 $talys < talys.inp > talys.out Gamal Akabani
