安装jzmq常见问题

1 出现java.lang.UnsatisfiedLinkError: /usr/local/lib/libjzmq.so.0.0.0: libzmq.so.1: cannot open shared object file: No such file or directory异常 
原因是未找到zmq动态链接库。 

解决方法1：export LD_LIBRARY_PATH=/usr/local/lib 
解决方法2：编辑/etc/ld.so.conf文件，增加一行：/usr/local/lib。再执行sudo ldconfig命令 
2 Exception in thread "main" java.lang.UnsatisfiedLinkError: no jzmq in java.library.path
未设置native library 
在eclipse设置native library为/usr/local/lib 
或在jvm增加参数 
-Djava.library.path=/usr/local/lib 
或在启动脚本中增加 
java -Djava.library.path=/usr/local/lib

3 找不到javah

sudo ln -s -f /usr/lib/jvm/jdk1.8.0_25/bin/jar

sudo ln -s -f /usr/lib/jvm/jdk1.8.0_25/bin/javah
