Error compiling KDevelop-1.0beta3

[holle at almaden.ibm.com]

Your first errors seem to be related to runtimr type information (rtti) and can
be "solved" by adding -fno-rtti to the gcc compiler switches.

The second (config) error:
---
ltconfig:2099: g++ -o conftest -O2 -Wall -fno-builtin -fno-rtti
-fno-exceptions   conftest.c  1>&5
/tmp/ccaMaWwT.o: In function `main':
/tmp/ccaMaWwT.o(.text+0x4): undefined reference to `dlopen(void)'
---
it is only missing the library called libdl.so whoch contains dlopen (try man
dlopen). Try to sneak in the switch -ldl

When configureing your project, do:
CFLAGS="-fno-rtti" CXXFLAGS="-fno-rtti" LDFLAGS="-ldl" ./configure <whatever
args you pass to configure>
This presets flags in the environment which, interesting enough, get used by
configure. The LDFLAGS could also be LFLAGS, I am not sure about that. But you
should see changes in the "Checking compiler" output and no complains about
missing dlopen anymore.

On the other hand. You might want to check what compiler you are using now and
then check if you compiled the libqt and libkde* with the **same** compiler. If
not, do this before attempting to put a e.g. pgcc-1.0.9 libqt and a gcc-2.8.1
project together. It does not always work.
If you still have your "old" compiler you can select which backend to use with
the -b and -V switches, to both the gcc as well as g++ . Please check man page
and directories under /usr/lib/gcc-lib for details . Then just use the variables
 described above and the -V and -b switches will be used by configure :-)

Hi,

"make" stops with the following error-message (excerpt):

config.log contains some errors concerning ltconfig:

ltconfig:2099: g++ -o conftest -O2 -Wall -fno-builtin -fno-rtti
-fno-exceptions   conftest.c  1>&5
/tmp/ccaMaWwT.o: In function `main':

collect2: ld returned 1 exit status
ltconfig: failed program was:
#line 2077 "ltconfig"

My system configuration:
Suse Linux 6.0
KDE 1.1.2
QT 1.44 with QTcombat

What´s going wrong?
Thank´s a lot for any tips.
