Bah, this didn't make it to the list due to the fact that I don't have pine set up to use my previous uni's e-mail.

Let's assume that I want to make a framework out of libfoo. I download, compile, and install it. Then I set up all of the required directory structure, copy the headers and rename libfoo.dylib to foo and put it in the correct place. Now all I need to do is use install_name_tool right? Okay, I need to change the install name from the following line to the next
/usr/local/lib/libfoo.dylib
@executable_path/../Frameworks/foo.framework/Versions/A/foo
assuming that I want package the framework with my app. Well, I'm out of luck since the second name is so much longer than the first. One way or another, I have to hack around this problem.
You are really making your own problem. Why on earth install the library in /usr/local if that is not the intended install path?

This was assuming that I wanted to package up a library that I also wanted to install.


Look at the way Apple do it with open source stuff. They use a 'dst' directory buried in /private/tmp or you home directory. that way the final install_name path will always be shorter. I have done this a lot and never had to lengthen a name.

You're right, that does sound like the way to go for that sort of thing. I'm not completely positive at this point, but I think my point was that the fact that one has to do this sort of thing at all is bad.
