I am trying to build an app using opencv and pygame. These two libs have been installed with macports. I also installed py2app in the macports python. I am running a simple py2app script
from setuptools import setup
setup(
app = [
'/full/path/to/my_script.py',
],
options={
"py2app":{
'argv_emulation': True,
}
},
setup_requires=['py2app']
)
Unfortunately, py2app fails with the following error :"ValueError: New Mach-O header is too large to relocate"
Is it possible to make an app bundle with opencv and macports?
Thanks for your help
Update:
Here is the answer of ronaldoussoren whoi is the 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.
Please also note that I've a similar issue with pyinstaller.
I've tried to modify the opencv Portfile without any changes. I don't really know where to add this linker flag.
Any idea how to fix it?
Update: Here is my Portfile

Update : The macport team worked on the problem but unfortunately their fix don't solve my problem. See http://trac.macports.org/ticket/36841
