[Scons-users] Compiling a program with scons

[Bill Deegan]

Owen,

You've not chosen the simplest project to start with.
Their build system uses autoconf logic which will determine information
about the current environment (compilers, libraries, system specific items)
and usually those generate a makefile and also some include files which set
preprocessor defines which are used in the source code.

You'll have to use Configure contexts in SCons to replicate this
functionality. It could get pretty involved.
See http://scons.org/doc/production/HTML/scons-user.html#chap-sconf for
more info about SCons' autoconf like capabilities.
