我试图在Xcode中的“run script”阶段运行一个脚本来构建适用于iOS（armv6、armv7和i386）的OpenSSL。当作为独立脚本从命令行运行时，该脚本成功构建完成。结果是编译后的`libcrypto.a`,`libssl.a`和包含头文件的`include`目录。但是，当我将脚本作为“run script”阶段在Xcode中运行时，在进行到make的末尾时出现错误，指出无法找到从`libcrypto`引用的任何符号。
我几乎可以确定这是一个路径问题，但我无法弄清楚如何告诉Xcode（或脚本）使用哪些路径。 这个脚本在这里，需要修改以适应Xcode 4.3中开发工具位置的最近更改（即Developer /不再位于根目录，而实际上在Xcode.app内部）。 为了完整起见，这是问题的脚本：

BSD-generic32而不是darwin-x86_64，而且iOS也不允许使用共享库。我尝试了使用我的BSD进行配置，并且没有使用共享选项，但我得到了与我在原始问题中所述相同的错误。 - Jasarien
