- Mon Nov 17, 2014 8:48 am #2793 Hi,
I'm trying to setup a complete IDE for esp8266 using Ubuntu VirtualBox, official esp gcc and eclipse.

1. I've downloaded official GCC, followed the instructions and successfouly compliled IOT_Demo from command line.

2. I've downloaded Eclipse and installed it ( together with JRE ) onto my Ubuntu VirtualBox

3. I launched Eclipse, and created the project like File->New->Project->makefile Project with existing code pointing the project source onto /app directory

4. After the projec got created I edited Project->Properties->Builders and added new builder configuration setting:

Location: /home/esp8266/Share/esp_iot_sdk_v0.9.2/app/gen_misc.sh
Working Direstory: /home/esp8266/Share/esp_iot_sdk_v0.9.2/app/

5. I tried to build with Project->Build All and received the following output in console:

6. because of errors I checked if xt-objdump or xt-objcopy are accessible from command line and they are... besides as mentioned at the very beginning from command line ( LXTerminal ) I can compile with ./gen_misc.sh w/o any errors...

what am I doing wrong?
Thanks in advance!

- Tue Mar 03, 2015 2:19 pm #11192 You probably need to create symbolic links that point to /bin folder of open esp sdk.

Probably something like:
ln -s esp-open-sdk/xtensa-lx106-elf/bin/xtensa-lx106-elf-objdump esp-open-sdk/xtensa-lx106-elf/bin/xt-objdump

And than make sure you have esp-open-sdk/xtensa-lx106-elf/bin in your PATH.

- Tue Mar 03, 2015 2:45 pm #11196 don't use the official toolchain or vm its a pile of poo and doesn't work.

use https://github.com/pfalcon/esp-open-sdk

- Thu Apr 30, 2015 1:39 am #16060 Just rename(or make copy) xtensa-lx106-elf-nm into xt-nm!
