Cannot build the hello world sample

[timothyp]

Hi,

First off, Github is now as good as blocked in Shenzhen, and when it does work the connection gets cut ever few minutes,
so I spent more than 4 days to download esp-idf and then run `./install.sh` which just downloads more stuff.
As a Chinese company, you should probably provide local mirrors for everything.

Then today everything finally downloaded, I entered the `esp-idf/examples/get-started/hello_world` directory
and ran:

Code: Select all

idf.py build

This once again triggered a bunch of downloads from Github that took 4 hours to complete and resulted in

Code: Select all

 idf.py build
Executing action: all (aliases: build)

Any suggestions?

Hello timothyp.

I think you still don't have everything downloaded. Please go to the IDF directory and run

Code: Select all

git submodule update --init --recursive

.

[timothyp]

You are correct.
Apparently it is downloading more stuff again.
This could take anything from minutes to a few days.
Will try again after that.

Is there a local mirror (or single package download) anywhere.
The blockade is affecting a lot of people.

[ESP_Roland]

Unfortunately, there is no Chinese mirror at the time.

The releases page (https://github.com/espressif/esp-idf/releases) contains also links to ZIP files from dl.espressif.com which should be much faster for you:

Code: Select all

This archive can also be downloaded from Espressif's download server:
https://dl.espressif.com/dl/esp-idf/releases/esp-idf-v4.0.zip

These ZIP files contain also the .git directory so normal GIT command should work on the downloaded repository.

[timothyp]

I downloaded that one before as well but it still tried to download stuff.

Now if this completes. I will have data in ~/Downloads/esp-idf/ and ~/.espressif
Do I need to copy them both if I move to a different system or can I just copy the esp-idf folder?

[ESP_Roland]

The install script downloads the toolchain as well (binutils, openocd, xtensa). You can copy files from ~/.espressif/dist between computers and then the install script will recreate the other directories and files in ~/.espressif without downloading. I don't recomment to copy the whole ~/.espressif directory.

You can copy the whole esp-idf directory.

hello,
how about the error? does it solved?
