mac 使用源码包jdk

Question

今天想在mac下面用jdk的源码包安装java环境，结果报这个错误，不知道是啥原因，详情请看图

Answer 1

运行 file ./java 查看文件类型，Mac上的可执行文件一般是 Mach-O 64-bit executable x86_64 或者 Mach-O executable i386。

> file $(which java)
/usr/bin/java: Mach-O universal binary with 2 architectures
/usr/bin/java (for architecture i386):    Mach-O executable i386
/usr/bin/java (for architecture x86_64):    Mach-O 64-bit executable x86_64
