Issue #82 | 状态: 已关闭 | 作者: macdroid53 | 创建时间: 2018-11-13

I can’t seem to get the mega version to override the grbl files in that come with the Arduino 1.8.7. This is on Ubuntu 18.04. If I attempt to build I get pages of warnings like this:

In file included from /home/mac/Arduino/libraries/grbl/grbl.h:43:0,
from /home/mac/Arduino/libraries/grbl/examples/grblUpload/grblUpload.ino:27:
/home/mac/Arduino/libraries/grbl/nuts_bolts.h:56:0: warning: "max" redefined
#define max(a,b) (((a) > (b)) ? (a) : (b))
^
In file included from sketch/grblUpload.ino.cpp:1:0:
/home/mac/Downloads/Arduino/arduino-1.8.7/hardware/arduino/avr/cores/arduino/Arduino.h:93:0: note: this is the location of the previous definition
#define max(a,b) ((a)>(b)?(a):(b))
^

You need to follow the compiling instructions exactly. Grbl hacks how the Arduino IDE works to allow compiling of Grbls custom firmware.

Sorry…please point me to “the compiling instructions”. Because I got it working on one pc, but not this one and I can’t find “compile grbl this way for mega 2560” instructions.

Compiling Instructions.

I believe the only difference is selecting the Mega2560 as your board in the Arduino IDE. The problem you are getting is usually related to not using the GrblUpload example file, having another copy of Grbl in your Arduino library path, or not correctly importing Grbl as a library.

Ok, from that, (now bookmarked, thank you!), link:

“NOTE: If your environment is clean and Arduino IDE compiler still throws “warning: […] redefined” messages, you may need to uncheck File -> Preferences -> “Aggressively cache compiled core”.”

Once I unchecked that it compiles fine. Apparently, something was cached. :(

PS, is there a grbl specific forum somewhere? I’m having some other issues with limit/reset inputs I’d like to discuss…and github probably isn’t the right place.
