[Scons-users] SCon example for common build scenario

[William Blevins]

Ronex,

All these questions are easily answered by the documentation.

1. A. Use variant directory for multiple builds in a single source tree:
http://www.scons.org/doc/production/HTML/scons-user.html#chap-variants
1. B. For multiple builds in different trees you could just add a build
argument and flip compiler flags as you see fit:
http://www.scons.org/doc/production/HTML/scons-user.html#sect-command-line-options
2. This is the whole point of SCons:
http://www.scons.org/doc/production/HTML/scons-user.html#chap-depends
3. See 2.
4. With Execute on the binary:
http://www.scons.org/doc/production/HTML/scons-user.html#idm23282464 and
AlwaysBuild:
http://www.scons.org/doc/production/HTML/scons-user.html#idm340808 and
knowing your targets.
5. Hierarchical builds if desired or if its simple just use the SConstruct:
http://www.scons.org/doc/production/HTML/scons-user.html#chap-hierarchical
6. See 1.

V/R,
William
