Working well in xcode 32-bit architecture. If i had arm64 architecture into the project it shows the following error
linked command failed with exit xcode 1
ignoring file /Users/edward/Documents/selva/projects/IAmThatIAmV3.0/api/lib/libfmodexL\_iphonesimulator.a, file was built for archive which is not the architecture being linked (x86\_64): /Users/edward/Documents/selva/projects/IAmThatIAmV3.0/api/lib/libfmodexL\_iphonesimulator.a
Please help me .Thanks in advance.

arm64 can only be used for devices and x86\_64 can only be used for the simulator. It looks like the two may be mixed up in your project? Can you confirm?

Thanks for your reply
I am sorry, I could not understand what you meant and I am new to iOS development. Could you please explain little more.
In my project I have set the Architectures like as follows
Architectures : Standard Architectures (armv7, arm64)
Valid Architectures : armv7, arm64

Yes, FMOD supports 64bit on iOS. Make sure you are linking the “\_iphoneos” library not the “\_iphonesimulator” library when compiling for the device.

When linking the FMOD library you can use -lfmod\_$PLATFORM\_NAME the variable $PLATFORM\_NAME will resolve to “iphoneos” when building for the device and “iphonesimulator” when building for the simulator.

I use -lfmod\_$PLATFORM\_NAME only but it is not working.
