OpenJDK 编译问题

1. 操作系统建议 Ubuntu 16

直接使用 VMware 安装 Ubuntu 16 编译

ubuntu1604 使用 Clion 调试 openjdk8 - 知乎

‍

configure

bash configure --with-target-bits=64 --with-boot-jdk=/home/jcb/jdk1.7.0_80 --with-debug-level=slowdebug --enable-debug-symbols ZIP_DEBUGINFO_FILES=0 --with-extra-cxxflags="-Wno-error" --with-extra-cflags="-Wno-error"

‍

2. 各种依赖的问题

Could not find X11 libraries

configure: error: Could not find X11 libraries. You might be able to fix this by running 'sudo apt-get install libX11-dev libxext-dev libxrender-dev libxtst-dev libxt-dev'.

‍

这里可能需要将 libX11-dev 修改为 libx11-dev【小写】

‍

configure: error: Could not find alsa! You might be able to fix this by running 'sudo apt-get install libasound2-dev'. 

‍

sudo apt-get install libx11-dev libxext-dev libxrender-dev libxtst-dev libxt-dev -y
sudo apt-get install libcups2-dev -y
sudo apt-get install libfreetype6-dev -y
sudo apt-get install libasound2-dev -y
sudo apt-get install ccache -y

freetype 问题

linux - Compile JDK8 error.''Could not find freetype'' - Stack Overflow

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

解决办法：

方法一：更换 make 为 4.0 版本以下（未测试）方法二：修改 hotspot/make/linux/makefiles/adjust-mflags.sh

约第 67 行增加一个 I，修改

问题原因：

make 版本的问题，4.0 以后 make-I 和-j 选项混乱，具体看参考资料
