43 Run PROGRAMS ARGS to compile a file, generating dependencies
46 Environment variables:
47 depmode Dependency tracking mode.
48 source Source file read by `PROGRAMS ARGS'.
49 object Object file output by `PROGRAMS ARGS'.
50 DEPDIR directory where to store dependencies.
51 depfile Dependency file to output.
52 tmpdepfile Temporary file to use when outputing dependencies.
53 libtool Whether libtool is used (yes/no).
55 Report bugs to <bug-automake@gnu.org>.

77 # Some modes work just like other modes, but use different flags. We
78 # parameterize here, but still list the modes in the big case below,

95 ## gcc 3 implements dependency tracking that does exactly what

97 ## it if -MD -MP comes after the -MF stuff. Hmm.
98 ## Unfortunately, FreeBSD c89 acceptance of flags depends upon
99 ## the command line argument order; so add the flags where they
100 ## appear in depend2.am. Note that the slowdown incurred here
101 ## affects only configure: in makefiles, %FASTDEP% shortcuts this.

122 ## There are various ways to get dependency output from gcc. Here's
123 ## why we pick this rather obscure method:
124 ## - Don't want to use -MD because we'd like the dependencies to end
125 ## up in a subdir. Having to rename by hand is ugly.
126 ## (We might end up doing this anyway to support other compilers.)
127 ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
128 ## -MM, not -M (despite what the docs say).
129 ## - Using -M directly means running the compiler twice (even worse

147 ## This next piece of magic avoids the `deleted header file' problem.
148 ## The problem is that when a header file which appears in a .P file
149 ## is deleted, the dependency causes make to die (because there is
150 ## typically no way to rebuild the header). We avoid this by adding
151 ## dummy dependencies for each header file. Too bad gcc doesn't do
152 ## this for us directly.
155 ## Some versions of gcc put a space before the `:'. On the theory
156 ## that the space means something, we add a space to the output as
158 ## Some versions of the HPUX 10.20 sed can't process this invocation
159 ## correctly. Breaking it into two sed invocations is a workaround.
