armv7

Our phonegap app builds fine for the iphone simulator but generates linker errors when building the app on an iphone. the only thing that changed was installing testflight and a test app. We already removed testflight and the test app, but the linker errors remain. Any ideas on how to fix this? We're on xcode 5 and phonegap 3.4. Errors: ld: warning: ignoring file /Users/c/Library/Developer/Xcode/DerivedData/s-fhgxmhdprdjvwahdbgwuagoragit/Build/Products/Debug-iphoneos/libCordova.a, file was built for archive which is not the architecture being linked (arm64): /Users/c/Library/Developer/Xcode

In compiling iPhone apps, there is a setting for "Optimized" architecture (armv7 only) vs a standard armv6/armv7 architecture. What are the benefits/consequences of compiling an armv7 only architecture? A smaller executable is a faster download from the app store. However, you do cut out non-armv7 devices . Unless your program requires OpenGLES 2.0 (which is only supported on armv7-supporting devices), you should compile the standard fat (armv6/armv7) binary. A fat binary is basically two (or more) Mach-O binaries glued together, with a single header page at the beginning. The performance cost

I'm working on an iOS app which supports iOS 4.3 and above. Due to some frameworks I cant Archive it for armv7s,so I have removed armv7s support. Will it reduce application performance? What is the advantage of using armv7s? Surprisingly there weren't a lot of differences in the machine code produced for the two different architectures; overall, the armv7s code does not look much different from the armv7 code. However, there were two specific differences that caught my eye. The first difference affects integer division. The armv7s architecture has two new integer division instructions that

Crash log contains "Binary Images" section with information about architecture (armv6/armv7) and identifier of all loaded modules. How to determine this information at runtime? (at least, just for application executable) NSBundle has method executableArchitectures, but how to determine which architecture is running? Alright time for the long answer. The mach headers of the dyld images in the application contain the information you are looking for. I have added an example that I only tested to work and nothing else so I would not recommend pasting it directly into production code. What it does

I have a 3rd party .a library, which is apparently compiled for only armv6 compatibility, where both new Xcodes (3.2.6 and 4), both now require a separate armv7 slice to run on the device. The link error is: file is universal but does not contain a(n) armv7 slice for architecture armv7. Anyone know how to make either of the two new Xcode operate as 3.2.5 did and accept the existing library while I'm waiting for the library vendor to cook up an armv7 version? In Project Settings, select "Standard" for the architecture (not "Optimized"). This should allow you to select "armv6" for the Active

I have built my own Static C++ Library, which is built with the settings: Architectures: armv7, armv7s Build Active Architectures Only: No Support Platforms: iOS Valid Architectures: armv7, armv7s The library project builds well and I got the .a file (I have cleaned the build folder and built the project again to be sure my settings were effective). I have added the library (.a file) to my iOS project, but the project won't build even though I have set the exact same settings on the iOS project: Architectures: armv7s, armv7 Build Active Architectures Only: Yes Support Platforms: iOS Valid

I have two 3rd party libraries. One just has a build for armv6 and the other just has a build for armv7. I need to use both of them in my iOS enterprise application. I've asked the armv6 library vendors to supply a armv7 version, but they haven't been able to do so. (Note: I've already got the answer and will provide it. Someone else asked this in a comment and there wasn't enough room to answer, so I've created its own question, and will provide my answer.) The answer is to hack the armv6 library into thinking it's an armv7 library. This will get you running until the vendor supplies the
