JNI debugging, "error while loading shared libraries"

JNI debugging, "error while loading shared libraries"

[William Croft]

I'd like to use insight to debug our Java JNI native functions, written in C. 
  A very tiny test program (below), runs fine without insight ("java hi" from 
the shell).

public class hi {
	public static void main(String[] args) {
		System.out.println("hello world");
	}
}

But firing up java with insight (the java wrapper looks at export 
DEBUG_PROG=gdb), gets the following error as soon as I "run hi" from the gdb 
console:

/usr/share/jbuilder5/jdk1.3/bin/i386/native_threads/java: error while loading 
shared libraries: libhpi.so: cannot load shared object file: No such file or 
directory

----

Do you have any ideas or workarounds?  I put a "sh -x" on the java wrapper and 
it IS setting up LD_LIBRARY_PATH correctly.  Otherwise it wouldnt work in the 
case without insight.  I even tried manually adding the java libdirs to 
/etc/ld.so.conf, that didnt work either.

I'm running insight+dejagnu-20010703

BTW, I get the same failure from insight in "-nw" no windows mode.  And from 
gdb 5.0rh-5.  The OS here is RH7.1.

Thanks for your ideas.

Try `set env LD_LIBRARY_PATH ...' from the console before running the
inferior.

Sounds like a generic gdb bug, probably unconnected to Insight.
Perhaps the gdb list would be a better choice.
