ios - clang 仅针对 iOS 设备目标失败，退出代码为 254

Question

我有一个 ios xcode 项目，可以为模拟器编译和运行，但无法为设备目标编译。

我正在尝试将 QT 项目移植到 iOS，但我的项目设置非常复杂。桌面版完全可以正常工作，除了删除所有与 UI 相关的代码外，我没有更改任何代码。

我已经向 apple 提交了错误报告(问题 ID:12103227)，但只是想知道以前有人遇到过类似的问题吗？

我正在使用 Xcode 4.4.1(4F1003) 和 Apple LLVM 编译器 4.0

Answer 1

我有“仅针对 iOS 设备目标的 clang 失败，退出代码为 254”。这是一个奇怪的目标，因为我有 2 个目标(免费和付费应用程序版本)。一个目标有错误，要修复我必须将build设置架构更改为 armv7。另一个目标在 armv6 上没有问题地归档。可能与 Admob 库有关，因为这是两个目标之间的唯一区别。
