[SOLVED]Weird compile error QObject, QVector

[Alir3z4]

Hi
I have a weird compile error which is related to QVector :|
here's the error

if you want the whole source code, it's on the git repo
http://sourceforge.net/p/yodownet/git/..../tree/
or simply just clone it

git clone git://git.code.sf.net/p/yodownet/git yodownet-git

git clone git://git.code.sf.net/p/yodownet/git yodownet-git

To copy to clipboard, switch view to plain text mode 

i really get confused by this error and i tried alot of ways, but when i comment declaration/definition of this

QVector<UriStatus> uris() const;

QVector<UriStatus> uris() const;

To copy to clipboard, switch view to plain text mode 

then the project will compiled successfully

thanks
