I am having fun trying to compile the latest versions of 2ManDVD as per instructions but I get this error when I issue qmake 2ManDVD.pro :

interface.qrc: Warning: potential duplicate alias detected: 'execute.png'
interface.qrc: Warning: potential duplicate alias detected: 'son.png'
interface.qrc: Warning: potential duplicate alias detected: 'media3.png'
But more importantly this error when I run make afterwards :

g++ -c -pipe -O2 -pipe -Wformat -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fomit-frame-pointer -march=i586 -mtune=generic -fasynchronous-unwind-tables -O2 -pipe -Wformat -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fomit-frame-pointer -march=i586 -mtune=generic -fasynchronous-unwind-tables -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_WEBKIT_LIB -DQT_OPENGL_LIB -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/lib/qt4/mkspecs/linux-g++ -I. -I/usr/lib/qt4/include/QtCore -I/usr/lib/qt4/include/QtGui -I/usr/lib/qt4/include/QtOpenGL -I/usr/lib/qt4/include/QtWebKit -I/usr/lib/qt4/include -I/usr/lib -I/usr/include -I. -I. -o main.o main.cpp

cc1plus: error: unrecognized option `-Werror=format-security'
cc1plus: error: bad value (generic) for -mcpu= switch
make: *** [main.o] Error 1

I have run the above as the standard user and have tried as the superuser by running it after logging in via su .

I have looked on the authors (had to translate as it is in French ) website and used google with no luck. Any ideas?
