# 15.3. Telling SCons to Not Duplicate Source Files in the Variant Directory Tree

In most cases and with most tool sets, SCons can place its target files in a build subdirectory without duplicating the source files and everything will work just fine. You can disable the default SCons behavior by specifying `duplicate=0` when you call the `SConscript` function:

          SConscript('src/SConscript', variant_dir='build', duplicate=0)

When this flag is specified, SCons uses the variant directory like most people expect--that is, the output files are placed in the variant directory while the source files stay in the source directory:

          % ls src
          SConscript
          hello.c
          % scons -Q
          cc -c src/hello.c -o build/hello.o
          cc -o build/hello build/hello.o
          % ls build
          hello
          hello.o
