Debug Hotspot with Eclipse (mac os 10.13)

安装gdb

brew install gdb

gdb的代码签名

主要目的是eclipse在debug的时候需要调用gdb，需要gdb有证书 具体的方法可以参照这个博客

安装eclipse adt插件

插件地址 注意在eclipse的安装软件导入链接就可以了

导入整个jdk工程

Run eclipse, choose "import project -> C/C++ -> Existing Code as Makefile Project", then click Next, enter the configuration page of the project:

• Project Name is hotspot, you can name yours
• Existing Code Location is /*/openjdk9/hotspot

Right click on hotspot project -> properties -> C/C++ General -> Paths and Symbols -> Source Location -> choose "Add Folder", add hotspot/src directory

Debug Configuration

Right click on hotspot project -> "Debug As -> Debug Configurations -> C/C++ Application -> New"

Main tab

• C/C++ Application: choose /opt/openjdk9/build/macosx-x86_64-normal-server-slowdebug/jdk/bin/java
• toggle Disable auto build

Debug tab
选最下面的Select other，选择LLDB-MI 。。。 的那一项

现在使用intellj的clion来调试比较好，如果用xcode的话，gdb对于mac os 13.x支持不好，还是换成lldb就好了

研究了一种使用vscode来调试的方法，下面是launch.json
