I recently got a I2c type LCD display by sun founder and i tried to test it by using the hello world code in order to see if it works or not. But the during the upload it shows an error message " error in compiling for arduino uno board". I tried all the online tricks i checked the address for the I2C connection, i added the libraries but still it wont work. I have Arduino Uno R3 board.
Then show the error first. Error during compilation means that something is incorrect in your source code or something is missing like a library. Without seeing the details we can guess.
Switch on verbose mode in preferences to see detailed info.
