Problem building esp-sdk

[slzatz]

Have built it a number of times without problem on Ubuntu but now seeing:

Code: Select all

[INFO ]  Retrieving needed toolchain components' tarballs
[ERROR]   
[ERROR]  >>
[ERROR]  >>  Build failed in step 'Retrieving needed toolchain components' tarballs'
[ERROR]  >>        called in step '(top-level)'
[ERROR]  >>

[ERROR]  >>        called from: main[scripts/crosstool-NG.sh@583]

Anyone else seeing this?

download the tar files manually, i had to do this today

I'm seeing a different problem: it falls over at the last hurdle. I've succeeded previously and the Debian 8.2 VM in use is unchanged:

Code: Select all

same problem, i tried compiling micropython anyways since it looks like whatever its doing there at the end is a patch and not a major componenet... then again i can't get my micropython to compile, keeps complaining that a bunch of files are missing

[pythoncoder]

I'm seeing similar but assumed it was because the toolchain compilation had failed. FWIW I can build the Pyboard firmware without issue so the problem is ESP8266-specific (and presumably toolchain related).

download the tar files manually

Am not exactly an expert -- where are the tar files, what local directory should they go in, and does the Makefile need to be changed?

[pythoncoder]

I've now managed to build the toolchain. This is what I did. I thought I did the same thing this morning but I may have had finger trouble. Otherwise something changed in the interim - git pull did retrieve something. Prior to compiling, in the esp-open-sdk directory, I issued (in accordance with the esp-open-sdk/README.md)

Code: Select all

make clean
git pull
git submodule sync
git submodule update --init

I then issued:

Code: Select all

make

This worked, issuing "Espressif ESP8266 SDK is installed, its libraries and headers are merged with the toolchain". I could subsequently build the firmware with (in micropython):

Code: Select all

git pull origin master
git submodule update --init

Then in esp8266:

Code: Select all

make clean
make axtls
make
