gcc fails to compile on macOS Sonoma (14.1)

[CezaryKulakowski]

I have macbook pro 16' with Intel i9. I go through the configuration list from README. Compilation of the gcc fails with following errors:

see #336, #341

[CezaryKulakowski]

It seems the solution proposed in #336 doesn't work anymore as it's not possible to downgade isl:

brew install isl@0.18
Error: isl@0.18 has been disabled because it is a versioned formula!

[CezaryKulakowski]

According to information from here https://raw.githubusercontent.com/Homebrew/homebrew-core/master/Formula/i/isl%400.18.rb isl in version 0.18 is disabled since 2023-10-03 so it's no longer possible to install it via brew.

[bebbo]

then use the other solution: https://github.com/bebbo/amiga-gcc/issues/341#issuecomment-1537429618

[CezaryKulakowski]

I fetched isl 0.18 from https://libisl.sourceforge.io/isl-0.18.tar.xz and I built and installed it manually (configure/make/make install). It solved the problem.

[bebbo]

that's what contrib/download_prerequisites does too: it downloads matching verions of isl, gmp, mpc and mpfr and the Makefile automatically picks that up.
