Build path issue

[Switchleg1]

Analysis

When trying to compile the example vscode(platformio) is unable to find lv_conf.h. Correct valid path is D:/JC3248W535EN-main/src/lv_conf.h and yet the compile exits with error "libraries/lvgl/src/misc/../lv_conf_internal.h:35:42: fatal error: D:JC3248W535EN-main/src/lv_conf.h: No such file or directory"

Expected Behavior

I was hoping it would have compiled :)

Steps To Reproduce

Open project folder with vscode and click build.

Configuration

New to vscode and platformio so please let me know what you would like me to include though I didn't make any changes to the original files that i am aware of.

Environment

• Software: vscode (platformio)
• Node:

This complier directive specifies where to find the file -

JC3248W535EN/platformio.ini

Line 43 in fdf1f3a

-D LV_CONF_PATH=${PROJECT_DIR}/src/lv_conf.h

As your on windows, the pathing may need to be different.

If you are on Windows, try changing:
[JC3248W535EN/platformio.ini](

JC3248W535EN/platformio.ini

Line 43 in fdf1f3a

-D LV_CONF_PATH=${PROJECT_DIR}/src/lv_conf.h

)

Line 43 in [fdf1f3a](fdf1f3a

To: (The quotes help in Windows)
-D LV_CONF_PATH="${PROJECT_DIR}/src/lv_conf.h"

I will give that a go later today though I was pretty sure the issue was the missing slash after 'D:' so I entered the correct location on that line (without quotations) and I received additional errors

Adding quotes resolved the issue, thank you.

An alternative is to define LV_CONF_INCLUDE_SIMPLE in build_flags and omit the LV_CONF_PATH.
This worked under windows without needing to mess with quotes around paths etc.

platformio.ini:

build_flags = 
	${com.build_flags}
	-D LV_CONF_INCLUDE_SIMPLE
	-D LV_USE_DEMO_WIDGETS
; -D LV_CONF_PATH=${PROJECT_DIR}/src/lv_conf.h

Note - for linking to be successful I also needed to define LV_USE_DEMO_WIDGETS to avoid "undefined reference to `lv_demo_widgets'"
