OpenSSL 构建脚本在 Xcode 中作为'run script'阶段运行时失败(在 Xcode 外部成功)

Question

我正试图运行一个脚本，以在Xcode中作为"运行脚本"阶段构建适用于iOS的OpenSSL（armv6、armv7和i386）。

当从命令行作为独立脚本运行时，脚本会成功构建。结果是经过编译的libcrypto.a、libssl.a和include目录，其中包含标头。

然而，当我在Xcode中以运行脚本阶段的形式运行脚本时，它接近make的末尾，并错误地指出它找不到任何从libcrypto引用的符号。

shlib_target=; if [ -n "" ]; then 
        shlib_target="bsd-gcc-shared"; 
    fi; 
    LIBRARIES="-L.. -lssl  -L.. -lcrypto" ; 
    make -f ../Makefile.shared -e

我几乎可以肯定这是一个路径问题，但我不知道如何告诉Xcode（或脚本）要使用哪些路径。

这里提供的脚本需要修改，以考虑到最近对Xcode4.3开发工具位置的更改（即developer/不再位于根目录，而是实际上位于Xcode.app内）

以下是问题完整性的脚本：

Answer 1

尽管这是一篇较旧的帖子，但我认为问题仍然存在。但我想我找到了一个非常简单的解决方案。在调用"配置"或"制作"之前，只需在构建脚本中添加以下行：

export COMMAND_MODE=unix2003

这应该奏效。

Answer 2

它已作为一个问题记录在openssl上。

调整您的配置行：

./Configure darwin64-x86_64-cc zlib no-asm no-krb5 shared
