OverviewToolchain 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.
