title: How can i compile a project with libqrencode?
body: <p>I am trying to compile this <a href="https://github.com/fukuchi/libqrencode/issues/26" rel="nofollow">code</a> but it always gives me "Undefined reference to QRcode_encodeString and QRcode_free". I have done the ./configure, make and make install, no errors where shown. I have no idea what flags i need to use in other to compile it. I'm currently using slackware 3.10 i686. I'm only trying to compile with gcc -Wall main.c. I'm still trying to understand linux libraries and shared objects. Any clue to what might be the problem? My source code is in the same directory as the qrencode.h file. I tried #include  and "qrencode.h". </p>
