[jnc-users] RXTXcomm and JNC

[Mario De W. <m.d...@ie...>]

Hi

I've almost built my opensource app 'BT747' using JNC after getting rid of
some unsupported method calls like String.format and
BufferedImage.getTransparency.
I am now at the final 'link'.  I've used Proguard to get rid of most of the
rest.

I get this kind of messages (I build using ant, so I use the autocompiler,
resulting in the '[exec prefixes]):
     [exec]
C:/xxx/workspace/BT747/lib/RXTXcomm-win.jar.o:RXTXcomm.jar:(.text+0xdf2):
undefined reference to `java::lang::String*
gnu::io::CommPortIdentifier::native_psmisc_report_owner(java::lang::String*)'
     [exec]
C:/xx/workspace/BT747/lib/RXTXcomm-win.jar.o:RXTXcomm.jar:(.text+0x26d4):
undefined reference to `void gnu::io::I2C::eventLoop()'
     [exec]
C:/xxx/workspace/BT747/lib/RXTXcomm-win.jar.o:RXTXcomm.jar:(.text+0x2bee):
undefined reference to `int gnu::io::I2C::open(java::lang::String*)'
     [exec]
C:/xxx/workspace/BT747/lib/RXTXcomm-win.jar.o:RXTXcomm.jar:(.text+0x2c52):
undefined reference to `void gnu::io::I2C::nativeSetI2CPortParams(int, int,
int, int)'

I've set the  java.library.path as this information line shows:
     [exec]
-Djava.library.path=lib;C:\xxx\workspace\BT747\lib\rxtx-2.1-7-bins-r2\Windows\i368-mingw32

I've tried both JNI and CNI.

Regarding the first link error, this is defined int he code as:
    private native String native_psmisc_report_owner(String PortName);


I'll look further and I'll probably find it, but if somebody has the anwser,
it will surely save some time.

Kind regads
