I'm no compiler/linker expert, but when i wanted to do this sort of thing, what i did was create my shared objects with functions void _init(void) and void _fini(void) if you link the .so with -nostdlib then the init and fini functions will be called when the shared object is linked in. gcc -shared -nostdlib -o blah.so obj1.o obj2.o .... i'm not sure if this is the solution you are looking for, but it may be. -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
