greetings,
I need a little assistance with building a shared library for JNI under
Linux 2.2.
This is how I went about creating the library:
compiling: g++ -I /usr/local/java/include
-I/usr/local/java/include/linux -shared -fPIC -o keys.o keys.c
linking: gcc -shared -Wl,-soname,libkeys.so -o libkeys.so.0 keys.o -lc
$ java -Djava.library.path=/home/ams/work/keys T
Exception in thread "main" java.lang.UnsatisfiedLinkError:
/home/ams/work/keys/libkeys.so: keys.o: cannot open shared object file: No such file
or directory
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1357)
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1281)
at java.lang.Runtime.loadLibrary0(Runtime.java:469)
at java.lang.System.loadLibrary(System.java:774)
at T.<clinit>(T.java:5)
I have also tried another way of building the library (ld -G -f
/lib/libuuid.so.1 keys.o -o libkeys.so) but got the same error. I have
to mention that the native code accesses the libdb.so library which i
copied to /home/ams/work/keys. Why doesn't java find my library? TIA,
-a
