Description Tudor Vaida 2004-06-12 12:33:50 UTC

After emerging some qt applications ( mixxx and bpmdj ) ( I have no KDE environment installed ), I observed they keep segfaulting. I tried choosing less agressive compile flags, result the same.
I found a hint on its incompatibility with QT on a Debian forum ( linke given above ). It seems the reason was that I had ACCEPT_KEYWORDS="~x86" which permitted the install of gcc-3.3.3-r5.  so I tried removing the line from make.conf and choosing less aggressive compile flags ( -O2 - pipe ). With the older gcc stable version ( 3.3.2-r5 ) the QT applications seems to work ok ( after recompiling with --emptytree ).

Reproducible: Didn't try

Comment 1 Tudor Vaida 2004-06-13 04:22:10 UTC

I corrected the bug, seems like applications are still segfaulting only because of clicking a window or so.

Comment 2 Tudor Vaida 2004-06-13 05:12:18 UTC

Seems like mixxx really had a segfaulting bug, and bpm-dj also has other such bugs, so I guess it's not up to the compiler, but these are problems in the code itself.
Since both mixxx and bpmdj have quite outdated versions in the portage tree, I will close the bug for now. If I still encounter problems I will reopen it.
