Atmel Studio Failed compiling in expansion of macro round

[muluyilmaz]

After updating to 2.0.7 I got this error at ATmel Studio

arduino.h: 128:89: error: expected ';' before '}' token (long)_x - 0.5 })

Thanks for reporting. Are you using the round() function somewhere in your code?

The same message is being generated during expansion of the "constrain" macro. The DallasTemperature library uses this macro.

The last Version that work for me is Version 2.0.6 https://github.com/JensGrabner/snc98_Slash-Number-Calculator/tree/master/Software/Arduino/Projekte/snc98

The last Version that work for me is Version 2.0.6

What exactly is it that doesn't work since 2.0.6? Have you tried 2.0.8?

I use a lot of global variable -- my project ist not working - i cant say what it is? -- Start is o.k. but when i calculate 1/3 came a difuse display. other compiler - i use the Arduino IDE 1.8.13

You have all the changes here: https://github.com/MCUdude/MightyCore/releases

Just look through the commits and revert them on your computer to find out what causes the issue. It might be the new abs() macro.

[MCUdude]

You can try to replace the abs function with the pld implementation:

#define old_abs(x) ((x)>0?(x):-(x))
