Perhaps some part of the octave use the (stable) libstdc++.so.6.0.8 and some use the experimental library. You can try to remove the experimental library with: rpm -e libstdc++so7 and recompile octave. Since you are new to Linux, you find it probably easier to install the pre-compiled octave package included in Fedora extras:Alex, Thanks for your suggestion. I removed the libstdc++so7 package and then started all over with a fresh un-tarred directory, executing ./configure make make check Unfortunately, I again had the same problem, with the output as shown: src/DLD-FUNCTIONS/cellfun.cc ...........................

(Notice that I did the 'make check' before doing a 'make install'. I assume this is OK since I did not want to mess up my working version of Octave.)Fedora includes currently octave version 2.9.5.Yes, I know. I have been experimenting with it, but I really wanted to complete a successful build - just to make sure I know I am doing. Apparently, I do NOT know what I am doing, so I guess I will just have to move on to other things. Thanks very much for your help. If you do have any other suggestions, I would certainly welcome them. Bob
Please keep the discussion on octave-help mailing list.
I'm also using octave-2.9.6 on FC5 (but x86_64 not i386). I didn't run "make check" when I installed octave-2.9.6, but now after a "make check" I'm seeing the error in luinc.cc that you described as well. It seems to be related to the fact that UMFPACK is not installed:
error: UMFPACK not installed
panic: Segmentation fault -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Segmentation fault (core dumped)
Probably luinc should only be compiled if UMFPACK is installed. I copied David ( author of luinc.cc) in Cc to see what he thinks.
