stop build of kernel when there is a compilation error when using make -j
Hello, When I run "make" for a kernel tree, it stops immediately on the first compilation error. However, when I use "make -j 4" and there an error, it does not stop immediately because of the parallel build using several CPU cores Is there a way to cause "make -j 4" to stop on the first compilation error ? regards, Kevin

Control-C works pretty well. If you don't want to watch it scroll by waiting for an error, write an 'expect' script to do it for you.
Hi, What is "expect" script ? is it in bash? is there a good link for it ? rgs Kevin On Mon, Sep 9, 2013 at 4:15 AM, <Valdis.Kletnieks@vt.edu> wrote:

Expect is conceptually similar to awk, but awk scans files, expect runs processes interactively and parses the output. It has been part of unix (linux) for decades. It can be called from any shell.

Did you try "make -S" Regards, Binoy ________________________________________ From: kernelnewbies-bounces@kernelnewbies.org [kernelnewbies-bounces@kernelnewbies.org] on behalf of Greg Freemyer [greg.freemyer@gmail.com] Sent: Wednesday, September 11, 2013 5:02 PM To: Kevin Wilson; Valdis Kletnieks Cc: kernelnewbies@kernelnewbies.org Subject: Re: stop build of kernel when there is a compilation error when using make -j Kevin Wilson <wkevils@gmail.com> wrote:

Actually, that's the default, and -S only exists so you can cancel an inherited -k from above. The problem is that if 'make -j4' launches 4 sub-makes, the one that hits the error of course stops right away, but the other three will keep going until they come up for air, which can take some time....
