dosemu-1.2.2

Hello.

Please attach your boot.log.

Here's more detail I have extracted from this. With 1.3.1, I can't print with hogthreshold at either 1 or 2. With 1.2.2, I can print with hog at 1 only if I switch back to the shell application that calls the app, and I can print with hog at 2 without having to switch back to the shell application at all.

With 1.3.1, if I attempt to kick off the printing by switching back to the shell application, I get this:

ralvy@libranet:~/dosemu-1.3.1/bin$ ./xdosemu

We'd like to see boot.log when DOSEMU has crashed, not when it has terminated normally.

Alternatively try
xdosemu -o logfile.txt
make it crash and send the contents of logfile.txt. Please make sure you have gdb installed.

Yes. I just realized that after attaching that boot.log. So I attached another one here, with the crash data in it.

Hi Ralph,

Stas did not only try to fix something, but also cleaned up. This cleaning up was problematic (note to Stas: fops.write can be either printer_write or stub_printer_write; printer_write is not a wrapper that calls the function pointer -- and *if* you're cleaning up you should change *that* and preferably in a seperate patch to make it easier for me to merge with -stable!)

Ralph, please revert Stas' patch using
patch -R < lpt.diff
(or by untarring the 1.3.1 or 1.2.2 source code) and then apply my patch (attached):

patch < lpt2.diff

and try again.

Bart

I untarred 1.3.1, did a ./configure, and then did

Here's what I get:

I'm not sure what to tell it at this point.

I mean, should that have been

patch -p0 < lpt2.diff

instead?

yes, sorry for forgetting that -p0.

Bart

Okay, I figured that after reading the patch man page, so went ahead and did

patch -p0 < lpt2.diff

on a configured 1.3.1 untarred source. After 'make' and 'make install' I find that I no longer crash like before, but I have the same problems previously outlined:

hogthreshold of 1 lets my cpu stay down, but won't let me print without
taking extraneous steps after issuing the print command.

hogthreshold of 2 keeps my cpu at about 86%, but lets the app's print
command yield immediate printing without extraneous steps.

Dumb question, but are you certain that you are running the new dosemu executable? Issue a 'which dosemu' to see which one the shell is running, and ls -l that file to ensure that the timestamp indicates that it is the freshly compiled one. It is possible that you have one sitting around e.g. both in /usr/bin and /usr/local/bin, or something like that.

I have the config file set to install in

        ~/dosemu-1.3.1

and I run xdosemu from

        ~/dosemu-1.3.1/bin

Simply typing

xdosemu

instead of

./xdosemu

from that directory yields nothing. So I don't have any stray dosemu occurrences being grabbed. My 1.2.1 and 1.2.2 versions are also all local installs.

And the splash screen that arises on loading, shows the correct version and configure date.

Should that have been

patch -p0 < lpt.diff

instead?
