Warning for Assert.sol - shadows an existing declaration #179

Closed designium closed 6 years ago

designium commented 6 years ago

I am doing the Pet Shop example and in the test part of the tutorial, the truffle test gives back the following warnings:

Using network 'development'.

    Compiling ./contracts/Adoption.sol...
    Compiling ./test/TestAdoption.sol...
    Compiling truffle/Assert.sol...
    Compiling truffle/DeployedAddresses.sol...

    Compilation warnings encountered:

Does it help if we change the comparison from that to:

uint32 constant A = uint32(byte('a'));

??

Just going through the tutorial myself and getting the same warnings. Is this anything to worry about?

arkryonia commented 6 years ago

Same thing for me.

howtomakeaturn commented 6 years ago

same here. why the warning message comes out?

HaleTom commented 6 years ago

Work around: 

yarn global add truffle@beta
bmmpxf commented 6 years ago

Hi there all. This tutorial has been updated and this issue should not be there anymore. Please give it another try!

@bmmpxf What was the change? Because I'm getting it in a personal project as well.
