Building ghdl mcode version

This is a script called build_distribution. With minor modifications (the make target) it can
be used to build either a 32 bit Linux or OS X ghdl mcode version. You can extract parts to build incrementally. By default it removes source files when done. This can be prevented by using a command line argument: build_distribution --keep-build

There may be a default issue with warnings as errors in gnat that can cause an issue with too long of lines in default_pathes.ads. This has been resolved as of 29 December 2013.

If you need an earlier revision you can deal with this by building from close to root (e.g. in /opt) or turning off the error as warning flag. This comes about from general sweeping up of style warnings in gnat, which when enabled (and they are) limit source to something that would fit on 80 column punch, presumably for use in formal verification.

The gnat version was incorrectly specified and has been updated:

#!/bin/sh -v
# accepts one argument '--keep-build', otherwise strips down executable to
# quintessential content.

# The ghdl mcode version can be built on Windows, Linux and OS X.  The two
# latter are described herein.

# Prerequisites:

# The mcode ghdl version currently only builds for a 32 bit target.  The 
# easiest way to do this is to use a 32 bit build environment. Using a
# 64 bit build environment for a 32 bit target is outside the scope of
# this description.  You could note some 64 bit Linux distributions may not 
# natively support running 32 bit executables.
# 
# To obtain a 32 bit GNAT/gcc toolsuite for building ghdl_mcode on OS X you
# could use  http://www.macada.org/macada/Downloads_files/Gnati386-4.3-xcode3.0.dmg
# from http://www.macada.org/macada/Downloads.html  For OS X and this GNAT
# you want /usr/local/ada4.3/bin to appear before any other gcc in your 
# PATH.  This builds with the supplied GNAT and gcc both targeting a 32 
# result.
# 
# This is the version I use.
# 
# The easy way to build on Linux is using a 32 bit distribution, I have
# built recently with lubuntu 12.10 as a VM under VirtualBox.  You obtain
# gcc and ada for it.  ghdl_mcode by itself isn't particularly pick  as to 
# versions, the OS X GNAT tools are from 2008.

# Notes:
# This script build relative to it's invocation location, generating a sub
# directory ./ghdl.  There is a dependency between the build location and the
# VHDL library installation location that tells us to keep the build directory
# when done, and link to the executable.  ./ghdl/translate/ghdldrv/ghdl_mcode,
# typically linked to /usr/local/bin/ghdl, and ./doc/ghdl.1 typically linked to
# /usr/local/man/man1/ghdl.1.  Non adminstrative installation would probably
# link to $HOME/bin and $HOME/man/man1 (which don't normally exist).

# undefined full paths for svn, gnatlink, cd, echo and exit may be builtin

# ghdl (mcode) is relocatable.  You can link from the stripped build directory
# or mv the remains to an 'install' location.

# You can extract or comment out parts of this script to allow customization
# or debugging.

# Build:

# umask 022 so we don't have to fight over permissions
# we do this with trepidition but in the knowledge we are only 
# writing to expendable locations

echo directory $PWD
umask 022

#if the name ghdl currently exists delete it, file or directory

if [ -e ghdl ] 
then
  /bin/rm -rf ghdl
fi

# either from distribution install directory (e.g. /usr/local ) or
# build in distribution  (mkdir build; cd build; e.g. /usr/local/ghdl/build)

# Get ghdl source:

# From ghdl-updates:
hg clone http://hg.code.sf.net/p/ghdl-updates/code ghdl
# Can be specified by revision:
# hg clone -r145  http://hg.code.sf.net/p/ghdl-updates/code ghdl
# revision -r145 known to work

# From gna.org Subversion repository:
# svn -r 150 co svn://svn.gna.org/ghdl/trunk ghdl

# Example from local copy of repository instead of Subversion:
#
#/bin/cp -r /$HOME/Desktop/ghdl1/ghdl_revision_150 ghdl
# the above cp -r may generate errors for unfilled symbolic links to .o files
#  this is okay
#
# \cd ghdl/translate/ghdldrv
# echo directory $PWD
# make clean
#cd ../../..
# echo directory $PWD

# deny write access to group/other

/bin/chmod go+rx ghdl
/bin/chmod -R go+r ghdl
/usr/bin/find ghdl -type d -exec chmod go+x \{\} \;

# build

cd ghdl/translate/ghdldrv

/bin/rm -f ortho_code-x86-flags.ads

# if the link is there:
/bin/rm -f ghdl

# Insure ADA and gcc versions are compatible and exist
# There is no checking.  I'd suggest keeping the build environment
# if you aren't clear on this

# Mac OS X
# /usr/bin/make target=i686-darwin GNAT_LARGS=-Wl,-no_compact_unwind

# Linux (default)  (i386)

/usr/bin/make target=i686-pc-linux-gnu

# for Mac OS backward compatibility (out of date):
# relink ghdl_mcode as a Mac OS X 10.5 SDK target if built on Mac OS X 10.6:
#
#export MACOSX_DEPLOYMENT_TARGET=10.5
# (the above variable may not be needed to build a 10.5 SDK target)
#
# gnatlink ghdl_mcode.ali -g memsegs_c.o chkstk.o i386.o linux.o times.o grt-cbinding.o grt-cvpi.o -lm -isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5 --no_compact_linkedit
#
# This requires the older SDK which is used to span OS X 10.5 - 10.9 use.
