Ruby 1.8.7, Snow Leopard, readline and openssl

Had a lot of trouble getting Ruby 1.8.7 (p160), readline and openssl to combine to let ruby compile on Snow Leopard.

Solution:

readline-6.0
./configure –prefix=/opt/ruby187rubygems135
make
sudo make install

For ruby:

./configure –prefix=/opt/ruby187rubygems135 –disable-pthread –enable-shared –with-readline-dir=/opt/ruby187rubygems135
make
sudo make install

Note that specifying something like ‘-with-openssl=/usr’ breaks the compile. Leaving the SSL option off works.

What readline installs

A clean install of readline yields the following files in relative to the installation base:

/include

/include/readline

chardefs.h
history.h
keymaps.h
readline.h
rlconf.h
rlstdc.h
rltypedefs.h
tilde.h

/lib

libhistory.5.2.dylib
libhistory.5.dylib
libhistory.a
libhistory.dylib
libreadline.5.2.dylib
libreadline.5.dylib
libreadline.a
libreadline.dylib

readline and ruby – When bad things happen

With great thanks to Gravitas for saving hours of fruitless labors.

Symptom:

All ruby command-line tools – irb, console – fail to respond to terminal keys  – e.g. cursor keys

Solution:

readline

make clean
./configure CPPFLAGS=-DNEED_EXTERN_PC SHOBJ_LDFLAGS=-dynamiclib
make CPPFLAGS=-DNEED_EXTERN_PC SHOBJ_LDFLAGS=-dynamiclib
sudo make install

ruby

make clean
./configure --prefix=/usr/local --disable-pthread --with-readline-dir=/usr/local --enable-shared
make
sudo make install

OS X Leopard – readline compile errors

Taken verbatim from 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:
