java.lang.UnsatisfiedLinkError on 3.12.0+ #84

Hi,

I get an UnsatisfiedLinkError when running my application on Raspberry Pi, starting from 3.12.0.

java.lang.UnsatisfiedLinkError: gnu.io.RXTXCommDriver.nativeGetVersion()Ljava/lang/String; at gnu.io.RXTXCommDriver.nativeGetVersion(Native Method) at gnu.io.RXTXCommDriver.(RXTXCommDriver.java:105) at gnu.io.NRSerialPort.getAvailableSerialPorts(NRSerialPort.java:153) at se.lunderhage.pcr1000.backend.daemon.SerialPortUtils.getSerialPorts(SerialPortUtils.java:46) at ...

3.11.0 is the last version not having this problem, but there I can't use 38400 bps on the raspberry for some reason. (38400 works fine with minicom).

Will try to build the ARM binaries and see what happens...

Regards

Same issue here, I've tried building the ARM libraries and it didn't fix it. I can't test 3.11 however, as I need a karaf bundle.

False alert, I solved the issue by installing liblockdev1-dev. I don't know if it's possible to check for the presence of the lib and display a proper error message though.

The warning and conflict resolution would happen at the .deb packaging level. I just set myself up a new PPA, so ill look into bundling up this jar and making a system lib perhaps? It would require a lot more discussion in any case
