[vdr] compile error webvideo-0.0.3

Hi, I can't build the plugin.

menu.c: In member function ‘int cNavigationMenu::GoToURL(const char*, eLinkType, const char*)’: menu.c:497: warning: deprecated conversion from string constant to ‘char*’ In file included from download.c:18: /usr/include/libmms/mmsx.h:58: error: expected ‘,’ or ‘...’ before ‘this’ /usr/include/libmms/mmsx.h:60: error: expected ‘,’ or ‘...’ before ‘this’ /usr/include/libmms/mmsx.h:62: error: expected ‘,’ or ‘...’ before ‘this’ download.c: In static member function ‘static cMemoryBuffer* cCurlDownloader::DownloadToMemoryString(const char*)’: download.c:152: warning: deprecated conversion from string constant to ‘char*’ make: *** [download.o] Fehler 1

What can I do? Thanks Halim
