NAME
mkdep —
construct Makefile dependency
list
SYNOPSIS
mkdep |
[-ap] [-f
file] [flags]
file ... |
DESCRIPTION
mkdep takes a set of flags for the C compiler and a list
of C source files as arguments and constructs a set of include file
dependencies which are written into the file .depend,
for use by make(1). An example of its use in a Makefile might be:
CFLAGS= -O -I../include
SRCS= file1.c file2.c
depend:
mkdep ${CFLAGS} ${SRCS}
where the macro SRCS is the list of C source files and the macro CFLAGS is the list of flags for the C compiler.
The options are as follows:
-a- Append to the output file, so that multiple
mkdep's may be run from a single Makefile. -ffile- Write the include file dependencies to file, instead of the default .depend.
-p- Cause
mkdepto produce dependencies of the form:program: program.c
so that subsequent makes will produce program directly from its C module rather than using an intermediate .o module. This is useful for programs whose source is contained in a single module.
FILES
- .depend
- file containing list of dependencies
