[Scons-users] SCons popularity

Sat Jun 13 12:15:19 EDT 2015

Pawel,

I want to generalize Vasily's statement.  I already addressed this SCons
functionality misunderstanding in my earlier post, but I may have been too
sarcastic and no one read it or took it seriously.

You can pass any variable to the SCons environment with "scons
MYVAR=something" exactly the same way you can with Make:
http://www.scons.org/doc/HTML/scons-user/ch10s02.html

The Debian page explicitly tells Make users to support
http://www.gnu.org/prep/standards/standards.html#Command-Variables.  As
long as your SCons build also supports them, then I don't understand the
rub.  After all, Make doesn't have a default install target or a default
DESTDIR usage, so the real issue here may be that packagers using SCons
haven't made any effort to conform to GNU standards.  That's unfortunate in
its own right.

I agree with the others here that having a GNU-support wrapper for SCons
would be convenient, but isn't be hard to accomplish without a wrapper IHMO.

V/R,
William
