 |
|
I got my Arduino starter kit this morning, and I was so excited to get started. I never dreamed it would be such a headache to set up! I figured it was open source, so naturally it would just work all spiffy-smooth with my Gentoo -- but nuh-uh.
After several hours of playing with this, I got the sketch app to run. Everything looks lovely. My Arduino Uno board is found on /dev/ttyAMC0, I have my programmer set to AVRISP mkII (tried AVR ISP as well).
The problem is when I go to verify some sketch code, it always gives me this error (even if there is no code at all):
| Code: |
/usr/share/arduino-1.0/hardware/arduino/cores/arduino/main.cpp:14: undefined reference to `loop'
collect2: ld returned 1 exit status
|
The contents of the main.cpp file:
| Code: |
#include <Arduino.h>
int main(void)
{
init();
#if defined(USBCON)
USB.attach();
#endif
setup();
for (;;) {
loop();
if (serialEventRun) serialEventRun();
}
return 0;
}
|
As you can see, line #14 is the line that says: loop();.
I have read the arduino instructions for Gentoo here:
http://arduino.cc/playground/Linux/Gentoo
And I have read this howto here:
https://forums.gentoo.org/viewtopic-t-907860-highlight-arduino.html
And hunted on the boards for insight, but I'm not finding anything. I have created all the symlinks suggested on the above post, but it still won't work. Something very fundamental (and I hope simple) is missing here... I just don't know what, since I really don't know anything about the arduino yet or how it works.
Any help is greatly appreciated. Thanks!

Ermm... okay I'm either smarter or stupider than I thought... 
It does work... but the instructions just need some work.
The code snippets from the sketch menu apparently cannot be run on their own. I typed in:
And the compile check worked just fine. 
So, I think it is working!
