Crashing Time

[sakshale]

After upgrading my compiler, I can now succesfully build and install showeq again. However, with now EQ client running on the target system (no one home to start one) I get an immediate segfault upon startup.

[high_jeeves]

Did you rebuild QT with the new compiler? That would be my first shot

You might want to start posting these help requests on the help forum..

Sorry about posting in the wrong forum...

Rebuilding Qt was a great suggestion. I should have done that first. However, it didn't cure the problems, but the traces did change.

I have a sinking feeling that I may have a real hardware problem under all of this. Because, now every trace is slightly different... here are two.

I dunno if it will make any difference but, Did you recompile SEQ after you recompiled QT? and is $QTDIR set to the right directory?

[sakshale]

Well, I've rebuild Qt and ShowEQ multiple times, double checking all the options. It still seqfaults on startup. (Note: always the same)

I figure that I have a corrupt library somewhere, so next step is a OS reinstall....

Qt: gdb: -nograb added to command-line options.
Use the -dograb option to enforce grabbing.

[fryfrog]

well, this should be in the help thread...

but also, when they say "did you re-build qt" they MEAN "did you rebuild qt using gcc3, then re-build showeq using gcc3". this IS a must. just compiling qt will result in it using your "normal" gcc (usually 2.9x). you actually HAVE to edit a file in the qt source (qt-src/configs/linux-g++-shared i think) and change all references to "gcc" to "gcc3/gcc-3.0/gcc-3.0.1/gcc-3.0.4" and all "g++" to "g++3/g++-3.0/g++-3.0.1/g++-3.0.4". that was "redhat/gentoo/mdk 8.1/mdk 8.2" names for gcc3 btw. be sure you have ALL the gcc3 stuff installed, should be between 4 and 6 rpms on rh and mdk.
