[Linux] Supermodel now fails to compile about supermodel HOT 5 CLOSED

Did you compile with the -j switch?
Try a fresh recompile without it.
A while back gcc hit a problem where it would run wild with -j. Somewhere around version 12 IIRC.
That's when I stopped using that switch.

FWIW
It's compiling ok for me in a slightly old version of Ubuntu and Manjaro.
Also ok in latest Win/MSYS.

Just tried it on gcc 13.2.0 in Windows, no problems there. I think ToBul may be correct: parallel builds with -j can get screwed up. I'm not sure why. To me, the Musashi build rules look correctly specified.

Thanks guys, good advice. It's compiling for me after trying again here too, so I'll close this. I am indeed building with -j9 on an 8-core, 16-thread CPU. I too had intermittent issues compiling supermodel with -j several years ago, though suddenly it stopped, I presume due to some specific commit. At least the blessing here is that we have a very narrow set of commits that seem to cause it to happen again, if that helps to trace the issue and resolve it once and for all, to avoid frivolous issue reports like this one in the future. On the other hand it may not be worth the effort.

It's not the commits. It's the Makefile that's the problem. The Musashi 68K core includes a build step where an intermediate program has to be compiled and then used to generate the source code. I think the problem is that make is computing dependencies incorrectly and compiling before all files are ready.

Thanks for the explanation. That makes sense, just curious why the issue hasn't surfaced for me in quite a while. Perhaps it just occurs less frequently now.
