missing filename after '-o'

I'm new to writing in Arduino and am trying to program my "Ultimate Robot Kit Blue". In uploading my first motor test, an error message keeps coming up that says:

avr-g++: error: missing filename after '-o'
exit status 1
Error compiling.
Invalid library found in /Users/dennisleary/Documents/Arduino/libraries/Makeblock-Libraries-master: /Users/dennisleary/Documents/Arduino/libraries/Makeblock-Libraries-master
Invalid library found in /Users/dennisleary/Documents/Arduino/libraries/Makeblock-Libraries-master: /Users/dennisleary/Documents/Arduino/libraries/Makeblock-Libraries-master

I've been trying to get the robot up and running for quite some time now and any help would be greatly appreciated!

You probably have not installed the library correctly or with the correct name. However, you did not post your code and did not post the complete message so I am only guessing. I am not good at guessing. Please try again, following the instructions that follow.

To post code and/or error messages:

  1. Use CTRL-T in the Arduino IDE to autoformat your code.
  2. Paste the autoformatted code between code tags (the </> button)
    so that we can easily see and deal with your code.
  3. Paste the complete error message between code tags (the </> button)
    so that we can easily see and deal with your messages.

Before posting again, you should read the three locked topics at the top of the Programming Questions forum, and any links to which these posts point.

If your project involves wiring, please provide a schematic and/or a wiring diagram and/or a photograph of the wiring.

Good Luck!

Thanks, I reposted the question in the proper format with code and all. Should be easier to help fix my problem.

I am trying to program my "Ultimate Robot Kit Blue" for the first time and there seems to be an error with my library(?). This message keeps popping up when I try to upload the code onto my Makeblock Orion micro controller:

Arduino: 1.6.6 Hourly Build 2015/10/13 12:13 (Mac OS X), Board: "Arduino/Genuino Uno"

avr-g++: error: missing filename after '-o'
exit status 1
Error compiling.
Invalid library found in /Users/dennisleary/Documents/Arduino/libraries/Makeblock-Libraries-master: /Users/dennisleary/Documents/Arduino/libraries/Makeblock-Libraries-master
Invalid library found in /Users/dennisleary/Documents/Arduino/libraries/Makeblock-Libraries-master: /Users/dennisleary/Documents/Arduino/libraries/Makeblock-Libraries-master
Board at COM1 is not available

  This report would have more information with
  "Show verbose output during compilation"
  enabled in File > Preferences.

Here is the code itself:

#include "MeOrion.h"

MeDCMotor motor1(PORT_1);

MeDCMotor motor2(PORT_2);

MeDCMotor motor3(M1);

MeDCMotor motor4(M2);

uint8_t motorSpeed = 100;

void setup() {
  

}

void loop() {
  motor1.run(motorSpeed); /* value: between -255 and 255. */
  motor2.run(motorSpeed); /* value: between -255 and 255. */
  motor3.run(motorSpeed);
  motor4.run(motorSpeed);
  delay(2000);
  motor1.stop();
  motor2.stop();
  motor3.stop();
  motor4.stop();
  delay(100); :) 
  motor1.run(-motorSpeed);
  motor2.run(-motorSpeed);
  motor3.run(-motorSpeed);
  motor4.run(-motorSpeed);
  delay(2000);
  motor1.stop();
  motor2.stop();
  motor3.stop();
  motor4.stop();
  delay(2000);

}

Any help would be greatly appreciated!

More / Modify does actually work.

Did't see that option, I'll do that next time

1.6.6 hourly builds were bad, all of 1.6.6 is buggy as hell. Use 1.6.9 or 1.6.5r5 (not 1.6.10). Pretty sure that is a 1.6.6 build process bug that is now fixed
