Use of the rtl-sdr library

[GUERINOT, Justin]

Hello,

I am trying to develop a simple application using rtlsdr's library functions as simple as rtlsdr_get_device_count().
But, at the moment of compilation GCC is unable to find the reference to the function and exit the errors :
« Undefinded reference to the function rtlsdr_get_device_count() ; »
« ld returned 1 exit status »

My code is below :

#include <stdio.h>
#include <stdlib.h>
#include «/usr/include/rtl-sdr.h »

int main(int argc, char *argv[])
{
              int device_count ;
              device_count = rtlsdr_get_device_count() ;
              printf(« Device ID : %d », device_count) ;
              return 0 ;
}

That sounds normal because source code and headers files are dispatched in different files and not compiled.
A solution would be to copy each headers, each sources together and compile them. But it should take a lot of times...

It should exists another solution but I don't find it.

For example, in the acarsdec software, how the developer was able to compile his software ?

I hope I well explained my issue,

Thank you in advance for your help

Best regards,
