[Dev-C++] undefined reference problem

[mohamad c. <moh...@in...>]

Hi all,
I'm new to g++. I'm trying to use a new library for linear algebra=20
called Lapack++, the problem is when I include this library into a=20
source file I get errors of kinds "undefined refernce". for example this=20
little and stupid code:
#define LA_COMPLEX_SUPPORT
#include <lapack++.h> // the new library
#include <iostream>
int main()
{
   LaGenMatDouble A ; // this uses the new library=20
   std::cout<< "This is a test  "<< std::endl;
   return 0;
}
the erros are like:
/tmp/cc2YU0wo.o(.text+0x19): In function `main':
undefined reference to =AB LaGenMatDouble::LaGenMatDouble[in-charge]()=BB

What could be the problem?
Please give me some feddback.
thanks in advance

The problem is that it isn't enough to add an include file to your source.
You must also add the corresponding library file (libXX.a) to the project.
Specify -libXX in the linker options.

[Dev-C++] help about automake and autoconf

[mohamad c. <moh...@in...>]

Hi,
I search some tutorials to begin building projects over j++, precisely  
i need to learn about autoconf, automake and which macro language we use 
to edit configure.in and Makefile.am. Can anybody guide me to some 
useful tutorials about these topics?
Thanks in adavance

Hi Mohamad,
 
Just use Google for 'tutorial c++ x', where x is autoconf, automake, etc.  You should be able to find what you want on-line.
