error loading dynamic library with Java

trutnev · 05-30-2005, 10:53 AM

Hello,

after compiling a dynamic library "test.so", i run java code loading that libarry and i get this message

Exception in thread "main" java.lang.UnsatisfiedLinkError: no test in java.library.path

i guess i should install test.so somewhere, but how and where.

thank you.

which java compiler are you using? Which VM?

obviously test.so should be installed in java.library.path, so examine that value (i.e. printf it).

it is 1.4.2_04 version (java -version). what do you mean - whar VM ? I'm very new to Java.

should i access java.library.path from C (because of printf). how can i do it.

you need to add the path to the "test.so" to your LD_LIBRARY_PATH environment variable.

Code:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<path to test.so>

it doesn't work. i also install my so in /usr/local/lib with /sbin/ldconfig. the same error

but for instance, i use "load()" function instead of "loadLibrary()". it loads the file and it is ok.

thanks anyway
