MKDEP(1) FreeBSD General Commands Manual MKDEP(1)

construct Makefile dependency list

mkdep [
] [
-f file
] [
] file ...

The mkdep utility 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''. An example of its use in a Makefile might be:
CFLAGS= -O -I../include 
SRCS= file1.c file2.c 
	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 user has the ability to change the preprocessor and preprocessor options used. For instance, to use cc as the preprocessor and to ignore system headers, one would use
	env MKDEP_CPP="cc -E" MKDEP_CPP_OPTS=-MM mkdep \ 
The options are as follows:
Append to the output file, so that multiple mkdep's may be run from a single Makefile.
Write the include file dependencies to file, instead of the default ``.depend''.
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.

Specifies the C compiler to use. The specified compiler is expected to have options consistent with the GNU C compiler. The default is cc.
Specifies the preprocessor to use. The default is "${CC} -E".
Specifies the non-CFLAGS options for the preprocessor. The default is "-M".

File containing list of dependencies.

cc(1), cpp(1), make(1)

The mkdep command appeared in 4.3BSD-Tahoe.
