Re: First time scons user: Can't get a simple example working on windows machine

For the record (This was resolved on discord server)

On windows you'll need to run as
scons helloworld.exe

This is due to the actual target from

env.Program(target='helloworld', source=['helloworld.c']) # build targets

Being : helloworld.exe since on windows there's a Environment() variable
PROGRAMSUFFIX which is automatically appended to any target which doesn't
include it modifying the target file name.

If you wanted to always be able to have a command line argument
(target/alias) for scons regardless of the platform.
x=env.Program('helloworld','helloworld.c')
env.Alias("helloworld_app",x)

would work.
