Home Page Forums MAME Non-Windows MAME Support Can't run MAME 0.216 on macOS

So, this is a new one: when trying to start my freshly compiled MAME 0.216 using Xcode 11.2.1 under Catalina, I'm getting the following error:



I did not observe anything special during compilation (but I did not pay special attention either).

I had no problems using the previous version on macOS 10.15 (using the same version of Xcode, maybe 0.1 version earlier).

What does 'file MAME' say?

data

Is it missing the executable bit?

Edit: doesn't seem so:

You're not trying to run a 32-bit build, are you? Catalina completely removes support for 32-bit executables.

Again, what does 'file MAME' say? It should be like this:

It says "data" (see above). I checked with Go64, it's not a 64 bit app.

I tried another compilation, this time using the internal SSD and not the external Thunderbolt disk. MAME works fine now.

I noticed the file was 56 byte shorter and now showed the version number in the macOS Get Info dialog, which the previous one did not.

Hmm. Disk location shouldn't matter, but at least it's resolved

Exactly my thoughts
