Toolchain build script.
Posted: Thu Jan 08, 2015 11:28 amI wrote a build script based on the instructions at:
https://github.com/esp8266/esp8266-wiki/wiki/Toolchain
Instead of just downloading binaries for libc.a and libhal.a I actually build those packages from the sources specified. What I'd really like to do however, is download source releases for tools like crosstool-NG and newlib, and apply patches. Does anyone have any suggestions for that?
Anyway, for what it is worth, here is my script. I'm running it on ubuntu 14.04, so ymmv. Let me know if you have any suggestions for improvement.
