I think you can look here
ftp://ftp.ics.com/openmotif/2.3/2.3.1/
and install the .fc9 version, it should also work on fedora 10.

I found openmotif on rpm.pbone.net. In fact they have the fc10_x86_64 version there too & it seemed to install perfectly. However, I never found out if it works OK with my old motif code because, at the same time, I installed a graphics accel card & it appears to not be accessible to motif calls. I know there's a lower level x11 layer, but all I know is that my first call using -

main_window = XtVaCreateManagedWidget("main_window",
xmMainWindowWidgetClass, toplevel,
XmNwidth, Resrcs.width,
XmNheight, Resrcs.height,
NULL);

bombs the program (vc_GP). The only error message I get is the following -

[GP_home]$ vc_GP
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 19 (X_DeleteProperty)
Resource id in failed request: 0x0
Serial number of failed request: 94
Current serial number in output stream: 106
[GP_home]$

which I've heard means the x server isn't responding. Does anyone know what might be happening? Is it possible that "openmotif-2.3.0-0.3.fc10.ccrma.x86_64.rpm" doesn't really have 64 bit libs? Maybe I better compile my own from source. What say, anyone?

In short time packages with openmotif 2.3.2 for Fedora10_x86_64 will be uploaded on ftp://ftp.ics.com/openmotif
Try this packages, probably it will help for you.
In other hand you can download now openmotif 2.3.1 for Fedora9. I think it should work nice.

I tried your suggestion of installing the fc9 version of openmotif-devel 2.3.1, however, the result was the same. My old motif code (vc_GP.c) compiled fine. On execution, it ran fine up to the statement -

main_window = XtVaCreateManagedWidget("main_window",
xmMainWindowWidgetClass, toplevel,
XmNwidth, Resrcs.width,
XmNheight, Resrcs.height,
NULL);

at which point it bombs with the message:

X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 19 (X_DeleteProperty)
Resource id in failed request: 0x0
Serial number of failed request: 94
Current serial number in output stream: 106
