gcc45 does not build on my system; it reports a bootstrap comparison failure. The reported error messages are

I had exactly the same problem 2 days ago, seemingly caused by an outdated port tree. After "port selfupdate; port clean gcc45; port install gcc45", the port installed successfully.

I'm having the same problem, but selfupdate -> clean -> install did not solve this for me. I'm on OS X 10.6.3.

Ditto for me as well: the update/clean/install didn't change anything.

Same problem - 10.6.3 - update/clean/install did not solve anything...

This happens to me too. Mac OS X 10.6.3. The update, clean and install didn't helped.

I built gcc45 yesterday and had no such problem. I've disabled the java compiler, though (takes hours to build, and I hate java). For what arch are you building? 64 or 32 bits?

I can't speak for anyone else, but for me the target is 64 bit, x86_64-apple-darwin10.

Strange.

If it can be useful to you, here is the output of the -v option:

To experts: could this be anything to do with XCode version? I see the same problem and I'm running 10.6.3 with XCode 3.2.2 (the latest, released April 2010).

Is there any information I could provide that would help someone diagnose this and if the XCode version is a problem, help test a fix? I'm afraid I'm not competent enough a MAC OS X programmer to take on the diagnosis / fixing task myself.

[adfernandes (Andrew Fernandes)]

Hmm... good point - I'd forgotten about the xcode point release. My failure is on 10.6.3 with the latest xcode 3.2.2, too.

[skymoo (Adam Mercer)]

I too have Xcode-3.2.2, but gcc45 built after a couple of attempts...

Can you describe what you changed between attempts?

Thanks, Chris.

As far as I know, nothing... I can't understand it...

[chris.h.green@…]

I removed XCode and Macports entirely, rebooted, re-installed XCode and MacPorts from fresh downloads and then attempted to re-install gcc45 as the first port install.

Again, comparison failures in stage3-bubble, this time in libgomp objects.

I'm at a loss. I will re-do with debug and attach the result in the hope that an expert can understand it, but this is completely beyond my understanding.

This bootstrap issue is due to the fact that libgomp has been added to the stage2 build and tickled a pre-existing issue with the tls test in configure. A race condition exists in the current tls test where the memory used is released before the test program is finished with it. A fix has been proposed for this upstream ​http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43170#c72.

[howarth@…]

Portfile diff to build with tls_configure_fix.diff.

[chris.h.green@…]

Howard, this is great, thank you!

I have (I think) applied correctly the patches you uploaded and I am rebuilding right now. I will report on how it goes.

Thanks, Chris.

[chris.h.green@…]

These patches, when applied, cause the build to be successful!

Thanks for finding the appropriate problem report, extracting the patch at issue and putting into into the correct form for macports. I'm assuming that when this fix is committed, I won't need a rebuild because the Portfile patch will show my system as already updated?

Best, Chris.

[bug@…]

How do I apply theese patches?

Btw, the same Problem exists with gcc46: ​#25091

[chris.h.green@…]

Here goes:

sudo bash -ls
wget --no-check-certificate 'https://svn.macports.org/raw-attachment/ticket/24664/Portfile-tls-configure.diff'
wget --no-check-certificate 'https://svn.macports.org/raw-attachment/ticket/24664/tls_configure_fix.diff'
port fetch gcc45
cd $(port dir gcc45)
patch -p0 < ~/Portfile-tls-configure.diff
cp ~/tls_configure_fix.diff files/
port install gcc45

If you already have a failed attempt, you'll probably want to do a:

port clean --all gcc45

first.

If you have trouble with this, let me know.

[ryandesign (Ryan Carsten Schmidt)]

You do not need to "sudo port clean --all gcc45"; that will delete the distfiles too for no good reason. A simple "sudo port clean gcc45" is sufficient.

[ryandesign (Ryan Carsten Schmidt)]

Thank you for finding this patch, Jack. Fixed for gcc45 in r68780.

The upstream bug report was fixed 2010-06-10 so we can expect to be able to remove this patch from the portfile when updating it to gcc 4.5.1.
