Re: Are there firls and kaiser filter methods for C++ OOT?

[Marcin Puchlik]

So while running: g++ -gnuradio-filter main.cpp   I get:

/bin/ld: /tmp/ccChkcfC.o: in function `main':
main.cpp:(.text+0x8d): undefined reference to `gr::filter::firdes::low_pass(double, double, double, double, gr::fft::window::win_type, double)'
collect2: error: ld returned 1 exit status

main.cpp is:

#include <iostream>
#include <gnuradio/math.h>
#include <gnuradio/filter/firdes.h>
#include <gnuradio/fft/window.h>

using namespace std;

int main() {
        cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
        std::vector<float> taps = gr::filter::firdes::low_pass(1, 1, 0.3, 0.1);
        return 0;
}

No idea. Give me the full output (the exact error).
