Lua-5.2.4

Introduction to Lua 5.2

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 is an older verion of Lua needed only for compatibility with other programs such as Wireshark-3.0.6.

This package is known to build and work properly using an LFS-9.0 platform.

Installation of Lua 5.2

Some packages check for the pkg-config file for Lua, which is created with:

cat > lua.pc << "EOF"
V=5.2
R=5.2.4

prefix=/usr
INSTALL_BIN=${prefix}/bin
INSTALL_INC=${prefix}/include/lua5.2
INSTALL_LIB=${prefix}/lib
INSTALL_MAN=${prefix}/share/man/man1
INSTALL_LMOD=${prefix}/share/lua/${V}
INSTALL_CMOD=${prefix}/lib/lua/${V}
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include/lua5.2

Name: Lua
Description: An Extensible Extension Language
Version: ${R}
Requires:
Libs: -L${libdir} -llua -lm -ldl
Cflags: -I${includedir}
EOF

Install Lua by running the following commands:

patch -Np1 -i ../lua-5.2.4-shared_library-1.patch &&

sed -i '/#define LUA_ROOT/s:/usr/local/:/usr/:' src/luaconf.h &&

sed -r -e '/^LUA_(SO|A|T)=/ s/lua/lua5.2/' \
       -e '/^LUAC_T=/ s/luac/luac5.2/'     \
       -i src/Makefile &&

make MYCFLAGS="-fPIC" linux

The installation of this package is complex, so we will use the DESTDIR method of installation:

make TO_BIN='lua5.2 luac5.2'                     \
     TO_LIB="liblua5.2.so liblua5.2.so.5.2 liblua5.2.so.5.2.4" \
     INSTALL_DATA="cp -d"                        \
     INSTALL_TOP=$PWD/install/usr                \
     INSTALL_INC=$PWD/install/usr/include/lua5.2 \
     INSTALL_MAN=$PWD/install/usr/share/man/man1 \
     install &&

install -Dm644 lua.pc install/usr/lib/pkgconfig/lua52.pc &&

mkdir -pv install/usr/share/doc/lua-5.2.4 &&
cp -v doc/*.{html,css,gif,png} install/usr/share/doc/lua-5.2.4 &&

ln -s liblua5.2.so install/usr/lib/liblua.so.5.2   &&
ln -s liblua5.2.so install/usr/lib/liblua.so.5.2.4 &&

mv install/usr/share/man/man1/{lua.1,lua52.1} &&
mv install/usr/share/man/man1/{luac.1,luac52.1}

Now, as the root user:

chown -R root:root install  &&
cp -a install/* /

Command Explanations

sed -i ... src/luaconf.h: This command changes the Lua search path to match the install path.

sed -i ... src/Makefile: This command deconflicts this installation with the latest version of lua.
