Problem with a simple code

void setup() {

// put your setup code here, to run once:

pinMode(13,OUTPUT);

}

void loop() {

// put your main code here, to run repeatedly:

digitalWrite(13,HIGH);

}
I am using a home made Arduino. This is the error for the output.
Expand marco 'OUTPUT'
The error for the high is Expand marco 'HIGH'
These are the compiler errors.

Error while burning the bootloader: Error: 2 UNKNOWN: chip erase error: uploading error: exit status 1
Thanks in advance.

@gamalmot, your topic has been moved to a more suitable location on the forum.

Those are not compiler error but upload errors.

Please provide a schematic of your homemade board.
What is the processor on your homemade board? Are you trying to upload via ICSP or via USB? Does the procesor have a boot loader?

Please spend some time reading https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966; next apply what you've read / learned about code tags to the code in your post.
