JDK7 build under windows

[John Francis]

I am trying to build openjdk7 b100 under Windows Server 2008 SP2. I am using cygwin 1.7+ I am having trouble with openjdk/langtools/make The Makefile there sets up some java support for Ant using the ALT_BOOTDIR, which therefore must be a valid cygwin path, such as /cygdrive/c/DEVELO~1/JDK/bootJDK/JDK16~1.0_1 However if set to a cygwin style path, the ant build.xml in openjdk/langtools/make fails because it uses the available task to test the correctness of the boot.java.home property ( set from the same Makefile which had to have the cygwin path ). As you doubtless know ( http://ant.apache.org/manual/platform.html ) when ant is executed by cygwin it still expects Windows path names. I could doubtless hack the build.properties or Makefile to set the boot.java.home to a windows path, but I am concerned that I am doing something else wrong which I will have to fix again and again. What format should ALT_BOOTDIR have when running cygwin? Windows or cygwin? Is there some property file I can edit to satisfy all the build? Here is the output of an edited build.xml when I set ALT_BOOTDIR to a cygwin path ( see below for the redefined macro, check... <target name="-def-check"> <macrodef name="check"> <attribute name="name"/> <attribute name="property"/> <attribute name="marker" default=""/> <sequential> <echo message="-def-check @@{name} is '@{name}'" /> <echo message="-def-check @@{property} is '@{property}'" /> <echo message="-def-check @@{marker} is '@{marker}'" /> <echo message="-def-check $${@@{property}} is '$...@{property}}'" /> <echo message="-def-check $${@@{property}}/@@{marker} is '$...@{property}}/@{marker}'" /> <available property="foo" file="$...@{property}}/@{marker}" value="available" /> <echo message="-def-check $${@@{property}}/@@{marker} is ${foo}" /> <available property="foo2" file="C:\development\JDK\bootJDK\jdk1.6.0_18/bin/java.exe" value="available" /> <echo message="-def-check a proper windows path is ${foo2}" /> …. outputs; -check-boot.java.home: [echo] -def-check @{name} is 'bootstrap java' [echo] -def-check @{property} is 'boot.java.home' [echo] -def-check @{marker} is 'bin/java.exe' [echo] -def-check $...@{property}} is '/cygdrive/c/DEVELO~1/JDK/bootJDK/JDK16~1.0_1' [echo] -def-check $...@{property}}/@{marker} is '/cygdrive/c/DEVELO~1/JDK/bootJDK/JDK16~1.0_1/bin/java.exe' [echo] -def-check $...@{property}}/@{marker} is ${foo} [echo] -def-check a proper windows path is available here is my cygwin.bat @echo off @echo Remember old LIB INCLUDE and PATH, in case needed and set to WIN_ORIG_XXX. set WIN_ORIG_INCLUDE=%INCLUDE% set WIN_ORIG_LIB=%LIB% set WIN_ORIG_PATH=%PATH% @echo Clear LIB, PATH, INCLUDE ** and ** CLASSPATH set INCLUDE= set LIB= set PATH= set CLASSPATH= rem setup INCLUDE, LIB, PATH for M$ VC call "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86 @echo Set up special VC_PATH variable to be picked up in .bashrc and placed on the path before cygwin. set VC_PATH=%PATH% @echo Clear Path to nothing ... just take what cygwin provides, do not edit /etc/profile which is edited only by cygwin. set PATH= rem setup ALT_XXX vars for OpenJDK set ALT_BOOTDIR=C:\development\JDK\bootJDK\jdk1.6.0_18 set ALT_BINARY_PLUGS_PATH=C:\development\JDK\openjdk7-b100\openjdk-binary-plugs set ANT_HOME=C:\development\apache-ant-1.8.1 rem allow openjdk to find this for itself rem set ALT_MSVCRT_DLL_PATH=C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86\Microsoft.VC90.CRT\msvcr90.dll set ALT_FREETYPE_HEADERS_PATH=C:/development/GnuWin32/include set ALT_FREETYPE_LIB_PATH=C:/development/GnuWin32/lib rem This is one of my own set ALT_MT_PATH=C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin rem DSDK should already be on the path @echo on set CYGWIN=upcaseenv @echo off C: chdir C:\cygwin\bin bash --login -i here is my .bashrc; # User dependent .bashrc file # Environment Variables # ##################### # TMP and TEMP are defined in the Windows environment.
