UnsatisifiedLinkError Java

flyz

Hi I'm getting the following error when I'm trying to load a library into my Java Application

<edit> I'm running it on solaris too and using jbuilder6 </edit>

It's complaining a bout the symbol __gxx_personality_v0.
The library compiles perfectly with no error

java.lang.UnsatisfiedLinkError: /export/home/java_dev/solaris/libiolayer.so: ld.so.1:

/opt/JBuilder6/jdk1.3.1/bin/../bin/sparc/native_threads/java: fatal: relocation error: file /export/home/java_dev/solaris/libiolayer.so: symbol __gxx_personality_v0: referenced symbol not found
at java.lang.ClassLoader$NativeLibrary.load(Native Method)

grrrrrrrrrrrrr

Looks like your trying to make a Native call to something that doesn't exist or you don't have rights to?

Quick check of google...

2.10 Why do I get the java.lang.UnsatisfiedLinkError when I run my Java program containing Native Method invocations?
A. Your program is not able to find your shared library or DLL.

On Windows 95/NT, make sure that the DLL exists in a path that is
included within the PATH environment variable.

On Solaris, make sure that the environment variable
LD_LIBRARY_PATH includes the path of your shared library.

I have rights to it and it does exist.

my problem is that i seem to get a linker error from my library

/opt/JBuilder6/jdk1.3.1/bin/../bin/sparc/native_threads/java: fatal: relocation error: file /export/home/java_dev/solaris/libiolayer.so: symbol __gxx_personality_v0: referenced symbol not found

Is export/home/java_dev/solaris/libiolayer.so on the library path?? type echo $LD_LIBRARY_PATH and ensure that that directory is on the path otherwise the linker and library loader will not be able to find it. You may have to change the properties of the project within jbuilder to add it if you are running it from within jbuilder.

Yeah it is.

I think I've fixed it though, I'd forgotten to put -shared in the compile line
