by real compiler classes. Also has some utility methods used by
several compiler classes.
The basic idea behind a compiler abstraction class is that each
instance can be used for all the compile/link steps in building a
single project. Thus, attributes common to all of those compile and
link steps -- include directories, macros to define, libraries to link
against, etc. -- are attributes of the compiler instance. To allow for
variability in how individual files are treated, most of those
attributes may be varied on a per-compilation or per-link basis.

list of arguments. (Splitting the string is done similarly to how
Unix shells operate: words are delimited by spaces, but quotes and
backslashes can override this. See

'sources' must be a list of filenames, most likely C/C++
files, but in reality anything that can be handled by a
particular compiler and compiler class (eg. MSVCCompiler can
handle resource files in 'sources'). Return a list of object
filenames, one per source filename in 'sources'. Depending on
the implementation, not all source files will necessarily be
compiled, but all corresponding object filenames will be
returned.
If 'output_dir' is given, object files will be put under it, while
retaining their original path component. That is, "foo/bar.c"
normally compiles to "foo/bar.o" (for a Unix implementation); if
'output_dir' is "build", then it would compile to
"build/foo/bar.o".
'macros', if given, must be a list of macro definitions. A macro
definition is either a (name, value) 2-tuple or a (name,) 1-tuple.
The former defines a macro; if the value is None, the macro is
defined without an explicit value. The 1-tuple case undefines a
macro. Later definitions/redefinitions/ undefinitions take
precedence.
'include_dirs', if given, must be a list of strings, the
directories to add to the default include file search path for this
compilation only.
'debug' is a boolean; if true, the compiler will be instructed to
output debug symbols in (or alongside) the object file(s).
'extra_preargs' and 'extra_postargs' are implementation- dependent.
On platforms that have the notion of a command-line (e.g. Unix,
DOS/Windows), they are most likely lists of strings: extra
command-line arguments to prepand/append to the compiler command
line. On other platforms, consult the implementation class
documentation. In any event, they are intended as an escape hatch
for those occasions when the abstract compiler framework doesn't
cut the mustard.
'depends', if given, is a list of filenames that all targets
depend on. If a source file is older than any file in
depends, then the source file will be recompiled. This
supports dependency tracking, but only at a coarse
granularity.
Raises CompileError on failure.

supplied to 'add_library()' and/or 'set_libraries()', and the
libraries supplied as 'libraries' (if any).
'output_libname' should be a library name, not a filename; the
filename will be inferred from the library name. 'output_dir' is
the directory where the library file will be put.
'debug' is a boolean; if true, debugging information will be
included in the library (note that on most platforms, it is the
compile step where this matters: the 'debug' flag is included here
just for consistency).

The "bunch of stuff" consists of the list of object files supplied
as 'objects'. 'output_filename' should be a filename. If
'output_dir' is supplied, 'output_filename' is relative to it
(i.e. 'output_filename' can provide directory components if
needed).
'libraries' is a list of libraries to link against. These are
library names, not filenames, since they're translated into
filenames in a platform-specific way (eg. "foo" becomes "libfoo.a"
on Unix and "foo.lib" on DOS/Windows). However, they can include a
directory component, which means the linker will look in that
specific directory rather than searching all the normal locations.
'library_dirs', if supplied, should be a list of directories to
search for libraries that were specified as bare library names
(ie. no directory component). These are on top of the system
default and those supplied to 'add_library_dir()' and/or
'set_library_dirs()'. 'runtime_library_dirs' is a list of
directories that will be embedded into the shared library and used
to search for other shared libraries that *it* depends on at
run-time. (This may only be relevant on Unix.)
'export_symbols' is a list of symbols that the shared library will
export. (This appears to be relevant only on Windows.)
'debug' is as for 'compile()' and 'create_static_lib()', with the
slight distinction that it actually matters on most platforms (as
opposed to 'create_static_lib()', which includes a 'debug' flag
mostly for form's sake).
'extra_preargs' and 'extra_postargs' are as for 'compile()' (except
of course that they supply command-line arguments for the
particular linker being used).
'target_lang' is the target language for which the given objects

platform/compiler combination. 'plat' defaults to 'os.name'
(eg. 'posix', 'nt'), and 'compiler' defaults to the default compiler
for that platform. Currently only 'posix' and 'nt' are supported, and
the default compilers are "traditional Unix interface" (UnixCCompiler
class) and Visual C++ (MSVCCompiler class). Note that it's perfectly
possible to ask for a Unix compiler object under Windows, and a
Microsoft compiler object under Unix -- if you supply a value for
'compiler', 'plat' is ignored.

u Generate C pre-processor options (-D, -U, -I) as used by at least
two types of compilers: the typical Unix compiler and Visual C++.
'macros' is the usual thing, a list of 1- or 2-tuples, where (name,)
means undefine (-U) macro 'name', and (name,value) means define (-D)
macro 'name' to 'value'. 'include_dirs' is just a list of directory
names to be added to the header file search path (-I). Returns a list
of command-line options suitable for either Unix compilers or Visual
C++.
