我的开源
Hotspot调试环境搭建-基于Ubuntu16.04.7-OpenJDK8u-Clion
1 安装版本管理工具.
命令:
sudo apt install mercurial
说明:
mercurial 是OpenJDK的版本管理工具.类似于GIT. 没有深入使用. 基本使用方法与git可以相通.
比如下载/克隆代码:hg clone http://hg.openjdk.java.net/jdk8u/jdk8u
注意:
进行安装hg时,会报一个错误:Unable to acquire the dpkg frontend lock. 可能的解决文档: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)我是直接重启后解决了些问题.
2 设置代理
类似于git下载国外的仓库会非常的慢.
hg的仓库下载也可以使用代理进行.可以提速
在个人home目录~下创建文件:.hgrc内容如下.=>更详细介绍请点击<=
[http_proxy]
host=http://[username]:[password]@[proxy_host]:[port]
友情提示:
如果没有代理.你也可以从其它github的源进行下载. 但是..... github在没有梯子的时候.也是一样的慢.
这似乎是一个死循环. anyway. 先下载代码.
3下载代码
这里的下载代码实际是两部分:
使用上面给的地址下载的是一个壳工程. 类似于一个父工程.
在下载的工程文件里面有一个文件:get_source.sh,需要再次执行这个脚本才能下载到完整的代码.
cd sourcedir
hg clone http://hg.openjdk.java.net/jdk8u/jdk8u
# 此时已经在sourcedir目录有一个仓库: jdk8u
cd jdk8u
sh ./get_source.sh # 如果没有执行权限可以先执行 chmod u+x get_source.sh
# 执行完成就会得到一个完整的仓库代码.
注:
上面的get_source.sh一定是需要使用 hg clone下载的带版本信息的仓库才能执行. 如果是通过别人说的方法下载的zip包的源码文件,是不能执行的. 切记.
4 预装依赖
安装GCC
sudo apt-get install gcc g++ gdb make

安装依赖
sudo apt-get install \
libasound2-dev \
libfreetype6-dev \
libcups2-dev \
libfontconfig1-dev \
libxext-dev \
libxrender-dev \
libxtst-dev \
libxt-dev
5 安装BOOT JDK
此步骤略. 可以使用华为的JDK官网镜像下载. 然后使用java开发常用的绿色解压方式使用.

6 编译配置
sh ./configure --with-debug-level=slowdebug \
--disable-zip-debug-info \

--with-freetype-include=/usr/include/freetype2 \
--with-freetype-lib=/usr/lib/x86_64-linux-gnu/

7 进行编译
这里使用一个bear命令行工具进行编译. 此命令能够生成: compile_commands.json
这个文件可以直接用于导入到clion进行调试.而不用生成CMakeList.txt文件
具体参考: 又是一个引用
