在做的时候

gcc -v

我越来越

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin13.0.0
Thread model: posix

我试过通过自制软件安装gcc,但这没有用.还有什么其他解决方案？

解决方法

切换到旧版本的Xcode对我不起作用.相反,我使用了github： https://github.com/cowboyd/libv8/issues/107中的最后一个libv8修复程序

它完美地运作.
