unable to compile due to errors

[alienkidmj12]

using the arduino tool im getting the following when trying to compile code

Arduino: 1.8.19 (Linux), Board: "LOLIN(WEMOS) D1 R2 & mini, 160 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 4MB (FS:1MB OTA:~1019KB), v2 Lower Memory, Disabled, None, Only Sketch, 921600"

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

See my reply to this here: #613 (comment)

Same solution, I was able to compile just fine after those changes. If it still wont work let me know and I'll walk you through it.

[alienkidmj12]

you mentioned this "This is an easy fix, you just need to make sure you have const before AsyncWebParameter.

Anything with request->getParam(1); should be request->getParam((size_t)1); Same applies if the number is not 1 or another index."

which files am i looking in for this ?

[alienkidmj12]

did that, and now i have further errors "

[alienkidmj12]

ah i think i fixed it :)

[cpawliuk]

If you still have any more problems you can reference the repo I uploaded with the corrections made here: https://github.com/cpawliuk/gbs-control-complete

[alienkidmj12]

thank you, im guessing i have to do the same fix going forward from github, or will someone fix it ?

[cpawliuk]

I'm not sure, but you'll get an error log anyways when you try to compile the code if there are any issues. If you're not sure what changes you need to make just post back and I'm sure someone will help.

However, from what I can see the compiler is requiring explicit type casting to size_t - so for getParam(1) you need it to be getParam((size_t)1) because getParam is an overloaded method, also due to implicit conversions.

The other error where you need to go from AsyncWebParameter *p = request->getParam((size_t)0); to const AsyncWebParameter *p = request->getParam((size_t)0); is just const correctness.
