Hi, I'm interested in developing a "framework" building feature for libtool. Linking the shared library for a framework is exactly the same as linking a typical shared library. It's already quite close. The differences are described below, but they are summed up as, I need to be able to create a shared library artifact that doesn't start with lib, and the shared library needs to be placed into a particular folder hierarchy, so those parameters would probably have to be passed to libtool as well (in particular $(FRAMEWORK_VERSION) can't be guessed, and probably the source of Info.plist would also need to be passed).
Futhermore, I really don't understand all the use cases of libtool, and how/where those use cases would have to be modified to understand frameworks. In particular, I don't understand quite the best place or way to go about creating a .la file for the framework (it might be best to put it in the Resources directory, since that is what that directory is for, but how to I fix libtool to look in the right place). What all does a la file need to specify? So, to be specific, I find ltmain.sh a bit intimidating, as I am not very good with sh, and I don't immediately see where I can insert the appropriate changes. Is there an overview of ltmain.sh somewhere? The differences between a normal shared library and a framework are listed below: The runtime path is $(FRAMEWORK_DIRECTORY)/$(FRAMEWORK_NAME).framework/Versions/$(FRAMEWORK_VERSION)/$(FRAMEWORK_NAME) $(FRAMEWORK_DIRECTORY) is typically /Library/Frameworks $(FRAMEWORK_VERSION) is arbitrary, but typically A, B, C, (apple's convention) etc. $(FRAMEWORK_NAME) is the framework name, and what is passed to gcc as -framework $(FRAMEWORK_NAME) to link against the framework. The final object needs to be put into a particular folder hierarchy before it can be linked to other libraries. A framework is a file hierarchy that looks like this: $(FRAMEWORK_NAME).framework/ -->symbolic link $(FRAMEWORK_NAME) to Versions/Current/$(FRAMEWORK_NAME) -->symbolic link Resources/ to Versions/Current/Resources -->directory Versions/ -->symbolic link Current to latest installed version directory -->versioned library directories (arbitrary, but typically A, B, C, etc). Each directory contains the version of the linked shared object file called $(FRAMEWORK_NAME) and a "Resources" directory that contains a single xml file called Info.plist which contains the version number and vender, and any other files the library might need (like translations, etc). _______________________________________________ http://lists.gnu.org/mailman/listinfo/libtool
