- Sun Oct 05, 2014 8:41 am #1232 @reaper7 Yeah the tutorial is missing one step described by @mamalala which is to copy the libc and libhal from the original VM's.
You can find further instructions and a link to download these files in his post on page 3.

- Sun Oct 05, 2014 8:44 am #1233 You need to download the libs that mamalala provided in previous post http://www.esp8266.com/viewtopic.php?f=9&t=224&start=40.
The download link is http://atelier-klippel.de/xtensa_libs.tgz, you should place them into your SDK folder.

I have the issue when compiling dumbcraft's "dumbutils.c" from https://github.com/cnlohr/dumbcraft8266
This is using your latest crosstoll-NG from github.
Hope it helps!

Thanks. Confirmed assembler issue. Will fix.

Turns out to be a feature: assembler implicitly creates .literal_position at every entry instruction. I've added explicit .literal_position emitting in gcc for call0 ABI.
gcc and crosstool repos are updated with the fix; now gcc should be able to build code with -mtext-section-literals.

I confirm it is now working!

Thanks a lot!

(prepared for ubuntu 12.04 64-bit from this tutorial: https://nurdspace.nl/ESP8266/First_setup)

If it works for you, my problems seem not to be 64-bit related as I assumed up to now...
I tried to build the toolchain on Debian-64bit-Squeeze-LTE, -Wheezy and -Jessie running into the same problem when trying to build the example:

Code: Select all(yeti@darkstar:8)~/wrk/esp_sources/at$ LANG=C make
CC user/at_ipCmd.c
In file included from /usr/include/stdlib.h:320:0,
                 from user/at_ipCmd.c:9:

 typedef signed long         int32_t;
                             ^
make: *** [build/user/at_ipCmd.o] Error 1

(I do not have ESP8266s yet... I bet they will take weeks to make their way from dot-HK to dot-DE but I want to get the toolchain running before they arrive...)
