missing required architecture x86_64 in file libCorePlot-CocoaTouch.a

Question

According to the Ray Wenderlich tutorial, I done the following :

Step 1 - I downloaded CorePlot_1.4.zip o

Answer 1

Try:

lipo -info libCorePlot-CocoaTouch.a

It's showing that the library is built for armv7, armv7s and i386 (32bit simulator) and that's not including the 64bit simulator. You'll have to build the lib for 64bit simulator and after that you can use lipo to add the 64bit lib to libCorePlot-CocoaTouch.a.

Output:

Architectures in the fat file: libCorePlot-CocoaTouch.a are: armv7 armv7s i386

PS: It's not going to work on iPhone 5S as well (no arm64).

EDIT:

Here are the steps you need to make in order to produce a binary that has both the arm64 and x86_64 architectures in it:

1. download CorePlot_1.4 from https://code.google.com/p/core-plot/downloads/detail?name=CorePlot_1.4.zip&can=2&q=
2. Open the Xcode project (CorePlot-CocoaTouch.xcodeproj) located in CorePlot_1.4/Source/framework
3. Select "Standard architectures" for "architectures" and "Latest iOS (iOS 7)" for "Base SDK"
4. Build the library (CMD+B)
5. Go to CorePlot_1.4/Source/build/ in the terminal
6. Run lipo -create ./Debug-iphoneos/libCorePlot-CocoaTouch.a ./Debug-iphonesimulator/libCorePlot-CocoaTouch.a -output core_plot_all.a
7. Add the newly created lib (core_plot_all.a) to your project
8. You're ready to go
