  <para>

  &SCons; provides the ability to build a lot of different
  types of files right "out of the box."
  So far, we've been using &SCons;' ability to build
  programs, objects and libraries to
  illustrate much of the underlying functionality of &SCons;
  This section will describe all of the different
  types of files that you can build with &SCons;,
  and the built-in &Builder; objects used to build them.
  By default, all of the  &Builder; objects in this section
  can be built either with or without an explicit
  construction environment.

  </para>

  <section>
  <title>Programs:  the &Program; Builder</title>

    <para>

    As we've seen, the &b-link-Program; Builder
    is used to build an executable program.
    The &source; argument is one or more
    source-code files or object files,
    and the &target; argument is the
    name of the executable program name to be created.
    For example:

    </para>

    <programlisting>
      Program('prog', 'file1.o')
    </programlisting>

    <para>

    Will create the &prog;
    executable on a POSIX system,
    the &prog_exe; executable on a Windows system.

    </para>

    <para>

    The target file's prefix and suffix may be omitted,
    and the values from the
    &cv-link-PROGPREFIX;
    and
    &cv-link-PROGSUFFIX;
    construction variables
    will be appended appropriately.
    For example:

    </para>

    <programlisting>
      env = Environment(PROGPREFIX='my', PROGSUFFIX='.xxx')
      env.Program('prog', ['file1.o', 'file2.o'])
    </programlisting>

    <para>

    Will create a program named
    <filename>myprog.xxx</filename>
    regardless of the system on which it is run.

    </para>

    <para>

    If you omit the &target;,
    the base of the first input
    file name specified
    becomes the base of the target
    program created.
    For example:

    </para>

    <programlisting>
      Program(['hello.c', 'goodbye.c'])
    </programlisting>

    <para>

    Will create the &hello;
    executable on a POSIX system,
    the &hello_exe; executable on a Windows system.

    </para>

    <para>

    Two construction variables control what libraries
    will be linked with the resulting program.
    The &cv-link-LIBS; variable is a list of the names of
    libraries that will be linked into any programs,
    and the &cv-link-LIBPATH; variables is a list of
    directories that will be searched for
    the specified libraries.
    &SCons; will construct the right command-line
    options for the running system.
    For example:

    </para>

    <programlisting>
      env = Environment(LIBS = ['foo1', 'foo2'],
                        LIBPATH = ['/usr/dir1', 'dir2'])
      env.Program(['hello.c', 'goodbye.c'])
    </programlisting>

    <para>

    Will execute as follows on a POSIX system:

    </para>

    <screen>
      % <userinput>scons -Q</userinput>
      cc -o goodbye.o -c goodbye.c
      cc -o hello.o -c hello.c
      cc -o hello hello.o goodbye.o -L/usr/dir1 -Ldir2 -lfoo1 -lfoo2
    </screen>

    <para>

    And execute as follows on a Windows system:

    </para>

    <screen>
      C:\><userinput>scons -Q</userinput>
      cl /Fogoodbye.obj /c goodbye.c /nologo
      cl /Fohello.obj /c hello.c /nologo
      link /nologo /OUT:hello.exe /LIBPATH:\usr\dir1 /LIBPATH:dir2 foo1.lib foo2.lib hello.obj goodbye.obj
      embedManifestExeCheck(target, source, env)
    </screen>

    <para>

    The &cv-LIBS; construction variable
    is turned into command line options
    by appending the &cv-link-LIBLINKPREFIX; and &cv-link-LIBLINKSUFFIX;
    construction variables to the beginning and end,
    respectively, of each specified library.

    </para>

    <para>

    The &cv-LIBPATH; construction variable
    is turned into command line options
    by appending the &cv-link-LIBDIRPREFIX; and &cv-link-LIBDIRSUFFIX;
    construction variables to the beginning and end,
    respectively, of each specified library.

    </para>

    <para>

    Other relevant construction variables
    include those used by the &b-link-Object;
    builders to affect how the
    source files specified as input to the &t-Program;
    builders are turned into object files;
    see the next section.

    </para>

    <para>

    The command line used to control how a program is linked
    is specified by the &cv-link-LINKCOM; construction variable.
    By default, it uses the
    &cv-link-LINK; construction variable
    and the &cv-link-LINKFLAGS; construction variable.

