OpenZz 1.0.4-4ce2
This is OpenZz 1.0.4-4ce2, a fork of the original OpenZz distribution, based on OpenZz version 1.0.4-4. The original README can be found at the end of this Markdown file, encased in a preformatted text block.
This fork was made because development on OpenZz was stalled, I have a
project (Zzrk) that requires OpenZz,
and, at some point, I was unable to build it on the then-current version
of gcc
. Shortly thereafter, upgrades to the build system also caused
problems; it seemed like libtool
was now causing automake
to generate Makefiles which went into infinite loops at the shell level;
pstree
showed what looked like an infinite tree of sed
and bash
.
This would take down my laptop quite readily.
It was at this point I decided to create the first version of this fork.
1.0.4-4ce1
In 1.0.4-4ce1, I added a simple build.sh
script to build the ozz
executable directly, without messing around with libtool
or anything.
It works on Ubuntu and NetBSD, and will, I'm sure, work on other flavours
of Linux and other BSDs with little or no modification.
Running build.sh
is recommended. Run autogen.sh
and configure
at
your own risk.
Note, though, that several of the tests now fail. The core semantics of OpenZz seem alright, so these failing tests have been skipped in the test suite. The specific failures are:
deref_param.zz
: badly-written test; it shouldn't be caring about an internal address, which isn't stable from run to runlist_in_cond.zz
: the syntaxa.b
seems to be a syntax errornumerictypes.zz
: 64-bit values wrap to 32 bits on a 32-bit architecturetagdtor.xx
: can't open the specified.so
file
The double.zz
test also did not pass.
The verdict from those results was that this version of OpenZz does not support:
- 64-bit integer values
- doubles
- the
a.b
syntax (whatever that means exactly) - loading
.so
files
Which was fine by me, as it can still play Zzrk.
Later on, I discovered that ozz
had problems when compiled on a
64-bit system. For the longest time I was only thinking about how it runs on
The Cat's Eye Technologies' Platform,
where it runs just fine, because it's a 32-bit architecture.
But at some point I noticed it didn't work on 64-bit systems anymore,
and I did eventually care enough to try to fix it. This led to the
second release of this forked project.
1.0.4-4ce2
In 1.0.4-4ce2, I made some changes to the build script to force
compilation as a 32-bit executable. This is done by passing
the -m32
flag to gcc
. For more information,
see e.g. this StackOverflow question
For this to be successful, 32-bit headers must be installed on the system. On Ubuntu, this can be accomplished with:
sudo apt install gcc-multilib
For more information, see e.g. this StackOverflow question
This will also require 32-bit versions of the libraries that ozz
links to. Under Ubuntu, they can be installed with:
sudo dpkg --add-architecture i386
sudo apt update
sudo apt install libc6:i386 libedit-dev:i386
For more information, see e.g. this StackOverflow question
Also, under the recent 32-bit build that I made using these
modifications, for whatever reason, the double.zz
test now passes.
Which is fine by me, as long as it can still play Zzrk.

Zz - Dynamic Lexical Parser README File
===============================================================================
Zz is a dynamic parser which is currently being developed as a front end to
gcc to implement compilation of new languages (ie. TAO and others), for APE
systems. These are custom build parallel processing computers used for LQCD
physics research.
See:
http://chimera.roma1.infn.it/ape.html
UPDATES
See the NEWS and ChangeLog files for information on the latest changes
Some support is being formulated at the project directory on SourceForge:
http://openzz.sourceforge.net

The Zz library is released under the GNU Lesser GPL (LGPL).
Parts of Zz are released under the GPL - see the "COPYING" file in the
project root.
DOCUMENTATION

APE
Whence the name "APE"? "Ape" is the Italian word for "bee", the mascot of
the APE project. (INFN, the funder of the project is based in Italy and the
software is primarily developed there).
