Hi,

I’m having some problems with using blur2d combined with the XY foroward declaration. When compiling, I’m getting the following errors:

[-Wunused-variable]
C:\Users\Timo\AppData\Local\Temp\build6446048778024317284.tmp\FastLED\colorutils.cpp.o: In function `blurColumns(CRGB*, unsigned char, unsigned char, unsigned char)’:

libraries\FastLED31/colorutils.cpp:415: undefined reference to `XY(unsigned char, unsigned char)’

I have stumbled upon some solutions, but none of them will work for me. It surprises me a bit because I never had problems combining blur2d with the XY(x,y) function.

Anybody knows how I can solve this? I am using a teensy 3.2 with OCTOWS2811 adapter, running the most recent version of fastLED.

Here’s my code: https://bitbucket.org/snippets/TimoLejeune/9KbKR

Thanks a lot for your help in advance! :slight_smile:

Your function is defined wrong - the definition for XY should be:

uint16_t XY( uint8_t x, uint8_t y);

You have

uint16_t XY( int x, int y)

Those two functions have different types (an int is not the same as a uint8_t) - and so the compiler doesn’t line them up the way you’re expecting.

And once again it turns out easier than I anticipated. Thanks a lot Daniel, it works like a charm now!
