This documentation explains how to compile Capstone for:

• Windows CE 7, a.k.a, Windows Embedded Compact 7, on ARMv7.
• Windows CE 8, a.k.a, Windows Embedded Compact 2013, on ARMv7.

To build Capstone for a different platform, please refer to COMPILE.TXT.

Prerequisites

We support the following scenario regarding the build machine:

• Build running on Microsoft Windows.
• The C Software Develepment Kit of the target Windows CE device installed.
• Only for Windows CE 7:
  • C compiler toolchain installed, targetting Windows Embedded Compact 7 on ARMv7. We recommend the toolchain provided with Windows Embedded Compact 7 toolkit, as the toolchain originally provided with Visual Studio 2008 is relatively old.

Before building Capstone for Windows CE 7 (respectively, Windows CE 8), the build script windowsce/make_windowsce7-armv7.bat (respectively, windowsce/make_windowsce8-armv7.bat) needs to be modified. The variables specified in the rest of this section are set in this script file.

Toolchain specification

The following information need to be specified in the build script in order to perform the build:

• set WINCE_TOOLCHAIN_ROOT= is the path of the root directory of the Windows CE toolchain. To build for Windows CE 7, this should be set to the Windows Embedded Compact 7 toolchain. To build for Windows CE 8, this should be set to the device toolchain. Examples:

  • For Windows CE 7:

  set WINCE_TOOLCHAIN_ROOT=C:\WINCE700\sdk
  

  • For Windows CE 8:

  set WINCE_TOOLCHAIN_ROOT=C:\Windows_CE_Tools\SDKs\SDK_HW90270\Sdk
  

• set TOOLCHAIN= is a semicolon-separated list of the paths of the directories containing the binaries of the Windows CE toolchain. For example:

set TOOLCHAIN=%WINCE_TOOLCHAIN_ROOT%\Bin\i386\Arm;%WINCE_TOOLCHAIN_ROOT%\Bin\i386

• set INCLUDE= is a semicolon-separated list of the paths of the directories containing the C header files of the Windows CE device SDK. To build for Windows CE 7, this should also include the directories containing the C header files of the Windows Embedded Compact 7 toolchain. Examples:

  • For Windows CE 7:

  set INCLUDE=C:\Program Files (x86)\Windows CE Tools\SDKs\Symbol MC3200c70 Windows CE 7.0 PSDK\Include\Armv4i;C:\WINCE700\public\common\sdk\inc
  

  • For Windows CE 8:

  set INCLUDE=%WINCE_TOOLCHAIN_ROOT%\Inc;%WINCE_TOOLCHAIN_ROOT%\crt\Include
  

• set LIBPATH= is a semicolon-separated list of the paths of the directories containing the library (i.e., .LIB) files of the Windows CE 7 device SDK. Examples:

  • For Windows CE 7:

  set LIBPATH=C:\Program Files (x86)\Windows CE Tools\SDKs\Symbol MC3200c70 Windows CE 7.0 PSDK\Lib\ARMv4I
  

  • For Windows CE 8:

  set LIBPATH=%WINCE_TOOLCHAIN_ROOT%\Lib\ARMV7\retail;%WINCE_TOOLCHAIN_ROOT%\Crt\Lib\ARM
  

• set LIBS= is a space-separated list of linker directives controlling library search. Examples:

  • For Windows CE 7:

  set LIBS=-nodefaultlib:oldnames.lib -nodefaultlib:libcmtd.lib -nodefaultlib:libcmt.lib coredll.lib corelibc.lib
  

  • For Windows CE 8:

  set LIBS=coredll.lib
  

Capstone binary format

By default, the build script produces a dynamic link library (i.e., .DLL). In order to produce a static library (i.e., .LIB) instead, the SHARED variable needs to be set to 0, i.e.:

set SHARED=0

Architectures supported at runtime

Capstone supports the following architectures: ARM, ARM64 (AArch64), M68K, MIPS, PowerPC, Sparc, SystemZ, x86 and XCore. However, Capstone can be configured in order to select which architectures need to be supported at runtime. This is controlled via the variable DISASM_ARCH_LIST, which is a space-separated list that is a combination of the following names:

• ARM
• ARM64
• M68K
• MIPS
• POWERPC
• SPARC
• SYSZ
• X86
• XCORE.

By default, DISASM_ARCH_LIST includes support for all architectures supported by Capstone. For example:

set DISASM_ARCH_LIST=ARM ARM64 X86

will produce a Capstone binary that supports the following architectures: ARM, ARM64 and x86.

Features customization

Capstone has a list of features that can be controlled when needed. Each feature is controlled through setting a variable from the following list:

• In order to produce a smaller binary that provides a subset of the features of Capstone, but still supports all the selected architectures, please specify the following:

  set DIET_MODE=1
  

  By default, this variable is set to 0.

• By default, Capstone uses the default system-provided dynamic memory management functions (e.g., malloc(), realloc(), free()) for its internal memory management. However, Capstone can instead be configured to call custom memory management functions provided by client applications. In order to enable this behavior, set the following:

  set USE_SYS_DYN_MEM=0
  

• In order to produce a smaller Capstone binary, support for the x86 architecture can be more limited. In order to do so, set the following:

  set X86_REDUCE=1
  

  By default, this is set to 0.

• If the AT&T disassembly style of the x86 architecture is never needed at runtime, then disabling support for it can produce a smaller Capstone binary. To do this, please set the following:

  set X86_ATT_DISABLE=1
  

  By default, this is set to 0.

Please refer to docs/README for more details on these features.
