I added the protobuf<\/code> class \"xxx.pb.h\"<\/code>,\"xxx.pb.cc\"<\/code> in Project. I added a path\"\/usr\/local\/include\"<\/code> in Header Search Paths<\/code>, and added a path\"\/usr\/local\/lib\"<\/code> in Library Search Paths.<\/code><\/p>\n

Now I encountered a problem, The following error at Build:<\/p>\n

    Follow the steps mentioned in this answer -> http:\/\/stackoverflow.com\/a\/10279656\/1383704<\/p>\n
    There are a few pitfalls here and there, for which you may check my own answer for the same qn.<\/p>\n
    These were the steps I followed differently<\/p>\n
      \n
    1. \n
      instead of giving header search path till google directory, i gave the search path till the “src\/” directory<\/p>\n<\/li>\n
    2. \n
      In whichever you import your xxx.pb.h<\/code> you have to rename the .m<\/code> to .mm<\/code><\/p>\n<\/li>\n<\/ol>\n
      In Xcode 4.5 i was still getting some linker errors :<\/p>\n
      \n
      symbols not found for architecture i386<\/p>\n<\/blockquote>\n
      Because of this I wasn’t able to run on simulator. But the code will run on actual device.<\/p>\n<\/li>\n<\/ol>\n
