MacOS 10.15编译openjdk8u详细过程
MacOS 10.15编译openjdk8u详细过程
三年前编译过一次openjdk8，最近需要调试，发现当时编译时没加调试信息，于是准备重新编译，由于机器信息与三年前完全不同，编译时的异常超出我预期，经过一周折腾终于编译通过，以下上本次编译的详细过程，希望对大家避坑有帮助
环境
1. 机器环境信息
JVM输出系统信息
OS:Bsduname:Darwin 19.4.0 Darwin Kernel Version 19.4.0: Wed Mar 4 22:28:40 PST 2020; root:xnu-6153.101.6~15/RELEASE_X86_64 x86_64
rlimit: STACK 8192k, CORE 0k, NPROC 2784, NOFILE 10240, AS infinity
CPU:total 4 (initial active 4) (2 cores per cpu, 2 threads per core) family 6 model 78 stepping 3, cmov, cx8, fxsr, mmx, sse, sse2, sse3, ssse3, sse4.1, sse4.2, popcnt, avx, avx2, aes, clmul, erms, rtm, 3dnowpref, lzcnt, ht, tsc, tscinvbit, bmi1, bmi2, adx
Memory: 4k page, physical 16777216k(369628k free)
2.依赖软件安装
-
Boot-strap JDK : jdk-7u80-macosx-x64.dmg
-
XQuartz : XQuartz-2.7.11.dmg
-
brew 安装以下软件
brew install freetype brew install ant brew install ccache brew install autoconf brew install llvm brew install binutils -
期间为了解决问题安装过[email protected]和gcc@7没有使用到
准备
1. mercurial安装
lizhengdeMacBook-Pro:homebrew-core lizheng$ brew install mercurial
2. 代码下载
直接从源码库克隆源码，然后使用命令下载代码
hg clone http://hg.openjdk.java.net/jdk8u/jdk8u jdk8u
hg pull
vim batchget.sh
chmod +x batchget.sh
./batchget.sh
如果网速不好可以参考网上另一篇文篇，使用批量脚本（batchget.sh），脚本如下
#!/bin/bash
for i in {1..28}
do
sh ./get_source.sh;
done
3. 查看configure帮助
lizhengdeMacBook-Pro:openjdk8 lizheng$ bash configure --help
Running generated-configure.sh
4.安装配置
./configure --with-xcode-path --with-debug-level=slowdebug --with-boot-jdk=`/usr/libexec/java_home -v 1.7` --enable-debug-symbols --disable-zip-debug-info --with-memory-size=6144 ZIP_DEBUGINFO_FILES=0 OBJCOPY=gobjcopy --with-jobs=8 CC=clang CXX=clang++ --with-native-debug-symbols=internal
configure有不少的参数, 具体的参数可以通过 'bash ./configure --help' 查看
--with-debug-level=slowdebug 表示构建debug版本, openjdk8去掉了jvmg版本的构建
--enable-debug-symbols 和 ZIP_DEBUGINFO_FILES=0 主要是方便调试
运行输出:
lizhengdeMacBook-Pro:jdk8uuu lizheng$ ./configure --with-xcode-path --with-debug-level=slowdebug --with-boot-jdk=`/usr/libexec/java_home -v 1.7` --enable-debug-symbols --disable-zip-debug-info --with-memory-size=6144 ZIP_DEBUGINFO_FILES=0 OBJCOPY=gobjcopy --with-jobs=8 CC=clang CXX=clang++ --with-native-debug-symbols=internal

==> Pouring binutils-2.34.catalina.bottle.tar.gz
==> Caveats
binutils is keg-only, which means it was not symlinked into /usr/local,
because Apple's CLT provides the same tools.
If you need to have binutils first in your PATH run:
echo 'export PATH="/usr/local/opt/binutils/bin:$PATH"' >> ~/.bash_profile
For compilers to find binutils you may need to set:
export LDFLAGS="-L/usr/local/opt/binutils/lib"
export CPPFLAGS="-I/usr/local/opt/binutils/include"

Build performance summary:

Build performance tip: ccache gives a tremendous speedup for C++ recompilations.
You have ccache installed, but it is a version prior to 3.1.4. Try upgrading.

1. 第一个必须说的异常，目前还没在网上发现答案adlc.hpp:36:10: fatal error: 'iostream' file not found

#include 这个问题原因是因为Xcode 10以后删除了libstdc++库，转而使用libc++，我做过很多尝试都没办法解决，可以参考这篇文章
=====以下是无效尝试
第一个就是按报错提示，在编译的时候加上
-stdlib=libc++，用这个方法出现一堆日志根本没办法看，而且编译不通过使用stackover方法用
#include "/Library/Developer/CommandLineTools/usr/include/c++/v1/iostream"替换#include，这个会报一个下载安装Xcode_9.4.1.xip，安装后
Xcode-select --switch切换路径，报错promote:jdk8uu lizheng$ sudo xcode-select -s /Applications/Xcode9.4.1/Xcode.app/Contents/Developer/ Password: promote:jdk8uu lizheng$ xcode-select -p /Applications/Xcode9.4.1/Xcode.app/Contents/Developer promote:jdk8uu lizheng$ make all JOBS=8 ZIP_DEBUGINFO_FILES=0 COMPILER_WARNINGS_FATAL=false CC=clang USE_CLANG=true LP64=1 dyld: Symbol not found: _OBJC_IVAR_$_NSFont._fFlags Referenced from: /Applications/Xcode9.4.1/Xcode.app/Contents/SharedFrameworks/DVTDocumentation.framework/Versions/A/../../../../SharedFrameworks/DVTKit.framework/Versions/A/DVTKit Expected in: /System/Library/Frameworks/AppKit.framework/Versions/C/AppKit in /Applications/Xcode9.4.1/Xcode.app/Contents/SharedFrameworks/DVTDocumentation.framework/Versions/A/../../../../SharedFrameworks/DVTKit.framework/Versions/A/DVTKit make: error: unable to locate xcodebuild, please make sure the path to the Xcode folder is set correctly! make: error: You can set the path to the Xcode folder using /usr/bin/xcode-select -switch=======以下是成功方法=
最后使用的办法是从github上下载库，然后设置环境变量后解决，此方法我编译过两次都通过
git clone https://github.com/imkiwa/xcode-missing-libstdc-.git执行install.sh，脚本如下
#!/usr/bin/env bash set -e sudo ln -s \ $PWD/include/c++ \ /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/ sudo ln -s \ $PWD/lib/libstdc++.6.0.9.tbd \ $PWD/lib/libstdc++.6.tbd \ $PWD/lib/libstdc++.tbd \ /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/做完以上两步还是报同样的错，需要设置环境变量，可以参考这篇文章
export CFLAGS="-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1" export CXXFLAGS="-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1" export LDFLAGS=-L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/完成以上设置还会报错
ld: library not found for -lstdc++，可以参考这篇文章，解决办法如下：export LIBRARY_PATH=$LIBRARY_PATH:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/
2. 报错error: invalid argument '-std=gnu++98' not allowed with 'C' make[6]: *** [libjsig.dylib] Error 1，解决办法参考https://www.cnblogs.com/zhengshuangxi/p/11063938.html
