Introduction

The libevtx source code can be build with different compilers:

  • Using GNU Compiler Collection (GCC)
    • Using Cygwin
  • Using Minimalist GNU for Windows (MinGW)
  • Using Microsoft Visual Studio

Or directly packaged with different package managers:

  • Using Debian package tools (DEB)
  • Using RedHat package tools (RPM)
  • Using Mac OS X pkgbuild

Getting the source

Source package

To retrieve the source package go to the downloads page and download the file named:

libevtx-alpha-<version>.tar.gz

To extract the source package run:

tar xfv libevtx-alpha-<version>.tar.gz

This will create the source directory:

libevtx-<version>

Git

Note that the git repository holds the development version of the source code.

If you are not developing it is recommended that you download a source package instead.

To retrieve the source from the git repository make sure to install:

  • git
  • aclocal
  • autoconf
  • automake
  • autopoint or gettextize
  • libtoolize
  • pkg-config

To download and prepare the source for building run:

git clone https://github.com/libyal/libevtx.git
cd libevtx/
./synclibs.sh
./autogen.sh

The source from the git repository will not work without synchronizing the library dependencies "./synclibs.sh" and having the autotools generate the necessary files "./autogen.sh".

Mac OS X

On Mac OS X the XCode command line tools no longer provide the autotools you can obtain them e.g. via MacPorts. Install the following packages:

sudo port install autoconf automake gettext libtool pkgconfig

Using GNU Compiler Collection (GCC)

Before you build the libevtx source code using the GNU Compiler Collection (GCC) you'll need to have compilation and build tools installed.

  • On a Linux system make sure you have build-essential (Debian-based) or the Development Tools (RedHat-based) packages installed.
  • On a Mac OS X system make sure you have XCode (with command line tools) or MacPorts (or equivalent) installed.

To build the libevtx source code change into the source directory and run the following commands:

./configure
make

You can install the binaries that were build by running:

sudo make install

By default this will install the binaries in /usr/local. If you want to change this to e.g. /usr, add the configuration option --prefix=/usr, e.g.

./configure --prefix=/usr

On Linux make sure libevtx.so is in the library cache. Normally it suffices to run:

sudo ldconfig

Verbose and debug output

To troubleshoot issues or for low-level format analysis libevtx supports verbose and debug output.

To enable verbose and debug output support add --enable-verbose-output and --enable-debug-output to configure, e.g.

./configure --enable-verbose-output --enable-debug-output

This will generate vast amounts of debug information on stderr when the tools are run with -v.

Static library

To make a static library add --enable-shared=no to configure, .e.g:

./configure --enable-shared=no

Static executables

Some distributions provide separate packages for static versions of libraries. Make sure you have a static versions of:

  • glibc

To make static executables add --enable-static-executables=yes to configure, .e.g:

./configure --enable-static-executables=yes

Python-bindings

To compile the Python-bindings you'll need the Python development files.

Make sure that on:

  • a Linux machine, you have python-dev (Debian-based) or python-devel (RedHat-based) installed.
  • a Mac OS X machine, XCode if you're using a different Python source tree see Mac OS X notes below.

Adding --enable-python when running ./configure will enable the Python-bindings to be build.

./configure --enable-python

Cygwin

If you want to use Cygwin to build libevtx make sure to have the following packages installed:

  • autoconf
  • automake
  • binutils
  • gcc-core
  • gettext
  • libiconv
  • libtool
  • make
  • pkg-config

After following the GNU Compiler Collection (GCC) build instructions you should end up with the following DLL:

libevtx/.libs/cygevtx-0.dll

And the following executables:

evtxtools/.libs/evtxexport.exe
evtxtools/.libs/evtxinfo.exe

Using the DLL

Make sure you use define LIBEVTX_DLL_IMPORT before including <libevtx.h>.

To be able to use the DLL on other systems than the build system you'll also need to provide:

  • cygwin1.dll

Mac OS X

Universal binary

With XCode you can build a Mac OS X universal binary to run on multiple architectures. The supported architectures and exact command differs per version of Mac OS X.

Mac OS X 10.4

E.g. on Mac OS X 10.4 to build an PPC and Intel 32-bit multi binary, run the following commands:

CFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386" \
LDFLAGS="-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386" \
./configure --disable-dependency-tracking
make
make install

Mac OS X 10.6

E.g. on Mac OS X 10.6 to build an Intel 32-bit and 64-bit multi binary, run the following commands:

CFLAGS="-isysroot /Developer/SDKs/MacOSX10.6.sdk -arch x86_64 -arch i386" \
LDFLAGS="-Wl,-syslibroot,/Developer/SDKs/MacOSX10.6.sdk -arch x86_64 -arch i386" \
./configure --disable-dependency-tracking
make
make install

Mac OS X 10.7

E.g. on Mac OS X 10.7 to build an Intel 32-bit and 64-bit multi binary, run the following commands:

CFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk -arch x86_64 -arch i386" \
LDFLAGS="-Wl,-syslibroot,/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk -arch x86_64 -arch i386" \
./configure --disable-dependency-tracking
make
make install

libtoolize

If you find that libtoolize is missing use glibtoolize instead.

