identifier "xxxx" undefined

[NS.16]

i have project code when i compile it shows identifier is undefined

But i have included the path keil linker options and included header file also, i don't know why it shows like this.

when i click the definition of VL53L0A1_GPIO1_R_INTx it doesn't go to definition part.But the definition is written in the code.

Help me please.

my error:

..\..\Drivers\BSP\X-NUCLEO-53L0A1\X-NUCLEO-53L0A1.c(532): error: #20: identifier "VL53L0A1_GPIO1_R_INTx" is undefined

thank you in advance.

What exactly do you talk about ?

Working with an Eclipse toolchain?

Mind you, what the parser sees is not necessary what the compiler sees.

I am working in keil

So project perhaps lacks required command line defines, or include paths.

Lacks required include files.

Doesn't flag appropriate modules in stm32f4xx_hal_conf.h or equivalent.​

i have included the path of that file.

That was not the point.

If you e.g. place an "#error" preprocessor directive in the line above your definition of "VL53L0A1_GPIO1_R_INTx", does the build throw this # error ?

actually these file is working when the target is change to STM32F401RE.But now i working with STM32F429I

Sounds like you tried to change the target of your Cube/HAL application on the fly.

With such a delicate code generator like Cube, I would rather suggest to create a new project for the F429 target, and copy your added code.
