[esp-r] Re: ESP-r installation on 64bit Linux machine (Francesco Frontini)

Some work-arounds for 64 bit.  Below there is mention of a 32 bit version of
prj and a 64 bit version of the simulator.  Remember that the assumed size
of real numbers 'may' be different - I would suggest to also use a 32 bit version
of the simulator if, for example shading was calculated with a 32 bit version
of ish.

It would be helpful to try running prj from within a debug environement
such as DDD on Cygwin so that it might be possible to isolate the
cause of the crash.  I regularly compile Cygwin on 32 bit (Windows 32 bit
even on a 64 bit machine) and it rarely faults when opening up a project.

I have not tried cygwin on a 64 bit version of windows so I cannot
confirm if it is sensitive.  Note that if you are compiling on Cygwin
with the GCC 4 series that it is, in many cases more sensitive than
the older g77 compiler on Cygwin.

I experienced the same problems with esp-r on a ubuntu 8.04. And I think it is
due to  GTK library problems on amd64. Now I compile esp-r on a 32 bit
machine and use it on the 64 bit workstation. The X11 version compiles
without problems on amd64 so actually I'm using the 32bit version for prj and
X11 64 bit version for bps, this not a problem since I'm using the program
mainly in scripts with text front end.
 I have problems with the GTK version in cygwin 1.7 too. prj starts correctly
but when I try to open a project it ends with
Segmentation fault (core dumped)
again the X11 version works just fine.
By the way I'm using esp-r version 11.8 but similar probles occour with
previous versions too.

Best regards

Marco
