问题 I\'ve tried this and run in to problems a bunch of times in the past. Does anyone have a recipe for installing lxml on OS X without MacPorts or Fink that definitely works? Preferably with complete 1-2-3 steps for downloading and building each of the dependencies. 回答1: Thanks to @jessenoller on Twitter I have an answer that fits my needs - you can compile lxml with static dependencies, hence avoiding messing with the libxml2 that ships with OS X. Here's what worked for me: cd /tmp curl -O http

Multiple versions of Python on OS X Leopard

阅读更多关于 Multiple versions of Python on OS X Leopard

问题 I currently have multiple versions of Python installed on my Mac, the one that came with it, a version I downloaded recently from python.org, an older version used to run Zope locally and another version that Appengine is using. It\'s kind of a mess. Any recommendations of using one version of python to rule them all? How would I go about deleted older versions and linking all of my apps to a single install. Any Mac specific gotchas I should know about? Is this a dumb idea? 回答1: There's

How can we restore ppc/ppc64 as well as full 10.4/10.5 SDK support to Xcode 4?

Since Apple only ships SDK 10.6 with Xcode4, developing PPC applications with Xcode4 became impossible. While it is possible to develop applications with Xcode4 that can also run on 10.5 and maybe even on 10.4 systems (by selecting SDK 10.6, but deployment target 10.5 or 10.4), they will only run on Intel Macs because you need at least SDK 10.5 for building PPC applications. Further there are some rare cases, where you really need to build against an SDK prior to 10.6 for full platform support, e.g. if certain deprecated functionality has vanished completely from the 10.6 SDK, but you'll have

What is the “Illegal Instruction: 4” error and why does “-mmacosx-version-min=10.x” fix it?

问题 I get Illegal Instruction: 4 errors with binaries compiled with GCC 4.7.2 under Mac OS X 10.8.2 (\"Mountain Lion\"), when those binaries are run under Mac OS X 10.7.x (\"Lion\") and earlier versions. The binaries work properly under Mac OS X 10.8.x. I added -mmacosx-version-min=10.5 to my compile flags and this seems to help resolve the issue for 10.5.x, 10.6.x and 10.7.x clients, whatever that issue is. Which gets to my question(s): What is the Illegal Instruction: 4 error? Why does -mmacosx
