I have 2 questions 1 for angstrom 1 for ubuntu

1. My angstrom distribution cant run java jre_6 i saw in previous
thread cacao is a substitution for java? but cacao doesnt seem to work
as well..

root@beagleboard:/home/beagle/cacao-0.99.4# ./
configure
checking build system type... armv7l-unknown-linux-
gnueabi
checking host system type... armv7l-unknown-linux-

checking whether to enable maintainer-specific portions of
Makefiles... no
configure: error: armv7l systems are not supported at this time

2. I'm also trying ubuntu on another card but i'm having some problems
as well even after doing chmod for the OMAP35x.bin file
serial as follows:

root@beagleboard:/home/ubuntu# ./create_sgx_package.sh
OMAP35x_Graphics_SDK_setuplinux_3_01_00_06.bin
found
OMAP35x_Graphics_SDK_setuplinux_3_01_00_06.bin needs to be
executable

running
OMAP35x_Graphics_SDK_setuplinux_3_01_00_06.bin

./create_sgx_package.sh: line 40: /home/ubuntu/
OMAP35x_Graphics_SDK_setuplinux_e
root@beagleboard:/home/ubuntu#

Thanks in advance!

Not going ^^^^ to work...

I need to add system checks to the create_sgx_package.sh script as it
can ONLY be run on x86... (the *.bin file is an x86 excutable)

So run again, on x86..

Regards,

Oh you just can't do it on the beagle, that "create_sgx_package.sh"
extracts the relevant bits from the SDK to be used on the beagle in an
arm environment..

You have installed rxtx compiled for Intel-32 architecture. While java
jars are identical, the native library will be different.
You need to either download Arm-specific build of the lib, or compile
yourself from sources (using cross-compiler on a PC, or compile on
BB).

opkg install librxtx-java librxtx-jni should work

Sorry, anyone knows how to do on a ubuntu distribution?
