compile error multiple definition of `Wire'

[GuttalBug]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

I am trying to use soft_i2c_eprom, I use the following declaration:

#if NO_EEPROM_SELECTED
 //#define EEPROM_SETTINGS
 #define I2C_EEPROM
 #define SOFT_I2C_EEPROM
 #undef I2C_SDA_PIN
 #define I2C_SDA_PIN                           70
 #undef I2C_SCL_PIN
 #define I2C_SCL_PIN                           71
 #define MARLIN_EEPROM_SIZE                    0x7FFF  // 32K (25LC256)
 #undef NO_EEPROM_SELECTED
#endif

but wen I compile with Visual Studio Code I get the duplicate "Wire" definition error. If I remove the #define I2C_EEPROM statment I can compile but Marlin use eeprom emulation.

Since BOARD_CABER is totally custom,we have no idea what platform this is on and absolutely no way to even start looking at this

You need to provide sufficient information so we can replicate the issue.

No Boards pin.h file
No build environment details
Not even a error log.

Thanks for the answer, I include the the pin definition for BOARD_CABER.
pins_CABER.zip
The solution that I have found is to modify eeprom_if_i2c.cpp renaming "wire" to "wiregg".
eeprom_if_i2c.zip
The solution work perfectly but I don't know if there is a more elegant solution

[GuttalBug]

sorry I closed for mistake

[selahattinerdal]

Same problem. I have changed in eeprom_if_i2c.cpp

#if ENABLED(SOFT_I2C_EEPROM)
  #include <SlowSoftWire.h>
  SlowSoftWire Wire = SlowSoftWire(I2C_SDA_PIN, I2C_SCL_PIN, true);
#else
  #include <Wire.h>
#endif

to

  #include <Wire.h>

and its worked.

[GuttalBug]

with your solution you still use hardware I2c and not the SlowSoftWire that alluw to use any I/O pin

[thinkyhead]

The pins files define (or don't define) SOFT_I2C_EEPROM. So the simpler solution is to not define it in your pins file.

[GuttalBug]

But if I not define SOFT_I2c_EEPROM how can use generic I/O pins for I2C bus ?

This was probably fixed in #25707.

Please download bugfix-2.1.x to test with the latest code and let us know if you're still having this issue.

[GuttalBug]

I test with the last build and the problem is fixed. Thanks to all
