X INSTALLATION
X
X
XThis document explains how to compile and install the zoo archiver.
X
XGenerally, you will not build zoo by directly invoking the supplied
Xmakefile. Instead, you will execute one of the supplied scripts, or
Xcreate a suitable script. Each supplied script has a name beginning
Xwith the characters "mk" and is executed with the command
X"sh scriptname" or "csh scriptname". All the scripts listed below
Xworked correctly with version 1.50 of zoo. All of them except mkx68 and
Xmkx86 are also known to work correctly for versions 1.71, 2.00, and
X2.01.
X
Xmksysv This is for any system running System V Release 2 or something
X reasonably compatible. It is known to work on the *T&T **IX
X PC (also known as the 3B1 or the *T&T 7300) running software
X revision 3.0. It should also work on more recent versions of
X Xenix. On older machine architectures this script may need to
X be revised to add a `-Ml' switch or equivalent to cause the
X large memory model to be used. For Microport System V/AT and
X Xenix see also descriptions for mkuport, mkx86, and mkx68.
X
Xmkbsd This is for 4.3BSD. It is known to work on a VAX-11/785 run-
X ning 4.3BSD straight from Berkeley.
X
Xmkuport For Microport System V/AT. This script includes the -Ml
X switch so that the large memory model is used.
X
Xmkx68 This script is for Xenix/68000. It is known to work with zoo
X version 1.50 on a Radio Shack Model 16 running Xenix version
X 3.01.01. It takes care of problems in the C compiler and in
X the include files related to incorrect handling of the `void'
X data type. However, since this version of Xenix does not have
X the memset() library function, the line "#define MEMSET" may
X first need to be commented out from the group of symbol defin-
X itions for SYS_V in the file ``options.h''. You may also need
X to add the switch "-F 6000" (or some other reasonable value
X instead of 6000) to the loader to make it allocate a bigger
X stack.
X
Xmkx86 This script is for Xenix for 80286 systems. It is known to
X work (for zoo version 1.50) on an Intel 310/286 running Xenix
X 3.4 and an AT running SCO Xenix 2.2. It causes the large
X memory model to be used and sufficient stack space to be allo-
X cated at load time.
X
Xdescrip.mms This is a makefile suitable for use on VAX/VMS systems with
X DEC's version of make, called MMS. It is believed to work on
X versions 4.5 through 4.7 of VAX/VMS. The target zoo.exe
X directs the linker to use the file options.opt so that the
X shareable library is used. The target zoobig.exe is identical
X except that the shareable library is not used, making the exe-
X cutable program about twice as big.
X
X Special techniques are needed to work around numerous pecu-
X liarities in VAX/VMS. These are described separately in the
X file ``vmsbugs.doc''. In particular, the VAX/VMS version of
X zoo must be used in conjunction with the "bilf.exe" utility,
X which performs needed file conversions. The source program
X bilf.c is included in the current source distribution for zoo.
X
XThe file ``options.h'' defines preprocessor symbols for the various sys-
Xtems. In most cases, given a reasonably powerful C compiler and
Xlibrary, you will be able to find a combination of options that will
Xwork. Documentation for these options is in the file ``options.doc''.
X
XOther machine-dependent code and definitions are in machine.h,
Xmachine.c, and portable.h. Also, the amount of memory used for various
Xarrays can be customized by defining symbols that are described and used
Xin zoomem.h.
X
XThe low-level input/output routines are in portable.c. In most cases
Xthese will not need to be modified.
X
XThe zoo source code largely conforms to the requirements of Kernighan
Xand Ritchie's book. Some exceptions are as follows.
X
X - Variables are believed to be unique in their initial 8 characters.
X Systems that distinguish fewer than 8 initial characters are
X currently not supported.
X
X - Zoo code assumes that members of structures do not have global
X scope.
X
X - Long preprocessor symbols are occasionally used.
X
X - The special value -1 is cast to a pointer of type (FILE *) to pro-
X vide a distinguished file pointer that is used to signify output to
X a null file. This should work on most systems that support the
X system call sbrk. Any suitable value may be supplied in place of
X -1 in zooio.h.
X
XTROUBLESHOOTING.
X
XAs currently configured for **IX variants, zoo uses the access() system
Xcall to check for file existence (see the definition for the symbol
XEXISTS in options.h). There is some question about the appropriatenes
Xof this, because access() can give the wrong answer when used from a
Xset-user-id program. If EXISTS is left undefined, zoo uses its own
Xfunction to test for file existence by trying to open the file for read
Xand also for write.
X
XTwo common reasons for crashes when zoo is executed are the following.
X
X - On machines with older (Intel-style) architectures zoo requires the
X large memory model. Compiling with the small memory model will
X cause problems. Also, systems that are limited to 64 kilobytes of
X data and 64 kilobytes of code are not currently supported (but they
X will be in the future).
X
X - A generous amount of stack space is needed. Depending on the sys-
X tem, this will vary from about 15 kilobytes to about 33 kilobytes.
X On systems that cannot expand the stack dynamically you will need
X to specify the size of the stack area at load time.
X
XSPECIAL VERSIONS. A version (currently 2.01) is available for MS-DOS
Xthat provides better performance due to assembly language routines and
Xalso includes some system-dependent features. Another version
X(currently 2.00) has been ported by J. Brian Waters for the Amiga. It
Xincludes several AmigaDOS-dependent features such as preservation of
Xfile times and wildcard expansion.
X
XEXTRACT-ONLY VERSIONS. For a new system, your first concern should be
Xthe ability to extract and list zoo archives. For this purpose try com-
Xpiling booz (which stands for Barebones Ooz) (currently version 1.01),
Xwhich can be compiled with three different options requiring different
Xdegrees of compiler sophistication and offering different levels of
Xfeatures. Unlike zoo, booz will work on systems with less than 64 kilo-
Xbytes of total available memory. However, unlike zoo, booz uses low-
Xlevel unbuffered file descriptors in **IX style. This program is not a
Xpart of the standard zoo distribution, because nobody has ever shown any
Xinterest in it.
X
XMachine-dependencies.
X
X - Currently the only systems supported are those that can read and
X write in 8-bit units. The file ``machine.h'' contains a typedef of
X BYTE, and it must be defined to be an 8-bit quantity.
X
X - It is not known whether zoo code as it stands will work on a 1's-
X complement machine.
X
X - The code assumes that type `int' is at least 16 bits long and type
X `long' is at least 32 bits long. There may be some implicit
X assumptions that type `char' is exactly 8 bits; I am not sure if
X this is so. However, type `BYTE' must be exactly 8 bits long.
X
X - In accordance with K&R (p 126), zoo code assumes that sizeof(char)
X equals exactly 1.

X some kind of stack exception (e.g. if the hardware maintains tag
X bits in each word on the stack and doesn't allow certain types of
X data to be arbitrarily accessed). This is just a theory so far.
X
X (b) Parameter passing relies on consecutive small parameters being
X properly interpreted as a single larger parameter when needed.
X Eventually var_args should be used, but not all systems probably
X have it at the moment.
X
X (c) All messages, whether informative or error, are sent to standard
X output via printf. It might be a good idea to eventually send 'e' and
X 'f' class messages to the standard error stream. Best would be
X some way of telling if standard output and standard error are not
X the same device, so that we could always send error messages to
X standard error, and also duplicate them to standard output if
X different from standard error. There seems to be no way
X of doing this in the general case.
