我正在尝试为ios7构建Botan lib（32位和64位ios设备）
我试过了：

如何配置IOS_SYSROOT？我用的是XCode5。不应该默认设置？该怎么办？为什么它使用MacOSX平台...
这是我运行setenv-ios时的输出
./setenv-ios.sh
Configuring for Device (ARMv7)

这实际上可能有用......但它没有
答案 0 :(得分：1)
我不确定，但你可以尝试一下......
以配置IOS_SYSROOT
如果您是从命令行执行此操作：
. ./setenv-ios.sh
export CPP="cpp"
export CC="clang -arch armv7 -arch armv7s --sysroot=$IOS_SYSROOT"
export CXX="clang++ -arch armv7 -arch armv7s s--sysroot=$IOS_SYSROOT"
./configure --host=x86_64-darwin --host=arm --with-sysroot=$IOS_SYSROOT ...
如果要为ARM64构建，则可能需要添加 -mios版本分钟= 7.0。在编译时，OpenSSL不需要它 Clang，而Crypto ++和libevent，以及libcurl都做到了。
