Make Build error

[Farockt]

When I try to build the emulation, I got this error message, and I don't know why

Any Help ?

[jcmoyer]

Outdated compiler most likely.

[Farockt]

Might be cause on the version of Apple ? Got under Ventura Mac mini M1 2020 ?

1. Update Clang to last version 19.1.7
2. Specify the compiler: "cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang .."
3. Build

I could share my compiled binaries for MacOS Intel if its ok

I just read M1. Sorry I dont know how to compile universal binaries.

[AndyGraewe]

Is anyone able to build this on MacOS arm?
Even with clang 19.1.7 it is not working for me.

I was able to build older versions though.

@AndyGraewe can you post the compile error(s) so I can see if it's something I broke?

Additional info:
I can still build version 0.5.0.
Aso with Clang version 19.1.7

[jcmoyer]

Looks like a problem with older versions of clang generally. I may have missed this because I recently upgraded my local installation of clang to version 20.x.x. This one is simple enough to work around so I'll push a patch later today.
