How to get the library to work on raspberry pi #22
Comments
Hi! By looking at your message I see |
Thank you for your feedback. This following is from the status report of the demo. Construction Exception: jpen.PenProvider$ConstructionException: jpen.provider.NativeLibraryLoader$LoadException: java.lang.UnsatisfiedLinkError: /home/.../jpen-2-150301/libjpen-2-4.so: /home/.../jpen-2-150301/libjpen-2-4.so: cannot open shared object file: No such file or directory (Possible cause: can't load IA 32 .so on a ARM platform)... |
Sounds like the same reason: the library is not compiled for ARM. It's either a 64 bit or a 32 bit desktop version. |
Maybe you can contact the author of this branch: Based on the comments a successful build for arm64 was built. |
Thank you @hamoid I will contact him. |
Thank you for this library.
I created an application with Processing 4 which gets stylus position, angle and pressure.
However, when launched on raspberry pi, the following error shows up despite having the library present.
jpen.provider.NativeLibraryLoader$4 run
INFO: loading JPen 2-150301 JNI library: jpen-2-4-x86_64 ...
jpen.provider.NativeLibraryLoader$4 logOnFail
INFO: jpen-2-4-x86_64 couldn't be loaded
jpen.provider.NativeLibraryLoader load
INFO: no suitable JNI library found
Because of this error, the stylus pressure show up as zeros when collected.
