我在python-for-android中修改了opencv配方,如下所示。

init .py

import os
import sh
from pythonforandroid.recipe import NDKRecipe
from pythonforandroid.toolchain import (
current_directory,
shprint,
)
from multiprocessing import cpu_count

class OpenCVRecipe(NDKRecipe):
version = '3.4.1'
url = 'https://github.com/Itseez/opencv/archive/{version}.zip'
#md5sum = '2ddfa98e867e6611254040df841186dc'
depends = ['numpy']
#patches = ['patches/p4a_build-2.4.10.1.patch']
generated_libraries = ['cv2.so']

def prebuild_arch(self, arch):
    self.apply_patches(arch)

def get_recipe_env(self, arch):
    env = super(OpenCVRecipe, self).get_recipe_env(arch)
    env['PYTHON_ROOT'] = self.ctx.get_python_install_dir()
    env['ANDROID_NDK'] = self.ctx.ndk_dir
    env['ANDROID_SDK'] = self.ctx.sdk_dir
    env['SITEPACKAGES_PATH'] = self.ctx.get_site_packages_dir()
    return env

def build_arch(self, arch):
    with current_directory(self.get_build_dir(arch.arch)):
        env = self.get_recipe_env(arch)
        cvsrc = self.get_build_dir(arch.arch)
        lib_dir = os.path.join(self.ctx.get_python_install_dir(), "lib")

        shprint(sh.cmake,
                '-DP4A=ON', '-DANDROID_ABI={}'.format(arch.arch),
                '-DCMAKE_TOOLCHAIN_FILE={}/platforms/android/android.toolchain.cmake'.format(cvsrc),
                '-DPYTHON_INCLUDE_PATH={}/include/python3.6'.format(env['PYTHON_ROOT']),
                '-DPYTHON_LIBRARY={}/lib/libpython3.6.so'.format(env['PYTHON_ROOT']),
                '-DPYTHON_NUMPY_INCLUDE_DIR={}/numpy/core/include'.format(env['SITEPACKAGES_PATH']),
                '-DANDROID_EXECUTABLE={}/tools/android'.format(env['ANDROID_SDK']),
                '-DBUILD_TESTS=OFF', '-DBUILD_PERF_TESTS=OFF',
                '-DBUILD_EXAMPLES=OFF', '-DBUILD_ANDROID_EXAMPLES=OFF',
                '-DPYTHON_PACKAGES_PATH={}'.format(env['SITEPACKAGES_PATH']),
                cvsrc,
                _env=env)
        shprint(sh.make, '-j', str(cpu_count()), 'opencv_python')
        shprint(sh.cmake, '-DCOMPONENT=python', '-P', './cmake_install.cmake')
        sh.cp('-a', sh.glob('./lib/{}/lib*.so'.format(arch.arch)), lib_dir)

recipe = OpenCVRecipe()

在python-for-android构建opencv时出现错误。

STDOUT:CMakeLists.txt:11(消息)处的CMake错误:

     

致命:不允许进行源内构建。

     

您应该为构建文件创建一个单独的目录。

     

-配置不完整,发生了错误!

如何解决?
