今天集成声网native rtc-linux-server-sdk的时候，遇到报错：

Caused by: java.lang.UnsatisfiedLinkError: /usr/java/packages/lib/libbinding.so: libagora_rtc_sdk.so: cannot open shared object file: No such file or directory

解决方式

配置环境变量

代码语言：javascript复制

[root@dev ~]# vim ~/.bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/java/packages/lib

主要是

代码语言：javascript复制

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/java/packages/lib

这里的/usr/java/packages/lib就是放我们存放so文件的地方

代码语言：javascript复制

[root@dev lib]# ll /usr/java/packages/lib/
总用量 36392
-rwxr-xr-x 1 root root   143088 11月 17 15:10 agora_rtm.jar
-rwxr-xr-x 1 root root    60532 11月 17 15:10 authentication-2.0.0.jar
-rwxr-xr-x 1 root root   335042 11月 17 15:10 commons-codec-1.11.jar

-rwxr-xr-x 1 root root 17865952 11月 28 15:15 libagora_rtc_sdk.so
-rwxr-xr-x 1 root root 10569400 11月 17 15:10 libagora_rtm_sdk.so

-rwxr-xr-x 1 root root       34 11月 17 15:10 PLACEHOLDER

然后是这个文件/etc/ld.so.conf

代码语言：javascript复制

[root@dev lib]# vim /etc/ld.so.conf
include ld.so.conf.d/*.conf

/usr/java/packages/lib
[root@dev ldconfig

添加/usr/java/packages/lib到末尾

然后执行

代码语言：javascript复制

[root@dev lib]# ldconfig

directory file object root shared
