jdk编译

Posted on:September 20, 2022 at 07:42 AM

第一步

拉取代码

git clone https://github.com/openjdk/jdk.git

第二步

本地版本：

我本地的jdk版本是17

java -version
openjdk version "17.0.4" 2022-07-19

jdk 只能由上一个版本自举，所以必须要切到下一个大版本 ，我本地是jdk17 ，所以要切到jdk 18

## 切换到jdk18
git checkout jdk-18+37

## 生成makefile 

./configure --with-debug-level=slowdebug  --with-extra-cflags="-Wno-nonnull -Wno-maybe-uninitialized -Wno-free-nonheap-object"
## 2个线程同时编译

make JOBS=2  CONF=linux-x86_64-server-slowdebug
