error when I try to build pacman clockface

[makerawei]

I put PNGdec in clockwise\components and add a CMakeLists.txt file as below

cmake_minimum_required(VERSION 3.15)

if(ESP_PLATFORM)
	# Build ArduinoJson as an ESP-IDF component
	idf_component_register(INCLUDE_DIRS src)
	return()
endif()

project(PNGdec VERSION 1.0.1)
add_subdirectory(src)

[jnthas]

Got it. Let me ask @abrender maybe he knows the issue.

[makerawei]

@abrender could you please help me to solve the error；）thanks a lot !

[jnthas]

@makerawei take a look at this branch, i was able to build it without errors -> #70

I dont know you are aware but you don't need to use esp-idf to compile the project, just open it in platform.io and it will work fine with arduino framework

[makerawei]

@jnthas thanks a lot；）
I tested your commit, and for success building there should be a CMakeList.txt in PNGdec

if(ESP_PLATFORM)
	idf_component_register(INCLUDE_DIRS src)
	return()
endif()

project(PNGdec VERSION 1.0.1)
add_subdirectory(src)

And a code line in cw-cf-0x07/Clockface.cpp:198 is always true.

bool shouldReturnToOrigin = doc["loop"][sprite->_spriteReference]["shouldReturnToOrigin"].as<bool>() ? : false;

this code would be error in my ESP-IDF env.
After change it to

bool shouldReturnToOrigin = doc["loop"][sprite->_spriteReference]["shouldReturnToOrigin"].as<bool>() ? true : false;

I build pacman success !

[jnthas]

Great! As PNGdec don't have the CMakesList file, you could open a PR there if you want.
