problem when compiling the demo of hydrax in debug mode

Hello
I dowload Hydrax V 0.5.1. I try to compile the demo with visual c++ 2008, In mode release its Ok, But in mode debug i have a problem :
"....line of commande options '/GL' et '/ZI' is non compatibles...."
(I compiled the Hydrax in the two mode without any problem)
Help please

go to the project properties and in C/C++ in General change Debug information format to something else
