--- Comment #11 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to Thomas Koenig from comment #10) > Since there is no other viable Fortran compiler on iOS, AFAIK, iOS has not been supported by GCC since Apple gcc-4.2.1 and the Apple releases didn't have gfortran. this applies to the shift of macOS to arm64. (although, ironically, supporting arm64 GCC on macOS would bring support to iOS too). > this means that packages like R, numpy and anything else will not > work on the new hardware. > > I guess the advice will just have to be: Do not buy any new-style > Macs if you plan to do any scientific work at all until this has > been resolved. https://github.com/iains/gcc-darwin-arm64#readme .. but a volunteer effort and vying for time with every other bug / enhancement.
