java.lang.UnsatisfiedLinkError：加载gnu.io.RXTXCommDriver时抛出的java.library.path中没有rxtxSerial

现在使用Fedora（已安装Package rxtx-2.2-0.5.20100211.fc15.i686 already installed and latest version ）。 我用过/试过了： # 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 但我仍然总是这样： 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 java.lang.ClassLoader.loadLibrary(ClassLoader.java:1681) at java.lang.Runtime.loadLibrary0(Runtime.java:840) at java.lang.System.loadLibrary(System.java:1047) at gnu.io.CommPortIdentifier.(CommPortIdentifier.java:83) at main.Tty.sendCommand1(Tty.java:212) at […]
