defect: build of libgcc 4.9.1 fails on PPC Leopard (Mac OS X 10.5.8) because of "Bootstrap comparison failure!"

When I started a new install, without debug option, port continued to build and install libgcc and now I have

  libgcc @4.9.1_0 (active)

[ryandesign (Ryan Carsten Schmidt)]

When you say "debug option" do you mean the -d flag, as in sudo port -d install gcc49, or do you mean something else? The debug flag doesn't change how the build works, only how much information MacPorts displays about it.

I meant port's -d flag.

[ryandesign (Ryan Carsten Schmidt)]

I think I experience the same error with libgcc @4.9.2_1, also on Leopard PowerPC. I'll attach my log.

Is this consistently reproducible?

I think I experience the same error with libgcc @4.9.2_1, also on Leopard PowerPC.

For me the builds of libgcc and gcc@4.9.2_1 succeeded both without differences in the stages…

[ryandesign (Ryan Carsten Schmidt)]

After a clean and retry and another 7 hours of building, it failed for me with the same error again.

Did your Mac have all the time enough free disk space?

Yes, as far as I remember.

I got the "Bootstrap comparison failure" error in the log when building libgcc@4.9.2_1 on my 10.4.11 PowerPC. I had interrupted (Ctrl-C) the build a couple of times and started it again (with a plain "port build"). However, after a "port clean" the build finished without problems. I suspect this might be a problem in gcc own Makefiles requiring a clean build directory for bootstrap.

[ballapete (Peter "Pete" Dyballa)]

Replying to csanchezdll@…:

I also encountered these failures on PPC. Someone suggested this might have been caused by missing disk space. My way of building the packages happens in GNU Emacs. Since I know that the build of GCC 4.x can take days I start the upgrade some time and leave it run in GNU Emacs. Once a day I check whether the build still continues. And this is performed from inside a Terminal of my MacBook with an SSH session on Tiger or Leopard. Simply running w shows the load, and when it's higher than one, then the build continues. So it's not likely that some "interrupt" happened.

Anyway, I started a new build, having almost 6 GB of free disk space…

Actually the build did not take long… It took long for me to look after it! After less than a day it ended here:

So this time it's the new (?) ld that fails, as it does with gcc48 @4.8.4, see Ticket #46677. Maybe ld64 should be chosen for the job… GCC49 @4.9.2 builds fine with the setting "port:ld64" in the depends_lib section.

I was able to build libgcc @4.9.2_1 on a PowerBook G4 by first explicitly choosing ld64 +ld64_97. (By default, ld64 installs with the variant +ld64_127 on PowerBook G4's running Leopard.) See the ticket #46801 for the build logs for libgcc.
