Use of the rtl-sdr library

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, ____________________________________________________________________ Justin Guérinot Intern | Capgemini Digital Engineering & Manufacturing Services Capgemini France | Toulouse Mob.: + 33 6 33 77 14 32 www.capgemini.com<http://www.capgemini.com/> [https://visualidentity.capgemini.com/capgemini.png] ____________________________________________________________________ Connect with Capgemini: [cid:image002.png@01D41855.E5D1B680]<https://www.capgemini.com/insights-and-resources/blogs>[cid:image003.png@01D41855.E5D1B680]<https://www.twitter.com/capgemini> [cid:image004.png@01D41855.E5D1B680] <https://www.facebook.com/capgemini> [cid:image005.png@01D41855.E5D1B680] <https://www.linkedin.com/company/capgemini> [cid:image006.png@01D41855.E5D1B680] <https://www.youtube.com/capgeminimedia> [cid:image007.png@01D41855.E5D1B680] <https://www.slideshare.net/capgemini> [cid:image009.png@01D41855.E5D1B680] <https://plus.google.com/+CapgeminiGlobal> Please consider the environment and do not print this email unless absolutely necessary.
