Hi All,

---How do I tell the g++ linker that my libraries are shared objects?


1. I compile the library files as follows: g++ -c mylib.C
2. Then I want to create the shared object by: g++ -G -o libmylib.so mylib.o
   But -G is not supported by g++ anymore,
   it must be -shared so: g++ -shared -o libmylib.so mylib.o
3. But now when compiling a C++ program 'useMylib.C' and including the library
   as in: g++ -L. useMylib.C -lmylib
   I get an error: ld: -lmylib: No such file or directory
4. And when I rename libmylib.so to libmylib.a (which doesn't make sense but I
   had to do something) I get the error:
   collect2: dynamic dependency libmylib.so.0.0 not found

I would appreciate it if someone could give me the correct recipe for compiling
an s.o. library, and including it when compiling the actual C++ program.

I am using GNU C++ g++ 2.7.0  on SUN OS 4.1.3

The GNU C++ FAQ doesnt' help me, neither does the man page. I am also looking for
those famous 'manuals in the distribution' but can't find them. A related question
about the manual has been posted to the gnu g++ newsgroup.

Thanks a lot in advance,

Aryan.
