Qt and lstdc++

Half_Elf · 04-04-2002, 11:44 AM

Qt refuse to compile on my box. It's not my first post about that, last time someone suggest me to reinstall automake/autconf....
That was not the problem it seems.

So here is the eror I got each time I tried to installl Qt:
I already tried some version of Qt, but I got this error each time.
I (not so) recently installed a strange version of Qt I found on my box (qt-x11-2.2.4.tar.gz) I think it was working before, maybe it broke something?

g++ -o ./moc mocgen.o qbuffer.o qcollection.o qcstring.o qdatastream.o qdatetime.o qfile.o qgarray.o qgdict.o qglist.o qglobal.o qgvector.o qiodevice.o qregexp.o qstring.o qtextcodec.o qtextstream.o qfile_unix.o
/usr/bin/ld: cannot find -lstdc++
collect2: ld returned 1 exit status
make[2]: *** [moc] Error 1
make[2]: Leaving directory `/usr/local/qt/src/moc'
make[1]: *** [src-moc] Error 2
make[1]: Leaving directory `/usr/local/qt'
make: *** [init] Error 2

Anyone can tell me what the hell is ld and lstdc++??????

ls is the GNU linker, it takes a bunch of object files (.o's) and makes a single executable out of them, -lbstdc++ means it want to use the standard c++ library. check you've got libstdc++ installed on your system.

Thanks acid

OK... Now I got gcc version 2.95, it seems it was the problem.
Guess what...

./configure ------>no problem
make --------->After 10 min of compilation I got this error:

What is this????
