You're /etc/profile or some other file should contain lines like this: export C_INCLUDE_PATH="/boot/develop/headers/be/bone/" export CPLUS_INCLUDE_PATH="/boot/develop/headers/be/bone/" if that is missing, or you'll have a ';' instead of a ':' as path separator (both variables can specify more than one path), it can't find the headers. HTH, Bye, Axel.
