Macintosh porting of R
======================
In this directory you can find all the files needed to compile a
version of R for MacOS. The original code for MacOS was written by
Ross Ihaka, Julian Harris and Wing Kwong (Tiki) Wan. More recently
Stefano M. Iacus has written new code, modified or simply updated most
of the older files to work with current versions of R sources and the
Waste Text Engine.
From version 1.2.3 R is a Carbon application that will run natively
under MacOS X System.
BUILDING R WITH APPLE'S MPW ENVIRONMENT:
----------------------------------------
This note explains how to:
* build R binary via MPW
* build packages and modules via MPW
* build help files
* build R binary via CodeWarrior
Before you continue please assure that your installation
fits the following requirements:
REQUIREMENTS:
-------------
0) MPW release August 2001 + updates. Go to
http://developer.apple.com/tools/mpw-tools
and follow the instructions.
1) a copy of MacPerl (www.macperl.org) and install it
for MPW. Just run the "Install.MPW_Perl" that you
find the MacPerl distribution root folder.
This is needed to build help/latex/etc files
Please read the instructions on how to increase
memory to the MPW shell.
2) a copy of the "f2cLib" runtime library.
You can find it at
http://www.ci.tuwien.ac.at/~iacus/R
or from the standard R distribution
This is needed to build and run R and to
build modules and packages that contain
fortran code.
3) you should have a copy of the "f2c" MPW tool in the
Tools directory of your MPW installation.
You can have a copy of it at:
http://www.ci.tuwien.ac.at/~iacus/R
This is needed to convert source code from fortran to C
4) you also need the "sed" MPW tool. You should have
a copy of it at
http://www.ci.tuwien.ac.at/~iacus/R
5) A copy ofthe package "MoreFiles 1.5.2" or later.
This is usually distributed along with the Carbon SDK
kit (developer.apple.com)
6) A copy of the Waste 2.x distribution. Please refer to the
official Waste site:
http://www.merzwaren.com/waste
7) a copy of the "zlibLib" runtime library.
You can find it at
http://www.ci.tuwien.ac.at/~iacus/R
or from the standard R distribution
This is needed to build and run R.
Starting from version 1.3.1 we are switching to Apple's MPW
compiler to build R and its packages and modules.
You will still find Metrowerks CodeWarrior project files
but these will be shortly discontinued.
General advice:
It can happen that some scripts don't work.
This should be to some line-endings problems. If you encounter
any of this problems, please convert script-files to have
MacOS line-endings.
This could be generated by stuffit expander when you uncompress
the R source archive.
Definition:
"R_HOME" the main root of R sources, say ::: from
the folder where the files you are reading is.
Step by step instructions
-------------------------
0) Fit all the requirements !
1) Open MPW shell and change the directory to the folder where this
file is.
execute MPWBuild
from the MPW shell. MPWBuild is a script file that is charged of
creating of a makefile for the MPW shell called "MakeR" that is
based on you configuration.
MPW_Build make copies of "f2cLib", "zlibLib" and "WasteLib" to
the R_HOME folder.
2) To build R you simply write on the MPW shell the following two
lines:
Make -f MakeR R > MyMake
MyMake
MyMake is charged to do many things:
+ Generates the files: Rconfig.h, Rversion.h, FFDecl.h,
FFTab.h and res:RVerDefs.h
+ Moves config_mac.h to ::include:config.h
+ Duplicates your copy of "f2cLib" to R_HOME
+ Duplicates your copy of "zlibLib" to R_HOME
+ Duplicates your copy of "WasteLib" to R_HOME
+ Builds R binary
3) When you are done you can execute Makefile.mac.
a) type "Make -f Makefile.mac" and execute it in the MPW Shell.
b) select the output and run it. This will take some time
because of building of help files.
4) You can now build packages and libraries.
Change MPW Shell directory to R_HOME:src:library
Execute "BuildAll.mac"
If all went right you can build modules.
Change MPW Shell directory to R_HOME:src:modules
Execute "BuildAll.mac"
5) To build help files just type the following commands
Make -f Makefile.mac > build
build
The tools Folder:
-----------------
Some MPW scripts that are useful to build
packages and to generate some of the files R needs to
be built (independently from the compiler you use).
In particular:
GETVERSION : MPW script that generates "Rversion.h"
and "res:RVerDefs.h"
FF_CREATE : MPW script that generates "FFTab.h" and
"FFDecl.h"
GETDESC : fixes DESCRIPTION.in files
GETCONFIG : MPW script that generates "Rconfig.h"
both need the "sed" MPW tool installed.
SUMMARY OF MPW BUILD COMMANDS:
------------------------------
move first to src/macintosh dir, then you can just copy
the following lines in the MPW Worksheet:
MPWBuild # prepares the main makefile
Make -f MakeR R >MyMake # generates commands
MyMake # builds R binary
Make -f Makefile.mac > build # prepares commands for help
build # builds help files
Directory ::library
BuildAll.mac # builds all library binaries
Directory ::modules
BuildAll.mac # builds all modules
Directory ::macintosh
:::R # launches R
Where to find things:
---------------------
as for now, you can find most of the things you probably miss
at this URL
http://www.ci.tuwien.ac.at/~iacus/R
(contains "sed", "f2cLib", "zlibLib", ...)
One other good place to look for Unix-like tools for MPW is also
ftp://sunsite.cnlab-switch.ch/software/platform/macos/src/mpw_c
BUILD R WITH CODEWARRIOR:
-------------------------
Even if we are going to discontinue CodeWarrior support,
you can still build the R binary using the CWPro 7 Project
file in the folder src/macintosh/cwpro.
Anyway, take care that this project file conflicts with the
following files
src/library/base/R/windows/dialogs.R
library/R-ex/Script.r
you should either rename or remove these files.
If all went fine, CodeWarrior will create the binary
R.cw in the root folder of R source tree.
Libraries, modules and help files have to be built
using MPW. In order take make this work you have to
rename "R.cw" as "R".
