Re: Setting environment variable for make dist

[Bas Vodde]

Hi Gavin,

Related to why the variable must be set, check this stack overflow article:
http://superuser.com/questions/61185/why-do-i-get-files-like-foo-in-my-tarball-on-os-x

The Mac filesystem created a hidden file that causes problems when packaging a 
release.

I guess, autotools should actually handle this by default, but currently it 
doesn’t yet.

Right now, I just run a check. You can see what I’ve done at:
https://github.com/cpputest/cpputest/blob/master/Makefile.am
(line 344)

This ensures I don’t forget to do it manually. I haven’t found a way to do it 
automatically yet ;(

Thanks,

Bas
