I've got a build that works just fine with Leopard.
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:
[ 0%] Reaping winning child 0x10260c510 PID 1009

If I dig around, I find the CXX flags to be:
-arch -O2 -fPIC
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:
-Dxp_EXPORTS -arch i386 -O2 -g -fPIC
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.
Best,
Dick Munroe
