Paul, You may verify if your Linux distribution has core dumping enabled:

# ulimit -c unlimited

and check if the directory where the VM resides is writeable. Once you run again the VM and see "Segmentation fault (core dumped)", You may search the dumped core with "file core" and run a gdb on it:

$ gdb squeakvm core

Inside gdb, the bt command will display a stack trace to see or mail out detailed information about your SIGSEGV. Cheers,

Hern?n

Hi -

Has anyone successfully run a newer version of Pharo on either Ubuntu 9.04 or Ubuntu 9.10 64 bit server? When I try to start the command line simply says "Segmentation fault" and does not emit a stack trace. The UUIDPlugin is named UUIDPlugin.bak. I am attempting to use the latest versions of pharo, pharo sources and both the pharo vm or squeak 3.11 vm from the pharo-project.org site. I have installed ia32-libs and I do know that the latest pharo runs on Ubuntu Desktop 9.04.

If you have gotten it running, will you please send me the output of

dkpg -l

or a description of whatever you did to get it started? Thanks

Also, I'd be happy to attempt other solutions or provide more information as I've tried what I know how to do and checked what I know to check.

Thanks

Paul
