NAME

mdep - generate the dependency list for C sources

SYNOPSIS

mdep [ -D symbol ] [ -I searchpath ] [ -r ] [ -x abc ]

sourcefiles

DESCRIPTION

The purpose of mdep is to generate the list of include file dependencies for some source file. The source files are expected to be C language source files, and may include either .c or .h files (or any other file, for that matter). The source files are examined for lines containing the `#include' statement (also `$include' for those of us who use UNIFY), and those file names are included in the list of dependencies. Additional features are provided by command line options: recursive expansion of include files (includes that include includes), suppression of expansion of specific include files, and Defining symbols so that the appropriate dependencies are generated.

Options

-D symbol: Define a symbol (as you would to the C preprocessor) to cause the recognition of the appropriate sections of code. Since mdep does not read #define statements in the source files, this is the only way of causing symbols to be defined. Conversely, symbols are #undef by default. Multiple occurrences of the -D option, with argument, may appear in the command line.
-I searchpath: Define a directory to be searched for include files, as is done for the C preprocessor. Multiple occurrences of the -I option, with argument, may appear in the command line.
-r: Perform recursive expansion of include files. Thus, if an include file includes other files, include those file names (and so on) in the dependency list. This option is moderated by the -x option.
-x filename: Exclude a file from recursive expansion. The filename associated with this option may omit the .h suffix, and mdep will append the suffix.

Arguments

sourcefile: One or more C source files to be processed. The files may actually be any ascii file.

EXAMPLES

The following example shows the command to process mdep.c and the output from the command:


% mdep -r mdep.c

mdep.o: \
        /usr/include/sys/types.h \
        /usr/include/sys/dir.h \
        /usr/include/stdio.h

To generate the dependency list for file `foo.c' that includes `foo.h' which includes some standard files:


% mdep -r -I/usr/local/include foo.c

foo.o: \
        ./foo.h \
        /usr/include/stdio.h
