| [photran] Need help with new Eclipse install for Fortran (resend) |
| I’ve been developing Fortran programs in Eclipse (now at 2022-03) for years on Macintosh. This is working correctly on an iMac 2014 running Big Sur (macOS 11.7.3). I have now migrated to an M2 Mac mini running Ventura (macOS 13.2) and while previously built Fortran apps still run I can’t build a new one. Here’s the build error: 10:09:20 **** Build of configuration Release for project Fortrantest2023 **** make all Building file: ../Fortrantest2023.f95 Invoking: GNU Fortran Compiler /usr/local/gfortran/bin/gfortran -funderscoring -O3 -Wall -c -fmessage-length=0 -o "Fortrantest2023.o" "../Fortrantest2023.f95" Finished building: ../Fortrantest2023.f95
Building target: Fortrantest2023 Invoking: MacOS X Fortran Linker /usr/local/gfortran/bin/gfortran -o "Fortrantest2023" ./Fortrantest2023.o ld: library not found for -lSystem collect2: error: ld returned 1 exit status make: *** [Fortrantest2023] Error 1 "make all" terminated with exit code 2. Build might be incomplete. 10:09:23 Build Failed. 2 errors, 0 warnings. (took 3s.113ms) Can anyone please tell me what I need to do to correct this. Presumably there is some library somewhere that needs to be installed or linked. This is a trivial test program that computes square root using the traditional iterative method. It works on my old machine. Thank you! Bernard Abramson |
