The header files should be used from the uninstalled locations in the source tree instead of the installed locations. The use of the RPC headers needs to depend on the generated header files in an "obj" directory that is also not installed. The problem here is defining global rules causing the creation of missing files (ie: .h targets as opposed to sources). I think there is a need for an incremental build. For instance, I want to rebuild and install the world from sources on a read-only/remote/CDROM volume, but I don't have enough space for a full obj tree. These are competing goals, but it doesn't mean that compromise isn't possible. Specifically, the build environment needs to be seperated from the target environment, and thee needs to be at least two target environments (1 == kernel, 2 == ...). I would be happy to be able to delete one .obj file and have only the necessary things rebuilt (lib if it's used in a library, everything that uses the lib if it's static, etc., etc.). > [Stands up on soap box to begin preaching...