    </para>

  <section>
  <title>Object-File Builders</title>

    <para>

    &SCons; provides separate Builder objects
    to create static and shared object files.
    The distinction becomes especially important when
    archiving object files into different types of libraries.

    </para>

    <section>
    <title>The &StaticObject; Builder</title>

      <para>

      The &b-link-StaticObject; Builder
      is used to build an object file
      suitable for static linking into a program,
      or for inclusion in a static library.
      The &source; argument is a single source-code file,
      and the &target; argument is the
      name of the static object file to be created.
      For example:

      </para>

      <programlisting>
        StaticObject('file', 'file.c')
      </programlisting>

      <para>

      Will create the &file_o;
      object file on a POSIX system,
      the &file_obj; executable on a Windows system.

      </para>

      <para>

      The target file's prefix and suffix may be omitted,
      and the values from the
      &cv-link-OBJPREFIX;
      and
      &cv-link-OBJSUFFIX;
      construction variables
      will be appended appropriately.
      For example:

      </para>

      <programlisting>
        env = Environment(OBJPREFIX='my', OBJSUFFIX='.xxx')
        env.StaticObject('file', 'file.c')
      </programlisting>

      <para>

      Will create an object file named
      <filename>myfile.xxx</filename>
      regardless of the system on which it is run.

      </para>

      <para>

      If you omit the &target;,
      the base of the first input
      file name specified
      beomces the base of the name
      of the static object file to be created.
      For example:

      </para>

      <programlisting>
        StaticObject('file.c')
      </programlisting>

      <para>

      Will create the &file_o;
      executable on a POSIX system,
      the &file_obj; executable on a Windows system.

      </para>

    </section>

    <section>
    <title>The &SharedObject; Builder</title>

      <para>

      The &b-link-SharedObject; Builder
      is used to build an object file
      suitable for shared linking into a program,
      or for inclusion in a shared library.
      The &source; argument is a single source-code file,
      and the &target; argument is the
      name of the shared object file to be created.
      For example:

      </para>

      <programlisting>
        SharedObject('file', 'file.c')
      </programlisting>

      <para>

      Will create the &file_o;
      object file on a POSIX system,
      the &file_obj; executable on a Windows system.

      </para>

      <para>

      The target file's prefix and suffix may be omitted,
      and the values from the
      &cv-link-SHOBJPREFIX;
      and
      &cv-link-SHOBJSUFFIX;
      construction variables
      will be appended appropriately.
      For example:

      </para>

      <programlisting>
        env = Environment(SHOBJPREFIX='my', SHOBJSUFFIX='.xxx')
        env.SharedObject('file', 'file.c')
      </programlisting>

      <para>

      Will create an object file named
      <filename>myfile.xxx</filename>
      regardless of the system on which it is run.

      </para>

      <para>

      If you omit the &target;,
      the base of the first input
      file name specified
      becomes the base of the name
      of the shared object file to be created.
      For example:

      </para>

      <programlisting>
        SharedObject('file.c')
      </programlisting>

      <para>

      Will create the &file_o;
      executable on a POSIX system,
      the &file_obj; executable on a Windows system.

      </para>

    </section>

    <section>
    <title>The &Object; Builder</title>

      <para>

      The &b-link-Object; Builder is a synonym for &b-link-StaticObject;

    <section>
    <title>The &StaticLibrary; Builder</title>

      <para>

      The &b-link-StaticLibrary; Builder
      is used to create a library
      suitable for static linking into a program.
      The &source; argument is one or more
      source-code files or object files,
      and the &target; argument is the
      name of the static library to be created.
      For example:

      </para>

      <programlisting>
        StaticLibrary('foo', ['file1.c', 'file2.c'])
      </programlisting>

      <para>

      The target file's prefix and suffix may be omitted,
      and the values from the
      &cv-link-LIBPREFIX;
      and
      &cv-link-LIBSUFFIX;
      construction variables
      will be appended appropriately.
      For example:

      </para>

      <programlisting>
        env = Environment(LIBPREFIX='my', LIBSUFFIX='.xxx')
        env.StaticLibrary('lib', ['file1.o', 'file2.o'])
      </programlisting>

      <para>

      Will create an object file named
      <filename>mylib.xxx</filename>
      regardless of the system on which it is run.

