SDK "iphoneos" cannot be located

在MAC下,交叉编译libvlc出现的一些问题和解决方法。
项目中使用了libvlc开源库。
在执行编译脚本中,遇到一句xcrun --sdk iphoneos --show-sdk-path报错

mac$ xcrun --sdk iphoneos --show-sdk-path
xcrun: error: SDK "iphoneos" cannot be located

查找原因:

mac$ xcode-select --print-path
/Library/Developer/CommandLineTools

发现是这个Xcode路径判断错误。

mac$ xcodebuild -showsdks
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

回想起最近安装了另外两个版本的Xcode,应该是这样导致了路径错误。

mac$ ls /Applications/Xcode
Xcode.app/ Xcode2.app/ Xcode3.app/

解决方法:给Xcode命令行工具指定路径

mac$ sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer/

再回头查看

mac$ xcrun --sdk iphoneos --show-sdk-path

目前编译libvlc的MAX机其他软件环境如下

mac$ sw_vers
ProductName:    Mac OS X
ProductVersion:    10.10.5
BuildVersion:    14F27
mac$ uname -a
