Hello, L4-hackers. i have a short question.

Is iostream and string functions present in L4Re. Since i cannot use it. I have already included the line below in my makefile :

REQUIRES_LIBS   += libc_be_file_stdin libstdc++ cxx_libc_io cxx_io

And also, how to make hello-cfg be able to accept keyboard input. I have already include libc_be_file_stdin and include line below in my hello.cfg but it still not working :

L4.default_loader:start({ caps = { log = L4.Env.log,},l4re_dbg = L4.Dbg.Warn,log = { "l4linux", "yellow" },}, "rom/hello");

​Thank you for the answers​
