Building toolchains

Toolchain building tutorials

Although not strictly required, you can roll your own toolchain that can be used to build eLua. As explained here, eLua can generally be built with ready-made toolchains (with the exception of the i386 port), but you might still want to build your own toolchain for various reasons:

• have a better control over the compilation options of different libraries (most notably libc).
• use a specific version of gcc/newlib.
• your toolchain might generate smaller code than a pre-built toolchain.
• get familiar with the binutils/gcc/newlib build system (not related to eLua, but still a good reason).

Three separate tutorials explain the procedure of building a regular ARM toolchain, a Cortex-M3 toolchain and an i386 toolchain, respectively.