Python-bindings

Mac OS X comes with multiple platform specific build Python versions. If you install a different version of Python on Mac OS X make sure that when building and running the Python-bindings you're using the correct version otherwise it will likely result in one of the following errors:

Fatal Python error: Interpreter not initialized (version mismatch?)

Fatal Python error: PyThreadState_Get: no current thread

To build against a specific version you can tell configure where to look:

CFLAGS=-I/Library/Frameworks/Python.framework/Versions/2.7/include/ \
LDFLAGS=-L/Library/Frameworks/Python.framework/Versions/2.7/lib/ \
./configure --enable-python --with-pyprefix

Adding --with-pyprefix tells configure to use Python to determine where to install the Python-bindings.

Sun Solaris

To build libevtx on Sun Solaris make sure that /usr/ccs/bin and /usr/sfw/bin are defined in the PATH environment variable.

Using Minimalist GNU for Windows (MinGW)

To compile libevtx using MinGW you'll need:

  • MinGW

To build use:

mingw32-configure --prefix=/opt/local/i386-mingw32 --enable-winapi=yes
mingw32-make

It is recommended that you use WINAPI support but it is possible to compile libevtx without it (--enable-winapi=no). The default behavior is that configure will try to auto-detect MinGW and enable WINAPI support.

If mingw32-configure and mingw32-make are not available you can build it with:

./configure --host=i386-mingw32 --prefix=/opt/local/i386-mingw32 --enable-winapi=yes
make

If this does not work try a script similar to the following:

#!/bin/sh
CC=/opt/local/bin/i386-mingw32-gcc
CXX=/opt/local/bin/i386-mingw32-g++
AR=/opt/local/bin/i386-mingw32-ar
OBJDUMP=/opt/local/bin/i386-mingw32-objdump
RANLIB=/opt/local/bin/i386-mingw32-ranlib
STRIP=/opt/local/bin/i386-mingw32-strip
MINGWFLAGS="-mwin32 -mconsole -march=i586 "
CFLAGS="$MINGWFLAGS"
CXXFLAGS="$MINGWFLAGS"

CC=$CC CXX=$CXX AR=$AR OBJDUMP=$OBJDUMP RANLIB=$RANLIB STRIP=$STRIP ./configure --host=i586-mingw32msvc --prefix=/opt/local/i386-mingw32 --enable-winapi=yes
CC=$CC CXX=$CXX AR=$AR OBJDUMP=$OBJDUMP RANLIB=$RANLIB STRIP=$STRIP CFLAGS="$CFLAGS" CXXFLAGS="$CXXFLAGS" make

If you get compiler errors like:

#error WINAPI file open function for Windows 2000 or earlier NOT implemented yet

That means WINVER is not set or set to a version predating Windows XP (0x0501) and you'll have to set WINVER manually like:

CFLAGS=-DWINVER=0x0501 ./configure --host=i386-mingw32 --enable-winapi=yes

You should end up with the following DLL:

libevtx/.libs/libevtx-1.dll

And the following executables:

evtxtools/.libs/evtxexport.exe
evtxtools/.libs/evtxinfo.exe

To install libevtx and tools in the MinGW build tree use:

sudo make install

Using MSYS-MinGW

MSYS-MinGW provides means to run configure on Windows.

Installing MSYS-MinGW

Download mingw-get from http://www.mingw.org/

Install mingw-get, you'll only need the command line interface.

More information can be found here.

Start a command prompt and change into the MinGW binaries directory:

cmd.exe
cd C:\mingw\bin\

To install the required MinGW and MSYS packages run:

mingw-get install binutils mingw-runtime w32api libgmp libmpc libiconv pthreads gettext libz gcc-core mingw32-make msys

Building with MSYS-MinGW

Start the MSYS shell:

C:\MinGW\msys\1.0\msys.bat

Make sure the MinGW directory is mounted, otherwise run the following command to mount:

mkdir /mingw
mount C:\\MinGW /mingw

Note: make sure to use the the double \ and that /mingw has no trailing /

To build use:

tar xfv libevtx-alpha-<version>.tar.gz
cd libevtx-<version>/
CPPFLAGS=-DWINVER=0x0501 ./configure --prefix=/mingw
make

Using the DLL

Make sure you use define LIBEVTX_DLL_IMPORT before including <libevtx.h>.

To be able to use the DLL on other systems than the build system you'll also need to provide:

  • libgcc_s_dw2-1.dll (or equivalent)

Troubleshooting

While running make I get an error similar to the following:

libclocale_locale.c: In function 'libclocal_local_get_decimal_point':
libclocale_locale.c:357:2: warning implicit declaration of function 'GetLocaleInfoEx' [-Wimplicit-function-declaration]
libclocale_locale.c:358:7: error: 'LOCALE_NAME_USER_DEFAULT' undeclared (first use in this function)
libclocale_locale.c:358:7: note: each undeclared identifier is reported only once for every function it appears in

The version of MinGW does not support a WINAPI version of Vista or later (0x0600) try setting WINVER to 0x0501.

