Source-only distributions are either bugfix releases or snapshots of
current state of development. The release has undergone some testing.
-
-GHC~2.08 is a source-only release, and it can be compiled up using
-either GHC~2.02 (or subsequent bugfix releases) or the Good Old
-Compiler, GHC~0.29. Compiling with 0.29 is recommended if you're
-a performance junkie, as 0.29 (still) generates zippier code, but
-GHC~2.08 is catching up.

Suppose that you untar a binary-distribution bundle, thus:
\begin{verbatim}
% cd /your/scratch/space
- % gunzip < ghc-2.08-sun-sparc-solaris2.tar.gz | tar xvf -
+ % gunzip < ghc-x.xx-sun-sparc-solaris2.tar.gz | tar xvf -
\end{verbatim}
Then you should find a single directory, @fptools@, with the following
structure:
directly by the user. These are the files that must end up in your path.
\item[@lib/<platform>@] contains platform-specific support files for the installation.
Typically there is a subdirectory for each @fptools@ project, whose name is
-the name of the project with its version number.
-For example, for GHC 2.08 there would be a sub-directory @ghc-2.08/@.

+number of GHC in the bundle.
These sub-directories have the following general structure:

% cd /your/scratch/space
- % gunzip < ghc-2.08-sun-sparc-solaris2.tar.gz | tar xvf -
- % gunzip < happy-1.09-sun-sparc-sunos4.tar.gz | tar xvf -

+ % gunzip < happy-x.xx-sun-sparc-sunos4.tar.gz | tar xvf -

When you do multiple unpacks like this, the top level @Makefile@, @README@,
and @INSTALL@ get overwritten each time. That's fine -- they should be the same.

-will also make a link (in the binary installation directory) from
-@ghc@ to @ghc-2.08@. If you install multiple versions of GHC then the
-last one ``wins'', and ``@ghc@'' will invoke the last one installed.

just the @happy/@ directory.
\subsection{Build trees}
All of this stuff is called the {\em configuration} of your build.
You set the configuration using an exciting three-step process.
\begin{description}
-\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 @$(FPTOOLS)/configure@.
-\item @autoheader@. This second GNU program converts
-@$(FPTOOLS)/configure.in@ to @$(FPTOOLS)/mk/config.h.in@.
-\end{enumerate}
+\item[Step 1: get ready for configuration.] Change directory to
+@$(FPTOOLS)@ and issue the command @autoconf@ (with no
+arguments). This GNU program converts @$(FPTOOLS)/configure.in@ to a
+shell script called @$(FPTOOLS)/configure@.
+
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@, and @mk/config.h.in@, are long.
+the resulting shell script, @configure@, and @mk/config.h.in@, are
+long.
-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.
+In case you don't have @autoconf@ we distribute the results,
+@configure@, and @mk/config.h.in@, with the source distribution. They
+aren't kept in the repository, though.
\item[Step 2: system configuration.]
Runs the newly-created @configure@ script, thus:
The latter is @#include@d by various C programs, which
can thereby make use of configuration information.
\end{itemize}
-
+@configure@ caches the results of its run in @config.cache@.
+Quite often you don't want that; you're running @configure@ a second time
+because something has changed. In that case, simply delete @config.cache@.
\item[Step 3: build configuration.] Next, you say how this build
of @fptools@ is to differ from the standard defaults by creating a new
You do not {\em have} to have a @mk/build.mk@ file at all; if you don't,
you'll get all the default settings from @mk/config.mk.in@.
+You can also use @build.mk@ to override anything that @configure@ got
+wrong. One place where this happens often is with the definition of
+@FPTOOLS_TOP_ABS@: this variable is supposed to be the canonical path
+to the top of your source tree, but if your system uses an automounter
+then the correct directory is hard to find automatically. If you find
+that @configure@ has got it wrong, just put the correct definition in
+@build.mk@.
\subsection{The story so far}
\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
You {\em may} need to re-\tr{ranlib} your libraries (on Sun4s).
\begin{verbatim}
-% cd $(libdir)/ghc-2.08/sparc-sun-sunos4
+% cd $(libdir)/ghc-x.xx/sparc-sun-sunos4
% foreach i ( `find . -name '*.a' -print` ) # or other-shell equiv...
? ranlib $i
? # or, on some machines: ar s $i
Workaround: don't put wierd things in string args to \tr{cpp} macros.
\end{enumerate}

-%When configuring the support code (mkworld, glafp-utils, etc.), you

-%\tr{NO_SPECIFIC_VERSION}. This is cool.
-
-
-%------------------------------------------------------------------------
-%\item
-%Sooner or later in your ``make-worlding'' life you will do and see
-%something like:
-%\begin{verbatim}
-% make Makefile
-% rm -f Makefile.bak; mv Makefile Makefile.bak
-%../.././mkworld/jmake -P ghc -S std -I../.././mkworld -DTopDir=../../. -DTopDir=...
-%../.././mkworld/jrestoredeps
-%==== The new Makefile is for: ====
-%make: Fatal error in reader: Makefile, line 850: Unexpected end of line seen
-%Current working directory /export/users/fp/grasp/ghc-0.26/ghc/runtimes/standard
-%*** Error code 1
-%make: Fatal error: Command failed for target `Makefile'

-
-%Don't panic! It should restore your previous \tr{Makefile}, and
-%leave the junk one in \tr{Makefile.bad}. Snoop around at your leisure.
-
-% ------------------------------------------------------------------------
-%\item
-%If you do corrupt a \tr{Makefile} totally, or you need to glue a new

-\item
-Don't configure/build/install using a variety of machines. A
-mistake we've made is to do \tr{make Makefiles} on a Sun4, then try to
