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 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
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 gcc as the preprocessor and to ignore system headers, one would use
depend:
env MKDEP_CPP="gcc -E" MKDEP_CPP_OPTS=-MM mkdep \
${CFLAGS} ${SRCS}
The options are as follows:
