Re: How to write/append the compiler output to a logfile

So you want to collect all C compilations output into a file which is the
input of a builder?
PRINT_CMD_LINE_FUNC is likely not the solution for that.

Changing CCCOM is o.k. It's not forbidden or advised against. It's normal
practice.

Also a command line with
"command source > output file"
Will overwrite the output file on each invocation. So you'd end up with
only the last one.

With this example:
'CCCOM': '$CC -o $TARGET[0] -c $CFLAGS $CCFLAGS $_CCCOMCOM $SOURCES' >
$TARGET[1]' but that's really changing CCCOM, so the (gcc) builder will not
be happy.

Would TARGET[1] be different for every target?

What is the post link/compile step. Is this run per compile and link? or is
this meant to run after all link and compiles are completed?
