Compiler gcc

Compiler gcc

[Mathias Bordier]

Hello,

I want to create a dynamic library with the compiler
gcc.2.7.2.3 on Sun-Solaris.2.5 for C++ code.
I use JNI (Java Native Interface) for interfacing Java
and C++. I compile and I link for creating a dynamic
library (it's OK) and when I want to use this library,
I see the message:

ld.so.1: fatal: relocation error: file mylib.so:
symbol __builtin_new: refrenced symbol not found

I understand that the dynamic library I have created
is not good !

Maybe I have made an error when I compile or link my
program C++:

I have write:
for compiling: g++ -I ... -c mylib.cc
and 
for linking: g++ -shared -o mylib.so mylib.o -lstc++
-lg++

If you have an idea about my problem ????

Thanks

Try with -fPIC in order to produce position independent code.

I think you don't need to specify stdc++ (it's a typo in your command
isn't it?) and g++ library in this step - it doesn't hurt though.
