Thanks for the testcase. I think the error is in your makefile: ld -shared -soname libHelloWorld.so.1 -o libHelloWorld.so.1 HelloWorld.o You mustn't invoke "ld" directly to build a shared library. Instead, you should use gcc like this: gcc -shared -Wl,-soname -Wl,libHelloWorld.so.1 -o libHelloWorld.so.1 HelloWorld.o With that change, your example program seems to work fine. p. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
