[Freedos-kernel] Use of DJGPP under FreeDOS
Some time ago I submitted am error report for DOSEMU about problems running DJGPP port of GNU SED from configure scripts http://sourceforge.net/tracker/index.php?func=detailaid=1429741group_id=49784atid=457447 and also tracker for FreeDOS. It took me some time to build working FreeDOS kernel from CVS sources under DosEMU-1.4.0. The problem when GNU SED writes output file up to 2GB (when DOSEMU quits) now seems to be fixed. There is however another problems. touch.exe (from DJGPP fileutils) fails with an error message: touch: setting times of `foo': Input or output error (EIO) I don't however know whether it is a problem of FreeDOS kernel or one of it's interaction with DOSEMU-1.4.0.

Re: [Freedos-kernel] Use of DJGPP under FreeDOS
Hi Andris, I think Bart Oldeman recently fixed the GNU SED problem... Some time ago I submitted am error report for DOSEMU about problems running DJGPP port of GNU SED from configure scripts http://sourceforge.net/tracker/index.php?func=detailaid=1429741group_id=49784atid=457447 and also tracker for FreeDOS. It took me some time to build working FreeDOS kernel from CVS sources under DosEMU-1.4.0. Do you want to say that the CVS sources have a bug in the build scripts and you had to repair them first? Please explain. The problem when GNU SED writes output file up to 2GB (when DOSEMU quits) now seems to be fixed. I assume this is due to the fix by Bart :-). So does the old kernel www.coli.uni-saarland.de/~eric/stuff/soft/by-others/kernel2036-binary.zip have the SED problem and the CVS one fixes it? Please compare. touch.exe (from DJGPP fileutils) fails with an error message: touch: setting times of `foo': Input or output error (EIO) Please compare two cases: A Linux directory simulating a drive in DOSEMU and a diskimage simulating a drive in DOSEMU. There might also be a long file name problem, try $_lfn_support=(0) in your DOSEMU configuration file, and try touch FOO instead of touch foo... :-). Thanks!

Yes, it is fixed between May 1st and current CVS versions. touch.exe (from DJGPP fileutils) fails with an error message: touch: setting times of `foo': Input or output error (EIO) Please compare two cases: A Linux directory simulating a drive in DOSEMU and a diskimage simulating a drive in DOSEMU.

I am however I myself am interested only on system which support LFN. 'touch FOO' fails in exactly the same way. As far as debugging showed it is DJGPP's utime() (or more exactly DOS Fn 0x5705, which fails). I'm going to test under VMWare Server-1.0.2. It is perhaps more clean environment rather than DOSEMU in case when Linux directory is used for simulating drive. I'm not going however to install FreeDOS in real partition on HDD.

2007/05/01 CVS version did not compiled out of box. So this problem
has appeared after that.
This problem was fixed in SVN last weekend, not in CVS anymore.
It only happens with Borland compilers though, not with Open Watcom,
which is why it was there unnoticed.
Without LFN there is not such problem. I am however I myself am
interested only on system which support LFN.
'touch FOO' fails in exactly the same way. As far as debugging
showed it is DJGPP's utime() (or more exactly DOS Fn 0x5705, which
fails).
Yes exactly, it is DOSEMU not implementing 0x5705 (and al=4,6,7). So
last time you reported the GNU sed bug at the wrong place, and now
this bug again :)
Anyway, I attached a quick dirty DOSEMU patch (probably applies to
all fairly recent sources incl 1.4.0) that works around it. It does
not actually modify the access time (that is more work, as DOSEMU will
need to get code to associate the DOS handle with an SFT, and then
look up an index into a file descriptor array in that SFT if DOSEMU
owns it; I'll do that later) -- it just pretends the call succeeds.
