build step for 'chip_gn' failed No such file or directory (CON-1419)

[North3rnL1ght]

Describe the bug
I downloaded and installed ESP-IDF and ESP-Matter for apple/swift-matter-examples. I used the installation tutorial they provided. But for some reason I can't build the example for the smart-light. I even tried the examples provided inside the esp-matter folder but I always recive the following error during Build.

[702/1257] Performing build step for 'chip_gn'
FAILED: esp-idf/chip/chip_gn-prefix/src/chip_gn-stamp/chip_gn-build esp-idf/chip/lib/libCHIP.a /Users/account/esp-matter/examples/light/build/esp-idf/chip/chip_gn-prefix/src/chip_gn-stamp/chip_gn-build /Users/account/esp-matter/examples/light/build/esp-idf/chip/lib/libCHIP.a

Environment

• ESP-Matter Commit Id: 7b9d69a (grafted, HEAD -> release/v1.2, origin/release/v1.2)

• ESP-IDF Commit Id: a322e6bdad4b6675d4597fb2722eea2851ba88cb (grafted, HEAD, tag: v5.2.1)

• SoC (eg: ESP32 or ESP32-C3): ESP32-C6

• Host Machine OS: MacOS 15.1 (24B83)

• Host Machine Python version: 3.9.6

Any additional details
The Problem is that the build.ninja trys to execute the following command:

#############################################
# Custom command for esp-idf/chip/chip_gn-prefix/src/chip_gn-stamp/chip_gn-build

build esp-idf/chip/chip_gn-prefix/src/chip_gn-stamp/chip_gn-build esp-idf/chip/lib/libCHIP.a | ${cmake_ninja_workdir}esp-idf/chip/chip_gn-prefix/src/chip_gn-stamp/chip_gn-build ${cmake_ninja_workdir}esp-idf/chip/lib/libCHIP.a: CUSTOM_COMMAND esp-idf/chip/chip_gn-prefix/src/chip_gn-stamp/chip_gn-configure || esp-idf/chip/args_gn
  COMMAND = cd "/Users/account/esp-matter/connectedhomeip/connectedhomeip/config/esp32/components/chip;/Users/account/esp-matter/examples/light/build/esp-idf/chip" && ninja esp32
  DESC = Performing build step for 'chip_gn'
  restat = 1

Which results in "No such file or directory". When I manually edit the build.ninja file and remove the first PATH "/Users/account/esp-matter/connectedhomeip/connectedhomeip/config/esp32/components/chip;" the build executes successfully. I don't know where it takes the first path from. Even tried reinstalling esp-matter and esp-idf but it didn't made any changes.

I have the same problem here with esp-matter and swift-matter-examples,
and editing the command (replacing ; with " && cd ") resolved it.

Thanks! Let's wait for a fix.

@North3rnL1ght thanks for the detailed debugging, will see how this can be fixed.

On my mac, I am unable to reproduce this. I only see one path in build.ninja, not sure how that extra path added.
I'm using following gn, ninja, cmake, versions, can you please share your's.

$  esp-matter git:(7b9d69a) gn --version
2123 (5d8727f3fbf4)
$  esp-matter git:(7b9d69a) cmake --version
cmake version 3.30.0
$  esp-matter git:(7b9d69a) ninja --version
1.12.1

[North3rnL1ght]

@shubhamdp I found this extra path inside the list of component path output on set-target for esp32c6.

Copied only some until the components/chip folder path occours!

-- Component paths: /Users/account/esp-matter/examples/common/app_bridge /Users/account/esp-matter/examples/common/app_reset /Users/account/esp-idf/components/app_trace /Users/account/esp-idf/components/app_update /Users/account/esp-idf/components/bootloader /Users/account/esp-idf/components/bootloader_support /Users/account/esp-idf/components/bt /Users/account/esp-matter/connectedhomeip/connectedhomeip/config/esp32/components/chip

The only different version is in cmake:

gn --version
2123 (5d8727f3fbf4)
cmake --version
cmake version 3.31.0
CMake suite maintained and supported by Kitware (kitware.com/cmake).
ninja --version
1.12.1

I have the same issue, fixed by rolling back cmake from 3.31.0 to 3.30.5.

[shubhamdp]

@nicolas-christe thanks for the tip. Please check if project-chip/connectedhomeip#36606 can fix the problem with cmake v3.31.x. You can apply the PR by running following command in esp-matter.

[nicolas-christe]

Thanks @shubhamdp, I confirm that the patch works for me with both cmake 3.30.5 and 3.31.0.

[North3rnL1ght]

@shubhamdp thank you very much. Patch works for me as well on cmake 3.31.0 👍
