###
### Makefile used to three-stage build a tree of source code.  Also used to
### compile other bundles, first with cc, then with gcc.
###

###
### USE OF THIS FILE REQUIRES GNU MAKE!!!
###

### The first versions of the file were written by Rich Pixley (rich@cygnus.com).
### Many subsequent additions (and current maintainance by) david d `zoo' zuhn,
### (zoo@cygnus.com).

### Every invocation of this Makefile needs to have a variable set (host), 
### which is the named used for ./configure, and also the prefix for the
### various files and directories used in a three stage.

ifndef host
error:
	@echo You must set the variable \"host\" to use this Makefile ; exit 1
else

### from here to very near the end of the file is the real guts of this 
### Makefile, and it is not seen if the variable 'host' is not set 

###
### START EDITTING HERE!!!
### These things will need to be set differently for each release.
###

### from which cvs tree are we working?
TREE := devo

### binaries should be installed into?
ROOTING := /usr/cygnus

### When working from a tagged set of source, this should be the tag.  If not,
### then set the macro to be empty.
CVS_TAG := 

### The name of the cvs module for this release.  The intersection of
### CVS_MODULE and CVS_TAG defines the source files in this release.

### Historically, this was identical to CVS_TAG.  This is changing.
RELEASE_TAG := latest-930319

### Historically, binaries were installed here.  This is changing.
release_root := $(ROOTING)/$(RELEASE_TAG)

### STOP EDITTING HERE!!!
### With luck, eventually, nothing else will need to be editted.
