Subject: Debugging why Build Rebuilds Something
Date: Thu, 21 Mar 2019 09:49:44 +0000	[thread overview]
Message-ID: <CS1PR8401MB118903B18389F649C68B4465B4420@CS1PR8401MB1189.NAMPRD84.PROD.OUTLOOK.COM> (raw)

I'm experiencing an annoying problem where OpenSslLib is constantly being rebuilt.  I don't think I've done anything unusual or different to it but nevertheless it gets built almost every time I rebuild the same platform.

I don't believe any source file timestamps are changing so I think this may be the build.py tool deciding to re-generate stuff.  (As a side note: does the Autogen process only run when changes are detected on dependencies?  I assume this must be the case otherwise everything would get rebuilt, right?)

Is there a debug flag that can be turned on to see why build might choose to rebuild something?  The normal build report and debug flags don't see to provide the information for "why" something is being rebuilt.

Thanks,

Eugene
