Provides the Extension class, used to describe C/C++ extension
|
modules in setup scripts.é Nc @ s" e Zd ZdZdddZdd ZdS )Ú Extensionaß 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.
