rom/miniz.h error still occurs when compiling for Core with board def 3.2.x
-
Only since the board def "updated" automatically from ver 2.1.4 to ver 3.2.x, I cannot compile my trusty, dusty Core Basic (Or Core2).
/Arduino/libraries/M5Stack/src/utility/pngle.c:31:10: fatal error: rom/miniz.h: No such file or directory
If I downgrade to 2.1.x it compiles as usual for 5 years running.
I found this on google:
https://www.gonnalearn.com/from-miniz-h-compilation-error-m5stack-arduino/
and there have been some other reports on this very community site.
https://community.m5stack.com/topic/7569/issue-with-core2-libraryMy Arduino IDE ver2.3.6 asks me EVERY DAY to upgrade to M5Stack board def 3.2.x.
This is getting tedious. Ver 3.2.1 recently added did not help.Is M5Stack abandoning the older Cores?

The rom/miniz.h error occurs because newer board definitions (3.2.x) removed legacy ESP32 support. Downgrading to 2.1.x works, but to fix it permanently:
Manual fix: Replace #include <rom/miniz.h> with #include <miniz.h> in pngle.c (as noted in the linked guide). Disable auto-updates: In Arduino IDE, go to File > Preferences and uncheck "Check for updates on startup."
M5Stack isn’t abandoning older Cores, but newer SDKs drop deprecated APIs. If issues persist, stick with 2.1.x or modify the library.
