I tested the mipseb helloworld provided by Mark (Thanks again) but the
result is the same as my own helloworld,
on running, the whole shell just froze.
I opened another ssh and "top" and see that the program is taking up 50%
of the cpu.
Also, I tried to /proc/cpuinfo and it even said Permission denied (I
have already chmod 777).
This OS does not even support the file command.
I am guess some rtl might be missing or some permission problem is
causing the freezing problem.
Any ideas?
On another note, my NetGear 3700v4 router is actually running DD-wrt
21286 (not Openwrt, I previously thought DD-wrt was a spin off of
openwrt, Sorry).

I need to know at this stage whether a FPC produced program compiled
for MIPS (big endian) can actually run on my hardware.
If that result is negative, I shall need a totally different approach.
I've just checked and I have big- and little-endian "Hello, World!"
programs natively-compiled that run on Debian Linux on Qemu. I can
send either or both if it would help, but I'd caution that they date
back to around Xmas last year and something /could/ have changed with
the compiler since.
Big endian (on appropriate system):
$ file test
test: ELF 32-bit MSB executable, MIPS, MIPS-II version 1 (SYSV),
statically linked, stripped
$ ./test
Hello, World!
Little endian (on appropriate system):
$ file test
test: ELF 32-bit LSB executable, MIPS, MIPS-II version 1 (SYSV),
statically linked, stripped
$ ./test
Hello, World!
/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.
Our gateway is dropping some messages due to attachments or something.

OK, you should have them but I would say that this isn't easy for me
at the moment: my host system is too slow to be realistic and booting
the two targets took around an hour.
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.
