CC
Specifies the C compiler to use. The specified compiler is expected to have options consistent with the GNU C compiler. The default is cc.
mkdep1
Construct makefile dependency list
Usage
mkdep [-ap]
[-f
file]
[flags]
file ...
Overview
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 cc as the preprocessor and to ignore 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 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.
