NAME

6       sp_makecheck - Read dependency files and check for missing dependencies
7

SYNOPSIS

9         sp_makecheck *.d
10

DESCRIPTION

12       A common technique with make is to use GCC to generate .d dependency
13       files using the -MMD switch.  This creates a files similar to foo.d:
14
15           foo.o foo.d: foo.cc foo.h
16
17       The problem is if a header file is removed, then make will complain
18       that there is no rule to build foo.h.  Adding a fake target is one way
19       around this, but that requires additional .d's, and leaves old objects
20       around.
21
22       sp_makecheck reads the specified dependency files, and checks for the
23       existence of all dependencies in the file.  If a file does not exist,
24       it simply removes all of the targets.
