Question

我最近在Xcode上编译时遇到了一个独特的错误。有问题的应用程序是我从github获得的一个名为sios的应用程序。错误是：

clang: error: unknown argument: '-mstructure-size-boundary=32' [-Wunused-command-line-argument-hard-error-in-future]
clang: note: this will be a hard error (cannot be downgraded to a warning) in the future
clang: error: unknown argument: '-falign-loops' [-Wunused-command-line-argument-hard-error-in-future]
clang: note: this will be a hard error (cannot be downgraded to a warning) in the future
clang: error: unknown argument: '-falign-labels' [-Wunused-command-line-argument-hard-error-in-future]

clang: error: unknown argument: '-falign-jumps' [-Wunused-command-line-argument-hard-error-in-future]
clang: note: this will be a hard error (cannot be downgraded to a warning) in the future
clang: error: unknown argument: '-fpeel-loops' [-Wunused-command-line-argument-hard-error-in-future]
clang: note: this will be a hard error (cannot be downgraded to a warning) in the future
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

如何解决这个问题？

Answer 1

您必须与开发该代码的人交谈。那些是未知的构建参数，Xcode 5.1包含一个拒绝它们的新版本的clang（而不是让它们被忽视，这就是之前发生的事情）。

或者，使用Xcode 5.0进行编译。（请参阅我的讨论here，了解Xcode 5.0和5.1如何能够并存。）

Answer 2

删除＆＃34;未知＆＃34; clang中引发的错误中列出的参数，来自xcode中构建设置下的SNES_CFLAGS。它会成功编译然后;-)

在Xcode 5.1上编译错误
