我想用opencv和pygame構建一個應用程序。這兩個庫已經安裝了macports。我也在macports python中安裝了py2app。 我運行一個簡單的py2app腳本py2app error for opencv/macports app。如何使用headerpad_max_install_names標誌編譯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失敗，出現以下錯誤：「ValueError異常：新的Mach-O頭太大搬遷」
是否有可能使一個應用程序捆綁與opencv和macports？
感謝您的幫助
更新：
這裏是ronaldoussoren的答案伍茲霍爾海洋研究所是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.
還請注意，我有一個類似的問題與pyinstaller。
我試圖修改opencv Portfile沒有任何改變。我真的不知道該添加此鏈接器標誌的位置。
任何想法如何解決它？
更新：這是我的Portfile

您是試圖爲您的系統創建一個可再發行組件包還是一個啓動器？在後一種情況下，您可以使用_-A_ py2app選項來別名庫，例如'python setup.py py2app -A' – anddam
