armv7

问题 From android developer website, https://developer.android.com/distribute/best-practices/develop/64-bit it is clear that starting August 1, 2019, apps published on Google Play will need to support 64-bit architectures. Our current app has native libraries for armeabi-v7a, arm64-v8a, x86 ABIs but no x86-64. This is because one of the cordova plugins we are using doesn't provide X86-64 support. Will playstore reject the app update or pass it considering there is arm64-v8a support or we will have

问题 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

问题 i'm trying to use MBProgressHUD. i added header an .m to project, imported header in class and call MBProgressHUD from an ibaction in this way: -(IBAction)submitForm:(id)sender{ MBProgressHUD *HUD = [[MBProgressHUD alloc] initWithView:self.view]; [self.view addSubview:HUD]; HUD.labelText = @"Connecting"; [HUD show:YES]; } when i build project it happens an error: Undefined symbols for architecture armv7: "_OBJC_CLASS_$_MBProgressHUD", referenced from: objc-class-ref in FormViewController.o ld

问题 Today when i try to submit my app (update) to appstore, the Organizer told me : "iPhone/iPod Touch : application executable contains unsupported architecture(s): armv7s" I clearly remember that its last version was submitted with both armv7 and armv7s set and succeeded, but now Organizer changed its mind? to remove armv7s flag is simple, but my app is Universal, will the armv7s-removed app run on all iOS devices (iPhone 5 for example)? when should i build with aremv7s? Thank you. EDIT : xcode

问题 code is working fine on armv7 but compile for arm64 throws this "Declaration of ‘setxattr’ must be imported from module ‘Darwin.POSIX.sys.xattr’ before it is required" error. u_int8_t b = 1; setxattr([path fileSystemRepresentation], "com.apple.MobileBackup", &b, 1, 0, 0); any help plz? 回答1: I found the solution. include #include <sys/xattr.h> in the class 来源： https://stackoverflow.com/questions/34851876/declaration-of-setxattr-must-be-imported-from-module-darwin-posix-sys-xattr

问题 I'm having a question about the compilation on iOS. I'm generating a framework and it used to generate arm64, armv7 and armv7s (+ simulators with lipo and fun). The thing is, armv7s is not present in the binary anymore. Architectures in the fat file are: i386 x86_64 armv7 arm64 But I clearly asks in my XCConfig for VALID_ARCHS = arm64 armv7 armv7s. I verified that the XCConfig was indeed used and not overridden. I tried various google search but most of the time we find people not

问题 I have a fat static library compiled for armv7 and i386. In my iPhone/iPad project everything works fine, but i can only install my application on armv7 device so iPhone 3gs and up... There is a way to run my project on armv6 so i can install it on an ipod touch and an old iphone version (also if i disable the use of armv7 library). I try this: #ifdef _ARM_ARCH_7 ... //include and use of armv7 library #else ... //not include armv7 library #endif but when i compile my project i have link error

问题 Using the trivial C program below as an example. main() makes a function call to sum passing in 4 integer. sum() uses 4 locals. void sum(int a, int b, int c, int d); void main(void) { sum(11, 12, 13, 14); } void sum(int a, int b, int c, int d) { int x; int y; int z; int z2; x = a; y = b; z = c; z2 = d; } On my Ubuntu server 12.04.04 LTS I compile this program using arm-linux-gnueabi-gcc -S -mthumb func.c sum: @ args = 0, pretend = 0, frame = 32 @ frame_needed = 1, uses_anonymous_args = 0 @

问题 I'm trying to create an opcode to jump to an address. I looked in the manual and I see: B<c> <label> 31 30 29 28 | 27 26 25 24 | 23 ................. 0 cond 1 0 1 0 imm24 I don't understand what cond and imm24 are. How would I go about creating an opcode to branch to some address, for example branch to 0xbeffffbc ? 回答1: B is a relative branch of up to +/-32MB. The immediate encodes the signed offset of the target address from the current PC (i.e. this instruction + 8) - note that this offset

问题 I uploaded my app to Xcode where it says the build requires arm64. This excludes iPhones 5/5c and lower from using the app. However, I want iPhone 5/5c to be able to use the app and must have required arm64 by mistake. I think it must be something in the info.plist but have no idea. Things I have checked: (1) The info.plist does not have a RequiredDeviceCapabilities line. (2) Under Build Settings in Xcode, armv7, armv7s, and arm64 are all valid architectures. Any help you can offer would be
