Mac系统安装

利用brew search查找mercurial ➜ ~ brew search mercurial 安装 ➜ ~ brew install mercuria

Linux系统安装

sudo apt install mercurial

安装openjdk8

添加代理

一般在下载代码的时候都会很慢，故先配置好代理。我这里是V2Ray。

vim /usr/local/etc/mercurial/hgrc
[http_proxy]
host=127.0.0.1:8001
[https_proxy]
host=127.0.0.1:8001

下载jdk8u的代码

hg clone https://hg.openjdk.java.net/jdk8u/jdk8u openjdk8 chmod u+x get_source.sh chmod u+x configure ./get_source.sh # 下载全部源代码 ./configure --with-freetype-include=/usr/local/include/freetype2 --with-freetype-lib=/usr/local/lib/ # configure 编译环境，若编译报错，需要添加 `--disable-warnings-as-errors` make all

漫长的等待，终于等到你

如何在CLion里面做调试，后面我再详细的写一篇。敬请期待~

遇到的坑

问题一：Xcode 4 is required to build JDK 8

configure: error: Xcode 4 is required to build JDK 8, the version found was 11.4.1. Use --with-xcode-path to specify the location of Xcode 4 or make Xcode 4 active by using xcode-select. configure exiting with result code 1

解决方案：

➜  openjdk8  vim common/autoconf/generated-configure.sh
# Fail-fast: verify we"re building on Xcode 4, we cannot build with Xcode 5 or later
#XCODE_VERSION=`$XCODEBUILD -version | grep "^Xcode " | sed "s/Xcode //"`
#XC_VERSION_PARTS=( ${XCODE_VERSION//./ } )
#if test ! "${XC_VERSION_PARTS[0]}" = "4"; then
#  as_fn_error $? "Xcode 4 is required to build JDK 8, the version found was $XCODE_VERSION. Use --with-xcode-path to specify the l      ocation of Xcode 4 or make Xcode 4 active by using xcode-select." "$LINENO" 5
#fi

问题二：A gcc compiler is required

configure: error: A gcc compiler is required. Try setting --with-tools-dir. configure exiting with result code # 第一处代码 elif test "x$TOOLCHAIN_TYPE" = xgcc; then # gcc --version output typically looks like # gcc (Ubuntu/Linaro 4.8.1-10ubuntu9) 4.8.1 # Copyright (C) 2013 Free Software Foundation, Inc. # This is free software; see the source for copying conditions.

COMPILER_VERSION_OUTPUT=`$COMPILER --version 2>&1` # Check that this is likely to be GCC. $ECHO "$COMPILER_VERSION_OUTPUT" | $GREP "Free Software Foundation" > /dev/null # 条件语句注释掉 # if test $? -ne 0; then # { $as_echo "$as_me:${as_lineno-$LINENO}: The $COMPILER_NAME compiler (located as $COMPILER) does not seem to be the required $TOOLCHAIN_TYPE compiler." >&5 # $as_echo "$as_me: The $COMPILER_NAME compiler (located as $COMPILER) does not seem to be the required $TOOLCHAIN_TYPE compiler." >&6;} # { $as_echo "$as_me:${as_lineno-$LINENO}: The result from running with --version was: "$COMPILER_VERSION"" >&5 # $as_echo "$as_me: The result from running with --version was: "$COMPILER_VERSION"" >&6;} # as_fn_error $? "A $TOOLCHAIN_TYPE compiler is required. Try setting --with-tools-dir." "$LINENO" 5 # fi # 第二处代码， elif test "x$TOOLCHAIN_TYPE" = xgcc; then # gcc --version output typically looks like # gcc (Ubuntu/Linaro 4.8.1-10ubuntu9) 4.8.1 # Copyright (C) 2013 Free Software Foundation, Inc. # This is free software; see the source for copying conditions.

"A $TOOLCHAIN_TYPE compiler is required. Try setting --with-tools-dir." "$LINENO" 5

最后执行sh configure终于成功：

问题三：include path for libstdc++ headers not found

clang: clangerror: include path for libstdc++ headers not found; pass "-stdlib=libc++" on the command line to use the libc++ standard library instead [-Werror,-Wstdlibcxx-not-found]

make: *** [hotspot-only] Error 2

解决方法

原因：这个原因是Xcode升级到10以后就没有包含lstdc++库了。而 hotspot 居然还一直用着这个，于是编译器找不到 libstdc++ 的头文件就罢工了

解决办法：

打开:https://github.com/imkiwa/xcode-missing-libstdc- , clone 到本地，参考 install.sh 将文件链接或者复制到对应位置（慎重直接执行，请一定事先核对路径是否正确)！

问题四：fatal error: "iostream" file not found

解决方案

xcode-select --install

问题五：unknown argument: "-fpch-deps"
