New build system of openJDK (jdk8 master forest) rocks!

Just tried with new build system in OpenJDK (jdk8 master forest) on Windows, now there is no pain as it was with the old build. Just start the build and relax....

If any one interested to try out just check this link "http://openjdk.java.net/projects/build-infra/guide.html"

PS: if you end up with "Defs-utils.gmk: No such file or directory", just go and create a dummy file named "Defs-utils.gmk" in "jdk/makefiles/common/shared"

Building OpenJDK 7 (openjdk-7-ea-src-b105-13_aug_2010) On Windows [Service Pack 3, Version 5.1]

Building OpenJDK 7 (openjdk-7-ea-src-b105-13_aug_2010) On Windows [Service Pack 3, Version 5.1]


Source used: openjdk-7-ea-src-b105-13_aug_2010
Local Path Source: Windows path "E:\dev\jdk7\openjdk-7-ea-src-b105-13_aug_2010" and cygwin path "/cygdrive/e/dev/jdk7/openjdk-7-ea-src-b105-13_aug_2010"
Boot strap JDK: jdk1.6.0_18
Installed the Binary Plugs: downloaded it from "http://www.java.net/download/openjdk/jdk7/promoted/b92/jdk-7-ea-plug-b92-windows-i586-06_may_2010.jar"

Basic environment variables
# Boot strap JDK, windows path "D:\Java\jdk1.6.0_18"
export ALT_BOOTDIR=D:/JAVA/JDK16~1.0_1
# Binary Plugin
export ALT_BINARY_PLUGS_PATH=E:/DEV/JDK7/JDK7EA~2/OPENJD~1

# Set OPENJDK to true
export OPENJDK=true

Task 1: Run "make sanity" with out errors
------------------------------------------------
Started cygwin and exported all the ALT_ variables above and ran the sanity by "make sanity".
The first sanity make ended in below error "ERROR: FreeType version 2.3.0 or higher is required.", I tried to installed freetype for cygwin, and re-ran the sanity, but ended up with same error.

Searched and found an direction from the link belwo which says "It's trying to build a freetype check program with VS2010, and probably found a stdio.h from the CYGWIN /usr/include, not the stdio.h you want.........which means downloading freetype sources and building it, and saving those files. Yes, I know, painful. Sorry in advance.".
That means I needed to download freeType and build it localy.

http://markmail.org/thread/g6zrjtpmo4sda7aw#query:freetypecheck.c%2829%29%20%3A%20fatal%20error%20C1083%3A%20Cannot%20open%20include%20file%3A%20%27stdio.h%27%3A%20No%20such%20file%20or%20directory+page:1+mid:4bd7hun3tmbwmjql+state:results

So downloaded FreeType version 2.4.4 (freetype-2.4.4) and tried to build using make in cygwin, but ended up with below error
make: ver: Command not found
make: type: Command not found
make: *** [dos_setup] Error 127
Couldn't find a solution (tried a lot to search on web), then using "VC++ 2010 Exp" I build the freetype as explained below

1. Double clicked the file "freetype-2.4.4\builds\win32\visualc\freetype.dsp"
2. Clicked next in "Conversion wizard", if needed choose backup before convertion, and click next and finish.
3. In "Solution Explorer", right clicked and choosen "Configuration Properties"->"General" in left panel, and in the right panel changed "Configuration Type" to "Dynamic Library (.dll)"
4. And made a build (F7), this will create freetype.dll in "freetype-2.4.4\objs\debug".

freetype.lib too is need for the build, we could use VC 2010 for this, but I couldn't genereated the lib file, instead I build freetype.lib using "ftjam-2.5.2-win32"
1. download, extact and set ftjam's bin in path.
2. Open "Visual Studio Command Prompt 2010" found in start up menu.
3. Changed directory to the root of the freetype-2.4.4, and type jam.
4. freetype.lib is created in "freetype-2.4.4\objs"

Copy this freetype.dll and freetype.lib in a directory, in my case I created "lib" directory in "E:\dev\jdk7\freetype-2.4.4_V2\freetype-2.4.4\lib" folder.

Now export the ALT_FREETYPE_LIB_PATH in cygwin environment
export ALT_FREETYPE_LIB_PATH=E:/DEV/JDK7/FREETY~2.4_V/FREETY~1.4/LIB

Note: To get the path as above "E:/DEV/JDK7/FREETY~2.4_V/FREETY~1.4/LIB", the simple solution is, first using cmd go to the path, in my case I typed
"cd cd E:\dev\jdk7\freetype-2.4.4_V2\freetype-2.4.4\lib" and then type "command" we get "E:\DEV\JDK7\FREETY~2.4_V\FREETY~1.4\LIB", now replace '\' with '/' and we get the path.

Now set the ALT_FREETYPE_HEADERS_PATH
export ALT_FREETYPE_HEADERS_PATH=E:/DEV/JDK7/FREETY~2.4_V/FREETY~1.4/INCLUDE

Here I was able to successfully run the sanity check.


Task 2: Building OpenJdk
------------------------------------------------
After sucessfull sanity check, we can go ahead and build the system. Just type make, and I ended with below error

D:/PROGRA~1/MICROS~1.0/VC/Bin/rc: No such file or directory

RC.exe is no more available in VC++ 2010, instead its available in Microsoft SDK, my system contains Microsoft SDK at location "C:\Program Files\Microsoft SDKs"
Now export variable MSSDKTOOLS_PATH as below which should point to BIN directory of Microsoft SDK

export MSSDKTOOLS_PATH=C:/PROGRA~1/MI2578~1/WINDOWS/V7.0A/BIN

And change the content of the file Compiler-msvc.gmk as below located at "openjdk-7-ea-src-b105-13_aug_2010\jdk\make\common\shared"

"RC = $(MSDEVTOOLS_PATH)rc" to "RC = $(MSSDKTOOLS_PATH)rc"
"RSC = $(MSDEVTOOLS_PATH)rc" to "RSC = $(MSSDKTOOLS_PATH)rc"

its enough to change MTL and MT for only VC 10, ie in the if block of COMPILER_NAME as Visual Studio 10
"MTL = $(MSDEVTOOLS_PATH)/midl.exe" to "MTL = $(MSSDKTOOLS_PATH)/midl.exe"
"MT = $(MSDEVTOOLS_PATH)mt" to "MT = $(MSSDKTOOLS_PATH)mt"

Here basically we are pointing RC, midl and mt to be picked from microsoft sdk rather from Visual Studio 10

That should build OpenJDK.
