我正在尝试使用 opencv 和 pygame 构建一个应用程序。这两个库已与 macports 一起安装。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: New Mach-O header is too large to relocate”
是否可以使用 opencv 和 macports 制作应用程序包？
谢谢你的帮助
更新：
这是 ronaldoussoren whoi 是 py2app 开发者的答案：
OSX 上的共享库包含指向其位置的绝对路径，同样所有使用的库也使用绝对路径提及。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，因此会出现错误消息。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 时添加此标志。
另请注意，我对 pyinstaller 也有类似的问题。
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。
知道如何解决吗？
