DarwinPorts is a great project, but I hate using when I don't have to. Mac OS X (at least Tiger does) comes with a readline compatibity already installed - so I have updated these instructions so that you can create a java-readline installation WITHOUT installing DarwinPorts.
The steps are a bit more involved...but here they are:
Download the libreadline-java source from the project site.
Unpackage.
In the source root, edit
Makefile and make the following changes:- Add
JAVA_HOME = /Library/Java/Homebelow the line# Operating system dependent - Make the
JAVANATINCvariable read$(JAVA_HOME)/include - Change
LD_LIBRARY_PATHto beDYLD_LIBRARY_PATH
Now, edit
src/native/Makefile and change the following:- Change the
LIBPATHvariable to be empty - Change the
CFLAGSto-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc -fno-common -DMAC_OS - Change
$(CC) -shared (OBJECTS) $(LIBPATH) $($(TG)_LIBS) -o $@to$(CC) -bundle -flat_namespace -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc $(OBJECTS) $(LIBPATH) $($(TG)_LIBS) -o $@ - change the
JavaReadline_LIBSvariable to be-lreadline -ltermcap
Now, you need to edit
src/native/org_gnu_readline_Readline.c and make the following changes:- On lines 98, 114, 213, and 224, change
#ifdef JavaReadlineto#if defined JavaReadline && !defined MAC_OS - On lines 216, 235, and 475, change
#ifdef JavaEditlineto#if defined JavaEditline || defined MAC_OS
Now, you can run
make, and you will end up with libJavaReadline.so and libreadline-java.jar.Rename
libJavaReadline.so to libJavaReadline.jnilib.Move
libJavaReadline.jnilib and libreadline-java.jar to /Library/Java/Extensions to install it and have it available to all java processes.To test, run
java test.ReadlineTest from the command line.Have fun! Now, you can install HenPlus on Mac OS X easily!
If you are lazy, you can try out the pre-compiled binaries that I have available here - after unzipping, just move the two files (not the entire folder) into your
/Library/Java/Extensions directory. NOTE: these *may* only work on OS X 10.4 and up - I have only tested them on that platform, and they are *not* universal binaries - PPC only.

Has anybody been able to get this to work on an Intel based machine? I followed Nathan's procedure and my `make` spits out this:

javac -d ../build `find . -name "*.java"`

I'm sorry - I don't have an intel-based machine available.
I'd try and look for anything that is out-of-whack on line 101 of the Makefile file. (it reported line 100 in your first post....)
The error: "Makefile:100: *** missing separator. Stop." is the one that tells you what file (Makefile) and line number (:100:) to look for the problem. Beyond that, I really can't help you without access to an Intel machine. (You want to buy me one ;) )
Actually, in looking at the steps, it appears the problem could be in how you edited your Makefile in src/native.
The line number you mention you have an error on corresponds with the line you edit in the third step there:
Make sure that the old line:
$(CC) -shared (OBJECTS) $(LIBPATH) $($(TG)_LIBS) -o $@
Reads:
$(CC) -bundle -flat_namespace $(OBJECTS) $(LIBPATH) $($(TG)_LIBS) -o $@
(all on one line for both of those)
Basically, replace "-shared" with "-bundle -flat_namespace" (no quotes)
Good luck.
I think I'll try and get them compiled as universal binaries....that will probably be the easiest - I can then just post them for download.
I hope to have it in the next couple of days.
OK - so I did the universal binaries...hopefully it's useful to someone.
Thanks for the help Nathan. I think I got your recently released Universal Binaries working. There's a test that comes with the readline source (`java test.ReadlineTest`) that is giving me the appropriate results (a "linux>" prompt). I had to copy libJavaReadline.jnilib to /System/Library/Frameworks/JavaVM.framework/Libraries/ (on OS X 10.4 intel) and add libreadline-java.jar to my CLASSPATH.
I'm needing readline support for running jirb (the interactive ruby interpreter for jruby). when i start jirb i get the following message:
/jruby/jruby-0.9.1/lib/ruby/1.8/irb/completion.rb:187:in `method_missing':NoMethodError: undefined method `completion_append_character=' for Readline:Module
Anybody have any ideas?
I believe this is the same error I was getting before I installed the Universal Binaries for Readline. I'm stuck...
Did it not work if you put the two files into /Library/Java Extensions?
That's where I was able to get it working...You don't even need to modify your classpath or anything...that's *where* you are supposed to put your extensions.
As a general rule, it's a *bad idea* to modify anything in your /System directory...generally it's reserved for "Apple-only" use, and it has a lot different privileges associated with it. That could be part of the issue.
I'll try out jrib - I'm not familiar with it, but I'll see if I can get it going on my machine.
With the Universal binaries (on PPC) in /Library/Java Extensions, I am able to run jirb....I don't know what it does - but I get a "irb(main):001:0>" prompt... :)
Henplus runs on Leopard! I followed the steps above. I left everything as defined, even left /Developer/SDKs/MacOSX10.4u.sdk rather than changing it to /Developer/SDKs/MacOSX10.5.sdk.
