Re: improving lcov reports

[Iago Toral <itoral igalia com>]

Hi Stefan,

I've reviewing this and you're definitely right. Your workaround works
well for us too so I'll put this in b.g.o as soon as I can.

Btw, $(PWD) may have some problems, for example in my case the work dir
is symlinked (this is $PWD shows a path through symlinks) but the .info
files contains the real paths to files. As result, nothing gets
extracted from the info file when I use $PWD with the --extract option
unless I accessed the workdir through the real path to avoid symlinks.
To get rid of this I just used "pwd -P" instead:

lcov --extract ./coverage/$(PACKAGE)_tmp.info "`pwd -P`/*"
-o ./coverage/$(PACKAGE).info 

Thanks for your hint!
