红帽全球峰会3.3. 检查调试符号的配置
您可以检查和设置调试符号的配置。
要获取安装的软件包列表，请输入以下命令：
sudo yum list installed | grep 'java-1.8.0-openjdk-debuginfo'
$ sudo yum list installed | grep 'java-1.8.0-openjdk-debuginfo'Copy to Clipboard Copied! Toggle word wrap Toggle overflow 如果没有安装一些调试信息软件包，请输入以下命令安装缺少的软件包：
sudo yum debuginfo-install glibc-2.28-151.el8.x86_64 libgcc-8.4.1-1.el8.x86_64 libstdc++-8.4.1-1.el8.x86_64 sssd-client-2.4.0-9.el8.x86_64 zlib-1.2.11-17.el8.x86_64
$ sudo yum debuginfo-install glibc-2.28-151.el8.x86_64 libgcc-8.4.1-1.el8.x86_64 libstdc++-8.4.1-1.el8.x86_64 sssd-client-2.4.0-9.el8.x86_64 zlib-1.2.11-17.el8.x86_64Copy to Clipboard Copied! Toggle word wrap Toggle overflow 如果要达到特定的断点，请运行以下命令：
gdb -ex 'handle SIGSEGV noprint nostop pass' -ex 'set breakpoint pending on' -ex 'break JavaCalls::call' -ex 'run' --args java ./HelloWorld
$ gdb -ex 'handle SIGSEGV noprint nostop pass' -ex 'set breakpoint pending on' -ex 'break JavaCalls::call' -ex 'run' --args java ./HelloWorldCopy to Clipboard Copied! Toggle word wrap Toggle overflow 以上命令完成以下任务：
- 处理 SIGSEGV 错误，因为 JVM 使用 SEGV 进行堆栈溢出检查。
-
将待处理的断点设置为
yes。 -
在
JavaCalls::call函数中调用 break 语句。在 HotSpot (libjvm.so)中启动应用程序的功能。
