Not able to compile truffle project

–1 vote

When I try to compile, I am getting some error regarding smart contract. But I am not understanding what it is because I dont know smart contract programming. Please help. I have mentioned the details below:

$ truffle compile

Compiling ./contracts/Hello-world.sol...
Compiling ./contracts/Migrations.sol...
Compilation warnings encountered:
/home/user/truffle/contracts/Hello-world.sol:7:4: SyntaxError: Functions are not allowed to have the same name as the contract. If you intend this to be a constructor, use "constructor(...) { ... }" to define it.
/home/user/truffle/contracts/Hello-world.sol:7:4: Warning: This declaration shadows an existing declaration.
   function Hello() {
   ^ (Relevant source part starts here and spans across multiple lines).
Compilation failed. See above.

Hi. If you look at the error logs, you will see the reason behind this error:

Functions are not allowed to have the same name as the contract.

So, change the contract name or the function name. If you don't wish to do this, then you will want to define this function as a constructor. 

contract abc {
...
...
...
function abc() public {
...
...
...
}
}
