I just installed xcode 15 (because git wouldn't work without doing so). I didn't note what version I had before.
Now I can't compile some c++ code, which was compiling perfectly well before. when I try to make, the following output is shown:
g++-mp-12 -std=c++14 -Wall -O3 -fopenmp -o owt1d-nonlocal main.o linear.o nonlinear.o read.o energy.o intensity.o spectrum.o initialise.o flux.o fourier.o -L/opt/local/lib -framework Accelerate -march=native -lfftw3 -lfftw3_threads -lopenblas -larmadillo -lm -lpthread
-macosx_version_min has been renamed to -macos_version_min

I installed c++ and all the libraries used for this code with MacPorts, and I have tried updating all my installed ports, but the same error is produced.
I'm really not sure about going into the guts of the installations, and don't know where to start resolving the duplicate paths. Is there an easy fix? Or will I have to try downgrading my version of xcode (not ideal)?
I have the same problem. Xcode15 was automatically installed and since then I can no longer link my code with gcc. The only solution that worked was to reinstall Xcode 14.3.1 from the Apple developer site.
