Library error (Pixy2CCC.h) / Error messages when compiling Arduino sketch

Pixy Software
#1

Dear Pixy2 developers!

I’m trying to use Pixy2 for a fetch robot.
https://forum.arduino.cc/index.php?topic=672547.0

However, when compiling the sketch I get:

In file included from /home/…/fetch_robot_pixy_servo_v3/fetch_robot_pixy_servo_v3.ino:2:0:
/root/Arduino/libraries/Pixy2/Pixy2CCC.h: In member function ‘int8_t Pixy2CCC::getBlocks(bool, uint8_t, uint8_t)’:
/root/Arduino/libraries/Pixy2/Pixy2CCC.h:124:32: error: ‘PIXY_TYPE_RESPONSE_ERROR’ was not declared in this scope
else if (m_pixy->m_type==PIXY_TYPE_RESPONSE_ERROR)

So I manually declared those variables in Pixy2CCC.h. But not sure, if this is the way tho solve this problem.

Any help greatly appreciated.
Thank you!

Hmmm…perhaps @edge can decipher this?

Hello,
It looks like you need to include “Pixy2.h”, which includes all other files including pixy2CCC.h, etc.

Hi Edward,
“Pixy2.h” was always included in the sketch.

#5

That’s odd…

So Pixy2.h includes TPixy2.h which has the #define for PIXY_TYPE_RESPONSE_ERROR.

Something isn’t quite right…

You might reinstall the Pixy2 Arduino library.

I re-installed the libraries and tried to compile an empty sketch.
On Linux (Arch) I get the same error message.
On Windows it’s a little different.

Ah, by including the files like you have, it messes with the “include once” #defines.

Just use 1 include statement:

#include “Pixy2.h”

Look at the ccc_hello_world example if you need an example.
