Solved: Core 4.7.7 under Qemu on Win7

[Lee]

I'm running Core 4.7.7 under Qemu on a 32 bit Win7 Pro system and I'm having trouble loading Xprogs.tcz.

Xlibs.tcz, Xprogs.tcz, Xvesa.tcz, wbar.tcz and jwm.tcz are all listed in onboot.lst but Xprogs fails to load.

If I try to tce-load -i Xprogs.tcz it tries for about five minutes then segfaults.

If I manually loop-mount the extension, copy the contents to the right places and run /usr/local/tce.installed/Xprogs I can get an X desktop.

When I do the copy from the extension to the main fs, it bitches about /usr/local/share/pixmaps/screenshot.png, ...services.png and ...settime.png not found.  I note that, in the extension, those files are symlinks and ls -l shows them in red (broken link?).

I have verified that this is the same Xprogs.tcz (by md5sum) that works fine on my real hardware, though I have re-downloaded it anyway.

Any ideas what might be going on?


Qemu batch file:

Code: [Select]

@ECHO OFF
SET SDL_VIDEODRIVER=windib
SET QEMU_AUDIO_DRV=dsound
SET QEMU_AUDIO_LOG_TO_MONITOR=0
start qemu.exe -L . -m 128 -hda tc477.img -boot c -soundhw sb16,es1370 -localtime -M pc

grub4dos boot entry:

Code: [Select]

find --set-root /boot/grub/tc477.img
kernel /boot/core4.7.7/vmlinuz quiet tce=LABEL=tc477.img/boot/core4.7.7/tce multivt text noautologin
initrd /boot/core4.7.7/core.gz

Edit: fixed typo in tce=LABEL=.... lee

tce-LABEL ?
Just make sure your tce directory is in the root of your disk image.

Double-check the dep files, a tce-load segfault is usually an infinite loop of dep files loading each other.

tce-LABEL ?

Sorry - that was a typo in the forum post - I can't seem to copy and paste from the vm window to a host app - but the running system has it correct (the tce directory is being found and other extensions loaded).

Double-check the dep files

Thanks Curaga - but no luck.  Xprogs depends on  Xlibs and fltk-1.1.10 but neither of those has a .dep file.

Tried different RAM sizes?  How much RAM in the physical machine?  Any errors on the physical machine (ie HDD "stalling" trying to perform a read)?  QEMU version?  Using VT-x/AMD-V?

I have it set to 128 MB of ram for the VM since I'm not doing anything memory intensive with it.  The physical host has plenty of RAM, but then it -is- running Windows...

In any case, the problem is solved, Curaga -rocks- and I'm feeling like a noob...

After restarting the VM (with more RAM, trying out Genec's idea), I rechecked everything and found that Xprogs.tcz.dep does not list  fltk-1.1.10.tcz  and  Xlibs.tcz  as I previously said.  It actually lists  fltk-1.1.10.tcz  and  Xprogs.tcz  - leading to a dpendency loop just as Curaga suspected.  I must have seen what I expected to see rather than what was actually there when I checked earlier.


Edit: Yeah, but now I feel like a -hero- noob.  That was kind of an anticlimactic 500th post.
