I found that it was straightforward to make medm work under lesstif.
The following

patch may suffice:

XtVaSetValues(items[i].widget,

XmNaccelerator, items[i].accelerator,

XmNacceleratorText, str,

Basically, the XmStringCreateLocalized function gets called with a NULL

argument from time to time. This is technically undefined according
to the

API, but allowed by openmotif and causes lesstif to segfault. The patch

simply substitutes an empty string for the NULL where necessary.
A caveat: I'm not a heavy medm user so YMMV....

Hello,
I am having a few difficulties compiling medm specifically on fedora

core 6. First I had to install the lesstif-devel to get missing header

files, then I change my CONFIG_SITE.linux-x86.linux86 and customize it

to my platform, then when I compile and I get conflicting
definition for

_XmDrawShadow which is declared as extern in /usr/include/Xm/XmDraw.h

and in .../medm/xc/Matrix.c. As a result, Matrix.c doesn't compile.

Bummer! Has anyone experienced this problem?
I tried to compile edm in place of medm.
Again I hit roadblocks on fc6.
I did not investigate the reason in depth.
But is there anything that I can use to visualize me PV on fc6 (i.e.
that is straight forward to compile) ?
I also remember reading a thread related to Motif support in future
linux versions. If I remember correctly motif was not going to be
supported any more. Is that true?
