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

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 git@github.com:JetBrains/jdk8u.git
cd jdk8u
./getModules.sh

Windows:

git config --global core.autocrlf false
git clone git@github.com: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 git@github.com: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

Build Freetype:

Download sources

Execute the following script in builds\windows\vc2010

(echo ^<?xml version="1.0" encoding="utf-8"?^>

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_WARNINGSFATAL=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

make COMPILER_WARNINGS_FATAL=false images

for the latest XCode
