Makefile timestamp check to make file rebuild
 

Ive searched google for this answer as well as the gnu makefile
documentation page and I cant seem to find what Im looking for.

Im using gmake on solaris to build a project. I know that this would
work for a single file:

file.o: file.cpp
CC -c file.cpp -o file.o

But what I want to do is more general, since I have a list of OBJECTS
I want OBJECTS to somehow check all their associated .cpp files
and rebuild if one of them has been changed without having to
list each file seperately as above.

something like:

$(OBJECTS): ($SOURCES)
CC -c $*.cpp -o $@

How do I make this work?

The details of gmake are not relevant to the C language. Please
ask in a newsgroup that deals with your development environment.

Read the gmake documentation about "Inference rules".

This is off-topic in this group as it has nothing to do with C.

For help with gnu utils (such as make), ask in the following
newsgroup:

gnu.utils.help

Aha. I thought so.

One can always tell.

IOW, nobody here gives a **** about you or your problems.

You may find some or all of the following links helpful in understanding
why this is so:

Said in response to a message which, unlike yours, actually gave the
poster advice on where to find the answer.

It did? Show me where.

(Unless you've clipped something relevant, the above looks like "Not
here - try someplace else")

*You* clipped the following from Walter's reply to the OP:

Read the gmake documentation about "Inference rules".

So not only did Walter give a suggestion as to which group to post to,
he also gave a hint as to where to look in gmake's documentation.
