Lua is a powerful light-weight programming language designed for extending applications. It is also frequently used as a general-purpose, stand-alone language. Lua is implemented as a small library of C functions, written in ANSI C, and compiles unmodified in all known platforms. The implementation goals are simplicity, efficiency, portability, and low embedding cost. The result is a fast language engine with small footprint, making it ideal in embedded systems too.
This package is known to build and work properly using an LFS 12.2 platform.

Install Lua by running the following commands:
patch -Np1 -i ../lua-5.4.7-shared_library-1.patch && make linux
To test the results, issue: make test. “This will run the interpreter and print its version.” More comprehensive tests can be performed if you downloaded the "Test suite" tarball. Those tests need to be executed after the package is installed, thus we defer to the description below.
Now, as the root user:
make INSTALL_TOP=/usr \
INSTALL_DATA="cp -d" \
INSTALL_MAN=/usr/share/man/man1 \
TO_LIB="liblua.so liblua.so.5.4 liblua.so.5.4.7" \
install &&
mkdir -pv /usr/share/doc/lua-5.4.7 &&
cp -v doc/*.{html,css,gif,png} /usr/share/doc/lua-5.4.7 &&
install -v -m644 -D lua.pc /usr/lib/pkgconfig/lua.pc
Here we describe only the "Basic tests". Untar the tarball and
change to the lua-5.4.7-tests
directory, then issue lua -e
"_U=true" all.lua. If the tests finish without
error, you will see a message containing the string "final OK".
