Installing Java On Linux/MIPS

Slaanesh

I am trying to install java onto a linux machine running
a MIPS processor, I am having alot of trouble.

My knowledge of Linux is very little, I get passed the licensing agreement
when I execute the .bin java install file for the 1.5 jre. It starts unpacking
and then tells me that it cannot execute the bin !

I imagine that this is because it is a MIPS processor ? I was looking up
JVM's for MIPS and didn't really dig up much. It's a pain in the rocks !
Perl is working on the machine, but that would mean learning perl, gah.

Any ideas ?

You got the install from sun?
Then yeah, it's because it's a MIPS

Even the PowerPC gets neglected at times. You'll probably need to look for an open source version of the JVM. Which until apache get theirs running might be limited to an old blackdown version or kaffe, which definitely has a mips version with all that that involves.

This might be easier, gcj

Depends on what you need to do.

There should almost certainly be a free port of Sun Java for Linux on MIPS. Google for it.

Thanks lads,

I'll give that Kaffe a try.
Probably another stupid question but how do I install rpm files ? RPM is not
installed on this linux distro. Is it easy to install ?

What Linux distro are you using? Also what machine are you running and processor? An SGI?
Manufacturers site is a good place to look for info on software available?

Unfortunately SGI only have ports of Sun's JDK for IRIX on MIPS, not linux.

I do believe it's an au1100 MIPS processor. Can't even tell what distro of linux I'm using. The board is a custom made board with limited features. I'm trying to use what I can without having to avail of support for now.

You'll almost certainly have to compile kaffe or gcj for it. gcj tends to be more compatible.

Can you try

dmesg | more

If that doesn't work view
boot.msg in /var/log

Amongst the top lines should provide the kernel version, gcc version and distro name.
(suse debian redhat etc)

Based on that we should be able to suggest whether there is a package manager present on your system, apt, yast or whether you need to build rpm and other binarys that you want from source.

Might be more mips experienced bearded ones that can help on the unix forum, if you want to ask the mod to move the thread.

That's the ouput of the dmesg command. I tried installing GCC but I need lot's of other tools like make that I can't seem to install either because it doesn't recognise the platform ?

Ugh, this is dirty.

OK, you're using Debian, so the default package manager should be apt

http://olympus.het.brown.edu/doc/apt-dpkg-ref/apt-dpkg-ref.html

That means that you should be able to request a package, and apt should download all the dependencies.

e.g, assuming apt is set up correctly
apt-get install kaffe
apt-get install gcc
(assuming gcc isn't already installed)

is available

You can also list the packages that you have installed already.

Most debian mirrors have the mips packages including
http://ftp.ie.debian.org/debian

If it's not set up correctly then
http://www.debian.org/doc/manuals/apt-howto/ch-basico.en.html

I'm not a debian expert though, so the unix forum is the best place to get issues with apt sorted.
