Dear Sirs, I have just built a new system and installed Redhat 7.3 Linux straight out of the box set. I installed all the available KDE/Gnome packages and appear to have everything up an running normally. I wanted to install xemacs for code development and writing latex so I downloaded the latest stable version 21.1.14 and followed all the build instructions. Originally I ran the configure script without any options since most appeared to be auto-detect and the last time I built xemacs on a linux system (about 3 years ago) everything worked fine doing this. Nothing bad was reported so I ran make install as root. This also ran free or any errors and I now have a executable /usr/local/bin/xemacs. I downloaded the efs and xemacs-base packages so that I could get xemacs to install it's own packages directly. I unpacked these into the recommended /usr/local/lib/xemacs/xemacs-packages directory and then proceded to run xemacs for the first time. Unfortunately, I can not run xemacs without it immediately crashing out reporting: Fatal error (11). Your files have been auto-saved. Use `M-x recover-session' to recover them. .... I seem to have core dumps inhibited on this linux installation and can not work out how to turn the facility back on. Please advise if you know how to do this and I will gladly provide more debug information. I have managed to run ddd on xemacs and it reports: Program received signal SIGSEGV, Segmentation fault. 0x4031070e in XtInitializeWidgetClass () from /usr/X11R6/lib/libXt.so.6 (gdb) I tried to change a couple of the configure options not least of which was --debug but the problem remains the same. Since I have never had any problems in the past building xemacs I am now at a loss for what to do next? Please advise accordingly. Regards Eddie Moxey. e.moxey(a)surrey.ac.uk
