atlas @3.9.47: build fails on PPC G4 under Leopard

[razzfazz@…]

When trying to update atlas on my PowerBook G4 under Leopard 10.5.8, I get the following build failure:

razzepb:~ dub$ port installed atlas
The following ports are currently installed:

It looks like this issue had previously been fixed in #28413 for atlas 3.9.33, but apparently it has somehow been re-introduced since then.

Please remember to cc the maintainer.

This is a regression in Atlas code, the flag used to be added by the configuration mechanism without having to specify it. I've changed the Portfile in r82453 so that it is included in the compilation flags. Update and try again.

and got the same error. Attaching the log.

Latest failed to build log.

Ok, I see. I've witnessed the same phenomenon using clang. At some point, the Atlas build system puts aside what you told it to use (compiler and flags) and forces the use of gcc with some weird options. That's what cause your error, and that is maybe why Atlas does not compile with clang. I'm going to report that upstream and see what I can do meanwhile about it.

I am trying to upgrade atlas on a G5 machine, and i am also getting an error (it also failed with .46 as well). On this machine I get the following warning as well:

--->  Configuring atlas
--- Compiling for G4 arch (ppc) on a G5 (ppc64) machine.
--- This will lead to inferior performance.
--->  Building atlas
Error: Target org.macports.build returned: shell command failed (see log for details)

Error: Unable to upgrade port: 1

Atlas was installed as a dependency to something else, and so is configured with +gcc44.

Cc Me!

[vince@…]

I've committed a patch in r82670. I hope it will solve this issue. Please update and try again.

[jmr@…]

Why did you revert r82612? And where is patch-clang.diff?

[vince@…]

Sorry Josh, it was a just a silly mistake of mine. r82683 should be correct (and puts patch-clang.diff in). Thanks for pointing this out.

[dersh@…]

I just did a sync and upgrade, but got the same error:

I can post the new log if that might help.

thanks,

Sorry for being so inefficient, but I have no G4 computer at hand and Atlas, as you might have realized, is really complex (I wouldn't say it’s a piece of c* but sometimes it comes close). What happens is that, at some point (still unknown), the standard compiler and options defined in the Portfile get overridden by a mere “gcc”, for whatever unknown and surely stupid reason. Result: the -force… flag is discarded and the build fails.

I have reported a bunch of bugs upstream, but Clint, the unique maintainer of Atlas, seems in vacation. I hope to get a fix before his return.

[vince@…]

I have committed some further patches in r82700. Update, try again and while compiling light a candle at the nearest church!

[dersh@…]

Thank you much for working on this. No luck. Same errors with the new version.

[vince@…]

No luck :( I give up for tonight, I hope I find something more potent tomorrow.

[vince@…]

I just noticed (after a good sleep, things are somewhat neater) that I inadvertently removed at some point from the Portfile the patch that was intended to fix this bug. I have reincorporated it in r82722, so please try once more… with good hope this time.

[dersh@…]

Sleep solved it! It now builds for me.

Thank you!

[vince@…]

Hurrah at last! That's was my fault: I am the one to blame, since I made the mistake. I apologize for the delay. Sorry once again. Have fun.

The fix worked. Thank you.
