Good afternoon,

I spent some days with this cool router and experimented with various firmware versions.

The "mission objective" is to get java working on this router.

I tried OpenWRT Kamikaze(no success with java, problems with USB flash, etc.) and Oleg's firmware. WL500gp-1.9.2.7-9.trx was problematic - usb flash was not working and also the package system seemed to be broken or something. Then I found out that the package repository has moved to http://code.google.com/p/wl500g/downloads/list .

I downloaded WL500gp-1.9.2.7-d-r893.trx and programmed the router with it. I also reformatted the usb flash to ext3 filesystem and mounted it correctly to /opt.

Then I finally managed to install jamvm successfuly:

jamvm_1.5.1-1_mipsel 100% |*******************************| 201k 00:00:00 ETA
Done.
Unpacking jamvm...Done.
Configuring jamvm...Done.

But, when I try to run jamvm, I get this:
/ # jamvm
/bin/sh: jamvm: not found

Could you please help me? I seem to be lost after about two weeks of fight..

Thank you very much!

Welcome to LQ. ..

Unpacking jamvm_1.5.1-1_mipsel.ipk :

tar xvf jamvm_1.5.1-1_mipsel.ipk
tar xvf data.tar.gz
.. reveals : /opt/bin/jamvm
.. which you would have seen by looking in /opt/
or by using 'ls -R /opt' or 'find /opt -name jamvm'.

So either use the command '/opt/bin/jamvm'
or add /opt/bin/ to your path.
.....

Good luck ! .. .. ..

Thanks for greeting
OK, I've already tried running jamvm with the full path - despite I have also $PATH set up correctly( )) ) - same problem:

I also tried fsck and file on a nearby notebook:

Thanks for help..

cd /opt/bin/

file jamvm
This is a MIPS binary, for use on the router ?
Together with some cross toolchain ?

What is your purpose of installing this file ?
.....

It's strange, because it's been installed from Oleg's repository for Asus 500gp with ipkg..
So do you think I could exchange the binary? What architecture would be proper?
Thank you..

I tried making a simple script(with only ls command, beeing executed via /bin/sh) in /opt/bin directory and run it successfully.. But running anything that's been installed via ipkg (also to this directory) ends with "file not found" error..

The purpose is to get java working on this router.
Anyway, I got the same problem after installing SableVM(abother Java Virtual Machine) and tree utility(I don't actually need tree, it was just to check if the package system installs everything correctly).

I tried if the sablevm executable is of the same type as an executable that is working for me now:

meee:/media/disk/bin# file sablevm
sablevm: ELF 32-bit LSB executable, MIPS, MIPS32 version 1 (SYSV), dynamically linked (uses shared libs), stripped

meee:/# file /media/disk/emil/busybox
/media/disk/emil/busybox: ELF 32-bit LSB executable, MIPS, MIPS32 version 1 (SYSV), dynamically linked (uses shared libs), stripped

meee:/# ldd /bin/df
linux-gate.so.1 => (0xb7ee6000)
libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb7d75000)
/lib/ld-linux.so.2 (0xb7ee7000)
meee:/# ldd /media/disk/bin/sablevm
ldd: exited with unknown exit code (126)

I would really appreciate any tip.. Thanks in advance..

I am finally able to run programs from /opt/bin:
I edited /etc/ipkg.conf and left there only
src opt http://ipkg.nslu2-linux.org/feeds/op...g/cross/stable.

After upgrading and installing ncurses (according to http://wl500g.info/showthread.php?t=9007) every binary installed in /opt/bin works now!!

There is said to be a problem with mixing binaries from differrent sources.

This solved it!

Now I have a minor problem with jikes compiler, it says it can not load libuClibc++.so.0. I need it to compile a test 'hello world' java program..
