Description

Mike 2007-11-15:

Getting tclreadline (2.1.0) running on Mac OSX is a hassle. After running "./configure --enable-tclshrl" followed by "make", i got errors about "Undefined symbols ...". To fix it you need to do the following:

After you have made sure you have a recent version of the readline library (I use 5.2), you will need to make sure that the symbolic link under /usr/lib/libreadline.dylib is pointing to the right location (originally it was pointing to /usr/lib/libedit.dylib).

If you enable tclreadline in your tclsh and get an "alloc: invalid block: ..." error, then you will have to do the following:

Edit tclreadline.c file and rename all MALLOC to malloc and FREE to free (and remove the macros MALLOC and FREE)

Apparently /usr/lib/libedit.dylib is or contains libreadline as a 'nm -o /usr/lib/libedit.dylib' will show you...
I still cannot build tclreadline on Mac OSX. Could someone provide a link to some nice build so that I could RTFM ???
Build on GNU/linux was a breeze...

I just managed to build tcllibreadline on Mac OS 10.4. I first did everything Mike did (note that you will need to have the proper libreadline - I had 5.2 under /usr/local/lib already but I don't think that came with the OS - and check the /usr/lib/libreadline.dylib symlink isn't incorrect). In addition I had to:

set the environment variable MACOSX_DEPLOYMENT_TARGET to 10.4 (I used "setenv MACOSX_DEPLOYMENT_TARGET 10.4" but I use tcsh - always forget the bash syntax).
link glibtool into the build directory with "ln -s /usr/bin/glibtool libtool" as the configure scripts weren't able to create their own.

Things I did to install libtclreadline-2.1.0 and readline-6.1 on Mac OS X 10.6.2 with TCL 8.5 that came with OSX.

built a libreadline.dylib by downloading readline-6.1.tar.gz from http://tiswww.case.edu/php/chet/readline/rltop.html , and following the README. (It's standard procedure: from Terminal, navigate into the readline-6.1 directory, enter './configure', and 'make'.) DON'T 'make install', however.
/usr/lib/libreadline.dylib is a symlink to /usr/lib/libedit.dylib. On the recommendation of someone at the Apple Discussions Unix forum, I renamed the symlink to /usr/lib/libreadline_OLD.dylib and moved my newly-built libreadline.dylib (from previous step) into /usr/lib/. Needed sudo, of course.
built a libtclreadline.dylib by downloading it from http://tclreadline.sourceforge.net/ . (Migraine sufferers are cautioned about the page's color scheme.) Unfortunately, this package is so old it needs some tweaks to get it to build a dylib:

From etresoft on Apple Discussions forum:

... the tclreadline library uses old versions of autoconf. Before calling "./configure" on this project, run "autoreconf -fvi". That will enable shared libraries.

Quite correct - and there's one more thing to do before building.

If you enable tclreadline in your tclsh and get an "alloc: invalid block: ..." error, then you will have to do the following: Edit tclreadline.c file and rename all MALLOC to malloc and FREE to free (and remove the macros MALLOC and FREE)

Having done that, I then ran './configure', 'make', and 'sudo make install'

-- From tclreadline.sourceforge.net:

If you want to use tclreadline as a line interface for developing tcl scripts, you probably don't have to read much of the following section. Just install the package and put the following lines to your $HOME/.tclshrc:

if {$tcl_interactive} {
    package require tclreadline 
    ::tclreadline::Loop
}

My goal was simply to be able to run 'tclsh -i' and have a modern command line for learning and experimenting with TCL. So I did exactly what's described above.

-- It worked. I hope this helps somebody.

These steps are a modified version of Chap's instructions so that you do not have to replace the system libreadline. Tested on MacOS X 10.6.3

Download these two tarballs:

Run these commands:

cd ~/

tar xvzf ~/Downloads/readline-6.1.tar.gz

tar xvzf ~/Downloads/tclreadline-2.1.0.tar.gz

cd ~/readline-6.1/

./configure --disable-shared --prefix=/tmp/readline-install/

make

make install

cd ~/tclreadline-2.1.0/

autoreconf -fvi

./configure --with-readline-includes=/tmp/readline-install/include/readline --with-readline-library=/tmp/readline-install/lib/libreadline.a

egrep -v '#define (FREE|MALLOC)' tclreadline.c | sed 's/MALLOC/malloc/; s/FREE/free/' > tclreadline.c.new

mv -f tclreadline.c.new tclreadline.c

make

sudo make install

rm -rf /tmp/readline-install

hv: Thank you. I followed bovine's instruction and finally got tclreadline to build, installed, and was able to use it. Great instruction.

Debian/Ubuntu offer tclreadline as standard packages, installable via the package manager. After installing tclreadline, a new file .tclshrc must be created in the home directory with following content (same as above):

if {$tcl_interactive} {
    package require tclreadline
    ::tclreadline::Loop
}
