Calculate the SDK root if it is specified. Note that, as of Xcode 7, Apple SDKs may contain textual stub libraries with .tbd extensions rather than the normal .dylib shared libraries installed in /. The Apple compiler tool chain handles this transparently but it can cause problems for programs that are being built with an SDK and searching for specific libraries. Callers of find_library_file need to keep in mind that the base filename of the returned SDK library file might have a different extension from that of the library file installed on the running system, for example: /Applications/Xcode.app/Contents/Developer/Platforms/ MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/ usr/lib/libedit.tbd vs /usr/lib/libedit.dylib �CFLAGSz-isysroot\s*(\S+)r( z/System/z/usr/z /usr/local/r N) r rY �re�searchrd re � startswithr r rL �group)rV �cflags�matchZ apply_rootr r r � _library_rootG s zUnixCCompiler._library_rootc sR � �fdd�d� � D �}t�j|�}dd� t�||�D �}ttjj|�}t |d�S )a/ Second-guess the linker with not much hard data to go on: GCC seems to prefer the shared library, so assume that *all* Unix C compilers do, ignoring even GCC's "-static" option. >>> compiler = UnixCCompiler() >>> compiler._library_root = lambda dir: dir >>> monkeypatch = getfixture('monkeypatch') >>> monkeypatch.setattr(os.path, 'exists', lambda d: 'existing' in d) >>> dirs = ('/foo/bar/missing', '/foo/bar/existing') >>> compiler.find_library_file(dirs, 'abc').replace('\\', '/') '/foo/bar/existing/libabc.dylib' >>> compiler.find_library_file(reversed(dirs), 'abc').replace('\\', '/') '/foo/bar/existing/libabc.dylib' >>> monkeypatch.setattr(os.path, 'exists', ... lambda d: 'existing' in d and '.a' in d) >>> compiler.find_library_file(dirs, 'abc').replace('\\', '/') '/foo/bar/existing/libabc.a' >>> compiler.find_library_file(reversed(dirs), 'abc').replace('\\', '/') '/foo/bar/existing/libabc.a' c 3 s | ]}�j � |d �V qdS ))Zlib_typeN)rA )�.0rJ )rh r0 r r � <genexpr>� s z2UnixCCompiler.find_library_file.<locals>.<genexpr>z dylib xcode_stub shared staticc s s | ]\}}t j�||�V qd S )N)r r rL )rr �rootZlib_namer r r rs � s N) r[ �maprq � itertools�product�filterr r �exists�next)r0 �dirsrh rD Z lib_names�rootsZsearched�foundr )rh r0 r �find_library_filej s z UnixCCompiler.find_library_file)NNNNN)Nr N) NNNNNr NNNN)r ) �__name__� __module__� __qualname__� compiler_typeZ executablesrd re Zsrc_extensionsZ obj_extensionZstatic_lib_extension�shared_lib_extensionZdylib_lib_extensionZxcode_stub_lib_extensionZstatic_lib_formatZshared_lib_formatZdylib_lib_formatZxcode_stub_lib_formatZ exe_extensionr9 r> rG rU rW r\ rg ri � staticmethodrq r~ r r r r r i sX 1( #r )�__doc__r rd rk rZ rv � r �dep_utilr Z ccompilerr r r �errorsr r r r �_logr Z _macos_compatr r r r r r r r r �<module> s
