Has anybody done a port of strace for linux/mips 2.4??? I'm trying to 
debug something and need something simple.

strace is included in the MontaVista HHL distribution.  You can find the rpm
and srpm under ftp.mvista.com/pub/CDK?? and/or ftp.mvista.com/pub/area51.

There is a debian package of strace for mips in
ftp://ftp.rfc822.org/pub/local/debian-mips/packages/. It is working
with linux 2.4.

 I mean patches for MIPS, of course.  Strace 4.2 does not work for MIPS
out of the box.  The proper source still appears to be
http://www.liacs.nl/~wichert/strace/, BTW.

Wiggy somewhen gave me write access to the strace source some time ago, so
I assume that the stuff on sourceforge is now the official CVS.  For MIPS
I was using some CVS snapshot which was working for me out of the box
after I checked in some fixes.  But that's again already some time ago,
things may have changed since then.

 Well, here is most of the information available from the site...

                 Welcome to http://strace.sourceforge.net/

      We're Sorry but this Project hasn't yet uploaded their personal
                                webpage yet.
          Please check back soon for updates or visit SourceForge

 Where is the CVS you refer to?  A working strace would help me a lot.

Hmm, I guess I should fix that :)

I've started looking at strace again after not having had any time for
it in a while, and strace 4.3 should appear in a week or so. If there
are any problems with the MIPS support now is the time to tell me.
I'm especially interesting in strace reporting umoven() errors while
tracing a program.

Do you happen to know if those have any patches that are not already in
CVS?

Conincidentally I today built strace-cvs for MIPS before receiving your
message and found it to be working just fine.  The only bug which my
last several month old build from an older snapshot doesn't have is
that syscall 4129 (from memory, number may be incorrect) gets decoded
as a syscall with very many arguments (~ 20).  Will have to look into
it.

Good!

Hmm, 4129 is delete_module, which is handled exactly like sys_chdir
(syscal with one string argument). Looking at the syscall table I
can't find any syscall with that many argument, the highest number
I can find is 6 (mmap, recvfrom and sendto).

I wonder whether it is my sillines, or something is wrong with strace or
my mips tools. Checked out clean version from
cvs.strace.sourceforge.net:/cvsroot/strace, run configure "NATIVELY" on
mips32 system and got a whole bunch of errors on strace.c :

I've used glibc 2.1.95.
