6 years ago I'm not entirely sure about the IBT and CrowdsaleIBT contracts without having a look at how you're using them, but the SafeMath ones are due to the fact that we use SafeMath libraries internally. You'll have to use our SafeMath library version.
Unfortunately, solc doesn't know how to handle cases where the contract names are the same, but come from two different locations.
Hi there!
Probably a super newbie error, but here it goes. When I try to start migrating the different smart contracts of my project to AragonOS I get several DeclarationErrors. I think the problem seems to be that I should be importing the compiled smart contracts differently if I develop within AragonOS framework, rather than the way it is done in a simple truffle project?
