Hi Trygve!
Very interesting, you are not using SWIG as part of your JNI karma.
Why did you move away from it?
I checked out your git javax-sb-libusb1 tree. I got it to compile, but
ran into 32/64 bit issues. I resolved them at the compile phase, but
then got strange runtime errors. such as these;
FATAL ERROR in native method: Field type (instance) mismatch in JNI
get/set field operations
at javalibusb1.libusb1.set_debug(Native Method)
at javalibusb1.Libusb1UsbServices.<init>(Libusb1UsbServices.java:77)
at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native
Method)
at
sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57)
at
sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45)
...
Any ideas?
