symbol(s) not found for architecture armv6

问题

Please help me from the below error.

I am working on graphs using 3rd party framework (libIPhonecharting), every thing works fine in simulator, but when I am trying to build .app file to install in IPAD Device I get the below error message.

ignoring file /Users/xyz/Desktop/xyzIPAD/library/4.0/Release-iphoneos/libIPhoneCharting.a, file was built for archive which is not the architecture being linked (armv6)

Here's how I got this problem:

I added a .h, .m and NIB from another project by dragging them onto my project navigator. Xcode didn't add them to the Build Phases properly.

My solution for this problem:

Go to the Target in the navigator menu
Click on the "Build Phases" tab
Add the .m file to "Compile Sources" (either drag it across, or use the + button)
Add the .xib to "Copy bundle resources"
Clean and build

It works for me thanks a lot to you

Few questions: Does you external lb have it's own project file? If so make sure that it is configured to build to arm6 and arm7 properly. Do the same for your main project file for good measure. Also, what version of XCOde are you on? There are significant differences between different versions.

Look at the libs scheme (depending on the version of XCode you are using) and make sure that is configured properly for debugging on the iOS device; I assuem you are building to your own device for debugging purposes: this recommendation is because of : "file was built for archive which is not the architecture being linked (armv6)"

After trying each of these things be sure to clean the entire project before each build.

Hope this helps. I feel your pain XCOde is evil.
