    Hi Juan,
    Firs of all, thanks a lot for your answer to my other question.

    I have an issue trying to install my application into a iPad Retina (A6x)(32bits).
    When I use the simulator all works fine, but when I try to compile and install the application into my iPad the next error arises:

    ld: warning: ignoring file /usr/local/fuzzylite/bin_32bits/libfuzzylite-static.a, file was built for archive which is not the architecture being linked (armv7s): /usr/local/fuzzylite/bin_32bits/libfuzzylite-static.a
    Undefined symbols for architecture armv7s:
    “vtable for fl::Maximum”, referenced from:
    fl::Maximum::Maximum() in FuzzyLogic.o
    ……
    ……

    I have build fuzzylite-static.a for i386 and x86_64 and for both, and they compile and link ok for the simulator but not for the physical device.

    Is there any option I’m missing?

    Hi JuanRS,

    I am not familiar with iOS at all, but I believe you do not need fuzzylite-static.a in your iPad because your application is being statically linked. Hence, your application and fuzzylite library are both be contained within the same executable file.

    Can you try excluding fuzzylite-static.a from installation to the iPad? Perhaps it could be some sort of security error? I am also guessing that you are not compiling your application within the iPad, but just copying to the iPad.

    ipads/iphones are arm based devices – So unless you have updated the cmakelists.txt files to cross compile for arm, then its going to fail.

    (as to how to do that – Sorry, I’m a cmake noob!)

    (The simulator is intel based – so it will work fine)

    i wish i could be more helpful, but i do not have an iOS device to try, unfortunately. if you manage to compile correctly for iOS, please provide some hints on how to do it. cheers!
