fail, if a target was not generated

[Torsten Mohr]

Hi,

the commands in a certain rule to generate a target always give
a return code different to 0x00.

This is known and ok, the wanted output file is generated.

At the moment i have a rule like this:

$(OUTPUT) : $(INPUT)
        -command -o $@ -c $<


I'd like to have something like this:

$(OUTPUT) : $(INPUT)
        -command -o $@ -c $<
        fail_if_target_does_not_exist_or_is_older_than_input $@ $<


Is something like this possible?


Best regards,
Torsten.