      </para>

      <programlisting>
        StaticLibrary('foo', ['file1.c', 'file2.c'])
      </programlisting>

      <para>

      If you omit the &target;,
      the base of the first input
      file name specified
      becomes the base of the name of the static object file to be created.
      For example:

      </para>

      <programlisting>
        StaticLibrary(['file.c', 'another.c'])
      </programlisting>

      <para>

      Will create the &libfile_a;
      library on a POSIX system,
      the &file_lib; library on a Windows system.

      </para>

    </section>

    <section>
    <title>The &SharedLibrary; Builder</title>

      <para>

      The &b-link-SharedLibrary; Builder
      is used to create a shared library
      suitable for linking with a program.
      The &source; argument is one or more
      source-code files or object files,
      and the &target; argument is the
      name of the shared library to be created.
      For example:

      </para>

      <programlisting>
        SharedLibrary('foo', ['file1.c', 'file2.c'])
      </programlisting>

      <para>

      The target file's prefix and suffix may be omitted,
      and the values from the
      &cv-link-SHLIBPREFIX;
      and
      &cv-link-SHLIBSUFFIX;
      construction variables
      will be appended appropriately.
      For example:

      </para>

      <programlisting>
        env = Environment(SHLIBPREFIX='my', SHLIBSUFFIX='.xxx')
        env.SharedLibrary('shared', ['file1.o', 'file2.o'])
      </programlisting>

      <para>

      Will create an object file named

  <title>Archives</title>

    <para>

    &SCons; provides Builder objects
    for creating two different types of archive files.

    </para>

    <section>
    <title>The &Tar; Builder</title>

      <para>

      The &b-link-Tar; Builder object uses the &tar;
      utility to create archives of files
      and/or directory trees:

      </para>

      <programlisting>
        env = Environment()
        env.Tar('out1.tar', ['file1', 'file2'])
        env.Tar('out2', 'directory')
      </programlisting>

      <screen>
        % <userinput>scons -Q .</userinput>
        tar -c -f out1.tar file1 file2
        tar -c -f out2.tar directory
      </screen>

      <para>

      One common requirement when creating a &tar; archive
      is to create a compressed archive using the
      <option>-z</option> option.
      This is easily handled by specifying
      the value of the &cv-link-TARFLAGS; variable
      when you create the construction environment.
      Note, however, that the <option>-c</option> used to
      to instruct &tar; to create the archive
      is part of the default value of &cv-TARFLAGS;,
      so you need to set it both options:

      </para>

      <programlisting>
        env = Environment(TARFLAGS = '-c -z')
        env.Tar('out.tar.gz', 'directory')
      </programlisting>

      <screen>
        % <userinput>scons -Q .</userinput>
        tar -c -z -f out.tar.gz directory
      </screen>

      <para>

      you may also wish to set the value of the
      &cv-link-TARSUFFIX; construction variable
      to your desired suffix for compress &tar; archives,
      so that &SCons; can append it to the target file name
      without your having to specify it explicitly:

      </para>

      <programlisting>
        env = Environment(TARFLAGS = '-c -z',
                          TARSUFFIX = '.tgz')
        env.Tar('out', 'directory')
      </programlisting>

      <screen>
        % <userinput>scons -Q .</userinput>
        tar -c -z -f out.tgz directory
      </screen>

    </section>

    <section>
    <title>The &Zip; Builder</title>

      <para>

      The &b-link-Zip; Builder object creates archives of files
      and/or directory trees in the ZIP file format.
      Python versions 1.6 or later
      contain an internal &zipfile; module
      that &SCons; will use.
      In this case, given the following
      &SConstruct; file:

      </para>

      <programlisting>
        env = Environment()
        env.Zip('out', ['file1', 'file2'])
      </programlisting>

      <para>

      Your output will reflect the fact
      that an internal Python function
      is being used to create the output ZIP archive:

      </para>

      <screen>
        % <userinput>scons -Q .</userinput>
        zip(["out.zip"], ["file1", "file2"])
