"""setup for the dlib project Copyright (C) 2015 Ehsan Azar (dashesy@linux.com) License: Boost Software License See LICENSE.txt for the full license. This file basically just uses CMake to compile the dlib python bindings project located in the tools/python folder and then puts the outputs into standard python packages. To build the dlib: python setup.py build To build and install: python setup.py install To package the wheel (after pip installing twine and wheel): python setup.py bdist_wheel To upload the binary wheel to PyPi twine upload dist/*.whl To upload the source distribution to PyPi python setup.py sdist upload To repackage the previously built package as wheel (bypassing build): python setup.py bdist_wheel --repackage To install a develop version (egg with symbolic link): python setup.py develop To exclude/include certain options in the cmake config use --yes and --no: for example: --yes DLIB_NO_GUI_SUPPORT: will set -DDLIB_NO_GUI_SUPPORT=yes --no DLIB_NO_GUI_SUPPORT: will set -DDLIB_NO_GUI_SUPPORT=no Additional options: --compiler-flags: pass flags onto the compiler, e.g. --compiler-flag "-Os -Wall" passes -Os -Wall onto GCC. --debug: makes a debug build --cmake: path to specific cmake executable --G or -G: name of a build system generator (equivalent of passing -G "name" to cmake) """ from __future__ import print_function import shutil import stat import errno import subprocess from setuptools.command.bdist_egg import bdist_egg as _bdist_egg from setuptools.command.develop import develop as _develop from distutils.command.build_ext import build_ext as _build_ext from distutils.command.build import build as _build from distutils.errors import DistutilsSetupError from distutils.spawn import find_executable from distutils.sysconfig import get_python_inc, get_python_version, get_config_var from distutils.version import LooseVersion from distutils import log import os import sys from setuptools import Extension, setup import platform from subprocess import Popen, PIPE, STDOUT import signal from threading import Thread import time import re import pkg_resources import textwrap # change directory to this module path try: this_file = __file__ except NameError: this_file = sys.argv[0] this_file = os.path.abspath(this_file) if os.path.dirname(this_file): os.chdir(os.path.dirname(this_file)) script_dir = os.getcwd() def _get_options(): """read arguments and creates options """ _cmake_path = find_executable("cmake") _cmake_extra = [] _cmake_config = 'Release' _options = [] opt_key = None _generator_set = False # if a build generator is set argv = [arg for arg in sys.argv] # take a copy # parse commandline options and consume those we care about for opt_idx, arg in enumerate(argv): if opt_key == 'cmake': _cmake_path = arg elif opt_key == 'compiler-flags': _cmake_extra.append('-DCMAKE_CXX_FLAGS={arg}'.format(arg=arg.strip())) elif opt_key == 'yes': _cmake_extra.append('-D{arg}=yes'.format(arg=arg.strip())) elif opt_key == 'no': _cmake_extra.append('-D{arg}=no'.format(arg=arg.strip())) elif opt_key == 'G': _cmake_extra += ['-G', arg.strip()] _generator_set = True if opt_key: sys.argv.remove(arg) opt_key = None continue # Keep -G to resemble cmake's if arg == '-G' or arg.lower() == '--g': opt_key = 'G' sys.argv.remove(arg) continue if not arg.startswith('--'): continue opt = arg[2:].lower() if opt == 'cmake': _cmake_path = None opt_key = opt sys.argv.remove(arg) continue elif opt in ['yes', 'no', 'compiler-flags']: opt_key = opt sys.argv.remove(arg) continue custom_arg = True if opt == 'debug': _cmake_config = 'Debug' elif opt == 'release': _cmake_config = 'Release' elif opt in ['repackage']: _options.append(opt) else: custom_arg = False if custom_arg: sys.argv.remove(arg) return _options, _cmake_config, _cmake_path, _cmake_extra, _generator_set options, cmake_config, cmake_path, cmake_extra, generator_set = _get_options() def reg_value(rk, rname): """enumerate the subkeys in a registry key :param rk: root key in registry :param rname: name of the value we are interested in """ try: import _winreg as winreg except ImportError: # noinspection PyUnresolvedReferences import winreg count = 0 try: while True: name, value, _ = winreg.EnumValue(rk, count) if rname == name: return value count += 1 except OSError: pass return None def enum_reg_key(rk): """enumerate the subkeys in a registry key :param rk: root key in registry """ try: import _winreg as winreg except ImportError: # noinspection PyUnresolvedReferences import winreg sub_keys = [] count = 0 try: while True: name = winreg.EnumKey(rk, count) sub_keys.append(name) count += 1 except OSError: pass return sub_keys try: from Queue import Queue, Empty except ImportError: # noinspection PyUnresolvedReferences from queue import Queue, Empty # python 3.x _ON_POSIX = 'posix' in sys.builtin_module_names def enqueue_output(out, queue): for line in iter(out.readline, b''): queue.put(line) def _log_buf(buf): if not buf: return if sys.stdout.encoding: buf = buf.decode(sys.stdout.encoding) buf = buf.rstrip() lines = buf.splitlines() for line in lines: log.info(line) def get_cmake_version(cmake_path): p = re.compile("version ([0-9.]+)") cmake_output = subprocess.check_output(cmake_path + " --version").decode("utf-8");
