You need to be a bit careful, though, that any new files you create
(if you do any development work) are in the source tree, not a build tree!
+Remember, that the source files in the build tree are {\em symbolic
+links} to the files in the source tree. (The build tree soon
+accumulates lots of built files like @Foo.o@, as well.) You can {\em
+delete} a source file from the build tree without affecting the source
+tree (though it's an odd thing to do). On the other hand, if you {\em
+edit} a source file from the build tree, you'll edit the source-tree
+file directly. (You can set up Emacs so that if you edit a source
+file from the build tree, Emacs will silently create an edited copy of
+the source file in the build tree, leaving the source file unchanged;
+but the danger is that you think you've edited the source file whereas
+actually all you've done is edit the build-tree copy. More commonly
+you do want to edit the source file.)
+
Like the source tree, the top level of your build tree must (a linked copy of)
the root directory of the @fptools@ suite.
Inside Makefiles, the root of your build tree is called @$(FPTOOLS_TOP)@.
extra consistency-checking code gets included) or off. And so on.
All of this stuff is called the {\em configuration} of your build.
-You set the configuration using an exciting two-step process.
+You set the configuration using an exciting three-step process.
\begin{description}
-\item[Step 1: system configuration.] This is easy, provided you
-have the programs mentioned in Section~\ref{sect_std-utils}. Just
-@cd@ to @$(FPTOOLS)@ and say @gmake configure@. This
-command does three things:
-\begin{itemize}
-\item
-It runs a GNU program called @autoconf@, which
+\item[Step 1: get ready for configuration.]
+Change directory to @$(FPTOOLS)@ and issue the following two commands (with no arguments):
+\begin{enumerate}
+\item @autoconf@. This GNU program
converts @$(FPTOOLS)/configure.in@ to a shell script
called @$(FPTOOLS)/configure@.
-This step is completely platform-independent; it just means
+\item @autoheader@. This second GNU program converts
+@$(FPTOOLS)/configure.in@ to @$(FPTOOLS)/mk/config.h.in@.
+\end{enumerate}
+Both these steps are completely platform-independent; they just mean
that the human-written file (@configure.in@) can be short, although
-the resulting shell script, @configure@ is long.
+the resulting shell script, @configure@, and @mk/config.h.in@, are long.
-\item It runs a second GNU program called @autoheader@, which converts
-@$(FPTOOLS)/configure.in@ to @$(FPTOOLS)/mk/config.h.in@.
-Again, this step is platform-independent.
+In case you don't have @autoconf@ and @autoheader@ we distribute
+the results, @configure@, and @mk/config.h.in@, with the source distribution.
+They aren't kept in the repository, though.
-\item It then runs the newly-created @configure@ script. @configure@'s mission
+\item[Step 2: system configuration.]
+Runs the newly-created @configure@ script, thus:
+\begin{verbatim}
+ ./configure
+\end{verbatim}
+@configure@'s mission
is to scurry round your computer working out what architecture it has,
what operating system, whether it has the @vfork@ system call,
where @yacc@ is kept, whether @gcc@ is available, where various
The latter is @#include@d by various C programs, which
can thereby make use of configuration information.
\end{itemize}
-\end{itemize}
-\item[Step 2: build configuration.] Next, you say how this build
+\item[Step 3: build configuration.] Next, you say how this build
of @fptools@ is to differ from the standard defaults by creating a new
file @mk/build.mk@
{\em in the build tree}. This file is the one and only
For example, @config.mk.in@ contains the definition:
\begin{verbatim}
- SUBDIRS = glafp-utils literate ghc
+ ProjectsToBuild = glafp-utils literate ghc hslibs
\end{verbatim}
The accompanying comment explains that this is the list of enabled
projects; that is, if (after configuring) you type @gmake all@
in @FPTOOLS_TOP@ three specified projects will be made.
If you want to add @happy@, you can add this line to @build.mk@:
\begin{verbatim}
- SUBDIRS += happy
+ ProjectsToBuild += happy
\end{verbatim}
or, if you prefer,
\begin{verbatim}
- SUBDIRS = glafp-utils literate ghc happy
+ ProjectsToBuild = glafp-utils literate ghc hslibs happy
\end{verbatim}
(GNU @make@ allows existing definitions to have new text appended using
the ``@+=@'' operator, which is quite a convenient feature.)
\begin{verbatim}
cd /scratch/joe-bloggs/myfptools-sun4
\end{verbatim}
+\item Prepare for system configuration:
+\begin{verbatim}
+ autoconf
+ autoheader
+\end{verbatim}
+(You can skip this step if you are starting from a source distribution,
+and you already have @configure@ and @mk/config.h.in@.)
+
\item Do system configuration:
\begin{verbatim}
- gmake configure
+ ./configure
\end{verbatim}
+
\item Create the file @mk/build.mk@,
adding definitions for your desired configuration options.

+We deal with this situation, by allowing the programmer to destructively modify
+the data field of the @ForeignObj@ to hold a special value the finaliser recognises,
