Did you upgrade to bash-3.2 ?

[Comment 2 Andrija Prčić 2006-10-13 04:09:23 UTC]

I also have the same problem with using kdebase-meta.
To be more precise kde-base/kdepasswd fails.
I'm using ~amd64, and I have upgraded to bash 3.2

[Comment 6 Dan Snis 2006-10-13 05:15:55 UTC]

I'd masked =app-shells/bash-3.2 localy in /etc/portage/package.mask
Now all problematic ebuilds are compiling as they should.

In the process of running an 'emerge --sync' then 'emerge -uDv world', 
bash-3.2 ran first.

After reporting the bug, I ran 'etc-update', which updated some kde files and 
then again ran 'emerge -uDv world'. Kdebase-3.5.5 failed in the same place.

[Comment 8 Jakub Moc (RETIRED) 2006-10-13 05:43:34 UTC]

Just FYI, bash-3.2 is now package.masked

[Comment 9 Bob Reveley 2006-10-13 05:45:16 UTC]

Created attachment 99527 [details]
kdebase-3.5.5 config.log

[Comment 10 Diego Elio Pettenò (RETIRED) 2006-10-13 06:12:44 UTC]

Seems like I found the problem, and this is bash-style breakage of rules..

    ac_cv_maxpathlen=`sed 's#KDE_HELLO ##' conftest.out`

bash handles one of the # as a comment separator (probably the one with a space before it), even if it's in a non-expansion string (''):

:3: checking for MAXPATHLEN
checking for MAXPATHLEN...
test.bash: line 30: unexpected EOF while looking for matching ``'
test.bash: line 39: syntax error: unexpected end of file

zsh, BSD's ash, bb and bash < 3.2 handle the thing correctly, but bash 3.2 seems not to.

I can work it around, but seems like a bug to me. Bad bash!

Doesn't your test say that it's a "`" that it can't find the match for rather than "#"? Looks like I backup to bash-3.1_p17 to get a look at kde-3.5.5.

[Comment 12 Diego Elio Pettenò (RETIRED) 2006-10-13 06:32:19 UTC]

It can't find ` because the closing ` is considered out of the comment.
The error appears about 1000 lines below the point where MAXPATHLEN test is started (which fooled me up for a bit) because it needs to close first a ' and then a `.

[Comment 13 Bob Reveley 2006-10-13 06:40:03 UTC]

Right. Bad bash. Looks like we'll get a better bash out of it. Good lookin' out.
