# Usage: sfmakedepend [-s] [-e ext] [-f file] [-I incdir] [-d objdir] |

# This is a makedepend script for Fortran, including Fortran 90. |
| 8 |
# It searches for Fortran style includes, C preprocessor includes, |
| 9 |
# and module dependencies to the extent that I understand them. |
| 10 |
# |
| 11 |
# Your files must have an extension listed in the @suffixes list |
| 12 |
# below. You might also want to modify $compile_string if you use |
| 13 |
# the -c or -p option. I call the compiler $(CFT) for historical |
| 14 |
# reasons. |
| 15 |
# |
| 16 |
# The switch [-s] is for stupid Fortran compilers that don't know |
| 17 |
# how to automatically send things through the C preprocessor. |
| 18 |
# It is possible to force 'make' to invoke 'cpp' to create a .f |
| 19 |
# file from a .F file (which has cpp directives), but make won't |
| 20 |
# know that a .f file will depend on the files that the .F file |
| 21 |
# included. This option will provide those dependencies. |
| 22 |
# |
| 23 |
# The [-e ext] switch is used with the [-s] switch for compilers |
| 24 |
# which expect an extension other than .f on source files. For |
| 25 |
# instance, for the Connection Machine one would use "-e fcm". |
| 26 |
# |
| 27 |
# The [-f file] switch is used to change the name of the current |
| 28 |
# Makefile. |
| 29 |
# |
| 30 |
# The [-I incdir] option tells sfmakedepend to look in alternate |
| 31 |
# directories for the include files. There can be several "-I dir" |
| 32 |
# options used at once. The current directory is still searched |
| 33 |
# first. |
| 34 |
# |
| 35 |
# The [-d objdir] option tells sfmakedepend that the object and |
| 36 |
# module files will be built in a separate directory from the sources. |
| 37 |
# |
| 38 |
# The [-m mod_ext] option tells sfmakedepend what extension to |
| 39 |
# use for Fortran 90 module files. The default for "use My_Mod" |
| 40 |
# is to list the dependency as "my_mod.mod" since this is what |
| 41 |
# NAG f90 and IBM xlf both use. Let me know if other compilers |
| 42 |
# use a different filename for the module information. |
| 43 |
# |
| 44 |
# The [-c] option specifies that the Cray compiler is being used. |
| 45 |
# This compiler requires a "-p file.o" option for each object file |
| 46 |
# that contains a module used by your current source file. |
| 47 |
# |
| 48 |
# The [-p] option specifies that the Parasoft compiler is being used. |
| 49 |
# This compiler requires a "-module file.o" option for each object file |
| 50 |
# that contains a module used by your current source file. |
| 51 |
# |
| 52 |
# The [-g] option specifies that the SGI compiler is being used. |
| 53 |
# This compiler names the module file in uppercase with the extension |
| 54 |
# .kmo. |
| 55 |
# |
| 56 |
# The [-h] option specifies that the HP compiler is being used. |
| 57 |
# This compiler names the module file in uppercase with the extension |
| 58 |
# .mod (added by Patrick Jessee who also fixed an include bug). |
| 59 |
# |
| 60 |
# The [-o obj_ext] option tells sfmakedepend what extension to use for |
| 61 |
# object files. The default is "o", but "obj", for instance, is |
| 62 |
# appropriate on MS-DOG etc. This option was added by Dave Love. |
| 63 |
# |
| 64 |
# The [-a add_ext] option (also added by Dave Love) tells sfmakedepend |
| 65 |
# to add targets with extension add_ext to the rules for object files. |
| 66 |
# For instance, to operate with (f77) ftnchek .prj files, you could use |
| 67 |
# `-a prj' to get rules like: |
| 68 |
# foo.prj foo.o: ... |
| 69 |
# |
| 70 |
# The final arguments contain the list of source files to be |
| 71 |
# searched for dependencies. |
| 72 |
# |
| 73 |
# EXAMPLE |
| 74 |
# sfmakedepend -I /usr/local/include *.F |
| 75 |
# |
| 76 |
# NOTES |
| 77 |
# This makedepend script is my first attempt at using perl 5 |
| 78 |
# objects. Therefore, it may not be the best example of how |
| 79 |
# to do this. Also, it requires perl 5 and will die if you |
| 80 |
# to use it with an older perl. The latest version is |
| 81 |
# available from: |
| 82 |
# |
| 83 |
# http://marine.rutgers.edu/po/perl.html |
| 84 |
# ftp://ahab.rutgers.edu/pub/perl/sfmakedepend |
| 85 |
# |
| 86 |
# Fortran 90 introduces some interesting dependencies. Two |
| 87 |
# compilers I have access to (NAG f90 and IBM xlf) produce a |
| 88 |
# private "mod_name.mod" file if you define "module mod_name" |
| 89 |
# in your code. This file is used by the compiler when you |
| 90 |
# use the module as a consistency check (type-safe). On the |
| 91 |
# other hand, the Cray and Parasoft compilers store the module |
| 92 |
# information in the object file and then files which use the |
| 93 |
# modules need to be compiled with extra flags pointing to the |
| 94 |
# module object files. |
| 95 |
# |
| 96 |
# This script assumes that all the files using and defining |
| 97 |
# modules are in the same directory and are all in the list of |
| 98 |
# files to be searched. It seems that the industry has not |
| 99 |
# settled on a practical way to deal with a separate modules |
| 100 |
# directory, anyway. |
| 101 |
# |
| 102 |
# I sometimes include non-existent files as a compile time |
| 103 |
# consistency check: |
| 104 |
# |
| 105 |
# #ifndef PLOTS |
| 106 |
# #include "must_define_PLOTS" /* bogus include */ |
| 107 |
# #endif |
| 108 |
# |
| 109 |
# This program warns about include files it can't find, but |
| 110 |
# not if there is a "bogus" on the same line. |
| 111 |
# |
| 112 |
# * The f90 module dependencies can confuse some versions of |
| 113 |
# make, especially of the System V variety. We use gnu |
| 114 |
# make because it has no problems with these dependencies. |
| 115 |
# |
| 116 |
# BUGS |
| 117 |
# It can sometimes produce duplicate dependencies. |
| 118 |
# |
| 119 |
# It treats C preprocessor includes the same as Fortran |
| 120 |
# includes. This can add unnecessary dependencies if you |
| 121 |
# use the -s flag and both kinds of includes. |
| 122 |
# |
| 123 |
# Please let me know if you find any others. |
