# Tests for the special MAKE_PRINT_VAR_ON_ERROR variable, which prints the
|
|
# values of selected variables on error.
|
|
|
|
# XXX: As of 2020-10-23, the .ERROR_CMD variable is pointless in compat mode
|
|
# since at the point where it is filled in PrintOnError, the first command in
|
|
# gn->commands has been set to NULL already. This leaves .ERROR_CMD an empty
|
|
# list.

# See also:

# compat-error.mk
|
|
|
|
# XXX: As of 2021-02-04, PrintOnError calls Var_Subst with SCOPE_GLOBAL, which
|
|
# does not expand the node-local variables like .TARGET. This results in the
|
|
# double '${.TARGET}' in the output.
