I. Windows

Requirements for Building TrueCrypt for Windows:

• Microsoft Visual C++ 2008 SP1 (Professional Edition or compatible)
• Microsoft Visual C++ 1.52 (available from MSDN Subscriber Downloads)
• Microsoft Windows SDK for Windows 7 (configured for Visual C++)
• Microsoft Windows Driver Kit 7.1.0 (build 7600.16385.1)
• RSA Security Inc. PKCS #11 Cryptographic Token Interface (Cryptoki) 2.20 header files (available at ftp://ftp.rsasecurity.com/pub/pkcs/pkcs-11/v2-20)
• NASM assembler 2.08 or compatible
• gzip compressor

IMPORTANT:

The 64-bit editions of Windows Vista and later versions of Windows, and in some cases (e.g. playback of HD DVD content) also the 32-bit editions, do not allow the TrueCrypt driver to run without an appropriate digital signature. Therefore, all .sys files in official TrueCrypt binary packages are digitally signed with the digital certificate of the TrueCrypt Foundation, which was issued by a certification authority. At the end of each official .exe and .sys file, there are embedded digital signatures and all related certificates (i.e. all certificates in the relevant certification chain, such as the certification authority certificates, CA-MS cross-certificate, and the TrueCrypt Foundation certificate). Keep this in mind if you compile TrueCrypt and compare your binaries with the official binaries. If your binaries are unsigned, the sizes of the official binaries will usually be approximately 10 KB greater than sizes of your binaries (there may be further differences if you use a different version of the compiler, or if you install a different or no service pack for Visual Studio, or different hotfixes for it, or if you use different versions of the required SDKs).

Instructions for Building TrueCrypt for Windows:

1. Create an environment variable 'MSVC16_ROOT' pointing to the folder 'MSVC15' extracted from the Visual C++ 1.52 self-extracting package.

   Note: The 16-bit installer MSVC15\SETUP.EXE cannot be run on 64-bit Windows, but it is actually not necessary to run it. You only need to extract the folder 'MSVC15', which contains the 32-bit binaries required to build the TrueCrypt Boot Loader.

2. If you have installed the Windows Driver Development Kit in another directory than '%SYSTEMDRIVE%\WinDDK', create an environment variable 'WINDDK_ROOT' pointing to the DDK installation directory.

3. Copy the PKCS #11 header files to a standard include path or create an environment variable 'PKCS11_INC' pointing to the directory where the PKCS #11 header files are installed.

4. Open the solution file 'TrueCrypt.sln' in Microsoft Visual Studio 2008.

5. Select 'All' as the active solution configuration.

6. Build the solution.

7. If successful, there should be newly built TrueCrypt binaries in the 'Release' folder.

II. Linux and Mac OS X

Requirements for Building TrueCrypt for Linux and Mac OS X:

• GNU Make
• GNU C++ Compiler 4.0 or compatible
• Apple Xcode (Mac OS X only)
• NASM assembler 2.08 or compatible (x86/x64 architecture only)
• pkg-config
• wxWidgets 2.8 shared library and header files installed or wxWidgets 2.8 library source code (available at http://www.wxwidgets.org)
• FUSE library and header files (available at http://fuse.sourceforge.net and http://code.google.com/p/macfuse)
• RSA Security Inc. PKCS #11 Cryptographic Token Interface (Cryptoki) 2.20 header files (available at ftp://ftp.rsasecurity.com/pub/pkcs/pkcs-11/v2-20) located in a standard include path or in a directory defined by the environment variable 'PKCS11_INC'.

Instructions for Building TrueCrypt for Linux and Mac OS X:

1. Change the current directory to the root of the TrueCrypt source code.

2. If you have no wxWidgets shared library installed, run the following command to configure the wxWidgets static library for TrueCrypt and to build it:

   $ make WX_ROOT=/usr/src/wxWidgets wxbuild

   The variable WX_ROOT must point to the location of the source code of the wxWidgets library. Output files will be placed in the './wxrelease/' directory.

3. To build TrueCrypt, run the following command:

   $ make

   or if you have no wxWidgets shared library installed:

   $ make WXSTATIC=1

4. If successful, the TrueCrypt executable should be located in the directory 'Main'.

By default, a universal executable supporting both graphical and text user interface is built. To build a console-only executable, which requires no GUI library, use the 'NOGUI' parameter:

$ make NOGUI=1 WX_ROOT=/usr/src/wxWidgets wxbuild
$ make NOGUI=1 WXSTATIC=1

III. FreeBSD and OpenSolaris
