It you want your build directory in another directory tree, try this:

import glob

env = Environment()

# variable to hold the build directory (relative)
mybuilddir = "../debug/myprogram"

# set up an alternate build directory
VariantDir("#" + mybuilddir, "#.", duplicate=0)

# target is myprogram.exe (win32) in the current directory
# lambda translates source file names relative to build directory
env.Program(
    "myprogram", source=map(lambda x: "#" + mybuilddir + "/" + x, glob.glob("*.cpp"))
)

this assumes that your dir tree looks like this

    ...\Debug
             \myprogram
             \hisprogram
             \herprogram
    ...\myprogram
    ...\hisprogram
    ...\herprogram

Note that you can use absolute path names for mybuilddir

errata: don't need Split() for source files


In the above situations, the target file 'myprogram.exe' is placed in the currect directory. If you want the target file to also be put into the build directory, try this:

import glob

env = Environment()

# variable to hold the build directory (relative)
mybuilddir = "../debug/myprogram"

# set up an alternate build directory
VariantDir("#" + mybuilddir, "#.", duplicate=0)

# target is myprogram.exe (win32) in the build directory
# lambda translates source file names relative to build directory
env.Program(
    mybuilddir + "/myprogram",
    source=map(lambda x: "#" + mybuilddir + "/" + x, glob.glob("*.cpp")),
)

Assuming that the project name is the same as the executable name is the same as the build directory name...

import glob

# project name is the root name for the executable and build directory
project = "myproject"

# buildroot is where all project build directories reside
buildroot = "../debug"

# -------
# From here on will be common to all projects

# holds the project build directory
builddir = buildroot + "/" + project
# holds the path to the target file in the project build directory
targetpath = builddir + "/" + project

env = Environment()

# define the build directory for scons
VariantDir("#" + builddir, "#.", duplicate=0)

env.Program(
    targetpath, source=map(lambda x: "#" + builddir + "/" + x, glob.glob("*.cpp"))
)
