After some tweaking with the librxtxSerial.so lib I got a working arduino IDE for my yeeloong netbook. (They wrote arduino in java to be platform independent but included a 32bit i386 shared object lib without reference of its source?!) So to replicate this you will need the following packages:
avr-gcc, openjdk-6-jre, and avr-libc After installing those you will need to get rxtx lib from the archive (version 2.1-7).
This will need additional patching since newer kernel versions define UTS_VERSION in linux/utsrelease.h now instead of version.h. Also linux/io.h is now known as linux/uio.h. Furthermore you will need to add 1.6 to the configure.in / configure script:
--- 21611,21617 ----
TARGETLIB="\$(target_triplet)/librxtxSerial.la \
\$(target_triplet)/librxtxParallel.la"
case $JAVA_VERSION in
! 1.2*|1.3*|1.4*|1.5*|1.6*)
#fix_parameters $JPATH/jre/lib/javax.comm.properties
CLASSPATH=".:\$(TOP):\$(TOP)/src:"`find $JPATH/ -name RXTXcomm.jar |head -n1`
RXTX_PATH="\$(JPATH)/jre/lib/\$(OS_ARCH)"
(Taken from this email).
If you miss this step RXTX_PATH will not be set properly and you will get an obscure java.lang.UnsatisfiedLinkError:
gnu.io.RXTXCommDriver.nativeGetVersion()Ljava/lang/String; thrown while loading gnu.io.RXTXCommDriver
when starting arduino.
Now run configure, make and copy the librxtxSerial-2.1-7.so to your build/linux/work/lib directory. You will find this in mips64el-unknown-linux/.libs/ in your rxtx directory. Also copy the RXTXcomm.jar file.
After that run ./make.sh in the arduino/build/linux and maybe ./dist.sh and you will get a tarball with your arduino IDE! You can grab my copy here.
