IXEMUL LIBRARY INSTALLATION NOTES
(last updated 10/4/95)
=====================
DISTRIBUTION CONTENTS
=====================
The net ixemul library distribution consists of several archives, where XXYY
are the major and minor version numbers:
ixemulXXYY-bin.lha utils for gnu/bin, like ixtrace and ixconfig
ixemulXXYY-sdk.lha files needed to build ixemul.library using apps
ixemulXXYY-doc.lha various documentation, such as this file
ixemulXXYY-src.lha Complete source code for ixemul library
ixemulXXYY-CF.lha Specific flavors of the library, where 'C'
is one of 0, 2, 3, or 4, for 68000, 68020,
68030, and 68040 respectively, and 'F' is either
'f' or 's' for FPU support or soft floating point
respectively.
Note that version 41.0 would be 4100 and 41.10 would be 4110.
The ixemulXXYY-doc.lha archive contains various readme and copyright files
that do not need to be installed anywhere. The ixemulXXYY-src.lha archive
contains the source tree that can be installed anywhere. The rest of the
archives should simply be extracted relative to the gnu: directory to put
all the files in their standard location.
========================
INSTALLING RUNTIME FILES
========================
For the moment, you must manually install the files. Eventually there will
be an installer script available that you can use with the standard AmigaDOS
installer program to make installation more WorkBench friendly.
First backup any files in gnu: that will get overwritten during the install,
if you wish to preserve them. These files typically are:
gnu:bin/ixconfig
gnu:bin/ixtrace
gnu:lib/bcrt0.o
gnu:lib/crt0.o
gnu:lib/rcrt0.o
gnu:lib/libc.a
gnu:lib/libb/libc.a
gnu:include (lots of files, but probably not all)
gnu:man (lots of files, but probably not all)
gnu:Sys/libs/ixemul* (all the old versions of the library)
Extract the contents of ixemulXXYY-bin.lha, ixemul-XXYY-sdk.lha (if you
expect to be building any ixemul.library using applications), and any
ixemul-XXYY-CF.lha archives that you want, overwriting any existing copies
of the files in your gnu tree. For example, to install the utils, sdk, and
both the 68000 and 68040+68881 versions of the library, do the following:
lha -mraxe x ixemulXXYY-bin.lha gnu:
lha -mraxe x ixemulXXYY-sdk.lha gnu:
lha -mraxe x ixemulXXYY-0.lha gnu:
lha -mraxe x ixemulXXYY-4f.lha gnu:
Now you need to decide which version of the library to use, based on what
sort of machine you have (68000, 68020, 68030, 68040) and whether or not it
has an FPU (68020+68881, 68030 with FPU, or 68040 with FPU). Do something
like the following:
cd gnu:Sys/libs
copy ixemul040fpu.library ixemul.library clone
Then either reboot or run a program to flush the existing ixemul.library (if
any) from memory.
=======================
INSTALLING SOURCE FILES
=======================
To extract the source code, simply cd to a directory where you would like
the source code directory to be created, and extract the source archive
there:
cd gnu-src:
lha -mraxe x ixemulXX.YY-src.lha
Note that this will create the directory ixemul-XX.YY and populate it with
all the source files.
To rebuild the library, all that is needed is to run the configure script
and then run make. Note that at the moment, you have to use separate build
and source directories and the path you use to run "configure" has to be
an absolute one, not a relative one (see below). That is, you leave the
source tree untouched and create a separate build tree in which all the
compiled files will be placed:
cd gnu-build:
makedir ixemul-XX.YY (must not be source directory at the moment)
cd ixemul-XX.YY
sh /gnu-src/ixemul-XX.YY/configure m68k-cbm-amigados
This will create a Makefile and several subdirectories with other Makefiles.
Note the section in the Makefile that looks like:
all:
$(MAKE) build CPU=68000 FPU=soft-float BASE=no-baserel
$(MAKE) build CPU=68000 FPU=soft-float BASE=baserel
$(MAKE) build CPU=68020 FPU=68881 BASE=no-baserel
$(MAKE) build CPU=68020 FPU=68881 BASE=baserel
$(MAKE) build CPU=68020 FPU=soft-float BASE=no-baserel
$(MAKE) build CPU=68020 FPU=soft-float BASE=baserel
$(MAKE) build CPU=68030 FPU=68881 BASE=no-baserel
$(MAKE) build CPU=68030 FPU=68881 BASE=baserel
$(MAKE) build CPU=68030 FPU=soft-float BASE=no-baserel
$(MAKE) build CPU=68030 FPU=soft-float BASE=baserel
$(MAKE) build CPU=68040 FPU=68881 BASE=no-baserel
$(MAKE) build CPU=68040 FPU=68881 BASE=baserel
@(cd libsrc && $(MAKE) $(FLAGS_TO_PASS))
By default, all of the versions of ixemul.library are build by make. This
can take a very long time (about a day on a 40MHz 040 WarpEngine for
example, probably much longer on other machines).
If you only want to build one particular version of the library and runtime
files to test, just comment out the lines you don't want. I.E. to build a
68040+68881 version, the above lines should be changed to:
all:
$(MAKE) build CPU=68000 FPU=soft-float BASE=no-baserel
$(MAKE) build CPU=68000 FPU=soft-float BASE=baserel
# $(MAKE) build CPU=68020 FPU=68881 BASE=no-baserel
# $(MAKE) build CPU=68020 FPU=68881 BASE=baserel
# $(MAKE) build CPU=68020 FPU=soft-float BASE=no-baserel
# $(MAKE) build CPU=68020 FPU=soft-float BASE=baserel
# $(MAKE) build CPU=68030 FPU=68881 BASE=no-baserel
# $(MAKE) build CPU=68030 FPU=68881 BASE=baserel
# $(MAKE) build CPU=68030 FPU=soft-float BASE=no-baserel
# $(MAKE) build CPU=68030 FPU=soft-float BASE=baserel
$(MAKE) build CPU=68040 FPU=68881 BASE=no-baserel
$(MAKE) build CPU=68040 FPU=68881 BASE=baserel
@(cd libsrc && $(MAKE) $(FLAGS_TO_PASS))
Note that you have to build the 68000 version in any case, since the
compiler runtime files (*crt*.o, libc.a, libbc.a) are generic 68000 code.
Then just run "make" in the build directory:
cd gnu-build:ixemul-XX.YY
make

REPORTING BUGS
==============
Please report problems or bugs to Fred Fish (fnf@amigalib.com), who is the
current ixemul library coordinator. Even better than a bug report is a bug
fix, which typically would be a context diff file for one or more ixemul
source files.
