Build error

[g7kse]

I'm pretty sure its something I've done as I'm not familiar with PlatformIO. But, I thought I faithfully followed the instructions but it looks like I've come unstuck here and after a bit of going round in circles I thought I'd check the instructions.Particularly around the lv_conf.h note in issue#1

Screen looks a bit like this...

I would appreciate a bit of guidance to help cure the problems. Terminal output seems to have a few errors.

Looks o me that DateTime library and lvgl libraries are not being pulled in. I did add them to the .ini but that didn't fix it entirely but did get rid of a couple.

for reference I used this modified ini file

[env:esp32-s3-devkitc-1]
platform = platformio/espressif32
board = esp32-s3-devkitc-1
framework = arduino
build_flags = 
	-DARDUINO_USB_MODE=1
	-DARDUINO_USB_CDC_ON_BOOT=1
	-DBOARD_HAS_PSRAM

board_build.cpu = esp32s3
board_build.arduino.memory_type = qio_opi
lib_deps = 
        IanH/TRGBArduinoSupport
        mcxiaoke/ESPDateTime@^1.0.4
        lvgl/lvgl@^8.3.7

The leftover errors are:

#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (/home/alex/Documents/PlatformIO/Projects/TRGB Clock/src/main.cpp).

and

cannot open source file "../../lv_conf.h" (dependency of "TRGBSuppport.h")

The full output from the terminal is:

Hi,
same error here. :(

[osugiw]

Hi @SpaceTeddy @g7kse, I managed to solve the problems by declaring explicit path of the lv_conf.h. Please see the picture below:

Hope you find it helpful, Thanks!

[g7kse]

Its still a full on complain from my system. There must be some other issues with paths in there somewhere.

I'd pretty much given up on this before so thanks for the clarification.

[euphi]

lvgl uses some weird automatic to find the lv_conf.h include.

I also use a manual definition:

build_flags =
        -DBOARD_HAS_PSRAM
        -DLV_CONF_PATH=${platformio.include_dir}/lv_conf.h
        -DASYNCWEBSERVER_REGEX
        -DTRGB_ROUND

[extremerotary]

I had the same error, but was able to do it by manually writing the path. I will say though, that at first, even though I fully wrote out the path, it was being truncated and STILL couldn't find the file. So I went ahead and moved the file into c:/users/me/ directory and manually wrote that in, and THEN it was able to compile. I don't think I had any other issues that I can recall, but I'll be happy to help if you're still unable to compile it.
I would also note that in your output, you're only doing a run and not a run upload.

• Executing task: C:\Users\extre.platformio\penv\Scripts\platformio.exe run --target upload
  I'm not clear if that makes a difference in how it resolves dependencies and such, but wanted to point it out.

[AbidingOhmsLaw]

For me the issue seemed to be with the macro replacement
in the line:

 -DLV_CONF_PATH=${platformio.include_dir}/lv_conf.h

was getting replaced by C:UsersMikeDocumentsvscode-projectsTRGB-exampleinclude/lv_conf.h and was missing all of the slashes
The solution was to replace ${platformio.include_dir} with the full path

 -DLV_CONF_PATH=C:/Users/Mike/Documents/vscode-projects/TRGB-example/include/lv_conf.h

EDIT: also note that PlatformIO did not seem to like a directory paths with spaces in it, I originally had the projects folder named "vscode projects" but the macro seemed to stop at the space and would get replaced by "C:UsersMikeDocumentsvscode" still no slashes but it did show that there is and issue with spaces in the path as well.
