User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/slang

Installation of S-Lang

Install S-Lang by running the following commands: 

./configure --prefix=/usr --sysconfdir=/etc &&
make

To test the results, issue: make check. Note that this will also create a static version of the library which will then be installed in the next step.

Now, as the root user: 

make install_doc_dir=/usr/share/doc/slang-2.2.4   \
     SLSH_DOC_DIR=/usr/share/doc/slang-2.2.4/slsh \
     install-all &&

chmod -v 755 /usr/lib/libslang.so.2.2.4 \
             /usr/lib/slang/v2/modules/*.so

Command Explanations

make install_doc_dir=/usr/share/doc/slang-2.2.4 SLSH_DOC_DIR=/usr/share/doc/slang-2.2.4/slsh install-all: This command installs the static library as well as the dynamic shared version and related modules. It also changes the documentation installation directories to a versioned directory.

--with-readline=gnu: Use this parameter to use the Gnu Readline parser instead of the S-Lang internal version.
