I'm getting lots of these ever since around when I switched to a
glibc mixed system (still has libc.5 and libc.4 on it with A.OUT and ELF
support):
Sep 3 20:20:09 Q facility=kern(0) priority=notice(5) kernel: N_TXTOFF < BLOCK_SIZE. Please convert binary.
ulmo@Q:~/src/memwatch-1.2$ egrep -c "N_TXTOFF < BLOCK_SIZE" /var/log/messages
1202
ulmo@Q:~/src/memwatch-1.2$ head -1 !$
head -1 /var/log/messages
Sep 3 10:54:19 Q facility=syslog(50) priority=info(6) syslogd 1.3-3: restart (remote reception).
ulmo@Q:~/src/memwatch-1.2$
I tried to trace them down many times, cumulitive for hours. Now I'm
looking at the kernel source:
ulmo@Q:/usr/src/linux$ egrep -e 'N_TXTOFF < BLOCK_SIZE' `find -type f ! -name '*~'`
./fs/binfmt_aout.c: printk(KERN_NOTICE "N_TXTOFF < BLOCK_SIZE. Please convert binary.\n");
./fs/binfmt_aout.c: printk("N_TXTOFF < BLOCK_SIZE. Please convert library\n");
./fs/binfmt_aout.o:<5>N_TXTOFF < BLOCK_SIZE. Please convert binary.
./fs/binfmt_aout.o:N_TXTOFF < BLOCK_SIZE. Please convert library
./fs/fs.o:<5>N_TXTOFF < BLOCK_SIZE. Please convert binary.
./fs/fs.o:N_TXTOFF < BLOCK_SIZE. Please convert library
./vmlinux:<5>N_TXTOFF < BLOCK_SIZE. Please convert binary.
./vmlinux:N_TXTOFF < BLOCK_SIZE. Please convert library
ulmo@Q:/usr/src/linux$ cd fs
ulmo@Q:/usr/src/linux/fs$ emacs binfmt_aout.c
Now I find out that there are lines close by where they know what the
inode # is! This is appaling! An error with no indication as to why!
I could not believe I wasted my time because of such a poor error
reporting, I assumed they could not say any clue.
Here's a patch to fix that, probably more important now, untested but
it compiles and looks right; I'm sure this better documentation should
be considered as a general case for Linux error reporting, but this
specific case might help a few people; if I find the problem, I'll
followup, and if it seems pertinent, I'll email to Linus to have him
add this into 2.0.31pre#9 so that all the glibc converters will know
what's going on:
