How to enable DVLOG?

[Kaiduan Xie]

Hi all,

I build chrome in debug mode, how to run chrome to be able to see the
DVLOG like below?

DVLOG(1) << "DisplayInfoFromSpec info=" << display_info.ToString()
<< ", spec=" << spec;

Thanks,

Hi,

please, see http://www.chromium.org/for-testers/enable-logging for details.

If I'm not mistaken, DVLOG(1) requires it to be a debug build and --v=2 (or greater value for v, per the instructions above v=1 turns on [D]VLOG(0))

Hope this helps,

Anton.

I find:

  --log --v=0 --vmodule=foo=1

more useful, since it disables all logging except the ones I'm interested in, producing less noisy output.  In this example, this enables output only from the file foo.cc.  You can use a comma-separate list too:

  --log --v=0 --vmodule=foo=1,bar=2

Thanks,
Roger
