默认情况下在哪里安装本地Java库？

Question

I'm integrating JNI bindings with a C++ library.

The library follows the usual conventions: the installation root is /usr/local by default and can be modified with the --prefix argument to ./configure ; the .a or .so files go in ${prefix}/lib ; etc.

The JNI binding produces two new libraries, libfoojni.so (the native part) and libfoo.jar (the Java part).

Under this scheme, what is conventional place to put these files (eg ${prefix}/java )?

Is it preferable to allow the user to supply a separate Java root directory (eg, /usr/share/java )?

Should libfoojni.so go in ${prefix}/lib or in some Java-specific sub-directory?

Answer 1

When I've done JNI in the past on Linux, I've bundled the .so files with the application in a specific directory for JNI libraries. Then add this to the LD_LIBRARY_PATH environment variable for the JVM instance running the application.

So I would say that there isn't really a convention on this (besides the Linux lib directories for system wide stuff).

Hope that helps.
