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 12.4 platform.

Name: Lua
Description: An Extensible Extension Language
Version: ${R}
Requires:
Libs: -L${libdir} -llua -lm -ldl
Cflags: -I${includedir}
EOFPrepare Lua by running the following commands:
patch -Np1 -i ../lua-5.4.8-shared_library-1.patch
To Build the package, issue:
make linux
“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. To test the results, issue:
make test
Now Install the package, 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.5.4.8" \
install
mkdir -pv /usr/share/doc/lua-5.4.8
cp -v doc/*.{html,css,gif,png} /usr/share/doc/lua-5.4.8
install -v -m644 -D lua.pc /usr/lib/pkgconfig/lua.pcIf the tests finish without error, you will see a message containing the string "final OK". Extract the downloaded tarball and change to the directory, by running the following commands:
tar -xf ../lua-5.4.8-tests.tar.gz cd lua-5.4.8-tests lua -e "_U=true" all.lua
