Speaking as someone who is supporting Java/JNI of FreeBSD for a commercial app, putting JNI's into a path already named by ldconfig (/usr/local/lib, for example) has yielded the best results.

There is of course, the other option, which you took, of placing the library into a system directory which is searched for shared libraries as well. But in general you'll have to set up LD_LIBRARY_PATH to include the directory where your shared library resides. > but if I follow the compile instructions from the jni tutorial on > javasoft.com, it just doesn't work. I don't know what those instructions are off hand. You need to compile a shared library is the only requirement. If the JNI tutorial has appropriate instructions for doing so with gcc then you should be ok. It should be something like: gcc -o libhello.so -shared -fpic hello.c > The error I get is:"/usr/lib/libhello.so: unsupported file type > (libhello.so)" Determine if its actually a shared library. The 'file' command is your friend. E.g., # file /usr/lib/libc.so.4 /usr/lib/libc.so.4: ELF 32-bit LSB shared object, Intel 80386, version 1 (FreeBSD), stripped > Maybe I haven't compiled it properly, have any thoughts on that?
