hi
i've just found Eigen library1, and i'm exited to try matrix template type!
i've installed eigen libs in /usr/local/include/eigen3/
and added in config.make USER_CFLAGS = -I/usr/local/include/eigen3
BUT if i try to run the makefile there are a lot (i think in each declaration of eigen3) was not declared in this scope error.
this is my testApp.cpp:
#include "testApp.h"
#include <Eigen/Dense>
using namespace Eigen;
void testApp::setup(){
MatrixXd m(2,2);
m(0,0) = 3;
m(1,0) = 2.5;
m(0,1) = -1;
m(1,1) = m(1,0) + m(0,1);
cout << "Here is the matrix m:\n" << m << endl;
}
void testApp::update(){}
void testApp::draw(){}
some advice?
EDIT:
of course if i try to execute this code:
#include <iostream>
#include <Eigen/Dense>
using namespace Eigen;
int main()
{
MatrixXd m(2,2);
m(0,0) = 3;
m(1,0) = 2.5;
m(0,1) = -1;
m(1,1) = m(1,0) + m(0,1);
std::cout << m << std::endl;
}
and compile it as:
g++ -I/usr/local/include/eigen3/ e.cpp
everything is ok
