Question

我已经在armv6和armv7上为iPhone / iPad成功构建了boost c ++ 1_44_0库，但我似乎无法为armv7上运行的新设备创建构建。

在Github上使用BoostOnIphone和A-coding来创建构建，我需要的是Boost：armv7s架构上的线程，文件系统和系统库。

错误输出：

我的解决方案是使用终端验证库架构：

otool -h libraryFile.a

输出：

Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
 0xfeedface      12          9  0x00          1     3       1588 0x00002000

cputype和cpusubtype是要查找的值：

for armv7：

cpu类型：12 cpusubtype：9

for armv7s：

cpu类型：12 cpusubtype：11

现在我遇到的情况是我不可能将架构更新为第三方。所以我最终改变了我的Xcode构建项目：

Xcode设置（蓝色标签）
项目和目标架构：
有效架构仅添加了armv7
清理构建并再次运行

另一种解决方案是Hacking an armv7s library使用本教程。在我的情况下不起作用

为armv7上运行的iOS设备编译Boost c ++库
