Discovery Options in Eclipse C/C++

Question

I'm not a programmer by trade and just recently decided to delve into using Eclipse C/C++ to program an ARM microcontroller and my problem is setting up the IDE. Basically, I'm following the direction from here: (https://openwsn.atlassian.net/wiki/display/OW/GNU+ARM) but after trying to run

int main(void){

int i = 0;
while (i < 10) {
   i++;
}
return i;

}

I get this error:

Which means that somewhere in the "Discovery Options" I've invoked 'arm-elf-gcc'. The problem is I don't know how to get to "Discovery Options" in the newest version of Eclipse C/C++ Kepler SR1. Can someone tell me where I can change it so I instead invoke 'arm-none-eabi-gcc'? When I go to Project Properties its no longer under C/C++ Build

Answer 1

Kepler hides "Discovery Options" by default. Go to Window->Preferences-> C/C++ > Property Pages Settings and check display discovery option page. Then, open your project preferences and change arm-elf-gcc to arm-none-eabi-gcc like the rest.

Answer 2

As you probably noticed, there is a new version of the GNU ARM Eclipse Plug-in available, which greatly simplifies toolchain PATH management.

Could you try it?

In case you still have problems, please use the GNU ARM Eclipse Plug-in support tracker.
