install readline 5.1

Question

install readline 5.1

Hi,

I am following this article on how to install ruby and gems :
http://hivelogic.com/articles/2005/12/01/rubyrails_lighttpd_mysqltiger

I know that there will be problems later on with Xcode other than version 2.0 (ruby.h will be located elsewhere due to universal binaries) so I use Xcode 2.0 (from my Tiger DVD)

I try to install readline 5.1 on my system (after a clean install) and all I get is
this:

/bin/sh ../support/mkdirs /usr/local/lib
/bin/sh ../support/shlib-install -O darwin8.5.0 -d /usr/local/lib -b /usr/local/bin -i "/usr/bin/install -c -m 644" libhistory.5.1.dylib
/bin/sh ../support/shlib-install -O darwin8.5.0 -d /usr/local/lib -b /usr/local/bin -i "/usr/bin/install -c -m 644" libreadline.5.1.dylib
install: you may need to run ldconfig

As far as I know MAC OS X does not need ldconfig.....but I am not sure

No matter what I do,readline will not install....

I have not found anything of use to resolve this issue.....

You are right in that Mac OS X does not "need" ldconfig; the message at the end is just a hint for people to remember using ldconfig on systems that do need it.

What you show looks ok to me -- what makes you think that it wasn't installed successfully? Are the two .dylibs not copied to /usr/local/lib?

Thanks

They are copied to the given location;

I have not gotten a "installed successful" message,that's why I thought it was not installed....

I will continue to install and see what will happen....

Or can you tell me how to check if readline works???

I can't remember whether readline comes with any test program, but I would just assume that everything is fine - after all, the libraries compiled and ended up in the correct place.

You might want to check whether the include files "made it" too; if the libraries are in /usr/local/lib I would expect them in /usr/local/include.

have not found the libraries in usr/local/include.
There is a empty folder /readline. Nothing more.

Ok, I'll just tell you what I did to install readline on my box: I installed Fink from http://fink.sourceforge.net which includes readline along with a large set of other common Unix/Linux packages.

The advantage is: If any package requires some small patch to make it compile/install/run on Mac OS X, the Fink version already includes it.

yeah I know Fink and DarwinPorts.
I don't like them cause most of the packages are not
the latest version.

I will see if it works or not......

Thanks for your help.

as I presumed readline is not working

I get
/usr/local/lib/ruby/1.8/irb/completion.rb:10:in `require': no such file to load -- readline (LoadError)

and now I find the following libs in my /usr/local/lib

libhistory.5.1.dylib.old*
libreadline.5.1.dylib.old*

Ok, I just downloaded the readline-5.1 sources and then did a

./configure --prefix=/usr/local
make
sudo make install

which produced a few errors regarding the documentation, but the library and the include files ended up where expected, and the included examples work too, even when manually linked against the dynamic libraries in /usr/local/lib.

The .old libraries look as if they are the remains of a later, failed installation process; what happens when you remove the .old suffix?

The error message now looks as if it came from something Ruby related, not from readline itself; which would be likely if the original readline installation failed.

I am using Apple gcc 5247 on 10.4.5, and just to be sure I compiled readline again, this time without all the Fink-installed software in my $PATH, and it seemed to work too. (Just to be extra sure I compiled gnuplot 4.0 against it and again it works).

Now the question is, does your setup differ from mine in any way that breaks readline, or is Ruby not picking up readline correctly? Perhaps you could try to install readline again just with the three commands above, ignoring all errors? Did you check where Ruby even looks for readline?

Sorry I can't help more other than to say that it works here; and of course it could be anything different on your system that happens to break "something".

My installation is identical.

Yes, the error message is ruby related;
Ruby's IRB is supposed to use readline (tab completion feature)
Ruby was compiled with this feature;
( ./configure --prefix=/usr/local --enable-pthread --with-readline-dir=/usr/local )
readline was installed before the installation of Ruby

No there was no failed installation;I did the install on a clean install of Tiger.

Due to a problem with the relocation of some header-files (universal binaries) in Xcode >2.0 I have not installed the latest X-Code Version.
Even though I know how to resolve this issue I chose to stick with X-Code 2.0.

thanks for your help
