U �A�`) � @ s. d Z ddlZddlZG dd� d�Zdd� ZdS )zmdistutils.extension Provides the Extension class, used to describe C/C++ extension modules in setup scripts.� Nc @ s" e Zd ZdZddd�Zdd� ZdS )� Extensiona� Just a collection of attributes that describes an extension module and everything needed to build it (hopefully in a portable way, but there are hooks that let you be as unportable as you need). Instance attributes: name : string the full name of the extension, including any packages -- ie. *not* a filename or pathname, but Python dotted name sources : [string] list of source filenames, relative to the distribution root (where the setup script lives), in Unix form (slash-separated) for portability. Source files may be C, C++, SWIG (.i), platform-specific resource files, or whatever else is recognized by the "build_ext" command as source for a Python extension. include_dirs : [string] list of directories to search for C/C++ header files (in Unix form for portability) define_macros : [(name : string, value : string|None)] list of macros to define; each macro is defined using a 2-tuple, where 'value' is either the string to define it to or None to define it without a particular value (equivalent of "#define FOO" in source or -DFOO on Unix C compiler command line) undef_macros : [string] list of macros to undefine explicitly library_dirs : [string] list of directories to search for C/C++ libraries at link time libraries : [string] list of library names (not filenames or paths) to link against runtime_library_dirs : [string] list of directories to search for C/C++ libraries at run time (for shared extensions, this is when the extension is loaded) extra_objects : [string] list of extra files to link with (eg. object files not implied by 'sources', static library that must be explicitly specified, binary resource files, etc.) extra_compile_args : [string] any extra platform- and compiler-specific information to use when compiling the source files in 'sources'. For platforms and compilers where "command line" makes sense, this is typically a list of command-line arguments, but for other platforms it could be anything. extra_link_args : [string] any extra platform- and compiler-specific information to use when linking object files together to create the extension (or to create a new static Python interpreter). Similar interpretation as for 'extra_compile_args'. export_symbols : [string] list of symbols to be exported from a shared extension. Not used on all platforms, and not generally necessary for Python extensions, which typically export exactly one symbol: "init" + extension_name. swig_opts : [string] any extra options to pass to SWIG if a source file has the .i extension. depends : [string] list of files that the extension depends on language : string extension language (i.e. "c", "c++", "objc"). Will be detected from the source extensions if not provided. optional : boolean specifies that a build failure in the extension should not abort the build process, but simply not install the failing extension.
