[Bug] Compilation error: "error: conflicting declaration of C function"

[abishekgoda]

Describe the bug

I am trying to compile zenoh-pico to run on esp8266 (esp01 board). I am following along the readme file in the project to do this. I am using PlatformIO Core, version 6.1.16 on a m1 mac running macos 15.2. When I try pio run I get a bunch of conflicting declaration errors. It looks like an overloaded function but the compiler is "C" based. Or maybe am interpreting it wrong. How do I proceed?

To reproduce

1. Use the example in the README.md
2. Use the following platformio.ini:

platform = espressif8266
board = esp01
framework = arduino
lib_deps = arduino-libraries/WiFi@^1.2.7
build_flags = -DZENOH_ARDUINO_ESP32 

3. pio run

System info

• Mac OS 15.2 / M1 Mac.
• ESP01 board with 1M memory. Am choosing basic 512K option

Can you try with this platformio.ini:

[env:esp32thing_plus]
platform = espressif8266
board = esp01
framework = arduino
lib_deps = 
	arduino-libraries/WiFi@^1.2.7
	zenoh-pico
build_flags = 
	-DZENOH_COMPILER_GCC
	-DZENOH_ARDUINO_ESP32 

[abishekgoda]

No. Still the same.
err.log has the full set of errors. Thanks!

You're using a non-arduino application/example (based on freertos it seems) with an arduino framework. Please retry with an app/example from the arduino folder.

For this kind of issues you should contact us on the z_support on our discord.

That is odd. I am following the README verbatim. And I don't even know what freertos is :-( . I'll check with the discord.

Sadly, it's highly probable there's missing / obsolete info in the doc, we're working on improving it.
