error: no matching function for call to ‘qrk::MonitorDataHandler::fetch(size_t&)’

[laper]

Hi everyone, I just have learned the C, but I have to use the http://svn.sourceforge.jp/svnroot/qrobosdk in linux, however it's wrote in c++. I try to do it well, but there are still some problems I can't fix. I go to trunk folder, and make, here is the error log http://pastebin.kde.org/paqeguuwi.
Thanks in advance.
