(one of many, I'm sure) In a project that I am working on, there is a tool used to generate a few header files that are used when compiling parts of the entire project. This tool, itself, relies on some of the libraries built in the project. These libraries must exist before the tool can be created. I'm struggling with how to build the libraries and then the header generating tool, as part of the 'make depend' phase of the entire project. I'd like to be able to just do "make obj depend && make all" and end up with all the binaries, libraries, etc built and ready to be installed. "make obj && make all" works... I mean, from a certain point of view, I know that I ought to be able to hook into the beforedepend: target in an individual Makefile, but I don't see how I'm supposed to do that at the top level Makefile, which uses bsd.subdir.mk. The top level Makefile drives the compilation of the libraries, then the tools, then some more libraries that require the tools, and finally the binaries that make up the project (which require both the libraries and the tools). Thanks for any insight! -Kurt
