EEOPT is a way to specify configuration flags to the Erika build environment.
EEOPTs can be specified as strings in the OS section of the OIL file. Examples:
EE_OPT = "DEBUG"; EE_OPT = "USE_UART";
Please notice that spelling inside the OIL file includes an underscore:
The only supported format for EEOPTs is a single name, which should be a valid C identifier (i.e., only Latin letters, digits, and underscore are allowed; the first character cannot be a digit). And any other format is not supported, and even if it works now, it may break in the future.
The following list shows EEOPTs supported by all architectures (except when stated otherwise)
