CorePlot: how to run on device? (works OK on simulator)

Question

My app uses CorePlot and runs fine on simulator
(it accesses libCorePlot-CocoaTouch.a from:
/Users/myName/core-plot/build/Debug-iphonesimulator ).

To run on device, xcode expects libCorePlot-CocoaTouch.a in:
/Users/myName/core-plot/build/Debug-iphoneos
but that file is missing, so xcode gives error:
'/Users/Giovanni/core-plot/build/Debug-iphoneos/libCorePlot-CocoaTouch.a: No such file or directory'

I tried generating one by doing: CorePlot-CocoaTouch.proj > set Xcode to build on 'device' > 'Build And Run' but 'Build and Run' is grayed out.
Copying the simulator version obviously does not work.

Any ideas?

Answer 1

Consider adding CorePlot-CocoaTouch.xcodeproj as a sub-project and then add libCorePlot-CocoaTouch as a dependency.

Answer 2

Try opening the Core Plot project itself and building the framework first. You should build (not "Build and Run") the CorePlot-CocoaTouch target. Do it for each combination of SDK {simulator, device} and configuration {debug, release} (total of four builds). This will create the .a files you need.

After Core Plot is built, go back to your project and build it. It should now link and run correctly.

Check out my answer here if you don't want to use the CorePlot-CocoaTouch.xcodeproj import method (don't need to import the whole project, only the CorePlotHeader folder and the libCorePlot-CocoaTouch.a library file) Fix linker errors for Core Plot when using Xcode 5

Ultimately you might need to delete the old library by right clicking on your MyApp.app file in the Products folder and copy and past the new CorePlot_1.4 .a file into the Debug-iphoneos folder...clean, build, and it should run on an iOS 7 device.

SOLUTION: the issue was CorePlot-CocoaTouch.xcodeproj must also be added as Targets>MyApp>getInfo>DIRECT dependency (in addition to as subproject and in addition to libCorePlot-CocoaTouch being added as Targets>MyApp>getInfo>LinkedLibraries). Thanks
