I've successfully generated the toolset on OSX, and set

echo "PATH=$(pwd)/xtensa-lx106-elf/bin:\$PATH" >> ~/.bash_profile

I've done cd micro python/esp8266 but when I try to do make I get the errors below.

make: xtensa-lx106-elf-gcc: Command not found
GEN build/genhdr/qstrdefs.generated.h
/bin/sh: xtensa-lx106-elf-gcc: command not found
ERROR: Empty preprocessor output - check for errors above
make: *** [build/genhdr/qstrdefs.generated.h] Error 1
make: *** Deleting file `build/genhdr/qstrdefs.generated.h'

Help me build this firmware!

Did you restart your shell session to make the bash_profile settings take effect? You can check by doing: echo $PATH.

@dpgeorge Thanks for your response. I sure did. 'echo $PATH' returns /Users/me/Documents/gitStuff/pySerialStuff/micropython/esp8266/xtensa-lx106-elf/bin:/Users/me/Documents/gitStuff/pySerialStuff/micropython/esp8266/xtensa-lx106-elf/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

Then if you type xtensa-lx106-elf-gcc at the command line it should work, does it?

It doesn't :(

anty:~/Documents/gitStuff/pySerialStuff/micropython/esp8266 🚦  xtensa-lx106-elf-gcc

-bash: xtensa-lx106-elf-gcc: command not found

A file search doesn't yield any files by the name xtensa-lx106-elf-gcc should that be somewhere in the esp-open-sdk? Also there's no reference to it in my bash_profile.

ok - fixed this by remaking the toolchain and then doing
export PATH=/Volumes/esp-open-sdk/esp-open-sdk/xtensa-lx106-elf/bin:$PATH

(to anyone looking at this it depends on installing the toolchain in a case-sensitive disk image named eep-open-sdk)

OK. the make command works now but there's another error.
