Capturing the screen dump of CC

[Helen_14]

Hi, guys.

I want to capture the screen output of CC, warning and error messages, etc.. I tried both methods in your messages, i.e. sh > [file name] and script [file name]. But both capture only the commands, i.e. CC ..., but not its screen dump, i.e. warning and error messages. Actually, sh > and script behave similar to a simple redirection, >, in this case.

Any idea how to capture the warning and error messages of CC?

I'm running HP-UX 10.10 and 11.11, AIX, Solaris, etc..

cc -blah -blah > cc.output 2>&1

That's because the error messages are directed to stderr (file descriptor 2) rather than stdout (fdes 1). This is actually a standard unix convention and ALL error messages and warnings should go to stderr while normal messages should be directed to stdout.

Your solution is rather simple:
cc -o myfile myfile.c 2>myerrs
