building on linux fails with error

[zelea2]

I have the latest esp-idf and tools configured just fine. $ idf.py --version ESP-IDF v5.2-dev-1128-g03d4fa2869-dirty I can compile all the examples in the esp-idf directories with the $ idf.py build` command.

$ git branch * master-v4.3 $ git pull Already up to date.

When I try to build or configure squeezelite-esp32 I first get a complaint about missing the nghttp component so then I do $ idf.py add-dependency nghttp Created "/home/xxx/squeezelite-esp32/main/idf_component.yml" Successfully added dependency "espressif/nghttp*" to component "main"

If then I try to build or configure the firmware I get this error and I don't know how to solve this: -- Building ESP-IDF components for target esp32 Processing 2 dependencies: [1/2] espressif/nghttp (1.52.0) [2/2] idf (5.2.0) CMake Error at /opt/esp/esp-idf/tools/cmake/build.cmake:268 (message): Failed to resolve component 'esp32'.

have a look at the readme. There we provide some steps for building the system, with docker being the most successful path to success. You are using an unsupported version of the ESP-IDF and this will not work given all the dependencies that are tied to the version of the idf we use for this project. We try to keep up to date, but version 5.2 is too much on the bleeding edge for us to consider at this point and wouldn't bring much value while causing lots of headaches for retrofitting (the error provided being just the tip of the iceberg).

You can have a look at the docker image definition if you want to replicate the build environment on a linux computer. it contains all the steps to successfully setup the dependencies, including the very specific commit of the esp-idf that we use.

I've tried to build the firmware via docker but still no success

First I had to change permissions on 2 files:

# chmod 755 /workspace/squeezelite-esp32/squeezelite-esp32/build/esp-idf/spotify/cspot/nanopb/generator/protoc-gen-nanopb # chmod 755 /workspace/squeezelite-esp32/squeezelite-esp32/build/esp-idf/spotify/cspot/nanopb/generator/nanopb_generator.py

then

# ./buildFirmware.sh [...] `../components/_override/esp32/i2s.c:41:10: fatal error: soc/chip_revision.h: No such file or directory

include "soc/chip_revision.h"`

also ninja: error: unknown target 'size-components-squeezelite' command "size-components-squeezelite" is not known to idf.py and is not a Ninja target

Which docker image did you use? Having a look at our platform build config is the best way to build right now.: https://github.com/sle118/squeezelite-esp32/blob/master-v4.3/.github/workflows/Platform_build.yml#L21

and we are currently using this docker image: sle118/squeezelite-esp32-idfv435

hope this helps. Out of curiosity, why build locally when there are already binaries available for pretty much all platforms (hard coded or via nvs config)?

I'll try again on Monday following your instructions. The reason I'm trying to build this is that I'm about to design a PCB (which is supposed to be easy to solder) based on ESP32-TTGO-V1.8, ES9023 and a W5500-Module. Schematic is attached and I've already configured the sdkconfig accordingly. Squeeze-ESP32.pdf

Looking forward to seeing your progress with designing your board. Note that you do not have to build a custom binary, as @philippe44 and myself have been working hard to make sure everything was software configurable including any init sequence that has to be sent to the DAC.

I've managed to compile it via docker and idfv435 instead of idfv43 (maybe you should change the README as well). I know that I can configure it via NVS but it's more convenient to have it already configured at build time.

Done with this https://github.com/sle118/squeezelite-esp32/commit/b38354420c16902f0d08cde275a91d27082f5e27. Closing this for now.
