JackLockedEngine.h: internal compiler error: in objc_eh_runtime_type, at objc/objc-next-runtime-abi-01.cc

[falkTX]

an internal compiler error is not an issue in jack2 but in the compiler. not much we can do to fix this

[falkTX]

You can always try to disable optimizations, either globally or in that specific part of the code by use of __attribute__((optnone))

@falkTX Thank you for responding. Yes, I understand ICE is not your bug, but maybe you could suggest a possible workaround? It it something not generally acceptable, we can have a local patch in Macports to use only with GCC.
Otherwise jack is broken, at least on PowerPC where no Clang works.

P. S. I need to check, but I recall GCC upstream is aware of the problem, but ObjC no one cares.

I will try that, thank you. For GCC, apparently __attribute__((optimize(0))) is correct one: argtable/argtable3@7704006

@falkTX Unfortunately, building the whole thing with -O0 (was easier to try and has the same effect as setting respective __attribute__, I assume) did not help, same ICE.

In the meanwhile, a couple of headers are missing in macosx files: #951

I have found a ticket on GCC Bugzilla, it is a bug in GCC for 32-bit targets:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61759

@alarixnia Could you say if jack2 builds via pkgsrc for Darwin ppc? If you know or could check.

@alarixnia Could you say if jack2 builds via pkgsrc for Darwin ppc? If you know or could check.

A dependency of it requires CMake and I don't have a compiler capable of building CMake for Darwin/ppc.

Unless that dependency is extremely picky, CMake 3.9.6 builds without C++11.
Also, gcc7 and gcc10 build on 10.4.11. I think even gcc13 (though gcc13 requires C++11, so one must build gcc7 or gcc10 first).
