Compilation on windows?

[tocklime]

Is windows compilation supposed to work?

I've cloned the repo, done the git submodules, installed StrawberryPerl and esp-idf-tools with chocolatey.

When I run idf.py build from the checkout in the ESP-IDF terminal I get some output that ends with:

-- Configuring incomplete, errors occurred!
See also "C:/Users/greg/Documents/GitHub/snapclient/build/CMakeFiles/CMakeOutput.log".
cmake failed with exit code 1

I've attached the CMakeOutput.log, but I can't see any obvious things going wrong.

...nope, not windows specific. I get a very similar error in windows subsystem for linux running ubuntu 20.04 and native manjaro.

ah, i got past configuration (and into build errors) by setting ADF_PATH to my checkout of esp-adf.

What specific build errors are you seeing? I have an issue in my checked out code with the opus submodule... Specifically it fails to compile due to a compiler error about an un-initialized variable.

The following diff of the file `components/opus/opus/silk/quant_LTP_gains.c resolves the issue (by initializing the res_nrg_Q15 variable):

yes, i can across that, and fixed it in the same way you got to. I think it compiled after that, but didn't run on my board well (I was using a WROOM not a WROVER). I tried disabling the PSRAM, and I think that got one step further, but I think I stopped around then. I'd like to get it working with a generic ESP32 (if it has to be wrover, then that's ok), and a basic I2S interface. I've got a lyrat mini on order, to play with that too, but I've got esp32s and I2S sound boards lying around now...

Hi Tocklime
Non PSRAM works with limitations to meet snapcast min buffer size (400ms).
ESP32-S0 is untested land - but should be added if it comes with PSRAM.
