Strange unit version error - Is DUnitX depending on DUnit or the other way around?

Question

I was using Delphi xe4 to compile https://github.com/hprose/hprose-delphi/blob/master/Test/HproseTest.dpr

And got the following error which I spent tens of minutes and still couldn't figure out why.

I've tried deleting all 'DUnitX*.dcu" and compile again, with no luck.

What puzzled me is that, why the unit TextTestRunner from DUnit (born first) relies on a unit from DUnitX which was born later?

Any hint? Thanks.

[dcc32 Fatal Error] HproseTest.dpr(37): F2051 Unit TextTestRunner was compiled with a different version of DUnitX.TestFramework.ITestListener

And here is the screenshot I made for making the problem description clear:

Answer 1

I downloaded the repository and it was compiling on the first try but i only have Delph XE8. But i found out that there is a unit called TestFramework.pas in DUnit and DUnitX. While TextTestRunner relies on DUnit, it can only find DUnitX's unit. So, I think you should check your Delphi librarypath.
