hi actually patch v1 used g++ and was compiling a "hello world" .cpp program but on of the comments was to change to gcc and c program. You can see a bit more about that here https://bugzilla.yoctoproject.org/show_bug.cgi?id=15712 What is your opinion ? Regarding the rest of the comments , I will try to change the code and submit v5 :) Thenx Christos
