Linux Java problems

[adinov 1]

Just downloaded the latest binary (/energia-0101E0009), and tried to run energia. After I set the working directory, the following error comes up and there is no GUI. What is wrong???

 

 

 

java.lang.UnsatisfiedLinkError: /home/ad/Desktop/energia-0101E0009/lib/librxtxSerial.so: /home/ad/Desktop/energia-0101E0009/lib/librxtxSerial.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) thrown while loading gnu.io.RXTXCommDriver

Are you by any chance running this on a machine with 64-bit Linux? I notice the error mentions "ELFCLASS32"...

[adinov 1]

Yes core2 duo = 64 bit

 

Is that the problem?!?!?!? Why?

[chibiace 46]

the build is 32bit i think.

 

if you have a copy of arduino that works you could try borrowing their librxtxSerial.so 

[adinov 1]

My java under /opt/java/64 

has

 

/opt/java/64/jre1.6.0_31

/opt/java/64/jre-6u31-linux-x64.bin

 

I can't see a 32 bit version anywhere!

 

Thanks for your help to sort this out!!

cd /home/ad/Desktop/energia-0101E0009/lib/

mv librxtxSerial.so librxtxSerial.so.orig

mv librxtxSerial64.so librxtxSerial.so

[adinov 1]

SOLVED!

 

So the problem was due to the default 32-bit librxtxSerial class (driver). Replacing it with the 64-bit version that was already supplied in /lib/, fixed the problem.

 

thanks to all that helped!!

Great that you got it working.
