Compiling

[islcom]

Hi, have an issue compiling example.
from Arduino/libraries/BaseSupport-master/examples/BaseExample/BaseExample.ino:6:
Arduino/libraries/BaseSupport-master/BaseSupport.h:74:23: note: declared here
74 | void ICACHE_RAM_ATTR delaymSec(unsigned long mSec) {
| ^~~~~~~~~
Arduino/libraries/BaseSupport-master/BaseSupport.h: In function 'int wifiConnect(int)':
Arduino/libraries/BaseSupport-master/BaseSupport.h:141:11: error: control reaches end of non-void function [-Werror=return-type]
141 | WiFi.mode(WIFI_STA);
What am I missing?

Thanks

I have just done a check compiling the example. It succeeded with no errors.

I suspect your environment is having some issue with the ICACHE_RAM_ATTR which signals that the function should be saved in the cache and executed from there.

It is possible your environment needs the new version of ICACHE_RAM_ATTR which is IRAM_ATTR. You could try replacing those instances with the newer version.

What Arduino version are you using and what Arduino esp8266 package have you used?

Thanks, Using Arduino IDE 1.8.13 on Debian 11, 1.18.19 & 2.2.1 on Win 10, all have same result. Changed ICACHE_RAM_ATTR to IRAM_ATTR and file system to littleFS. Compiles if I add return 1; on line 142 of BaseSupport.h

Have downgraded generic esp8266 from 3.1.2 to 3.0.0. It now compiles. Am constructing the WiFiPowersupply. Thanks

Thanks for that.
It looks like the later esp8266 still supported the deprecated ICACHE_RAM_ATTR but I have changed that to IRAM_ATTR anyway

However, the wifiConnect function is declared as a int function but had a path which didn't return a value. It looks like the later compiler is more picky about this whereas previous versions were OK with it. None of the calls to wifiConnect required a return value but I have added the final one to ensure it compiles OK.

Thank you for the interesting projects. Appreciate the work involved. Regards John M
