All source files in lib/hcrypto should be built the same way. Since this source directory is dependent on libroken then all source files must be built using the roken.h declarations and included headers. Also, there is no config.h in the local directory so angle brackets include of quotes should be used. Finally, because roken.h includes stdio.h, stdlib.h, stdarg.h, limits.h, strings.h, sys/types.h, etc., do not include them separately. Start all source files with #include <config.h> #include <roken.h> Change-Id: I09ab47f8a5472018efe6c8b59a0e51fde8f24724
