Error compiling for board Arduino/Genuino Uno.

This report would have more information with
“Show verbose output during compilation”
option enabled in File → Preferences.

I am not getting what all this information says. Please tell me what does it mean? I am not able to upload my sketch due to this error. I have checked my code a number of times but this error still exists. Please help me.

My code was:

int ledPorts={2,3,4,5,6,7,8,9,10};
int pin=9;

void steup()
{
for(int thisPin=0; thisPin< pin; thisPin++)
{
pinMode(ledPorts[thisPin],OUTPUT);
}
}
void loop()
{
for(int thisPin=0; thisPin < pin; thisPin++)
{
digitalWrite(ledPorts[thisPin],HIGH);
delay(100);
digitalWrite(ledPorts[thisPin],LOW);
}

for(int thisPin=pin; thisPin >=0; thisPin–)
{
digitalWrite(ledPorts[thisPin],HIGH);
delay(100);
digitalWrite(ledPorts[thisPin],LOW);
}
}

steup()

that should be setup()
