Compiler #error directive not working for arduino

Development Platforms
1

For several month I’m working succesfully with platformio.
Today I got stuck when I wanted to stop compiling with the following statement:

#ifndef VERSION1
#error “befor compiling define ‘VERSION’ in your platformio.ini file”
#endif

The directive #error doesn’t have any effect.
Can anyone give an advise?

Thank’s, Heinz

This from a test compilation I just set up:

Building in release mode
Compiling .pio/build/uno/src/main.cpp.o
Compiling .pio/build/uno/FrameworkArduino/HardwareSerial.cpp.o
src/main.cpp:4:2: error: #error "HELLO should be defined. Compilation aborted."
 #error "HELLO should be defined. Compilation aborted."
  ^~~~~
*** [.pio/build/uno/src/main.cpp.o] Error 1

And this is the code, it’s just the blink sketch with a #error added.

#include <Arduino.h>

#ifndef HELLO
#error "HELLO should be defined. Compilation aborted."
#endif

void setup() {
  pinMode(13, OUTPUT);
}

void loop() {
  digitalWrite(13, HIGH);
  delay(1000);
  digitalWrite(13, LOW);
  delay(1000);
}

and platformio.ini:

[env:uno]
platform = atmelavr
board = uno
framework = arduino

Seems to be working fine for me. You don’t by any chance have the variable defined somewhere do you? In the source? in platformio.ini? in a header file?

Cheers,

Hello Norm,
thank you for your fast reply. I tested your example on my system and it worked fine for me as well. So I’ll start the exhausting search in my project to find the reason.

Cheers, Heinz
