build fails

[ammaree]

I am trying to build using latest version of ESP-IDF Master ie v5.0 I am building from the command line, not using an IDE, on latest MacOS Ventura 13.0.1.

Getting the following error messages.

The warnings at the end I should be able to get rid of easily. The errors looks like the demo modules are not included. I have not go into the LVGL config at all, from previous experience with V7.x it felt like untangling spaghetti.

Any suggestions?

OK, got beyond those by enabling the demos and a number of additional fonts using menuconfig.

Also fixed (I think) a memory error asking for an increase in memory, changed to 40.

error Insufficient memory for lv_demo_widgets. Please set LV_MEM_SIZE to at least 38KB (38ul * 1024ul). 48KB is recommended.

Are these errors related to IDF v5?

That's odd. I'd have expected it to pick up the sdkconfig defaults, which includes the demos. Check the other LV_* config options starting from here, and make sure yours matches: https://github.com/radiosound-com/makerfabs-parallel-tft-lvgl-lgfx/blob/master/sdkconfig.defaults.esp32s3#L1444

Other than that, yes, that's a v5 deprecation. As v5 is still a moving target and I haven't seen any roadmap for if/when it will be released, I'd recommend sticking with 4.4 for now.

If you need >4.4 for other reasons but don't necessarily need the latest master, you might try the version of idf master I was on at the time I created this project, e899edd. That was about where I was when I thought to start fixing some of the build errors in LGFX. But I haven't been able to keep my "hobby" projects like this one up with the pace of changes since then. I am in the middle of hacking up ESP-ADF and a work project to build in the latest release/v5.0 branch, and it is a significant amount of work. (Latest master even failed to boot for me)

If you need to be on bleeding edge master, I don't know how much work it will be to bring LVGL and LGFX up to date with the deprecations and the stricter compiler. If you're lucky, just change ets_delay_us to esp_rom_delay_us and that's it. If you're unlucky, you'll dive down a rabbit hole of other deprecations, printf specifiers not matching the types, and other things like that.
