search CPP u-kernel, i knock in the good dors ?

Hi,
I search a CPP u-kernel, fiasco seems the best way but i see L4 not
writting in CPP... dude, and the first code i was read isn't commented
(kernel_console.cpp)

may be i thinks my first stuff is comment fiasco... about
kernel_console, why kconsole ? not native console writing ? may be i
try to write on...
i follow learn C++ programming by delanoy in french, may be take some
time but kconsole seems thinks me to kde console, may be i missing.

take care and best regard,
heitai.
