macOS status

[Kirill A. Korinsky]

I'd like to summarise current macOS status.

To make things clear I've pushed changes to GCL port at MacPorts as gcl-devel subport which available here: https://github.com/catap/macports-ports/commit/3614b650ebfb259af2b1320026e00a1bef955fb7 which contains all used patches.

macOS 12 x86_64:

successfully builded.

macOS 10.5 i386

Note:

1. requires to ban system's GCC and MacPorts Clang.

2. requires to add --disable-gprof to configure options

It failed to start ./raw_pre_gcl as:

macOS 13 arm64

failed on ./configure as

checking for sbrk... yes

checking for ADDR_NO_RANDOMIZE constant... no assuming 0x40000
checking for ADDR_COMPAT_LAYOUT constant... no
checking for ADDR_LIMIT_3GB constant... no
checking for personality(ADDR_NO_RANDOMIZE) support... no
checking that sbrk is (now) non-random... no
Cannot build with randomized sbrk. Your options:
 - upgrade to a kernel/libc that knows about personality(ADDR_NO_RANDOMIZE)
 - recompile your kernel with CONFIG_COMPAT_BRK (if it has that option)
 - run sysctl kernel.randomize_va_space=0 before using gcl

macOS 13 arm64 with Xcode 15 via rosetta (x86_64)

Note:

1. configure failed on unknown target aarch64, cross compiling via rosetta with --host / --system / --target works

Anyway, failed on build; crash happened inside siLheap_report which is called by the first (init-system) at ./raw_pre_gcl
