MKDEP(1) General Commands Manual MKDEP(1) NAME mkdep -- construct Makefile dependency list SYNOPSIS mkdep [-ap] [-f file] [flags] file ... DESCRIPTION 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 depen- dencies 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 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 user has the ability to change the preprocessor and preprocessor options used. For instance, to use cc as the preprocessor and to ig- nore system headers, one would use depend: env MKDEP_CPP="cc -E" MKDEP_CPP_OPTS=-MM mkdep \ ${CFLAGS} ${SRCS} The options are as follows: -a Append to the output file, so that multiple mkdep's may be run from a single Makefile. -f Write the include file dependencies to file, instead of the de- fault ``.depend''. -p Cause mkdep to produce dependencies of the form: program: program.c so that subsequent makes will produce program directly from its C module rather than using an intermediate .o module. This is useful for programs whose source is contained in a single mod- ule. ENVIRONMENT CC Specifies the C compiler to use. The specified com- piler is expected to have options consistent with the GNU C compiler. The default is cc. MKDEP_CPP Specifies the preprocessor to use. The default is "${CC} -E". MKDEP_CPP_OPTS Specifies the non-CFLAGS options for the preprocessor. The default is "-M". FILES .depend File containing list of dependencies. SEE ALSO cc(1), cpp(1), make(1) HISTORY The mkdep command appeared in 4.3BSD-Tahoe. FreeBSD 14.3 October 23, 2015 MKDEP(1)
