# $NetBSD: varname-make_print_var_on_error-jobs.mk,v 1.1 2020/10/23 06:18:23 rillig Exp $ # # 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. # As of 2020-10-23, .ERROR_CMD only works in parallel mode. .MAKEFLAGS: -j1 MAKE_PRINT_VAR_ON_ERROR= .ERROR_TARGET .ERROR_CMD all: @: command before @echo fail; false @: command after${:U, with variable expressions expanded} |
