Hi.
I'm running into some problems converting a Java library (i.e., .jar
file) into a native shared library (i.e., .so file) and then using that
library with g++. In particular, I have a native method in the .jar file
that I can't figure out how to define to the linker's satisfaction. I'm
using GCC 4.1.2 on Linux.
If I modify the gcjh-generated header file and define the native method
inline (e.g., virtual void receive(JArray< jbyte > *, jint) {} ) the
linker still complains about an undefined reference for the native
method:
.//libricochet.so: undefined reference to `void
multishot::examples::RicochetApp::receive(JArray<char>*, int)'
collect2: ld returned 1 exit status
If I define the native method outside of the header file (e.g., in a C++
source file like so:
void multishot::examples::RicochetApp::receive(JArray< jbyte > *, jint)
{} ) then the linker complains about a hidden symbol:
/usr/bin/ld: RicochetApp: hidden symbol `void
multishot::examples::RicochetApp::receive(JArray<char>*, int)'
in .obj/RicochetAppMain.o is referenced by DSO
/usr/bin/ld: final link failed: Nonrepresentable section on output
Any ideas as to what I need to do to rectify my problem would be greatly
appreciated.
Thanks!
