1594.0. "X Toolit Warning followed by core dump?" by TENERE::SILVA (Carl Silva - Telecom Eng - DTN 828-5339) Thu Oct 03 1991 14:30

	Has anyone ever seen this message:

X Toolkit Warning: No type converter registered for 'String' to 'Pixmap' conversion
This is displayed 3 times and then pid 1787 (mcc_iconic_map_pm) was killed on an unaligned access, at pc 0x614ddc
Exception: Invalid memory address
IOT trap

	Its killing me.

Carl,

I have seen other X Toolkit Warnings, but never that one.

What are the circumstances under which it is received?  Does it occur each time
these circumstances are met?

Although all Xlib calls are supposed to be re-entrant, we are finding that
they are not and have been adding jackets as needed.

	It appears that the mcc_resource.dat file was missing from my
directory.

Carl,

It should not matter if you do not have the resource file locally, BUT there
should always be a copy of the resource file when the kit is installed, in
/usr/lib/X11/app-defaults/mcc_resource.dat.

Were you missing the system copy or the user copy?

The system copy defaults to the above, the user copy defaults to your login
directory. Either can be overridden by setting the environment variables
MCC_DECW_SYS_DEF and MCC_DECW_USR_DEF.

>Were you missing the system copy or the user copy?

	I was missing a user copy with MCC_DECW_USR_DEF set.  But my problem
was that I was also using a variable called XENVIRONMENT and mcc could not find
the normal defaults that it uses.  Sorry my fault but something to watch out
for.
