Ubuntu on ARM device: problems building libJXGrabKey

Asked by Jerry Liu

We have an ARM Panda Box. The device has Ubuntu 10.10 installed.
We build Sikuli from source code on it. When launch, the following error occurs:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/tiliu/Sikuli-X-1.0rc2-linux/Sikuli-IDE/libs/libJXGrabKey.so: /home/tiliu/Sikuli-X-1.0rc2-linux/Sikuli-IDE/libs/libJXGrabKey.so: cannot open shared object file: No such file or directory (Possible cause: can't load IA 32-bit .so on a ARM-bit platform)

 at org.sikuli.ide.SikuliIDE.getInstance(SikuliIDE.java:130)
 at org.sikuli.ide.SikuliIDE.main(SikuliIDE.java:913)

Then we download source code of libJXGrabKey from http://anonscm.debian.org/gitweb/?p=collab-maint/jxgrabkey.git;a=summary, and re-build it on the ARM device. It brings us another error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/tiliu/Sikuli-X-1.0rc3-linux-armv7l/Sikuli-IDE/libs/libJXGrabKey.so: /home/tiliu/Sikuli-X-1.0rc3-linux-armv7l/Sikuli-IDE/libs/libJXGrabKey.so: undefined symbol: _ZTVSt19basic_ostringstreamIcSt11char_traitsIcESaIcEE

 at org.sikuli.ide.SikuliIDE.getInstance(SikuliIDE.java:135)
 at org.sikuli.ide.SikuliIDE.main(SikuliIDE.java:918)

So we are blocked here. Could you please let us know how to get Sikuli work on the ARM device?
It may also be helpful if you could provide us the source code of libJXGrabKey you use to build Sikuli.

Thank you very much.
Jerry

The original source is available here: http://sourceforge.net/projects/jxgrabkey/

Sikuli uses the latest version.

The problem might be, that you have to build the jar AND the native libs.

We get the latest version jxgrabkey-0.3.2 from http://sourceforge.net/projects/jxgrabkey/.
But when we build the jar, it brings us the following error:

Might be better to look for a solution in the net elsewhere (Ubuntu, ARM based systems, ...)

It works in the ARM Panda Box now.

Congratulations

and what was the solution?
