[esp-r] Re: prj: segmentation fault

[Lukas Swan (Dal)]

Hi:

I checked both suggestions- 75 and 100 dpi bitmap fonts are installed.

Then I compiled with ---debug support.

I ran the "prj" using the "gdb" program and it said:

 

(no debugging signals found)

Program received signal SIGSEGV, Segmentation fault.

0x00000000007db4b7 in f_exit ()

 

 

Does this mean anything to you Jon?

Thanks

Lukas Swan

A recent question about ESP-r and 64 bit compiling.....

 

I have just downloaded and compiled ESP-r on a FedoraCore 6 OS using g77.

It is a dual processor 64bit machine

When complied for GTK it works very well

When compiled for X11, and I run the command "prj" it briefly opens the
project manager window (<<1second) and then says "Segmentation fault" in my
terminal

This occurs for any of the binaries (e.g. "bps").

Any ideas?

 

I also am running it on a single processor 32bit machine with Fedora Core 6
and the X11 version works fine.

 

Testing is underway to ensure that ESP-r works on 64-bit computing
platforms.

At this point there are numerical issues with  64-bit environments which
have

yet to be resolved. There is not yet a consensus in the ESP-r development
community

to recommend using ESP-r on 64 bit platforms.

 

Previous posts have also talked about work underway to prove that the newest

GCC compilers (4.1.1 onwards) pass the validation tests.

 

It should be possible for someone who has a 64 bit platform to Install

esp-r with debugging on and to run the executable within a debugging
environment

such as gdb or ddd and track down the location where the segementation

falult is happening.
