Are you using CMake 2.8.6...? Older CMake versions have not been used<br>
much on Lion. It wouldn't surprise me if 2.8.6 works, but earlier<br>
versions have issues...<br>

This:<br>
<br>
SET(CMAKE_OSX_ARCHITECTURES "$(ARCHS_STANDARD_32_BIT)")<br>
seems to result in a "standard" Xcode setting (armv7 (standard)) which is also set when you let Xcode create a fresh iOS app (from its own templates).<br>
<br>
But you also see this a lot on the fora:<br>
SET(CMAKE_OSX_ARCHITECTURES "$(ARCHS_UNIVERSAL_IPHONE_OS)"<u></u>)<br>
<br>
Not sure.<br>

There is a cmake variable that you set during onfiguration time.<br>
Something like os_x_architectures. There you can add the specific arch<br>
that you want to build for.<br>

I've got a build that works just fine with Leopard.<br>
<br>
For reasons I won't get into, I had to upgrade one of my systems to Lion and now (I've installed XCode 4.2) the build won't work. I get the following error:<br>
<br>

<br>
If I dig around, I find the CXX flags to be:<br>
<br>
-arch -O2 -fPIC<br>
<br>
and for some reason the Lion g++ compiler is choking thinking that there should be and arch value. Which if I dig around in the Leopard build I find:<br>
<br>
-Dxp_EXPORTS -arch i386 -O2 -g -fPIC<br>
<br>
Which brings up the questions, (1) with the same CMakeLists.txt file, why am I getting different values and (2) how do I get the arch to be i386 on the Lion build.<br>
