Post by jankomEarthlinkHi Franta,
Not there yet... sorry.
Thanks for the links, I satisfied missing dependencies, did rpm install,
xfer_andraswd/Installedrpm-s/dosemu-1.4.0.8-git633.g3492afd.3.dbgemu.fc3.i686.rpm

"/usr/share/dosemu/Xfonts": error scanning
This was all from root. After issuing dosemu command system hung as in
many previous, earlier attempts. Ctr-c did not stop it. I ran again dosemu
from another xterm window with strace and it is stuck at the segmentation
fault.
So back to segmentation fault, where it probably started this entire thread.
(in parenthesis: "error scanning" is a strange message that I also get at
boot when starting x session, but everything seems OK there)
See my new posting to jegunn's message in the subject of segmentation fault.
Hi Janos,
sorry for the late reply. I'm not sure, when Your SIGSEGV DOSEMU crash
is caused by accessing to shm - Your strace seems normal. FYI, on my
FC3/i686/1GB RAM my strace in Your place is this:

2) Your error message: '"/usr/share/dosemu/Xfonts": error scanning'
is perhaps caused by fc-cache problem. What You obtain on command:
fc-cache -v -f /usr/share/dosemu/Xfonts
It should be successfull and in '/usr/share/dosemu/Xfonts' directory
should be created (empty) file 'fonts.cache-1'.
You should also verify dosemu RPM package right installation by cmd:
rpm -V dosemu
On my PC it produce only one line (which is OK):
.......T. /usr/share/dosemu/Xfonts/fonts.dir
Also, are You using xfs - X font server?
Maybe You have somehow broken Your system - e.g. missing some files
or directories, bad ownership or permissions on them etc.
You can verify it by 'rpm -Va' command. This should not produce any
serious problems (it is necessary assessed output individually).
3) Did You tried run dosemu in console and/or in Xterm in terminal
mode ('dosemu -t')? What is result?
