Building readline 5.2 on OS X Leopard

Readline 5.2 does not build properly on OS X Leopard. It fails with a  -compatibility_version only allowed with -dynamiclib error. I ran into this problem when trying to build ruby, using GNU readline instead of the default editline. The problem is easily fixed though. Readline explicitly checks for the darwin version, but does not include 9 (Leopard) in this check. Patch support/shobj-conf using the following:

  3. I’m not sure why, but I got this error:
    /tmp/readline-5.2> patch -p0 < leopard.patch
    patching file support/shobj-conf
    patch: **** malformed patch at line 4: ;;

    I’m no patch(1) wizard, so maybe I missed an incantation. I got around it by just editing the file per the patch, though.

    Very helpful anyway, though. Thanks!

  5. Firstly – thanks for the patch – it enabled me to build readline on OS X 10.5.2.

    But I still can’t build ruby 1.9! Breaks on ‘compiling readline’:

    readline.c: In function ‘filename_completion_proc_call’:
    readline.c:670: error: ‘filename_completion_function’ undeclared (first use in this function)
    readline.c:670: error: (Each undeclared identifier is reported only once
    readline.c:670: error: for each function it appears in.)
    readline.c:670: warning: assignment makes pointer from integer without a cast
    readline.c: In function ‘username_completion_proc_call’:
    readline.c:695: error: ‘username_completion_function’ undeclared (first use in this function)
    readline.c:695: warning: assignment makes pointer from integer without a cast
    make[1]: *** [readline.o] Error 1
    make: *** [all] Error 1

    Surely someone must’ve got past this by now? I’ve done so much googling, but have turned up nothing that works…

  6. @James: Make sure to point to the right readline when building Ruby 1.9, like so:

    ./configure –prefix=/usr/local/ruby1.9 –with-readline-dir=/usr/local

  7. […] June 28, 2008 by rubyopals Problems installing Gnu readline 5.2 on OS X Leopard. Good explanation. […]

  8. Hi,
    first of all, many thanks to Han for the brilliant hints. Although, even after applying all of them, I still received the same problem with Ruby 1.8.7p22 and 1.9.0 (but not with 1.8.6p120). Here is what finally did the job for me (using Leopard):
    1) Download readline 5.2
    2) Download all patches for readline 5.2 (currently 12 patches are available)
    3) apply all patches
    4) ./configure, make and sudo make install for patched readline [no parameters for my installation]
    5) download Ruby 1.8.7 or 1.9.0
    6) run ./configure –with-readline-dir=/usr/local
    7) run make and sudo make install
    I’m not sure where the differences are compared to Han’s recipe (I’m not very experienced experienced on compiler/make level). But it worked…

  9. The latest patch for the current version (at http://ftp.gnu.org/gnu/readline/readline-5.2-patches/readline52-012) is substantially the same as what Han provides above. It patches the OS check for Leopard (and a few other systems).

    So if the one given here doesn’t work, that’s the next step.

  11. Can someone provide more explicit directions on how to apply patch #12?

    I was able to apply the GNU patches 1-11 without any troubles, but with #12, there was an error:

  13. Worked great for me. With regard to Eric’s question: when it says “File to patch: “, just input “support/shobj-conf”. The patch itself fails to look in the support directory.

  16. […] As it happens, when I compiled Python 2.5 or higher on OS X, it linked to either the OS X readline library or the MacPorts one. Which one I don’t know, but it was definitely hosed. So while the interpreter worked fine, the interpreter shell would crash with a Bus Error. So what I did was compile my own plain vanilla version of readline and installed it to /opt. Of course that didn’t work right away because readline wouldn’t build on OS X Leopard without applying a small patch to a build script. […]

  17. […] Taken verbatim from here […]

  18. Issue the following command on Snow Leopard (10.6) after compiling Python (assumed path = /opt/Python-2.6.3) to add readline support to the new Python install.

    cp /System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload/readline.so /opt/Python-2.6.3/lib/python2.6/site-packages/
