jdk编译
· 2 min read
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
