32bitBuilds - daudo/ojdkbuild GitHub Wiki

Goal

Building 32bit versions of ojdkbuild is simple.

Outline:

Prerequisites
Process - OpenJDK8
Process - OpenJDK9
Helper scripts

Prerequisites

development setup on Windows 2012 that allows to run one-off builds using run.bat launcher (see Win2012DevSetup)
for 32bit builds, all submodules need to be checked out recursively. If you haven't done so when initially checking out the project, do so now in a terminal emulator in the ojdkbuild root directory:
```
git submodule update --init
```

Process - OpenJDK8

In terminal emulator run the following to setup the appropriate development environment builds:
```
call "resources/scripts/set-compile-env-vs10-x86.bat"
```
Go to build directory and cleanup possible existing build artifacts:
```
cd build    
creset
```
Configure overall CMake project (that contains OpenJDK and dependencies) specifying the openjdk_32_BIT option:
```
cmake ../src/java-1.8.0-openjdk -Dopenjdk_32_BIT=ON -Dopenjdk_ENABLE_OPENJFX=ON -Dopenjdk_BOOTSTRAP_BUILD=ON 
```
If you don't want to include OpenJFX in your builds, you can omit the openjdk_ENABLE_OPENJFX option.
Run default nmake target to build all the dependencies (FreeType, NSS etc):
```
nmake
```
Run zip targets. This will build the project and produce compressed OpenJDK images:
```
nmake zip
nmake zip_jre
nmake openjfx_zip
```
If you haven't included the OpenJFX build flag in step 3, you can omit the nmake openjfx_zip line.
Once the last step has been successfully finished, you'll find the build results in the ojdkbuild/dist directory

Process - OpenJDK9

In terminal emulator run the following to setup the appropriate development environment builds:

for OpenJDK 9:
```
call "resources/scripts/set-compile-env-vs12-x86.bat"
```
Go to build directory and cleanup possible existing build artifacts:
```
cd build    
creset
```
Configure overall CMake project (that contains OpenJDK and dependencies) specifying the openjdk_32_BIT option:
```
cmake ../src/java-9-openjdk -Dopenjdk_32_BIT=ON -Dopenjdk_ENABLE_OPENJFX=ON -Dopenjdk_BOOTSTRAP_BUILD=ON
```
If you don't want to include OpenJFX in your builds, you can omit the openjdk_ENABLE_OPENJFX option.
Run default nmake target to build all the dependencies (FreeType, NSS etc):
```
nmake
```
Run zip targets. This will build the project and produce compressed OpenJDK images:
```
nmake zip
nmake zip_jre
nmake openjfx_zip
```
If you haven't included the OpenJFX build flag in step 3, you can omit the nmake openjfx_zip line.
Once the last step has been successfully finished, you'll find the build results in the ojdkbuild/dist directory

Helper scripts

Optionally, you can also use the following helper scripts in the ojdkbuild root directory to trigger 32bit builds:

OpenJDK 8:

@echo off

rem shortcuts from script directory
set BAD_SLASH_SCRIPT_DIR=%~dp0
set SCRIPT_DIR=%BAD_SLASH_SCRIPT_DIR:\=/%
set OJDKBUILD_DIR=%SCRIPT_DIR%

call "%OJDKBUILD_DIR%/resources/scripts/modules.bat"
if errorlevel 1 exit /b 1

call "%OJDKBUILD_DIR%/resources/profiles/jdk8_zip.gitmodules.txt"
if errorlevel 1 exit /b 1

call "%OJDKBUILD_DIR%/resources/scripts/set-compile-env-vs10-x86.bat"
@echo off
if errorlevel 1 exit /b 1

rmdir /s /q build
if exist build exit /b 1
mkdir build || exit /b 1
pushd build || exit /b 1

cmake "%OJDKBUILD_DIR%/src/java-1.8.0-openjdk" -Dopenjdk_ENABLE_OPENJFX=ON -Dopenjdk_32_BIT=ON -G "NMake Makefiles" || exit /b 1
nmake zip VERBOSE=1 || exit /b 1
nmake zip_jre VERBOSE=1 || exit /b 1
nmake openjfx_jre VERBOSE=1 || exit /b 1

popd || exit /b 1
echo OJDKBUILD32_FINISH_SUCCESS

OpenJDK 9

@echo off

rem shortcuts from script directory
set BAD_SLASH_SCRIPT_DIR=%~dp0
set SCRIPT_DIR=%BAD_SLASH_SCRIPT_DIR:\=/%
set OJDKBUILD_DIR=%SCRIPT_DIR%

call "%OJDKBUILD_DIR%/resources/scripts/modules.bat"
if errorlevel 1 exit /b 1

call "%OJDKBUILD_DIR%/resources/profiles/jdk9_zip.gitmodules.txt"
if errorlevel 1 exit /b 1

call "%OJDKBUILD_DIR%/resources/scripts/set-compile-env-vs12-x86.bat"
@echo off
if errorlevel 1 exit /b 1

rmdir /s /q build
if exist build exit /b 1
mkdir build || exit /b 1
pushd build || exit /b 1

cmake "%OJDKBUILD_DIR%/src/java-9-openjdk" -Dopenjdk_ENABLE_OPENJFX=ON -Dopenjdk_32_BIT=ON -G "NMake Makefiles" || exit /b 1
nmake zip VERBOSE=1 || exit /b 1
nmake zip_jre VERBOSE=1 || exit /b 1
nmake openjfx_jre VERBOSE=1 || exit /b 1

popd || exit /b 1
echo OJDKBUILD32_FINISH_SUCCESS
