Build Error: Missing target lib/libapp_zig.a needed by zig-sample-idf.elf during ESP32 build

[MainManu]

I cannot get idf.py to build the sample.

Info

Zig version: 0.13.0
idf.py version: ESP-IDF v5.5-dev-1898-g472792eb8a-dirty
Target: ESP32

Steps to reproduce

1. clone the repo
2. install latest idf.py
3. set target ESP32 (idf.py set-target esp32)
4. build (idf.py build)

Error

make[2]: *** No rule to make target 'lib/libapp_zig.a', needed by 'zig-sample-idf.elf'. Stop. make[1]: *** [CMakeFiles/Makefile2:2564: CMakeFiles/zig-sample-idf.elf.dir/all] Error 2 make: *** [Makefile:136: all] Error 2

Hi @MainManu,

Missing more information... Please, show full-log.
Have you already tried idf v5.4?

It seems that zig was not found to build libapp_zig. This doesn't make sense because cmake will download & run zig-xtensa by default.

I tested idf-master and I didn't get the same problem you presented.

Thanks for the quick reply @kassane . As I am on the move rn, I tried again on a macbook with the exact same zig and IDF version, and for some reason it built without issues. Seems to be related to the gcc or ninja versions. Will post the full logs tomorrow.
