FPC 2.7.1 Compilation Aborts without Error

[jasonrobert]

I've just started using Lazarus 1.1 with FPC 2.7.1 and I'm trying to port around 460 files to FPC.  It compiled the first couple of units I added to my project just fine which had no dependencies on other units, (typex.pas and numbers.pas).  But then it seems to get mad at me once I added my third unit betterobject.pas, which is a TObject replacement and introduces dependencies on BetterObjectRegistry.pas, OrderlyInit.pas, Generics.Collections.pas, better_collections.pas and so on. 

The compilation just aborts without any real error, just a few warnings and hints.   Short of just giving you my 2+ million lines of code, does this log mean anything to anyone?

try to minimize the problem. Just shave off units in a copy till you can reproduce it with a few files. Then post that to bugtracker

[jasonrobert]

If I had to make a guess.   I think that this is somehow related to circular references.  systemx references betterobject in the interface which references back to systemx in the implementation.   I have no choice but to keep digging I guess.

[marcov]

Even then there is usually some "can't find unit xxx' message.  Make sure your compiler output log reflects both stdout and stderr though.

[jasonrobert]

I narrowed it down using some {$MESSAGE} directives.... it didn't want to compile some constructor which contained a call to TList<TSomeObject>.create ... I reported the bug.
