Fedora 现在使用(包已安装Package rxtx-2.2-0.5.20100211.fc15.i686 already installed and latest version
)。
我已经使用/尝试过:
# locate librxtxSerial
/home/sun/Downloads/rxtx-2.1-7-bins-r2/Linux/i686-unknown-linux-gnu/librxtxSerial.so
/home/sun/Downloads/rxtx-2.1-7-bins-r2/Linux/ia64-unkown-linux-gnu/librxtxSerial.so
/home/sun/Downloads/rxtx-2.1-7-bins-r2/Linux/x86_64-unknown-linux-gnu/librxtxSerial.so
/home/sun/Downloads/rxtx-2.1-7-bins-r2/Mac_OS_X/librxtxSerial.jnilib
/home/sun/Downloads/rxtx-2.1-7-bins-r2/Solaris/sparc-solaris/sparc32-sun-solaris2.8/librxtxSerial-2.1-7.so
/home/sun/Downloads/rxtx-2.1-7-bins-r2/Solaris/sparc-solaris/sparc32-sun-solaris2.8/librxtxSerial.so
/home/sun/Downloads/rxtx-2.1-7-bins-r2/Solaris/sparc-solaris/sparc64-sun-solaris2.8/librxtxSerial-2.1-7.so
/home/sun/Downloads/rxtx-2.1-7-bins-r2/Solaris/sparc-solaris/sparc64-sun-solaris2.8/librxtxSerial.so
/usr/lib/rxtx/librxtxSerial-2.2pre1.so
/usr/lib/rxtx/librxtxSerial.so
然后使用:
-Djava.library.path=/usr/lib/rxtx/librxtxSerial.so -Djava.library.path=/usr/lib/jni
但我仍然得到以下信息:
java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path thrown while loading gnu.io.RXTXCommDriver
Exception in thread "main" java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path

at main.Tty.sendCommand1(Tty.java:212)
at main.Tty.main(Tty.java:236)
如何解决这个问题?
跟进:
错误的:
-Djava.library.path=/usr/lib/rxtx -Djava.library.path=/usr/lib/jni
正确的
-Djava.library.path=/usr/lib/jni -Djava.library.path=/usr/lib/rxtx
