# Tests for the special MAKE_PRINT_VAR_ON_ERROR variable, which prints the
|
|
|
|
|
# values of selected variables on error.
|
|
|
|
|
#
|
|
|
|
|
# The variable .ERROR_CMD contains all commands of the target, with variable
|
|
|
|
|
# expressions expanded, just as they were printed to the shell command file.
|
|
|
|
|
#
|
|
|
|
|
# The commands in .ERROR_CMD are space-separated. Since each command usually
|
|
|
|
|
# contains spaces as well, this value is only intended as a first hint to what
|
|
|
|
|
# happened. For more details, use the debug options -de, -dj, -dl, -dn, -dx.
