Hi everybody, I’m pretty new on Xcode 4.2, so maybe somebody can help me. 1. I’m trying to add Qt4.8 libraries to my Xcode Project. I have followed the steps of this web but I have any success. The program is built and run on Terminal but It doesn’t work on Xcode. I’ve been looking for in Google and It seems there’s no solution yet. Is it true ?. 2. I wanna work with Augmented Reality so I’m trying to install ARToolKit 2.72. I follow the intructions on this web cd ~/Desktop tar zxvf ARToolKit-2.71.tgz cd ~/ARToolKit ./Configure make cd bin ./simpleTest but the result after the make command are two errors make: *** [video.o] Error 1 make: *** [all] Error 2 make: *** [all] Error 2 Someone knows why have I these problems? I have a MacBook Pro (early 2011) with Mac OS X Lion. Thank you very much.
