qt compiling woes-Beware n00bish questions :)


So I'm trying to compile qt to get the latest version of KDE to run-I run ./configure -system-zlib -qt-gif -system-libpng -system-libjpeg -plugin-imgfmt-mng -thread -no-stl -no-g++-exceptions, then I run make, and I get this error that says:

/usr/lib/qt/bin/moc: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
make[2] : *** [.moc/release-shared-mt/qapplication_x11.moc] Error 127
make[2]: Leaving directory `/usr/lib/qt/src'
make[1]: *** [sub=src] Error 2
make[1]: Leaving directory `/usr/lib/qt'
make: *** [init] Error 2

Anyone know how I can get make to run on qt? Running RH9, and both "make" and "/usr/bin/gmake" yield the same results

Thanks much.

what version of gcc you got there ?
redhat9 came with gcc 3.2.2 yes ?
unfortunately that was libstdc++.so.5
i think libstdc++.so.6 is the gcc 3.4 series
gcc is not a reverse compatable thing so don't replace your old one
but you can try compiling new gcc from source with --prefix=/opt/gcc-3.4
then copy the lib into /usr/lib and see if it will fly
can't imagine if it will work
you can even use the newer compiler to compile stuff but you glibc is compiled with
gcc 3.2 and this sounds like a train wreck in the making
but as long as no system files in /usr are overwriten no harm just be carefull

Okay, I'm a teeny bit fuzzy on what you're suggesting...I'll try to bear with you though.

You want me to compile the new GCC using the old one, with that --prefix option?

Because...that would mean using ./configure, make, make install, which is where it fails. Kind of a catch-22, isn't it? I think? Unless there's a way to force it to use the old GCC that was already installed?

Heh, these were the n00b questions I warned of. I think what I need is kind of an if/then step-by-step fix. I know it's asking a lot, and I wish I knew more. So many online guides assume a level of knowledge far greater than what I really have, though. Thanks for helping, I really appreciate it.

Also, should I rmdir the gcc directory in my /home, or just leave that be? It's where I untarred and compiled the new GCC.

Thanks,
CelticWhisper
