B4R Question rLiquidCrystal-Library(1.0) -- > problem to compile

[newbie]

Hi,

today i have try to work with the rLiquidCrystal-Library to work for a simple project with old LCD-Displays.
I have try the Sample code

Sub Process_Globals
    Public Serial1 As Serial
    Private lcd As LiquidCrystal
End Sub

Private Sub AppStart
    Serial1.Initialize(115200)
    Log("AppStart")

    lcd.Initialize(8, 255, 9, Array As Byte (4, 5, 6, 7))
    lcd.Begin(16, 4)
    lcd.Write("waiting for time")
End Sub

gives a compiler Error

Has somebody suggestions ?

The library is probably not compatible with this board.

Try to add this line to rLiquidCrystal.cpp:

extern void *operator new( size_t size, void *ptr );

Hi Erel,
this insert don`t works. I have change to inline C, that works.

But in the meantime i think it is another problem.
The last year i have only worked with ESP32Dev-Moduls
A simple commandline like

x = NumberFormat(Temp,2,1)

gives a similar error everytime when i have a arduino board selected (Due , uno ..).
A ESP32 board gives me no compiler Errror

Have you a idea what is wrong in the IDE ??

 

[Erel]

Which version of B4R are you using? Please upload a project that doesn't compile with UNO as the target.

I am using version 3.5

Same in the actual Version

It compiles fine here, after I've added a reference to rDHT library.

My guess is that you modified rCore.h at some point. Delete B4R and install it again.
