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. -f
file- Write the include file dependencies to file, instead of the default .depend.
-p
- Cause
mkdep
to 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
