ok, so likely that really is the name the symbol should have in Qt. > I have some weird results here: > @pingouRed ~]$ strings /usr/bin/rkward.bin | grep "lastIndexOf" > _ZNK7QString11lastIndexOfER7QRegExpi > ----- From the computer on which rkward crashes > @pingouLab ~]$ strings /usr/bin/rkward.bin | grep "lastIndexOf" > _ZNK7QString11lastIndexOfERK7QRegExpi > ----- From the computer on which rkward does *not* crash Yes, this is weird. Really weird. And this is likely to be close to the heart of the problem. In the crashing rkward binary the symbol name is quite simply mis-spelled, so no surprise the symbol cannot be found at run-time. Now the question is - why does this happen. I don't see how RKWard code could be to blame (but if you want to look, or toy with some modifications, the relevant function is in rkward/misc/rkcommonfunctions.cpp, getCurrentSymbolOffset()). I'd guess the linker is to blame, somehow, but this is beyond me. Could you try to compile with a different version of gcc/g++, without changing any other details? Perhaps this could serve to pin the problem to some specific version. All in all, I still don't have an idea on this. This really looks strange. Right now, I don't think the problem is in RKWard code. My best advice is to ask for help on a mailing list concerned with packaging KDE, Qt or C++ apps for Fedora, but keep us posted on any new insights / thoughts / questions. Maybe somebody on this list will have an idea, too. Regards Thomas
