标签：编译openjdk
学习《深入了解java虚拟机》，按照书上的步骤试着自己编译了个jdk，耗时大半个下午，中间遇到不少问题，在这记录下。
一、环境说明
linux 版本
[root@localhost openjdk_compile]# lsb_release -a LSB Version::base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch Distributor ID:CentOS Description:CentOS release 6.9 (Final) Release:6.9 Codename:Final
openjdk版本
openjdk-7u75-src-b13-18_dec_2014.zip
二、构建编译环境
安装必要工具包
[root@localhost openjdk_compile]# yum groupinstall "Development Tools"
[root@localhost openjdk_compile]# yum install ant
设置环境变量
unset JAVA_HOME unset CLASSPATH export LANG=C export ALT_BOOTDIR=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141-1.b16.el7_3.x86_64 #允许自动下载依赖 export ALLOW_DOWNLOADS=true #并行编译的线程数，设置为和cpu内核数量一致即可 export HOTSPOT_BUILD_JOBS=2 export ALT_PARALLEL_COMPIL_JOBS=2 #比较本次build出来的映像与先前版本的差异。这对我们来说没有意义 #必须设置为false，否则sanity检查会报缺少先前版本的JDK的映像的错误提示。 #如果已经设置dev或者DEV_ONLY=true,这个不显示设置也行 export SKIP_COMPARE_IMAGES=true #使用预编译头文件，不加这个编译会更慢一些 export USE_PRECOMPILED_HEADER=true #要编译的内容 export BUILD_LANGTOOLS=true #export BUILD_JAXP=false #export BUILD_JAXWS=false #export BUILD_CORBA=false export BUILD_HOTSPOT=true export BUILD_JDK=true #要编译的版本 #export SKIP_DEBUG_BUILD=false #export SKIP_FASTDEBUG_BUILD=true #export DEBUG_NAME=debug #把它设置为false，可以避开javaws和浏览器java插件之类的部分的build export BUILD_DEPLOY=false #把它设置为false就不会build出安装包。因为安装包有些奇怪的依赖 #但即便不build出安装包也能得到完整的JDK映像，所以还是别build好了 export BUILD_INSTALL=false #编译结果存放的路劲 export ALT_OUTPUTDIR=/root/openjdk_compile/build
切换到源代码根路径，执行make sanity，得到结果：
WARNING: LANG has been set to zh_CN.UTF-8, this can cause build failures. Try setting LANG to ‘C‘. ERROR: Your CLASSPATH environment variable is set. This will most likely cause the build to fail. Please unset it and start your build again. ERROR: Your JAVA_HOME environment variable is set. This will most likely cause the build to fail. Please unset it and start your build again. ERROR: You seem to not have installed ALSA 0.9.1 or higher. Please install ALSA (drivers and lib). You can download the source distribution from http://www.alsa-project.org or go to http://www.freshrpms.net/docs/alsa/ for precompiled RPM packages. ERROR: FreeType version 2.3.0 or higher is required. make[2]: 进入目录“/root/openjdk_compile/openjdk/jdk/make/tools/freetypecheck” /bin/mkdir -p /root/openjdk_compile/openjdk/build/linux-amd64/btbins rm -f /root/openjdk_compile/openjdk/build/linux-amd64/btbins/freetype_versioncheck make[2]: 离开目录“/root/openjdk_compile/openjdk/jdk/make/tools/freetypecheck” Failed to build freetypecheck. ERROR: You do not have access to valid Cups header files. Please check your access to /usr/include/cups/cups.h and/or check your value of ALT_CUPS_HEADERS_PATH, CUPS is frequently pre-installed on many systems, or may be downloaded from http://www.cups.org Exiting because of the above error(s). make: *** [post-sanity] 错误 1
分析：
1.设置环境变量方式有误： 永久环境变量（属于文件，比如profile以及home目录下的），临时环境变量（当前shell以及子线程），普通环境变量（当前shell）
解决：在当前shell执行相关export
2. FreeType 没有安装
解决：yum install freetype-devel
3. ALSA 没有安装（声卡 应该没什么关系）
解决：sudo yum install alsa*
4：You do not have access to valid Cups header files.
解决：sudo yum install cups-devel.x86_64
二、开始编译
执行命令：
make 2>&1 | tee $ALT_OUTPUTDIR/build.log
记录下错误
错误1：

/root/openjdk_compile/openjdk/langtools/make/build.xml:795: Compile failed; see the compiler error output for details.解决方法：Bootstrap jdk版本换成jdk1.7
错误2：

解决方案：sudo yum install libstdc++-static.x86_64

解决方案：修改/jdk/src/share/classes/java/util/CurrencyData.properties文件,将其中10年以前的时间都设置到10年以内
