Build script for the Xtensa toolchain. (Mingw/linux)
#!/bin/bash
# Author: Fabien Poussin
# Last edit: 20/11/2014
#
# You will need the following mingw32/64 or equivalent linux packages to build it:
# msys gcc msys-coreutils msys-wget msys-autoconf msys-automake msys-mktemp
#
# Use mingw-get to install these.
# run this script from msys's or any unix console.

Hi Fabien

I'm trying to use your script t compile the Xtensa compiler for the esp8266 wifi device

However gcc seems to hang while compiling, usually tmp-divrew_1.s , but sometimes other .s files if I quite and restart

Looking at the Task manager in windows Make.exe is showing 50% cpu all the time and memory of 1024k

Do you have any ideas why this may hang ?

Edit. I've just noticed your script of for linux and not MinGW under windows - which is what I'm trying to use it for,
So I guess this must be a MinGW issue :-(

Edit.

Fixed it.
On Windows MinGW, it hangs if jobs are set to parallel, so I changed to -j1 instead of -j6

-j2 etc may also work, but it may depend on how many cores your machine has

Hey,

Sorry for the late answer, I just saw your message.
The script is for linux and mingw, possibly cygwin. I did test it with mingw32/64 using -j6 and everyting went fine. (On W7 64)
There are some known issues with make.exe on mingw, you might want to try other versions. (try to google it)
