Note that oleo still generates lots of warning messages. They can usually
be ignored. In patictlar, all the complaints about unreached statements in
eval.c, and the complaints about too-large floating-point numbers can be
ignored.
System Dependent Configuration
If your _doprnt() doesn't correctly interpret %+d you may hve to use the
one from the freed 4.3 BSD sources. (Included.)
If you don't have random(), you will have to use the one from the freed 4.3 BSD
sources. (Also included.)
System configuration options:
-DSYSV
Define this if you are using any version of System Five.
This causes oleo to expect the SysV version of curses and
the SysV terminal driver.
-DNO_UALARM
Define this if your system lacks the ualarm() system call.
-DSETITIMER
Define this if your system lacks ualarm(), but has
setitimer(). (Also define -DNO_UALARM.)
-DNO_RINT
Define this if your C math library does not have the rint()
function. This is needed on most SysV and MSDOS systems.
-DNO_RENAME
Define this if your system lacks the rename() system call.
-DNEED_VPRINTF
Define if your system lacks vprintf(), vfprintf(), and vsprintf(),
but does have a working _doprnt(). If you lack both _doprnt(), and
the v*printf() functions, you'll have to write your own replacements.
-DI_IOCTL
This option causes io_term.c to #include <sys/ioctl.h>, which contains
the information needed to turn on asyncronous IO on HPUX systems.
-DI_STDTYPES
This option causes oleo to include <sys/stdtypes.h>
This is needed on some sunos 4.1 systems.
-DI_STDDEF
This option causes oleo to include <stddef.h> This should be used on
__STDC__ compliant systems.
-DI_SYSTYPES
This option causes oleo to include <sys/types.h>, and should be used
on non-ansi systems.
Compile-time options:
-DA0_REFS
if Oleo is compiled with this option, it will use Visi-Calc
style cell references [A-ZZZ]nnn, instead of the default,
which is Multiplan style RxxCyy.
-DSPLIT_REFS
Instead of using the current reference-counting shared
reference-structures, use a (simpler) (but usually slower!)
one-structure-per-cell scheme. This is usually only for
debugging the spreadsheet.
-DTEST
Include code for debugging-mode, and also include lots of
internal-consistency checks, etc. Defining this usually
doesn't hurt, except on MS-LOS, where every byte counts.
-DUSE_DLD
If you're on a BSD system, oleo can be compiled to
dynamically load the functions that implement
the save-file formats,
spreadsheet formula functions,
spreadsheet keyboard functions,
and the spreadsheet keymaps.
Unfortunately, this code only works on BSD systems.
Before you can use dld with oleo, you will need to apply the
patch found in 'dld.pch'.
If you don't have dld, it can be obtained by anonymous FTP from
prep.ai.mit.edu and probably other archive sites as well.
-DREVERSE
This option causes oleo to reverse the internal representation that
it uses for storing rows and columns. It is intended mainly for
debuggind and performance testing.
-DSMALLEVAL
This option is intended to allow eval.c to compile on MS-LOS machines
where the compiler would otherwise run out of memory.
-DBITS_PER_CELLREF=16
If this option is used, oleo uses 16-bit integers for cell addresses
instead of 8-bit ones. 65535 rows and columns should be more than
enough for most purposes, especially since no 32-bit machine will
have enough virtual memory to fill that region.
To compile on a BSD system:
Decide if you want to use Multiplan style RdigitCdigit or VisiCalc
style LETTERSdigits style cell references. If you prefer the latter, modify
the Makefile to include -DA0_REFS on the CFLAGS line.
If you're using Multiplan style references, find out if you _doprnt()
routine supports %+d correctly. Decimal numbers printed with this format
should have either a + sign (if positive) or a -sign (if negative). If you
_doprnt() is broken, you may be able to use one from the free 4.3BSD
distribution. A copy of that file is included in this distribution.
Find out if your C compiler can handle large switch statements. GCC
(with Gas) can. Some other compilers can't. Some of those that can't
actually bother to tell you that they're producing incorrect code. If your
compiler doesn't, the spreadsheet will crash by branching to a semi-random
location in eval_expression(). If your compiler has this problem, compile
eval.c with the -DSMALLEVAL option.
If you can't get the definitions of __plinf or, __neinf past your
compiler, you may have to resort to assembly language.
Aside from the details above, you should simply be able to type
'make', and oleo should build.
To compile on a MS-DOS system with Turbo C version 2.0:
Copy all the files to your PC.
Convert the files from UNIX ^J terminated lines to MS-DOS ^M^J
terminated lines.
Decide what to do about cell references, as above. Modify
makefile.trc to include -DA0_REFS if appropriate.
Type 'make -f makefile.trc'. This makefile is sufficiently
simple that even Turbo C's wimpy make should be able to deal with it.
To compile on a SYSV system:
Follow the instructions for a BSD system, but include -DSYSV in the
CFLAGS line. Oleo on a pure SYSV system is *not* well tested.
