使用Swift编译静态库时出现错误“未知选项字符”X：-Xlinker“

添加swift文件进行编译到静态库时看到此错误。 使用XCode 6.0（6A215l）

我在这里创build了一个示例项目，错误发生在一个完全新鲜的项目中： https : //github.com/amleszk/SwiftTest/tree/cd94ca21d817fed336b1a3bfc774a13608e0d1ca

重现检出项目并构buildSwiftTest目标，该目标依赖于静态库。 任何帮助赞赏

Answer 1

更新：似乎Xcode 6的正式版本仍然有同样的问题。

从xcode 6 beta 2发行说明：

在这个版本中不可能build立包含Swift代码的静态库

Answer 2

我find了解决办法。 这是钩，但它的作品。 您应该以root身份执行此操作。

1. 转到默认的工具链bin目录

   cd $(xcode-select -p)/Toolchains/XcodeDefault.xctoolchain/usr/bin

2. 将当前的libtool重命名为old_libtool

   mv libtool old_libtool

3. 创build新的libtool

   touch libtool && chmod +x libtool

4. 插入当前脚本作为新的libtool的内容

    #!/usr/bin/python import os import subprocess import sys args=[] for arg in sys.argv[1:]: if arg != '-Xlinker' and arg != '-add_ast_path' and not arg.endswith('swiftmodule'): args.append(arg) args.insert(0, os.path.join(os.path.dirname(os.path.realpath(__file__)), 'old_libtool')) subprocess.check_call(args) 

5. 编译。
