- Thu Jan 08, 2015 11:28 am #6694 I 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.

Code: Select allESP_HOME=$PWD/Espressif
mkdir -p $ESP_HOME

function install_compiler {
cd $ESP_HOME
git clone -b lx106 git://github.com/jcmvbkbc/crosstool-NG.git
cd crosstool-NG
./bootstrap && ./configure --prefix=`pwd` && make && make install
./ct-ng xtensa-lx106-elf
./ct-ng build
chmod -R u+w $ESP_HOME/crosstool-NG/builds/xtensa-lx106-elf
export PATH=$ESP_HOME/crosstool-NG/builds/xtensa-lx106-elf/bin:$PATH
}

function install_sdk {
cd $ESP_HOME
