This repository provides a set of scripts which will help you compile VirtualBox easily.

You can find the official manual to compile VirtualBox in Windows from the official site, but it's too obsolete to follow at this time. So, we wrote python scripts which prepare required libraries for compilation, and compile VirtualBox automatically.

What you need to do is only to install pre-requisites for the compilation, and run the scripts.

• It downloads or compiles the followings: 7-Zip, MinGW, SDL, SSL, cURL, Qt5
• It creates and registers a credential which is needed to compile drivers in Windows.
• It manages dependencies in the compilation.
• It compiles VirtualBox binaries.

• Windows 10
• Python (≥ 3.8)
• Enough spaces (at least 20GB)

To build VirtualBox via the scripts, you should follow the steps below.

Before using the scripts, you need to install the followings.

• Visual Studio 2010 (Tested on Professional)
• Visual Studio 2010 SP1
• WinSDK 7.1
• WinSDK 8.1
• WinDDK 7.1
• SSL 32bit
• SSL 64bit

If at least one of them is not installed properly, you could be in trouble with compile errors afterwards. And, we recommend you install them in their default paths.

Before going into any steps, you should satisfy the followings:

• Test Mode
• Root Privilege

You can turn on the test mode with the following:

bcdedit /set testsigning on

Note that you MUST reboot your PC when you turned on the test mode for the first time.

And, you should execute any scripts in this repository with root-privilege(Administrator). Unless, you will confront unexpected issues afterwards.

You should download from the official site the sources of VirtualBox, which you want to compile. And copy the sources into C:/VBoxBuild/VirtualBox. Scripts will use C:/VBoxBuild as a default working directory for compilation.

Clone this repository via:

git clone https://github.com/VirtualBoBs/build-virtualbox-in-windows.git

Run script/setup.py.

It will configure all the requirements for your compilation.

Run script/build.py.

Please make sure that the prior setup stage has been accomplished.

It will build the components of VirtualBox. You can find the compiled binaries in C:/VBoxBuild/VirtualBox/out/win.amd64/release/bin.

If you've finished Step 1~5, building the binaries needs Step 6 only.

When you run the GUI version of VirtualBox(VirtualBox.exe), you need dynamic libraries of both Qt and cURL library. You can run it via:

SET PATH=%PATH%;C:\VBoxBuild\Qt\qt5-x64\bin
SET PATH=%PATH%;C:\VBoxBuild\curl\x64

C:\VBoxBuild\VirtualBox\out\win.amd64\release\bin\VirtualBox.exe

The default setting provides disabled-hardening on the VirtualBox binary, so you can attach any kind of debugger on the running process of compiled VirtualBox.

A) Unfortunately, now our script does not handle multiple certificates being generated during the Setup step. You need to run it only once unlike the Build step. And here is the solution:

1. Run certmgr.msc
2. Delete all the certificates named MyTestCertificate in the Certificates - Personal
3. Start from the Setup step.

We use Github Issue as its primary upstream bug tracker. Bugs found when running scripts should be reported via:

• https://github.com/VirtualBoBs/build-virtualbox-in-windows/issues

Especially, let us know if you can not download files automatically in the scripts. Old URLs in the scripts might be the causes.

You can contact us via:

• Send a mail via a leg of bird

• Wish to God your genuine belief
