Missing file-errors in some cases of #define

Software IDE 2.x
1

Hi
i have a code here, and i wanted to start to put in some output to the serial terminal to test it a bit.
To be able to enable or disable the terminal output i created a line this way:

#define SER 1

//#define NEOLED_INIT 1
//#define NEOLED 1
#define OLED_INIT 1
#define OLED 1
#define USBMIDI 1
//#define STDMIDI 1
#include <EEPROM.h>
#ifdef OLED_INIT
  #include <SPI.h>
  #include <Wire.h>
  #include <Adafruit_GFX.h>
  #include <Adafruit_SSD1306.h>

  #define OLED_RESET -1
  #define SCREEN_WIDTH 128 // OLED display width, in pixels
  #define SCREEN_HEIGHT 64 // OLED display height, in pixels

  Adafruit_SSD1306 OLEDMatrix(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);
#endif

This line brings the following error:

/home/tutorius/Arduino/USB-Midi1/midi-nano/midi_micro_new_ino/midi_micro_new_ino.ino:9:10: fatal error: EEPROM.h: No such file or directory
   #include <SPI.h>
          ^~~~~~~~~ 
compilation terminated.

I can change this code by removing the line 2.

/home/tutorius/Arduino/USB-Midi1/midi-nano/midi_micro_new_ino/midi_micro_new_ino.ino:10:12: fatal error: SPI.h: No such file or directory
   #include <Wire.h>
            ^~~~~~~

Two lines free:

/home/tutorius/Arduino/USB-Midi1/midi-nano/midi_micro_new_ino/midi_micro_new_ino.ino:10:10: fatal error: EEPROM.h: No such file or directory
   #include <Wire.h>
          ^~~~~~~~~~
compilation terminated.

Three lines free:

/home/tutorius/Arduino/USB-Midi1/midi-nano/midi_micro_new_ino/midi_micro_new_ino.ino:11:10: fatal error: EEPROM.h: No such file or directory
   #include <Adafruit_GFX.h>
          ^~~~~~~~~~
compilation terminated.

The version with five inserted blank lines can be compiled...

I have read about comparable error-messages in this forum from 2017, long ago. Any solutions?

Used IDE:

Version: 2.2.1
Date: 2023-08-31T14:16:33.536Z
CLI Version: 0.34.0

Using Linux and the Appimage.

Thanks a lot.

SER might be a reserved word. What happens if you change it to SERDBG?

Changed it to SERD, same behaviour.

When its a reserved word, it should not work in every case. I can't see a way that a reserved word works well with much blank lines after it.

I have added some more #defines afer SER (SERD), and the free lines are still needed, after the last #define.

Which board are you compiling for?
If you copy the code from your initial post and paste it into a new sketch, do you still get the same errors? I have no problem compiling it here on the same version of the IDE on linux.
