3 # Tests for the special MAKE_PRINT_VAR_ON_ERROR variable, which prints the
4 # values of selected variables on error.
6 # The variable .ERROR_CMD contains all commands of the target, with variable
7 # expressions expanded, just as they were printed to the shell command file.
9 # The commands in .ERROR_CMD are space-separated. Since each command usually
10 # contains spaces as well, this value is only intended as a first hint to what
11 # happened. For more details, use the debug options -de, -dj, -dl, -dn, -dx.
16 # XXX: As of 2021-02-04, PrintOnError calls Var_Subst with SCOPE_GLOBAL, which
17 # does not expand the node-local variables like .TARGET. This results in the
18 # double '${.TARGET}' in the output.
20 # As of 2020-10-23, .ERROR_CMD only works in parallel mode.
