hi

my project not build complete, because i have:

<error>

</error>

in system installed

libcacard.x86_64 2:2.3.1-7.fc22                     
libcacard-devel.x86_64 2:2.3.1-7.fc22

in code i'm use only
#include <vreader.h>

from libcacard

part of code:

<code>

        VReader *_reader =
                static_cast<VReader*>(g_list_nth_data(_list, i));
         _readerList.append(_reader->name);

</code>

I accept any advice.
