It's the first file it tries to build for gcc. Basically the relevant part of the log is:

So the compiled xtensa gcc assembler doesn't have the --32/--64 options, since it's build for the different architecture.

Code: Select all./as --version
GNU assembler (GNU Binutils) 2.24
...
This assembler was configured for a target of `xtensa-lx106-elf'.


Native gcc-as however does have these options and i can run /usr/bin/as --64 no problem. So I think the issue is somewhere in config scripts picking up this parameter from my local configuration. I'll have a look a bit more into it.

- Sat Dec 06, 2014 7:55 pm #4162 @Cnlohr, building the toolchain with crosstool-NG is much simpler: no manual downloads/renames. Described here: https://github.com/esp8266/esp8266-wiki/wiki/Toolchain
Otherwise great video (:

- Sat Dec 06, 2014 7:58 pm #4163 Can't seem to find the issue, all the tools compile just fine, but the assembler refuses to use --64.
Might try using crosstool-ng instead.

I found a bug in the command list that breaks the whole process:

Under "Setting up the Espressif SDK" there's a `mkdir ESP8266_SDK` that should not be there. That causes the contents of the SDK zip to be under two directory levels instead of one. This causes the next patching step to fail as pasted because you're in the wrong directory, and also causes the blinky example to fail to build with a lack of include files in the right places.
