Lua-5.2.3

Introduction to Lua

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-7.5 platform.

Installation of Lua

Install Lua by running the following commands:

patch -Np1 -i ../lua-5.2.3-shared_library-1.patch &&
sed -i '/#define LUA_ROOT/s:/usr/local/:/usr/:' src/luaconf.h &&
make linux

To test the results, issue: make test.

Now, as the root user:

make INSTALL_TOP=/usr TO_LIB="liblua.so liblua.so.5.2 liblua.so.5.2.3" \
     INSTALL_DATA="cp -d" INSTALL_MAN=/usr/share/man/man1 install &&
mkdir -pv /usr/share/doc/lua-5.2.3 &&
cp -v doc/*.{html,css,gif,png} /usr/share/doc/lua-5.2.3

Some packages check for the pkg-config file for Lua. As the root user:

cat > /usr/lib/pkgconfig/lua.pc << "EOF"
