Re: delivery on GCC 3.3 (was Re: Precompiled Headers and gcc 3.3)

Apple GCC 3.3 included in June 2003 Developer Tools release is GM version. It is ready for prime time.

One thing to watch out is that there are C++ ABI changes. So if your product uses C++ then you want to compile everything with GCC 3.3. If you're using third party library which has C++ interface then you want to get newer version of that library that is compiled using GCC 3.3. Similarly if you're shipping library with C++ interface then you want to explain this C++ abi mismatch to your customers.

AFAIK, Libraries and frameworks provided by Apple do not expose C++ interfaces, so you do not need to worry about it. (Let's not talk about IOKit and Kernel extensions at this moment:-)

If you find bugs in GCC 3.3, let us know asap so that we can fix them, if possible, in Panther.

I have a tangential question that I haven't heard addressed yet. Last year during WWDC, the point was hammered home that it wasn't a good idea to deliver products built with GCC 3.1 until Jaguar shipped. Is this as true now as it was then? I would imagine that the difference between GCC 2 and GCC 3 was much more significant than between 3.1 and 3.3, but does that mean it's okay to build deliverable products with the new compiler?

I've taken all my active projects and created a build style that calls GCC 3.3. I built them, then dealt with the warnings that came out of 3.3's stricter...ness. You know what I mean. The fact that GCC 3.3 is stricter than 3.1 means that some new warnings appeared, and I changed my code as necessary to make them go away. But I'm not building any products with 3.3 right now.

Is this the correct policy? Or is GCC 3.3 ready for prime time?

Has anyone managed to use pre-compiled headers with the Project Builder and the update to gcc? I'm assuming that it is not going to work with the standard UI and will require some sort additional build step? The compile time for my project is nearly unbearable without pre-comps!
