我想用opencv和pygame构建一个应用程序。这两个库已经安装了macports。我也在macports python中安装了py2app。 我运行一个简单的py2app脚本py2app error for opencv/macports app。如何使用headerpad_max_install_names标志编译opencv？
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，出现以下错误：“ValueError异常：新的Mach-O头太大搬迁”
是否有可能使一个应用程序捆绑与opencv和macports？
感谢您的帮助
更新：
这里是ronaldoussoren的答案伍兹霍尔海洋研究所是py2app developper：
Shared libraries on OSX contain an absolute path to their location, and likewise all used libraries are also mentioned using an absolute path. Py2app uses macholib to rewrite those mentions to relative paths starting with '@executable_path'. For libraries that are located in /opt/local the new path requires more space than the old one, hence the error message. One way to ensure that there is enough space is the linker flag "headerpad_max_install_names". I don't know how to tell darwinports to add this flag when building opencv.
还请注意，我有一个类似的问题与pyinstaller。
我试图修改opencv Portfile没有任何改变。我真的不知道该添加此链接器标志的位置。
任何想法如何解决它？

您是试图为您的系统创建一个可再发行组件包还是一个启动器？在后一种情况下，您可以使用_-A_ py2app选项来别名库，例如'python setup.py py2app -A' – anddam
