NAME
sp_makecheck - Read dependency files and check for missing dependencies
SYNOPSIS
sp_makecheck *.d
DESCRIPTION
A common technique with make is to use GCC to generate .d dependency files using the -MMD switch. This creates a files similar to foo.d:
foo.o foo.d: foo.cc foo.h
The problem is if a header file is removed, then make will complain that there is no rule to build foo.h. Adding a fake target is one way around this, but that requires additional .d's, and leaves old objects around.
sp_makecheck reads the specified dependency files, and checks for the existence of all dependencies in the file. If a file does not exist, it simply removes all of the targets.
