Package Information

Installation of luajit

Install luajit by running the following commands: 

make PREFIX=/usr amalg

This package does not come with a test suite.

Now, as the root user: 

make PREFIX=/usr install &&
rm -v /usr/lib/libluajit-5.1.a

Command Explanations

amalg: This ensures an amalgamated build, i.e. the LuaJIT core is compiled as one huge C file, allowing GCC to generate faster and shorter code.
