Hi I have a question regarding?architecture?build targets for iPhone. I use the normal way to build PJSIP for an iphone: $ ./configure-iphone $ make dep && make clean && make But in the terminal I do not see any indicator about the architecture being built against. When i looked inside configure-iphone scrip i noticed that ARCH is commented out #ARCH="-arch armv6" With this I get hundreds of CPU_SUBTYPE_ARM_ALL warnings but not sure which architecture causes them to appear. I would be grateful if some sheds some light on this I am using XCode 3.2.6 and SDK 4.3.1 and PJSip 1.10 Cheers
