Well, I run portage-2.1 locally and haven't seen this problem building mozilla-firefox-1.5.* once. When I run `genlop mozilla-firefox` I see that I've built quite a few of them: Sat Feb 11 14:26:11 2006 >>> www-client/mozilla-firefox-1.5.0.1-r1 Sun Mar 5 10:33:16 2006 >>> www-client/mozilla-firefox-1.5.0.1-r2 Sun Mar 26 04:30:42 2006 >>> www-client/mozilla-firefox-1.5.0.1-r3 Sun Apr 2 05:21:04 2006 >>> www-client/mozilla-firefox-1.5.0.1-r4 Sun Apr 23 12:48:02 2006 >>> www-client/mozilla-firefox-1.5.0.2 Sat May 6 17:09:20 2006 >>> www-client/mozilla-firefox-1.5.0.3 Mark, how many times have you been able to reproduce this with portage-2.1?

I'm not really familiar with autotools but I did some googling and section 15.6.2 of the autoconf manual mentions a error that is practically identical here: http://www.gnu.org/software/autoconf/manual/autoconf-2.57/html_node/autoconf_163.html Does anyone with more autotools familiarity know if that information is useful for this bug?
I found that link, too. That's why I tried unmerging autoconf 2.5* .
*** Bug 136653 has been marked as a duplicate of this bug. ***
I really wonder how is undefined autoconf macro related to portage... Please, reassign this thing back to mozilla or base-system folks.
Since this doesn't affect very many people, it must to be something strange in the user's build environment that causes it. Perhaps /var/tmp/portage/mozilla-firefox-1.5.0.3/temp/environment or the equivalent (or emerge --debug outpout) will be helpful in debugging this. I agree with with Jakub that this problem isn't caused directly by portage (considering that most people are unable to reproduce it).

I am many other devs are unable to dupicate the problem and I do not have time to be chasing bugs that are unreproducable.
(In reply to comment #9) > Created an attachment (id=89075) [edit] > /var/tmp/portage/mozilla-firefox-1.5.0.4/temp/environment I did a unified diff of your environment vs. mine (from a successul compile) but there wasn't much difference. The emerge --debug log also looks vary similar to mine. Jakub, I don't know what we do with bugs mysterious bugs that most people can't reproduce. I suppose this is sort of a NEEDINFO, until somebody finds out what causes it.
Just for full clarity here I am gonna attach a diff for firefox-1.5.0.4 ebuild if someone can test and confirms it makes a difference I will added it to the tree.
Created attachment 89109 [details] autoconf patch dep All this is gonna do is introduce a dep on autoconf-2.13. I doubt this is gonna address the issue at hand here but one can only hope.
(In reply to comment #14) > All this is gonna do is introduce a dep on autoconf-2.13. I doubt this is gonna > address the issue at hand here but one can only hope. Well, if someone is missing this one, his system is for sure messed up. Are you doing something like WANT_AUTOCONF=2.1 somewhere in the eclasses? That would be more helpful here, I'd say.
I am one of the end users experincing this issue. My build environment does use autoconf-2.59-r7 because that is the package marked as stable in portage. Masking this package in an attempt to revert to autoconf-2.13 causes a lot of other dependancies to fail in the build system. I'd prefer not to break a working build system for these two packages. Is there a way to have both autoconf versions side-by-side (slotted maybe?) and this package could choose to use 2.13 (if that does indeed solve the issue?) I'll be happy to help debug since it you guys don't have a system with this problem. Are the maintainers all using autoconf-2.13?
(In reply to comment #16) > Is there a way to have both autoconf versions side-by-side (slotted maybe?) and > this package could choose to use 2.13 (if that does indeed solve the issue?) Huh? It's the *default*. You have broken system if you are missing autoconf-2.1*. > I'll be happy to help debug since it you guys don't have a system with this > problem. Are the maintainers all using autoconf-2.13? If you unmerged autoconf-2.1*, then re-emerge it. Those two versions are slotted and should be installed on every Gentoo system. sys-devel/autoconf-wrapper depends on both of them and is in profiles/base/packages.
How would I be able to tell? brian jharuska # emerge -vp autoconf These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild R ] sys-devel/autoconf-2.59-r7 USE="-emacs" 0 kB
(In reply to comment #18) emerge -pv autoconf-wrapper; I've explained it above already.
Sorry, I must be dense because I don't follow. How would I unemerge a version of autoconf that my machine doesn't think I have? From the emerge command, it doesn't seem like it is slotted. Are you sure of your comments above? I understand these bugs are annoying because it is working for you. You'll have to walk me through what you'd like since I'm not a package maintainer and don't quite understand what you're asking for. brian autoconf # emerge -pv autoconf-wrapper These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild R ] sys-devel/autoconf-wrapper-3-r1 0 kB
Apologize again for the double post. I see from my emerge --info (bug 136653) that I do have both. I will attempt to unmerge, and re-emerge but I'm not sure what that would solve. I'll also apply your patch to the ebuild.
Just to shine some light, autoconf is SLOTTED, and emerge looks at the latest slot by default. tryone one of: emerge -Cp autoconf which will list all autoconfs isntalled (and probably complain a lot ;) ) or: emerge -pv =autoconf-2.1* which will give you the 2.1 slot and not the 2.5 slot.

Go and read the documentation on --prune.

That WANT_AUTOMAKE is a little bit more of *cough* an issue. There is no version 2.1 or 2.13. The choices (presently) are 1.4 through 1.9 with the default being 1.9 - also clearly documented at the top of /usr/bin/automake.
Well, I just rearranged my partitions and thus had to do a clean install of 2006.0, and it now works. Thus, the problem must be some file from 2005.1 (or just happened to be on my system) that wasn't affected by emerge -e world.
If you run WANT_AUTOCONF="2.1"
My version of /usr/portage/www-client/mozilla-firefox/mozilla-firefox-1.5.0.4.ebuild has: WANT_AUTOCONF="2.1" \ eautoreconf || die "failed running eautoreconf" It certainly does not have WANT_AUTOCONF="2.13". However, i did have similar symptoms to the original problem here. If you run: WANT_AUTOCONF="2.1" autoconf --version Are you getting 2.13? For me some annoying, unidentified program had managed to install another version of autoconf (2.59) in an unexpected place (/usr/local/bin) and i was picking that version up instead of the wrapper that properly selects 2.1 or 2.5 (/usr/bin/autoconf). But i guess with a fresh install this is all moot for you anyway.
I have 2 Gentoo machines and only one is having this problem. - In the machine with the problem, I have: WANT_AUTOCONF="2.1" autoconf --version autoconf (GNU Autoconf) 2.59 ... - In the other machine, I have: WANT_AUTOCONF="2.1" autoconf --version Autoconf version 2.13 ... Both have autoconf 2.13 and 2.59 installed. In the machine with the problem I've reemerged both autoconf-2.1* and autoconf-wrapper (I even 'emerge -C' and reemerge the wrapper) and this did not solve the problem.
