opencv / macports应用程序的py2app错误 . 如何使用headerpad_max_install_names标志编译opencv？

我正在尝试使用opencv和pygame构建一个应用程序 . 这两个库已经安装了macports . 我还在macports python中安装了py2app . 我正在运行一个简单的py2app脚本

from setuptools import setup

setup(
    app = [
        '/full/path/to/my_script.py',
    ],
    options={
        "py2app":{
            'argv_emulation': True, 
        }
    },
    setup_requires=['py2app']
)

不幸的是，py2app失败并出现以下错误：“ValueError：新的Mach-O标头太大而无法重新定位”

是否可以使用opencv和macports制作应用程序包？

谢谢你的帮助

更新：

以下是ronaldoussoren whoi是py2app开发者的答案：

OSX上的共享库包含其位置的绝对路径，同样也使用绝对路径提及所有使用的库 . Py2app使用macholib将这些提及重写为以'@executable_path'开头的相对路径 . 对于位于/ opt / local中的库，新路径比旧路径需要更多空间，因此出现错误消息 . 确保有足够空间的一种方法是链接器标志“headerpad_max_install_names” . 我不知道如何告诉darwinports在构建opencv时添加这个标志 .

还请注意我与pyinstaller有类似的问题 .

我试图修改opencv Portfile而不做任何更改 . 我真的不知道在哪里添加这个链接器标志 .

知道怎么解决吗？
