/But/ I've got a vague recollection that somebody else had problems
running on some router or other, which is one of the reasons why I
fired things up at the end of last year and did some careful builds. I
can't remember exactly where that one got to- I suggest that you look
back through the fpc-devel and fpc-pascal archive.
The compiler was 2.7.1 (trunk) as of about revision 23218. In practical
terms I'd suggest starting off with the current trunk from svn and only
trying an older revision if really necessary.
If these don't work for you then I think we need to work out what's
going wrong, in case it's a general OpenWRT thing.

I've sent these in a tarball. I trust that you will accept that if the
files arrive with the correct checksums that they've run successfully
for me here.
Apologies for the lousy threading but our gateway drops some messages.

Michael: Curious thing is that those binaries definitely ran here So
there's either something very odd with Qemu/Debian, or with OpenWRT- and
I know where I'd put my money.
Dennis: Transfer the binary back off the OpenWRT system to a development
system, being very careful to track the file to avoid any possible
confusion, and apply cksum to it to make sure it's not been corrupted in
transit. Then transfer any other binary (e.g. /bin/sh) off the OpenWRT
system and apply file to it, to see how it's described. Also listen to
Michael and others since they've done far more recent work on this than
I have, and if necessary take the trouble of getting more of the
toolchain onto the target system.
