[Scons-users] Pass multiple build flags on the command line

[Andrew C. Morrow]

Hi Dirk -

Thanks for posting this, I had often wondered about this. I do have some
follow up questions:

- Is the same effect achievable somehow with Options, rather than
Variables? The project I work on currently uses Options for everything, and
I'm somewhat hesitant to introduce Variables too.

- What to do about paths with spaces? I worry about windows, sometimes.

- How should this work with things that are naturally lists? If I wanted to
pass in multiple CPPPATH and LIBPATH, for instance (assuming variables
approach):

scons CPPPATH="/opt/local/include;/usr/local/include"
LIBPATH="/opt/local/lib;/usr/local/lib"

This doesn't seem like it would do the right thing. Something else? Is
there another trick for handling these? Is it also applicable to Options?

Thanks,
Andrew
