the -fexception problem is well known... and I will cc: your mail again 
to the kdevelop-devel-list to underline the urgency. I talked to Ralf 
Nolden to discuss this, but I cannot promise that we solve this until 
the next beta-release.

Here the manual way to solve this problem:

The following explanation is for all known project types, except the 
custom and the plain-c one (of course):
You have to modify configure.in.in (in the top_level project directory). 
If there is no configure.in.in you have to modify the configure.in.

First search inside this file the AC_CHECK_COMPILERS() macro call. If 
you found it you should the following line:
CXXFLAGS="$CXXFLAGS $USE_EXCEPTIONS"
afterwards.

If there is no AC_CHECK_COMPILERS() then configure.in.in it begins like:
#MIN_CONFIG

and you can add the line after the AM_INIT_AUTOMAKE() call (mostly the 
end of the file).

After that you should do "Build->Automake/autoconf" and 
"Build->Configure" (only to be on the save side) and it should work.
