Arrays and references don't mix
The following code produces several issues while linking. Removing the &array<SensorMessage> "fixes" the issue.
package main;
import platforms.xdk110;
struct SensorMessage {
var accX : int32;
var accY : int32;
var accZ : int32;
var temp : int32;
}
// BUG: make data a reference to see the goodness
fn mean(data : &array<SensorMessage>) {
let result : SensorMessage;
for(var i = 0; i < 10; i++) {
let sampleCount = 10;
let x = data[i];
result.accX += x.accX / sampleCount;
result.accY += x.accY / sampleCount;
result.accZ += x.accZ / sampleCount;
result.temp += x.temp / sampleCount;
}
return result;
}
Error message is:
ERROR | resolution of uriFragment '|1' failed.
