gdb - 如何使用 macports 在 Mac Mountain Lion 上配置我的 GDB 版本

Question

我刚刚使用 macports 通过 sudo port install gdb 在我的 Mac 上安装了最新的 gdb。问题是当我在命令行中输入 gdb 时，它仍然显示旧版本。如何切换到刚刚安装的新版本？ 谢谢。

Answer 1

类型:

port contents gdb

它告诉您端口所在的位置

 /opt/local/bin/ggdb
  /opt/local/include/ansidecl.h
  /opt/local/include/bfd.h
  /opt/local/include/bfdlink.h
  /opt/local/include/dis-asm.h
  /opt/local/include/gdb/jit-reader.h
  /opt/local/include/symcat.h
  /opt/local/lib/libbfd.a
  /opt/local/lib/libbfd.la
  /opt/local/lib/libopcodes.a
  /opt/local/lib/libopcodes.la
  ...

正如您在下面看到的，当您使用 MacPorts 安装它时，它被命名为 ggdb，而不是 gdb
