 __Introduction__________________________________________________________________

 This readme file should provide all the information needed to build

 the HotSpot VM for Windows 95/Windows NT from its teamware workspace.

 It is intended as a starting point for people who want to learn how

 to work with the current HotSpot source workspace and who need to

 build the VM locally. It is not intended as a tutorial for licensees.

 Last update: 03/28/05

 __Platform______________________________________________________________________

 The VM builds under the following platforms:

 - Windows NT 4.0 on Intel x486 or greater

 - x486 PC (or greater), 32MByte or more

 __Tools_________________________________________________________________________

 For building/testing the following tools need to be available:

 - Microsoft Visual C++ 6.0 (with nmake version 1.62.7022 or greater)

 - MKS Toolkit 6.1 or greater

   see: /net/reinstall/export/vol0/pc-archive/software/mks6.1 (NFS)

    or: \\reinstall\pc-archive\software\mks6.1                (NT)

 __JDK___________________________________________________________________________

 The workspace works with the following version of the JDK:

 (NOTE: these are out of date)

 - JDK1.2FCS "V" build

   see: /usr/local/java/jdk1.2/win32

 and the following version(s) of HotJava:

 - hjb1.1.4

 - hjb1.1.5

   see /usr/local/java/hjb1.1.x/win32

 __Environment variables_________________________________________________________

 The following environment variables need to be set up for the IDE

 build process.  For batch builds these do not need to be set.

 HotSpotMksHome     points to the (NFS or PC-local) directory where the MKS

                    executables (like sh.exe and grep.exe) are installed

 Optionally you may set the following variables in your environment and they

 will be picked up by the create.bat script used to generate the vm.vcproj files.

 See the section on building within MS Developer Studio for more details.

 HotSpotWorkSpace   points to the (NFS) directory where the workspace is located

 HotSpotBuildSpace  points to the (PC-local) directory where the vm is built

 HotSpotReleaseBinDest points to the (NFS or PC-local) directory where the product DLL is

 		      written

 HotSpotDebugBinDest   points to the (NFS or PC-local) directory where the debug DLL is

 		      written

 NOTE: For both batch and IDE builds, java and javac must be in your

 PATH, and the versions found by default must work. (If this turns out

 to be a problem, we can define HotSpotJava and HotSpotJavaC for

 bootstrapping...)

 __Building the JVM from the command line________________________________________

 1) choose a directory in which you want to build the vm

    (the build process will create a subdirectory)

 2) To build the 'core' version (debug || optimized)

    %HotSpotWorkSpace%\build\windows\build <flavor> core %HotSpotWorkSpace% <jdk_dir>

    To build the 'compiler2' version (debug || optimized)

    %HotSpotWorkSpace%\build\windows\build <flavor> compiler2 %HotSpotWorkSpace% <jdk_dir>

    where <jdk_dir> is a full path to a JDK in which bin/java and

    bin/javac are present and working.

 3) If you have problems with building, first try:

    vcvars32 <CR> (sets path for VC++)

 4) In addition to jvm.dll, the Serviceability Agent (SA) based JDI connector 

    and command line tools are built if dbgeng.h and dbgeng.lib

    can be located, and BUILD_WIN_SA=1 is specified.   We look for dbgeng.h here:

         $(MSVCDIR)\PlatformSDK\Include

         $(SYSTEMROOT)\..\Program Files\Microsoft SDK\include

   The first directory is part of  Visual Studio VC .NET 2003.

   The second is used on Windows-amd64.

 __Building the JVM from within MS Developer Studio______________________________

 0) Set environment variables as described above

 1) Run the following script:

    %HotSpotWorkSpace%\build\windows\create <type> { <workspace> <buildspace> <productbindest> <debugbindest> }

    where type is one of core, compiler1, compiler2.  If you leave off the

    "<workspace> <buildspace> <productbindest> <debugbindest>" part, the script expects to find their

    values in the HotSpotWorkSpace, HotSpotBuildSpace, HotSpotReleaseBinDest, and HotSpotDebugBinDest environment

    variables.  The resulting vm.vcproj does not depend on these values in the environment.

    This will populate the build space with the appropriate makefiles

    and run nmake in it. This builds and runs makedeps, which now

    generates the appropriate vm.vcproj into the build space. It also

    builds and runs adlc.

    To regenerate the .incl and .dsp files after changing the include

    databases, just run nmake in the build space.

    The build process now relies on java and javac. For the IDE builds,

    the full path to a JDK (in which bin/java and bin/javac are present

    and working) can be specified either explicitly with the

    ALT_BOOTDIR environment variable (like the JDK build process), via

    the JDK build's default BOOTDIR environment variable, via JAVA_HOME,

    or implicitly via the PATH.

    (Note that there are now many more command line options to MakeDeps

    on the Windows platform than before. These have been bundled into

    makefiles/makedeps.make, but it is still necessary to keep this in

    sync with the batch makefiles, in vm/generated.)

    If you have problems with building (i.e,. finding nmake), first try:

    vcvars32 <CR> (sets path for VC++)

 2) Double-click the vm.vcproj file in the %HotSpotBuildSpace% directory

    to open MS Developer Studio.

 3) build desired or all versions:

    menu Build -> Batch Build... -> Build (or Rebuild All)

 4) jvm.dll is in the %HotSpotReleaseBinDest% or %HotSpotDebugBinDest% directory

    depending on which configuration you built (release or debug).

 Note: do not edit any of the files (especially the vm.vcproj file) in the

 build space, since they are all either autogenerated or copied from

 the work space. If necessary, modify the original Makefiles in

 %HotSpotWorkSpace%\build\windows\projectfiles, or the shared

 makedeps arguments in

 %HotSpotWorkSpace%\build\windows\makefiles\makedeps.make.

 Note that it appears that some options set in the IDE (for example,

 the default executable) show up not in the .dsp file, but in the .opt

 file, so the automatic regeneration of the .dsp file should not

 destroy the project settings. However, makedeps.make should be edited

 to supply per-file compiler options.

 To build adlc from within the IDE for debugging purposes:

 1) in MS Developer Studio, open ADLCompiler.dsw:

    menu File -> Open Workspace...

    select & double-click ADLCompiler.dsw

 2) rebuild all (debug mode is enough)

    menu Build -> Rebuild All (make sure Win32 Debug version is selected)

 __Testing the VM________________________________________________________________

 To test the VM using the Tonga Testsuite, use testlook. testlook is a very

 simple testing framework on top of Tonga which allows us to use one (Tonga)

 test file, that can be extended with attributes.

 1) copy %HotSpotWorkSpace%\test\testlook.bat onto PC (preferably

    %HotSpotBuildSpace%\bin, which should ideally be in the path)

 2) run testlook <cr> or testlook help <cr> for details

 3) to run testlook you need to have Tonga mounted:

    net use T: \\tapas\export1\psqe

 __HotJava under HotSpot_________________________________________________________

 To run HotJava, use the .bat file %HotSpotWorkSpace%\test\h.bat. Copy

 it into %HotSpotBuildSpace%/<flavor> (which ideally is in the path) and run

 HotJava: h java <flags> (e.g., h java_g -Xint).

 __Preferred directory setup under Windows NT____________________________________

 Within the HotSpot group we are using the following directory setup:

 D:\jdk1.2          - where we install the JDK

 The following drives are mounted for testing/putbacks/etc.:

 net use T: \\tapas\export1\psqe

 net use Y: \\rschmidt\GammaBase

 net use Z: \\animorphic\animorphic
