Re: [Zope-dev] compiling Zope 2.4.1 on Mac OS 10.1
Sadly, I do have reasons forcing me to stay with Zope 2.3.2. I had no problems with Zope 2.3.2 or Python 2.0 and OS X 10.0.4... all I need to continue to work is to get Python 2.0 running on 10.1 :-(.

if you have no compelling reason for running Zope 2.3.2 and Python 2.0 i highly suggest moving up to a combination of Python 2.1 (which is much more OSX-friendly) and Zope 2.4.1. jens On Sunday, October 7, 2001, at 09:04 , Itai Tavor wrote: > Has anyone managed to do this procedure with Python 2.0?

Re: [Zope-dev] compiling Zope 2.4.1 on Mac OS 10.1
well, the actual extension does not matter. you could as well specify something like "--with-suffix=.mary_had_a_little_lamb" if you wanted... for a more technological explanation, when the compile is done the executable is copied into the root of the python source tree. by default the name of the executable is "python". this would not be a problem if it was not for the case insensitivity of the HFS file system used by most OS X users. there is a folder named "Python" in the root of the tree as well. trying to copy "python" into the root will fail because it collides with "Python". the "--with-suffix" will produce a binary with that suffix and that will avoid this collision. jens On Wednesday, October 3, 2001, at 11:03 , Leonardo Rochael Almeida wrote: > > > Mitchell L Model wrote: > >> [...] With the updates for OS 10.1 in Python 2.2a4, all I had to do to >> make both Python and Zope was: >> cd Python2.2a4 >> configure --with-suffix=.exe >> make >> sudo make install >> cd Zope >> python wo_pcgi.py > > > I don't know if it's just me, but this "--with-suffix=.exe", on an Mac OS > (the OS where you weren't suppose to need extensions) is extremely > disturbing. :-) > > Cheers, Leo > > PS: and I'm not a Mac user, just a Linux user who would like more > metadata in his operating system.

Re: [Zope-dev] compiling Zope 2.4.1 on Mac OS 10.1
False alarm for Python2.2a4. It does work It seems I was either hallucinating or had screwed something up. After discussions with Guido, after which I understood a lot better what was supposed to be happening and why, I started over, and this time it worked. With the updates for OS 10.1 in Python 2.2a4, all I had to do to make both Python and Zope was: cd Python2.2a4 configure --with-suffix=.exe make sudo make install cd Zope python wo_pcgi.py That's all. Just that one configure flag, and no global variables set. Very, very nice. What a delight to have a just released MacOS treated with respect by multi-platform software! By the way, Guido said that the Makefile.pre.in mechanism installed in python2.2/lib/config is for a deprecated third-party build mechanism, replaced by distutils. He suggests that Zope should maybeswitch to distutils. -- --- Mitchell ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Thanks!! Great information. Having said that, and having spent a couple of hours experimenting, let me try to clarify things a bit: 1. Python 2.2a4 defaults to --with-dylib, so you don't need that when making Python 2.2a4 as you did for 2.1. 2. Likewise, you don't need to set OPT the way the 2.1 README says for Mac OS 10. 3. Similarly, the Python2.2a4 configure.in knows to add -flat_namespace to Makefile.pre and therefore Makefile. 4. Both 2.1 and 2.2a4 correctly specify -undefined suppress. So, whereas I did need to fix the Python 2.1 Makefile to build it, I didn't need to fix the Python 2.2a4 Makefile to build it. (I guess I didn't try building Python 2.1 yesterday, or I would have realized the problem wasn't in Zope, but in Python, as you discovered.) From my experience this evening, I'm surprised that fixing the Python Makefile would allow you to compile Zope. It turns out that the zope configuration process uses the Makefile.pre.in installed in (typically) /usr/local/lib/python2.{1,2}/config. It also turns out that although Python 2.2a4 correctly adds -flat_namespace to Makefile.pre and Makefile, it doesn't add it to Makefile.pre.in! So for both 2.1 and 2.2 I had to add: LDSHARED= $(CC) $(LDFLAGS) -flat_namespace -undefined suppress to Makefile.pre.in, either in the Python src directory before doing 'make install' or in the /usr/local/lib/python2.{1,2}/config after doing the install.

I dont know) whereas most Unixes load each shared library with its own namespace [which is a bit of a technical abstraction and hand waving]. It sure looks to me like Apple is trying to fix the namespace collision problems with dyld, with that -twolevel_namespace (which sounds like a funky namespace munger). My best guess at noodling the error message is that it means "your library must use the symbol 'undefined error'" when the loader goes to load a name from the library and it is not present. It may be that there is something like a interrogation call to the library -- "do you have member X?" -- rather than what I'm used to, which is the loader looking in the library's table of contents. I suspect, but dont know, that it has to do with how Objective C methods get bound dynamically. Thats not a very helpful response, but until I go to an Apple store to get OS 10.1, I can't see it in action or read the docs. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
