forum.alglib.net

I'm new here and trying to make use of alglib.
The alg.net told me 'Adding ALGLIB to your project is easy - just pick packages you need and... add them to your project!!"
But I can't compile even a simplest example:
"
#include<stdio.h>
#include<iostream>
#include "specialfunctions.h"
#include "specialfunctions.cpp"

using namespace std;

int main () {

const double x = 2;
double y = alglib::besselj0(x);

cout << y << "\n";

return 0;
"
I got the errors:
"
undefined reference to `alglib_impl::namesoffunctions.
..
..
..
..
"
is there anyone who can help me ?

I first find this when i compile my codes (which could be successfully done under visual studio in Win7) under ubuntu with g++4.5.2.
So I write a simple test but still get only errors. I' have visited sevaral webs for this problem, and someone told me I should not only include .h but also .cpp files. But you see, it does not work.
Should someone knows why and tell me how to use this in linux?

Thanks a lot!

I think, that you should add the paths to alglib's src in settings of compiler. In qt (but Windows) I'm add folder with source to project, and this error disappear

Hello!

You should compile .cpp files instead of including them. Compile .cpp as a separate object file, include .h - and it should work. Also, you should compile all cpp files - not just ones you need.
