on GHC yourself.
-A source distribution contains complete sources for the @fptools@
-suite. Not only that, but the more awkward machine-independent steps
-are done for you. For example, if you don't have @flex@<ncdx/flex/
-you'll find it convenient that the source distribution contains the
-result of running @flex@ on the lexical analyser specification. If
-you don't want to alter the lexical analyser then this saves you
-having to find and install @flex@. You will still need a working
-version of GHC on your machine in order to compile (most of) the
-sources, however.

We make source distributions more frequently than binary
distributions; a release that comes with pre-compiled binaries
Source-only distributions are either bugfix releases or snapshots of
current state of development. The release has undergone some testing.
-Source releases of 3.xx can be compiled up using 2.10 or later.
-Compiling with version 0.29 won't work any more: we use Haskell 1.4
-features in the compiler.

<tag/Build GHC from intermediate C @.hc@ files<nidx/hc files/:/ You
need a working GHC to use a source distribution. What if you don't
you will need to install every utility so that you can build all the
derived files from scratch.
-Giving you access to the repository entails some systems administration
-at our end; and we are a bit nervous about being submerged in bug reports
-about our current working copy (which is, by definition, in flux). So
-we are a bit cautious about offering CVS access. Feel free to ask though!

+NOTE: as of version 4.00, we lost a few ports. All of the x86 ports

<item> In compiling the compiler proper (in @compiler/@), you <em/may/
get an ``Out of heap space'' error message. These can vary with the
vagaries of different systems, it seems. The solution is simple:
-(1)~add a suitable @-H@ flag to the @<module>_HC_OPTS@ @make@ variable
-in the appropriate @Makefile@; (2)~try again: @gmake@. (Section~<ref
-id="sec:suffix" name="Pattern Rules and Options">.)
-Alternatively, just cut to the chase scene:
-<tscreen><verb>
-% cd ghc/compiler
-% make EXTRA_HC_OPTS=-H32m # or some nice big number
-</verb></tscreen>
+<itemize>
+<item> If you're compiling with GHC 4.00 or above, then the
+<em/maximum/ heap size must have been reached. This is somewhat
+unlikely, since the maximum is set to 64M by default. Anyway, you can
+raise it with the @-optCrts-M<size>@ flag (add this flag to
+@<module>_HC_OPTS@ @make@ variable in the appropriate @Makefile@).
-<item>
-Not too long into the build process, you may get a huge complaint
-of the form:
+<item> For GHC < 4.00, add a suitable @-H@ flag to the @Makefile@, as
+above.

+
+and try again: @gmake@. (see Section~<ref id="sec:suffix"

GHC's sources go through @cpp@ before being compiled, and @cpp@ varies
a bit from one Unix to another. One particular gotcha is macro calls
like this:
