I'm am a very beginner at this area and I have a problem compiling an example from ESP8266_NONOS_SDK-master.
I've been following steps described in ESP8266 SDK Getting Started Guide form the documentation.
That means that I downloaded virtual box esp8266 image (ESP8266_lubuntu_20141021.ova) where all tools as I understood must be set up. But while compiling the example I am getting:

/bin/sh: 2: xtensa-lx106-elf-gcc: not found

error.

echo $PATH returns: /opt/xtensa-lx106-elf/bin:/usr/local/sbin:/usr/local/bin:/us‌​r/sbin:/usr/bin:/sbi‌​n:/bin:/usr/games:/u‌​sr/local/games:/snap‌​/bin

and xtensa-lx106-elf-gcc -v returns Configured with ...gcc version 4.8.2 (crosstool-NG 1.20.0)

The compilation happens under esp8266/Share folder.

Can someone tell me what am I missing and how to get SDK to 'see' xtensa-lx106-elf-gcc?

  • @mpromonet echo $PATH returns: `/opt/xtensa-lx106-elf/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin` so it's already there. also `xtensa-lx106-elf-gcc -v` returns `Configured with ...gcc version 4.8.2 (crosstool-NG 1.20.0) ` – snowerest Jun 06 '17 at 20:41
  • it could be nice to add this information to your post, otherwise it seems the PATH have not be set. – mpromonet Jun 06 '17 at 21:17
  • @mpromonet Done. Thank you. – snowerest Jun 06 '17 at 21:27

Xtensa crosstool-NG was missing. To install it used this method. (Do not forget to chown $username /opt/espressif/ in order to avoid 'Permission denied' error while compilation. Also to upgrade OS (if this is chosen) and build crosstool-NG in /opt/espressif, enlarge VM disc size, as it might run out of free space.)
