深夜裏安靜的編譯一個OpenJDK8，坑太多

Mac系統安裝

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

Linux系統安裝

sudo apt install mercurial

安裝openjdk8

添加代理

一般在下載代碼的時候都會很慢，故先配置好代理。我這裏是V2Ray。

vim /usr/local/etc/mercurial/hgrc

[http_proxy]
host=127.0.0.1:8001
[https_proxy]
host=127.0.0.1:8001

下載jdk8u的代碼

hg clone https://hg.openjdk.java.net/jdk8u/jdk8u openjdk8
chmod u+x get_source.sh
chmod u+x configure
./get_source.sh  # 下載全部源代碼  
./configure  --with-freetype-include=/usr/local/include/freetype2 --with-freetype-lib=/usr/local/lib/      # configure 編譯環境，若編譯報錯，需要添加 `--disable-warnings-as-errors`
make all

遇到的坑

問題一：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

解決方案：

➜  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

問題二：A gcc compiler is required

configure: error: A gcc compiler is required. Try setting --with-tools-dir.
configure exiting with result code

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

最後執行sh configure終於成功：

using default settings.

問題三：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]
: error: 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

解決方法

原因：這個原因是Xcode升級到10以後就沒有包含lstdc++庫了。而 hotspot 居然還一直用着這個，於是編譯器找不到 libstdc++ 的頭文件就罷工了解決辦法：打開:https://github.com/imkiwa/xcode-missing-libstdc- , clone 到本地，參考 install.sh 將文件鏈接或者複製到對應位置（慎重直接執行，請一定事先覈對路徑是否正確)！

問題四：fatal error: 'iostream' file not found

/Users/chenyuan/Workspaces/Openjdk/openjdk8/hotspot/src/share/vm/adlc/archDesc.cpp:#include <iostream>/Users/chenyuan/Workspaces/Openjdk/openjdk8/hotspot/src/share/vm/adlc/adlc.hpp

1 error generated.
make[6]: *** [../generated/adfiles/arena.o] Error 1
make[6]: *** Waiting for unfinished jobs....

解決方案

xcode-select --install

問題五：unknown argument: '-fpch-deps'

解決方案：

hotspot/make/bsd/makefiles/gcc.make

# Compiler warnings are treated as errors
ifneq ($(COMPILER_WARNINGS_FATAL),false)
  WARNINGS_ARE_ERRORS = -Werror
endif

這一段也要幹掉，否則在後續編譯中可能會出現clang: error: unknown argument: '-fpch-deps'

ifeq ($(USE_CLANG),)
  ifneq ($(CC_VER_MAJOR), 2)
    DEPFLAGS += -fpch-deps
  endif
endif

問題六：invalid argument ‘-std=gnu++98’ not allowed with ‘C’

Making signal interposition lib...
error: invalid argument '-std=gnu++98' not allowed with 'C'
make[6]: *** [libjsig.dylib] Error 1

解決方案

if test "x$TOOLCHAIN_TYPE" = xsolstudio; then
    if test "x$OPENJDK_TARGET_CPU_ARCH" = "xsparc"; then
      CFLAGS_JDKLIB_EXTRA="${CFLAGS_JDKLIB_EXTRA} -xregs=no%appl"
      CXXFLAGS_JDKLIB_EXTRA="${CXXFLAGS_JDKLIB_EXTRA} -xregs=no%appl"
    fi
  elif test "x$TOOLCHAIN_TYPE" = xxlc; then
    LDFLAGS_JDK="${LDFLAGS_JDK} -q64 -brtl -bnolibpath -liconv -bexpall"
    CFLAGS_JDK="${CFLAGS_JDK} -qchars=signed -q64 -qfullpath -qsaveopt"
    CXXFLAGS_JDK="${CXXFLAGS_JDK} -qchars=signed -q64 -qfullpath -qsaveopt"
  elif test "x$TOOLCHAIN_TYPE" = xgcc; then
    LEGACY_EXTRA_CFLAGS="$LEGACY_EXTRA_CFLAGS -fstack-protector"
    LEGACY_EXTRA_CXXFLAGS="$LEGACY_EXTRA_CXXFLAGS -fstack-protector"
    if test "x$OPENJDK_TARGET_OS" != xmacosx; then
      LDFLAGS_JDK="$LDFLAGS_JDK -Wl,-z,relro"
      LEGACY_EXTRA_LDFLAGS="$LEGACY_EXTRA_LDFLAGS -Wl,-z,relro"
    fi
#    CXXSTD_CXXFLAG="-std=gnu++98" # 註釋掉這行
