Running Sun 1.4.2 in 32-bit mode on the Opteron (Linux)

Hi there,

I have a dual Opteron running on Linux on which I'd like to run the
Sun 1.4.2 JVM (which is only available in 32-bit as of now). I know
Blackdown makes a 64-bit one, but Blackdown is not considered at the
moment.

Whenever we try to install the 32-bit JVM (i.e. the file
j2sdk-1_4_2_03-linux-i586.bin), it exits with an error:

--------------------------------------

tail: `-1' option is obsolete; use `-n 1'
Try `tail --help' for more information.
./j2re-1_4_2_03-linux-i586.bin: line 276: [: -lt: unary operator
expected
Unpacking...
tail: cannot open `+424' for reading: No such file or directory
Checksumming...
1
The download file appears to be corrupted. Please refer
to the Troubleshooting section of the Installation
Instructions on the download page for more information.
Please do not attempt to install this archive file.

--------------------------------------

Did anyone ever encounter this? Can anyone help?

THanks,

Phil

The file is a script. Open it in any editor and change the tail
command (there might be several). Alternatively, run tail yourself to
extract the zip file containing the sdk.

Something like this:

tail -n +424 ./j2re-1_4_2_03-linux-i586.bin > foo.zip
unzip foo.zip

Check the contents of the script to see what number (e.g. 424) to use.

It's probably easier to just set "_POSIX2_VERSION=199209". Ie. use
'_POSIX2_VERSION=199209 ./j2sdk-1_4_2_03-linux-i586.bin' on the command
line. Setting this variable to 199209 makes tail and friends accept
the obsolete options. (The problem is fixed in forthcoming Blackdown
and Sun releases.)

Just using 'tail ... > foo.zip ; unzip foo.zip' won't work because the
the jar files are packed in recent releases. If you're using this
solution, you'll have to unpack them manually after unzipping the file
with ./j2sdk1.4.2_03/lib/unpack.
