The Readline package is a set of libraries that offers command-line editing and history capabilities.
Reinstalling Readline will cause the old libraries to be moved to <libraryname>.old. While this is normally not a problem, in some cases it can trigger a linking bug in ldconfig. This can be avoided by issuing the following two seds:
sed -i '/MV.*old/d' Makefile.in
sed -i '/{OLDSUFF}/c:' support/shlib-install
Apply a patch to fix a known bug that has been fixed upstream:
patch -Np1 -i ../readline-6.2-fixes-2.patch
Prepare Readline for compilation:
./configure --prefix=/usr
Compile the package:
make SHLIB_LIBS=-lncurses
The meaning of the make option:
SHLIB_LIBS=-lncurses
This option forces Readline to link against the libncurses (really, libncursesw) library.
This package does not come with a test suite.
Install the package:
make install
Now move the dynamic libraries to a more appropriate location and fix up some symbolic links:
mv -v /usr/lib/lib{readline,history}.so.* /lib
ln -sfv ../../lib/$(readlink /usr/lib/libreadline.so) /usr/lib/libreadline.so
ln -sfv ../../lib/$(readlink /usr/lib/libhistory.so ) /usr/lib/libhistory.so
If desired, install the documentation:
mkdir -v /usr/share/doc/readline-6.2
install -v -m644 doc/*.{ps,pdf,html,dvi} \
/usr/share/doc/readline-6.2
