- *** USAGE NOTES ***
-
- depend.exe will generate dependency lists for C/C++ source files that can be
- inserted directly into a makefile. This readme provides more information
- about the options.
-
- usage:
- depend [-options] files...
-
- Note: all options must be separated by a space from their following arguments.
-
- Options:
-
- -1 Output one dependency per line
-
- Most makefiles are simpler to interpret if there is only one dependency
- per line. This is exactly what this option does. Here are 2 runs of
- the same file with and without the -1 option. Use whichever format you
- perfer.
-
- C:\src\depend>depend string.cpp
- string.obj: string.cpp string.hpp forcelib.h
-
-
- C:\src\depend>depend -1 string.cpp
- string.obj: \
- string.cpp \
- string.hpp \
- forcelib.h

-
- -d Display dependency tree listing
-
- Since depend uses a recursive algorithm to depend in each dependant
- file, it is sometimes valuable for debugging purposes to see which
- level a file was included at. Each level in indented by a tab char and
- is written to stderr, so to capture it in a file you'll have to
- re-route the stderr to a file. I don't know how to capture the stderr
- in dos. In NT you can use
-
- depend (args) > outfile 2>&1
-
- to connect the stdout and stderr and throw the whole mess into outfile.
- Here is a sample run:
-
- C:\winproj\petools>depend -d date.cpp
- date.cpp
- petools.h
- peassert.h
- date.h
- date.cpp[4]
- date.obj: date.cpp petools.h peassert.h date.h
-
- This output says that date.cpp depends on (includes) petools.h and
- date.h. petools.h depends on (includes) peasert.h. Notice that
- petools.h and date.h are both indented at the same level. [4] means
- date.cpp is dependant on a total of 4 files.
-
- ///////////////////////////////////////////////////////////////////////////////
-
- -ex @file Specify files to ignore in file
-
- Use this option to name a file that contains include files to exclude
- from a dependency list. MSDev v2.* uses a file named sysincl.dat. The
- format of the exclude file is one file per line and the exclude file
- must be either in the current directory or be named with an absolute
- (full) path. For example:
-
- depend -ex @\msdev\bin\sysincl.dat date.cpp
-
- ///////////////////////////////////////////////////////////////////////////////
-
- -i path Add path to include search
-
- Use this option to add includes to the list of directories to search to
- find included files. This path can be relative or absolute. This is
- the same as the compiler option. The INCLUDE environment variable is
- checked after all of these included directories are checked and the file
- being sought is not found. For example:
-
- depend -i ..\include -i ..\packages date.cpp
-
- ///////////////////////////////////////////////////////////////////////////////
-
- -o file Write output to file
-
- Use the option to save the output into file. The same thing can be done
- with redirection.
-
- ///////////////////////////////////////////////////////////////////////////////
-
- -oe file Write output and errors to file
-
- Use the option to save the output and any errors into file. The same
- thing can be done with redirection as in the -d option description.
-
- ///////////////////////////////////////////////////////////////////////////////
-
- -s Scan system includes (files included with <...> form)
-
- Normally, you don't want to include files from the standard C/C++
- library in you dependency lists since you shouldn't be changing these
- very often! If for some reason you want to see how these files fit into
- the dependency scheme, you can search them by turning on this option.
-
- ///////////////////////////////////////////////////////////////////////////////
-
- -v Display extra dependency and search information (verbose)
-
- This option display where it is searching for a file when it finds an
- included file. This output is helpful when you have 2 files identically
- named and want to be sure one is being included and one is not. For
- example, here is a sample run:
-
- C:\winproj\pedb>depend -v -i ..\petools unititr.cpp
- Searching for 'unititr.cpp' in:
- Searching for 'peassert.h' in:
- peassert.h
- ..\petools\peassert.h
- Searching for 'ts3iox.h' in:
- ts3iox.h
- ..\petools\ts3iox.h
- c:\msdev\include\ts3iox.h
- c:\msdev\mfc\include\ts3iox.h
-
- ts3iox.h: file not found
- Searching for 'unitkey.h' in:
- unitkey.h
- Searching for 'key.h' in:
- key.h
- unititr.obj: unititr.cpp pedbstd.h ..\petools\peassert.h ts3iox.h unitkey.h
-
- The last file in the searching for ... output is the one that was
- found. Notice that in this example the file ts3iox.h was not found. (I
- intentionally did not add ..\include to the search path to show this
- eror). This gives you an idea of where the generator looked for the
- includes as it found them.
