I don't have the newest version of Lattice C, so things might have changed...

If you start LC1.TTP and LC2.TTP yourself (I mean: not using LC.TTP) you
can use redirection in the command string offered to these programs (they
handle redirection themselves); e.g.

    LC1.TTP >error1.out lc1_options myfile
    LC2.TTP >error2.out lc2_options myfile

Note that the redirection must be the first argument, or it will be
misinterpreted. Also note that you have to quote the '>' if you're
running from a shell that handles redirection (<,>,<<,>>), or else the
shell will try to do the redirection (which might fail).

There's another annoying fact about Lattice discriminating between console
and file output (again, maybe it has changed):

If you use LC.TTP to compile, you will notice it will wait for a keypress
before finishing. This is quite annoying if you run from a make program, or
use batch processing. I can understand why it has been done: to be able
to see the compiler output before returning to the Desktop.
If you use LC1.TTP and LC2.TTP to compile, you will see they also wait
for a keypress before finishing. The odd thing is, they don't wait when
started from LC.TTP (this one starts them each in turn). The reason is
that LC.TTP starts them each with a first argument of '>CON:'; this
value is treated as a special one by both LC1.TTP and LC2.TTP.

When I found out about all that, I decided to write my own cc program
that starts the LC1.TTP and LC2.TTP with a first argument of '>CON:',
also starts the linker LINK.TTP with a suitable link description file,
handles its parameters more 'a la Unix' and DOES NOT WAIT FOR A KEYPRESS.
(If someone's interested, mail me).
The output is still directed to the console, but that's no problem:
if fastdump.prg is installed (can even start it at that moment) an
Alt-Help will do a fast ascii screen dump to my printer, which is even
nicer than having error messages in a file (unless you have something
like the Unix utility error that can merge an error file into your
source file).

Hope this helps you out -
