Bug 37672 – kdelibs refuses to emerge because of dcopidl raising a SIGFPE

• Status: RESOLVED CANTFIX
• Product: Gentoo Linux

[Description Felix Riemann 2004-01-09 03:37:05 UTC]

When I try to emerge kdelibs, the ebuild stops without an actual error message on file ksycoca.kidl. Further investigation shoed that the (newly build) dcopidl and dcop2cpp raise a floating-point exception (SIGFPE) when executed. Even with reduced CFLAGS.
While searching on google I found another user having the same problem, which seems somehow related to either the kernel 2.6 (what I can't believe) or to nptl (which I use too): http://groups.google.de/groups?hl=de&lr=&ie=UTF-8&oe=UTF-8&selm=17x8G-9W-15%40gated-at.bofh.it&rnum=1

The whole bug appeared after making a stage1 build of gentoo with a 2.6-kernel and nptl.

Reproducible: Always
Steps to Reproduce:
1. emerge kdelibs with an 2.6-kernel and nptl enabled (maybe from bootstrapping time on)
2.
3.

Expected Results:  
It should have emerged cleanly.

What's with the -O4 in your cflags?

Also, did you remove all cached files before re-emerging after toning down your cflags.  Those are pretty aggressive.

[Comment 2 Felix Riemann 2004-01-09 11:21:57 UTC]

Yes, I tried it with portage defaults (-O2 -mcpu=i686 -funroll-loops -pipe), but the result is the same. I tried downgrading glibc to 2.3.2-r9 too, but it changed nothing.

[Comment 3 Felix Riemann 2004-01-15 08:52:45 UTC]

The same happens with kdelibs-3.1.5.

[Comment 4 Felix Riemann 2004-01-19 05:53:42 UTC]

Well, it looks like upgrading Qt to 3.3.0b1 fixed it here. kdelibs and kdebase compiled fine afterwards.

[Comment 5 Weihua Zhou 2004-02-19 16:43:30 UTC]

My Qt is 3.3.0, kdelibs 3.2.0 can't be installed. The kernel is 2.4.22-r5. It just shows the same error information 

Portage 2.0.50-r1
glibc 2.3.2-r9
gcc 3.3.2-r5

[Comment 6 Caleb Tennis (RETIRED) 2004-04-26 18:22:47 UTC]

something local - the glibc prerelease probably isn't helping.

upgrade gcc/glibc, and try again.
