UnsatisfiedLinkError: Unable to load library
The UnsatisfiedLinkError
occurs when the Java Virtual Machine (JVM) is unable to load a native library that your Java code is trying to access. This error commonly occurs when the library is missing, not accessible, or incompatible with the JVM.
To resolve the UnsatisfiedLinkError
, consider the following steps:
Check Library Path: Make sure the library is present in the correct directory or location. The library should be accessible by the JVM. Check the library file's permissions and ensure that it can be read and executed.
Verify Library Architecture: Ensure that the library matches the architecture (32-bit or 64-bit) of your JVM. If the library and JVM have mismatched architectures, you will encounter an
UnsatisfiedLinkError
. Make sure both are either 32-bit or 64-bit.Set Library Path: Set the
java.library.path
system property to include the directory where the library is located. You can set this property when launching your Java application using the-D
flag:javascriptjava -Djava.library.path=/path/to/library YourMainClass
Check Library Dependencies: If the library has dependencies on other native libraries, make sure those dependencies are also present and accessible by the JVM.
Verify Library Compatibility: Ensure that the library version you are using is compatible with the JVM version you are running. Incompatibilities between library versions and JVM versions can result in
UnsatisfiedLinkError
. Refer to the library's documentation or contact the library provider for compatibility information.Check Operating System Compatibility: Confirm that the library is compatible with your operating system. Some libraries may be specific to certain platforms, and attempting to load them on an incompatible platform can cause the
UnsatisfiedLinkError
.Recompile and Relink: If you have the source code for the library, recompile and relink it to ensure it is compatible with your system and JVM. This may involve adjusting build settings or dependencies.
By following these steps, you can troubleshoot and resolve the UnsatisfiedLinkError
related to loading native libraries in your Java application.
