"JNI : Linux java.lang.UnsatisfiedLinkError

846238Jun 6 2011 — edited Jun 6 2011
Hi All,



My bundles use JNI to communicate to the native code.

My native code further uses Sqlite3 libraries.



Please let me know how to link the the libraries:

Command I have used to generate the JNI shared library:

1.

gcc -I/java/jdk/include -I/java/jdk/include/genunix -c DbOperations.c -o DbOperations.o

ld -shared -f /usr/lib/libuuid.so DbOperations.o -o DbNativeInterface.so



2.

gcc -o libDbNativeInterface.so -shared -Wl,-soname,DbNativeInterface.so

-I /usr/lib/jvm/java-6-sun-1.6.0.22/include/

-I /usr/lib/jvm/java-6-sun-1.6.0.22/include/linux/ -I /<My path to>/SQLite/inc/ DbOperation.c



Using this so file in the bundle throws following error:

Couldn't start bundle: DataAccess (#22) (due to: java.lang.UnsatisfiedLinkError:

/home/user/knopflerfish_osgi_sdk_3.0.0/osgi/fwdir/bs/22/jar0/libDbNativeInterface.so:

/home/user/knopflerfish_osgi_sdk_3.0.0/osgi/fwdir/bs/22/jar0/libDbNativeInterface.so: undefined symbol: sqlite3_open)

java.lang.UnsatisfiedLinkError: /home/user/knopflerfish_osgi_sdk_3.0.0/osgi/fwdir/bs/22/jar0/libDbNativeInterface.so:

/home/user/knopflerfish_osgi_sdk_3.0.0/osgi/fwdir/bs/22/jar0/libDbNativeInterface.so: undefined symbol: sqlite3_open



Please guide with solutions or suggestions if any

Thank you

Vinay
