patching Network-NineP

System: Microsoft Windows XP Home Edition
CPUs: Intel(R) Atom(TM) CPU N270 @1.60GHz
Deps: HaskellPlatform-2014.2.0.0-i386-setup.exe

I am suspending further work on this project after initially
patching the hackage download to compile on GNU/Linux,
basically because I don't like the [MSYS2] toolchain that's
shipped with the current HaskellPlatform.

The GitHub network-ninep-0.0.1 download contains code using withSocketsDo,
purportedly needed to be able to use Winsock - I believe binary >0.6.0.0 might be
a dependency for that download, however withSocketsDo is not appearing in the
hackage Network-NineP downloads, of which incidentally, though I admit I have
not researched it thouroughly, if the GitHub release preceded those from hackage,
some of the former's code might appear to have been split off into separate NineP
downloads: https://github.com/Elemir/network-ninep

The Network-NineP-0.4.1 package compiled on Slackware-14.0 after
adding this line following the comments at the top of Error.hs. If you are
installing into '--prefix=/usr' you might want to change the executable's
name in the cabal file, so it does not conflict with Slackware's /bin/test,
/usr/bin contains a symbolic link to /bin/test.

{-# LANGUAGE DeriveDataTypeable #-}

On Windows XP the compile fails on the 8th of a total of 9 files,
the same occurs on HaskellPlatform-7.10.2-a-i386-setup.exe.

HaskellPlatform-7.10.3-i386-setup.exe installed on XP fails to
load time-1.5.0.1.

HaskellPlatform-8.0.2-full-i386-setup.exe requires at minimum
Windows 7, as that version's ghc.exe uses the procedure entry
point _wsplitpath_s, introduced in the Windows 7 msvcrt.dll.

After importing Network (from network-2.4.2.3) in ghci.exe
the 'Not in scope' error occurs.

patching sexpr

System: Slackware Linux (version 14.0)
CPUs: Intel(R) Atom(TM) CPU N270 @1.60GHz
Deps: ghc-7.8.4-i386-unknown-linux-deb7.tar.xz

This entry is not finished yet.

Looking at /sexpr-0.2.1/Codec/Sexpr/Internal.hs it appears feasible to patch
sexpr-0.2.1.tar.gz to use QuickCheck2, to run on a bootstrapped ghc and/or
on HaskellPlatform.

With the QuckCheck version I have installed being 2.7.6,
running a SlackBuild script I authored for the above sexpr
version outputs the following, owing to the sexpr version
being written for QuickCheck <2.1.

patching ESS

System: Slackware Linux (version 14.0)
CPUs: Intel(R) Atom(TM) CPU N270 @1.60GHz
Deps: ess-16.10.zip, cl-lib-0.6.1.el,
julia-emacs-master.zip

The development version with the below patches and
others committed is available as a github clone and/
or download, the latter as ESS-master.zip. 

Looking at the release notes for emacs-24.3 it appears feasible to patch ess-16.10 to
run on Slackware 14.0 (or other Un*x distros) with emacs-24.2.

http://lists.gnu.org/archive/html/info-gnu-emacs/2013-03/msg00001.html

" ...An update for the Common Lisp emulation library."
" ...the changes in Emacs 24.3 are relatively minor."

https://ftp.gnu.org/gnu/emacs/
emacs-24.3.tar.gz

Read about the update.

bash-4.2# cd /tmp

bash-4.2# grep -n "Common Lisp emulation" emacs-24.3/etc/NEWS
247:** Common Lisp emulation (CL)
bash-4.2#

bash-4.2# head -n 258 emacs-24.3/etc/NEWS | tail -12
** Common Lisp emulation (CL)

*** CL's main entry is now (require 'cl-lib).
`cl-lib' is like the old `cl' except that it uses the namespace cleanly;
i.e., all its definitions have the "cl-" prefix (and internal definitions
use the "cl--" prefix).

If `cl' provided a feature under the name `foo', then `cl-lib'
provides it under the name `cl-foo' instead; with the exceptions of the
few `cl' definitions that had to use `foo*' to avoid conflicts with
pre-existing Elisp entities.  These have been renamed to `cl-foo'
rather than `cl-foo*'.
bash-4.2#

Check for any new macros.

Patches committed on 10, 14, and 18 January 2017, respectively for a backwards
compatibility definition for defvar-local, allocation for pcase.el (emacs-24.2/24.1)

defines based on those found in the file emacs-24.3/lisp/subr.el.

'gcc_fullbuild' - found after extracting gcc4.2.tgz - which contains these prerequisite programs
with version numbers, for compiling gcc-4.2.0; this file is available in the sidebar as the down-
load is 473 MB; I've added indent (a flex dependency) and omitted gettext-0.16 in the below.

These compile favourably utilising CFLAGS="-O2 -march=i586", and the configure script

The following command run in the source directories - if one builds within the source tree -
will strip to external PDB the compiled executables and libraries.

$ find . | xargs file | grep "executable" | grep PE | cut -f 1 -d : | \
> xargs strip --strip-unneeded 2> /dev/null
$

Remove or rename /bin/make and move GNU make to /bin, then add a symbolic link as
gmake, remove or rename /bin/m4 and move GNU m4 to /bin, remove or rename /bin/sed
and move GNU sed to /bin, before running 'gmake install' on bison-2.3 rename or remove
/bin/yacc and rename or remove /usr/lib/liby.a, which can be replaced by the bison version,
and before running 'gmake install' on flex rename or remove /bin/lex; the file /usr/lib/libl.a
(the lex library) can likewise be removed or renamed.

The shell es-0.9.1.tar.gz will then compile on gcc-3.3 after deleting
the '-Wno-missing-field-initializers' and '-Wno-clobbered' CFLAGS
from the configure script's generated Makefile.

$ echo $CC
/opt/gcc.3.3/bin/gcc
$ cd es-0.9.1
$ CFLAGS="-O2 -march=i586" \
> ./configure --prefix=/usr \
> --build=i586-pc-interix3 \
> --host=i586-pc-interix3

...

Edit your Makefile (as above).

$ gmake

...

$ find . | xargs file | grep "executable" | grep PE | cut -f 1 -d : | \
> xargs strip --strip-unneeded 2> /dev/null

$ mv es /bin
$ exit

NB: These installation instructions don't allocate for a line-editing library;
for some reason compiling with readline-6.1 results in dead Æ, Ø and Å
keys. Haahr's .esrc in the examples directory in part pertains to a NeXT
machine, and Jamesh's .esrc file likely won't work without a line-editing
library. However, starting SFU/SUA's Korn shell inside GNU emacs and
then switching to es is satisfactory.

(setq explicit-shell-file-name "C:\\WINDOWS\\system32\\posix.exe")
(setq explicit-posix.exe-args '("/u" "/c" "/bin/ksh" "-l"))

The es(1) and xs(1) man pages are similar.
