Configuring GCC 10.3 on PPC Mac OS X 10.4.11/Tiger for build reveals problems when removing relics

Configuring GCC 10.3 on PPC Mac OS X 10.4.11/Tiger for build reveals problems when removing relics

[Peter Dyballa]

Hello!

On Mac OS X/macOS configure scripts leave conftest.dSYM subdirectories behind, created by dsymutil:

	checking for build system preprocessor... rm: conftest.dSYM: is a directory
	checking for build system executable suffix... rm: conftest.dSYM: is a directory
	checking whether build system compiler is ANSI... rm: conftest.dSYM: is a directory
	checking for build system compiler math library... rm: conftest.dSYM: is a directory

Building GCC 10.3 with MacPorts the configure scripts produce 178 such reports (and more than 11,000 checking lines without complaint). (The relation is worse when building smaller software packages.)

Is it possible to replace the simple "rm" with "rm -r", at least on darwin, the macOS/Mac OS X? Or create a special macro to be used when dsymutil gets involved?

Greetings

I agree it’s an irritation (although not a show-stopper, so other things are higher priority right now on my list).

It is likely to be possible, where the configure tests can be modified in the GCC sources.

The best course of action is to take them one by one and see where the configure source comes from, go to that source and modify the rm (hopefully, conditionally on *-*-darwin*) to deal with this.  If the source of the problems is primarily libtool.m4 … then we do make local modifications, but now that (libtool) is maintained again we should look into how much we can sync with upstream.

I’m happy to review patches (if they are macOS/darwin-specific, then I can even approve them).
