TRY_COMPILE works fine for cross compiles, just not for *mutiple configs/architectures "simultaneously"* compiles...<br><br><div><br><div class="gmail_quote">On Thu, Jun 11, 2009 at 3:41 PM, Sean McBride <span dir="ltr"><<a href="mailto:sean@rogue-research.com">sean@rogue-research.com</a>></span> wrote:<br>

</div>Yeah, but gcc on 10.5 and earlier defaults to building 32 bit. If you<br>
want 64 bit you need to pass '-arch x86_64' (or ppc64). Or in the case<br>
of CMake, use CMAKE_OSX_ARCHITECTURES (or whatever its called).<br>
<br>
But if you use multiple architectures, like i386 _and_ x86_64, then each<br>
arch can and does have a different size void*. Now sure what CMake does<br>
there, hopefully warns or errors.<br>
<br>
Always best to avoid TRY_RUNs and I guess TRY_COMPILES too for Universal<br>
Binaries/cross compilation.<br>
