Hi, I am new to Mac development, currently handling a transition of 32 bit Mac application to support both 32 and 64 bit arch. I am using XCode3.0 to build x86_64 arch. I am successful in building the application, But When I run the application in "Snow Leopard (Build 10A190)" getting an error "Cannot execute binary file". I confirmed, application is x86_64 bit arch by file command. Can anyone guess whats the issue...? Thanks in advance.
