Why do errors occur when compiling the Agora Signaling Linux Java SDK?

Problem​

The following error occurs when compiling the Agora Signaling Linux Java SDK in Linux:


_1
Exception in thread “main” java.lang.UnsatisfiedLinkError:no agora_rtm_sdk in java.library.path

Reason​

The agora_rtm_sdk library is not included in the environment variable.

Solution​

You can use one of the following solutions to solve this problem. For either solution, you must replace <path> with the absolute path to the Signaling Linux Java SDK.

Update environment variables​

Add the following line to any file that configures Linux environment variables, such as ~/.bashrc, ~/bash_profile, or /etc/profile.


_1
export LD_LIBRARY_PATH=<path>/agora/rtm/sdk:$LD_LIBRARY_PATH

Update Java command line arguments​

You can launch Java with the Djava.library.path argument to add the absolute path to the Signaling Linux Java SDK to the library path:


_1
java -Djava.library.path=<path>/agora/rtm/sdk
