JetBrains Runtime

JetBrains Runtime is a runtime environment for running IntelliJ Platform-based products on Windows, macOS, and Linux. It is based on the OpenJDK project, with some modifications, including:

• Subpixel anti-aliasing
• Enhanced font rendering on Linux
• HiDPI support
• Ligatures
• Some fixes for native crashes not presented in official build
• Other small enhancements

JetBrains Runtime is not a certified build of OpenJDK. Please, use at your own risk.

Usually, we do not modify any of the repositories except jdk module. Other repositories are needed for build purposes.

Getting sources

OSX, Linux:

git config --global core.autocrlf input
git clone [email protected]:JetBrains/jdk8u.git
cd jdk8u
./getModules.sh

Windows:

git config --global core.autocrlf false
git clone [email protected]:JetBrains/jdk8u.git
cd jdk8u
getModules.bat

Configure Local Build Environment

Linux

sudo apt-get install git zip bzip2 unzip tar curl
sudo apt-get install ccache make gcc g++ ca-certificates ca-certificates-java
sudo apt-get install libxext-dev libxrender-dev libxtst-dev libxt-dev
sudo apt-get install libasound2-dev libcups2-dev libfreetype6-dev
git clone [email protected]:JetBrains/jdk8u.git
cd jdk8u
./getModules.sh
download jdk8 from Oracle into /home/user/jdk1.8.0_102
export JAVA_HOME=/home/user/jdk1.8.0_102
sh ./configure
make

Windows

Install:

• Cygwin x64 Required packages (binutils, cpio, diffutils, file, gawk, gcc-core, make, m4, unzip, zip)
• Windows SDK 7.1 offline installer GRMSDKX_EN_DVD.iso Run Setup\SDKSetup
• Visual Studio Express 2010 offline installer VS2010Express1.iso
  • Virtual CloneDrive may help to mount ISO images
• DirectX 9.0 SDK
• Java 8

Build Freetype:

• Download sources
• Execute the following script in builds\windows\vc2010

(echo ^<?xml version="1.0" encoding="utf-8"?^>
echo ^<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"^>
echo ^<PropertyGroup Label="Globals"^>
echo ^<TargetName^>freetype^</TargetName^>
echo ^<UserIncludeDirectories^>.^</UserIncludeDirectories^>
echo ^</PropertyGroup^>
echo ^<ItemDefinitionGroup^>
echo ^<ClCompile^>
echo ^<ForcedIncludeFiles^>jb_custom.h^</ForcedIncludeFiles^>
echo ^</ClCompile^>
echo ^</ItemDefinitionGroup^>
echo ^</Project^>) > freetype.user.props
(echo #ifndef __JB_CUSTOM_H__
echo #define __JB_CUSTOM_H__
echo #define FT_EXPORT^(x^) __declspec^(dllexport^) x
echo #define FT_BASE^(x^) __declspec^(dllexport^) x
echo #endif) > jb_custom.h

• Build with VC Express for x64 or win32 target
• Put freetype.dll, freetype.lib, freetype.exp in lib folder at the same level with include:

freetype
  include
  lib

Configure and run make in cygwin shell

• 32 bit (use --with-msvcr-dll=/cygdrive/c/windows/SysWOW64/msvcr100.dll on 64 bit windows)

  cd /cygdrive/c/jdk8/
 ./configure  --with-target-bits=32 --with-freetype=/cygdrive/freetype/  
  make images

• 64 bit

  cd /cygdrive/c/jdk8/
 ./configure  --with-target-bits=64 --with-freetype=/cygdrive/freetype/  
  make images

OSX

XCode

• Login to https://developer.apple.com with your Apple ID. Download Xcode 4.6.3 and put Xcode.app into /Applications/Xcode4

The latest XCode can be used, but you need to run make with COMPILER_WARNINGS_FATAL=false

Command Line Tools

• Download and install Command Line Tools via XCode Preferences / Downloads or from https://developer.apple.com (for example, Command Line Tools, April 2014 for OS X Mountain Lion).

Freetype

• Install XQuartz or build Freetype from sources

cd freetype
./configure
./make
mkdir lib
cp objs/.libs/libfreetype.dylib lib/

Configure and build jdk

export MACOSX_DEPLOYMENT_TARGET=10.8
cd /path_to_jdk8/
bash configure --with-xcode-path=/Applications/Xcode4/Xcode4.app --with-freetype=/opt/X11/lib --with-freetype-include=/usr/X11/include/freetype2
make images

or

make COMPILER_WARNINGS_FATAL=false images

for the latest XCode
