Issues with using g++ and dynamic libraries

Hi Luca,

don't give up so quickly.

Let us take a look to the source of your code. Independant that you wanna to
build a library or not... ;-)

You have to build a C++ structure. I mean, you have to declare a class in a
classDoThis.hh file and to implement this class in a classDoThis.cc or
classDoThis.cpp. Then you can choose the g++ compiler.

regards.
Karim

Hi Luca,

I'll suggest to change the name main.c to main.cc (same with CC.c).

Note: The attached Makefile the name of the compiler is still gcc ;-).
Change it to g++.

regards.
Karim

Hi everybody !!

I have used gcc to open and run functions from a dll using the following
source code:

(See attached file: main.c) and the little shared dll object: (See attached
file: CC.c)

by using the following makefile: (See attached file: makefile)

and everything goes OK.

But when using g++ (e.g. running makefile using  'make COMPILER_NAME=g++')
the shared library results not being readable.

The gcc version I'm using is 3.3, installed on a previously running 2.96.

Can you help me ? What did I do wrong ?

            Luca Illengo
