Single question FAQ

Attached are three files:


1.  automakefaq.def  is a list of questions and answers.  The list is
    one question long.  :-)  It points into the automake documentation.

2.  automakefaq.tpl  facilitates pointing into the documentation by
    adjusting symbolic names (e.g. "Program and Library Variables")
    into a spot on a page
    (e.g. "/manual/automake/html_node/automake_32.html#SEC32")

3.  automakeweb.tlib  a template library that might be useful for other
    generated web pages.

If the automake manual is rebuilt and the section numbering changes,
then you must do this:

  export AM_HTMLDOC_DIR=/path/to/manual/automake/html_node
  autogen automakefaq.def

Oh, I added a fourth file:  the generated html, too.


AutoGen Definitions automakefaq;

faq = {
  name = compiles;
  question = "Questions relating to compile options";
};

faq = {
  name = multi_cflags;
  question = "How can I set different compile flags for different compiles?";
  answer = <<-  END_OF_ANSWER
        It depends.  :-)  If all the compilation units for a particular executable
        take the same options, but the options for the different executables are
        different, then you may set a per-binary CFLAGS macro.  See <?
                doc-ref  sec-name = 'Program and Library Variables'
        ?>.

        <p>On the other hand, if the compilation units for the same executable
        must use different flags, or if the same source must be compiled with
        different flags, then you must write special rules.  See <?
                doc-ref  sec-name = 'Building etags and ctags'
        ?>.
        END_OF_ANSWER;
};

How can I set different compile flags for different compiles?

It depends. :-) If all the compilation units for a particular executable take the same options, but the options for the different executables are different, then you may set a per-binary CFLAGS macro. See Program and Library Variables.

On the other hand, if the compilation units for the same executable must use different flags, or if the same source must be compiled with different flags, then you must write special rules. See Building etags and ctags.
