3.3 Environment variables
SDCC recognizes the following environment variables:
- [SDCC_LEAVE_SIGNALS]SDCC
installs a signal handler to be able to delete
temporary files after an user break (C) or an exception.
If this environment variable is set, SDCC won't install the signal
handler in order to be able to debug SDCC.
- [TMP, TEMP, TMPDIR]Path, where
temporary files will be created. The order of the variables is the
search order. In a standard *nix environment these variables are
not set, and there's no need to set them. On Windows it's recommended
to set one of them.
- [SDCC_HOME]Path, see ''2.3 Install
and search paths''.
- [SDCC_INCLUDE]Path, see ''2.3 Install
and search paths''.
- [SDCC_LIB]Path, see ''2.3 Install and
search paths''.
There are some more environment variables recognized by SDCC, but
these are solely used for debugging purposes. They can change or disappear
very quickly, and will never be documented.
