examples/espidf-arduino-blink build fails: unknown type name '_lock_t'

[skiphansen]

I followed the directions in platform-espressif32/examples/espidf-arduino-blink/README.md exactly, but the build failed with error: unknown type name '_lock_t' in lots of places.

Instead of using the zip file I also tired cloning https://github.com/platformio/platform-espressif32.git directly but the example failed the same way in both the master and develop branches.

The examples/arduino-blink builds fine.

I'm new to platformio and I'm trying to build a project that uses classic bluetooth which appears to need a tweak using menuconfig to build. Researching that issue lead me to the espidf-arduino-blink.

Here's my build.log.

I looks like the wrong lock.h is getting included. I've build quite a few projects since I first installed platform IO a week or so ago for several different boards.

I just created a temporary user and installed platformio from scratch and then tried the example and it built without a problem.

Earlier I thought I had caught platformio using the main repo of a library when platformio.ini has specified a particular branch, but I didn't chase that down.

There's still an issue somewhere, but it isn't specific to this example.

Sounds simliar to https://github.com/platformio/platform-espressif32/issues/646#issuecomment-948358453, does the same workaround work?

[skiphansen]

I don't know. When I discovered that a virgin install didn't have the issue I wiped my .platformio/packages directory and that fixed it. I think there's still an issue with a builds not using the correct headers. I don't know enough about platformio to chase it further.

I builded a actual framework. Arduino Core v2.0.2 and IDF v4.4. All included examples in this builded framework do work

platform = https://github.com/tasmota/platform-espressif32/releases/download/v2.0.2idf/platform-espressif32-2.0.2.zip

@skiphansen Did you find a solution? I have the same problem.

[maxgerhardt]

He already said

Same as this person.

@Jason2866 I tried your build to be able to use the arduino,espidf sample (https://github.com/tasmota/platform-espressif32/tree/Arduino2022/IDF44/examples/espidf-arduino-wifiscan) , and I have an error about the crt_bundle file not found...

platform = https://github.com/Jason2866/platform-espressif32/releases/download/v2.0.2/platform-espressif32-2.0.2.zip

Generating assembly for certificate bundle...
CMake Error at C:/Users/xyz/.platformio/packages/framework-espidf/tools/cmake/scripts/data_file_embed_asm.cmake:26 (file):
  file failed to open for reading (No such file or directory):

    D:\project\.pio\build\esp32dev\x509_crt_bundle

It's look like a problem with python3 be more strict on validating the certificate bundles.

followed the instruction here https://github.com/espressif/esp-idf/issues/7631#issuecomment-934212224, delete the sdkconfig.esp32 and now the build is passing.
