#11 Failed to build in Ubuntu on ARM device

[Maker]

We have an ARM Panda Box. The device has Ubuntu 10.10 installed.

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:

Buildfile: /home/tiliu/zhilib/jxgrabkey-0.3.2/JXGrabKey/Java/build.xml

Can you try to run jxgrabkey/trunk/misc/Ant/build.xml to build a release? It seems as if the libJXGrabKey.so was not compiled properly.

Also if it already compiled the file on your computer, it is funny taht it still tries to use
"/home/tiliu/zhilib/jxgrabkey-0.3.2/JXGrabKey/C++/dist/Release/GNU-Linux-x86/libJXGrabKey.so"
maybe the output dir changed to something like "GNU-Linux-ARM" and the path is just incorrect?

In JXGrabKeyTest.java, you will have to edit the line 18:
System.load(new File("../C++/dist/Release/GNU-Linux-x86/libJXGrabKey.so").getCanonicalPath());
to fix this.

Thanks for your quick comment, I will take a try tomorrow.

Works now, thanks.

ARM needs custom compilation, since I have no ARM device, users will have to build their own releases via the included ant build.xml