Using Microsoft Visual Studio

Before you build libevtx using Microsoft Visual Studio you'll need to have it installed. The libevtx packages comes with Microsoft Visual Studio files for version 2008. Version 2010 is able to convert these files into its newer versions.

The Microsoft Visual Studio express version is sufficient. Note that if you want to build 64-bit version with the express version you'll need at least 2010. Also see the section: Microsoft Visual Studio 2010 express and 64-bit compilation.

Note that if you want to build libevtx from source checked out of git with Visual Studio make sure the autotools are able to make a distribution package of libevtx before trying to build it. You can create distribution package by running: "make dist".

Verbose and debug output

To troubleshoot issues or for low-level format analysis libevtx supports verbose and debug output.

To enable verbose and debug output support edit:

common\config_winapi.h

Add the following definitions:

#define HAVE_VERBOSE_OUTPUT     1
#define HAVE_DEBUG_OUTPUT       1

Python-bindings

To compile the pyevtx Python-bindings you'll need the Python development files which are part of the Python.org windows installer package.

The Microsoft Visual Studio files are configured to look in:

C:\Python2.7\

If you want to have the Python development files in a different location you'll have to change the pyevtx Microsoft Visual Studio settings.

Note that the VSDebug build of the Python-bindings will fail since the Python development files do not come with python2.7_d.lib.

If you do not intend to build the Python-bindings you can safely ignore build errors regarding: pyevtx.

Building

Open the file:

msvscpp\libevtx.sln

Note that the project files contain a Release and VSDebug configuration. The VSDebug builds the binaries with debug information. Note that this is not the same as debug output.

Make sure to check if your build environment defines the correct WINVER for your build. The code uses WINAPI version specific functions based on WINVER. You can define a custom WINVER in the Microsoft Visual Studio C++ project files or in common\config_winapi.h

And build the solution. The build files will be places in:

msvscpp\Release\

Using MSBuild

Another way to build libevtx with Visual Studio is to use MSBuild via the command line. MSBuild can be installed as part of the Microsoft.NET Framework.

First set-up the Visual Studio variables:

C:\Program Files\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat

Next run MSBuild:

msbuild msvscpp\libevtx.sln /p:Configuration=Release;Platform=Win32

Using the DLL

Make sure you use define LIBEVTX_DLL_IMPORT before including <libevtx.h>.

To be able to use the DLL on other systems than the build system you'll also need to provide:

  • the Microsoft Visual C++ Run-Time DLL (part of the Visual C++ Redistributable package)

64-bit with Microsoft Visual Studio express

To build a 64-bit version of libevtx with Microsoft Visual Studio express you'll need at least the 2010 version.

Microsoft Visual Studio 2010

First make sure to enabling 64-bit compilation support on Microsoft Visual Studio 2010 express. Since this can be a tedious process, some relevant links:

If you have set it up correctly the following should work:

Go to:

Configuration manager -> Active solution platform

Select "<New>"

  • Type or select the new platform: "x64"
  • Copy settings from: "Win32"
  • Create new project platforms: enabled

Additionally for every project change:

Configuration Properties -> General -> Platform Toolset

Into "Windows7.1SDK"

If you've Cygwin installed on your Visual Studio build machine you can try running one of the following scripts to add the x64 settings for you:

sh msvscpp/scripts/vs2008_x64.sh

Make sure to convert the solution first from 2008 to 2010.

sh msvscpp/scripts/vs2010_x64.sh

Using Debian package tools (DEB)

To build libevtx using the Debian package tools make sure you have the following packages installed:

sudo apt-get install build-essential debhelper fakeroot autotools-dev python-dev

If you downloaded the source using git make sure to run ./configure at least once to generate the dpkg packaging files.

To build the Debian packages change into the source directory and run:

cp -rf dpkg debian
dpkg-buildpackage -rfakeroot

This will create the following files in the parent directory:

libevtx_<version>-1_<arch>.deb
libevtx-dev_<version>-1_<arch>.deb
libevtx-python_<version>-1_<arch>.deb
libevtx-tools_<version>-1_<arch>.deb

To install, e.g. the library:

sudo dpkg -i libevtx_<version>-1_<arch>.deb

Using RedHat package tools (RPM)

To build libevtx using the RedHat package tools make sure you have the following packages installed:

yum install rpm-build python-devel

To build:

mv libevtx-alpha-<version>.tar.gz libevtx-<version>.tar.gz
rpmbuild -ta libevtx-<version>.tar.gz

This will create the following files in the rpmbuild directory:

~/rpmbuild/RPMS/<arch>/libevtx-<version>-1.<arch>.rpm
~/rpmbuild/RPMS/<arch>/libevtx-devel-<version>-1.<arch>.rpm
~/rpmbuild/RPMS/<arch>/libevtx-python-<version>-1.<arch>.rpm
~/rpmbuild/RPMS/<arch>/libevtx-tools-<version>-1.<arch>.rpm
~/rpmbuild/SRPMS/libevtx-<version>-1.src.rpm

To install, e.g. the library:

sudo rpm -ivh libevtx-<version>-1.<arch>.rpm

Mac OS X package

pkgbuild can be used to create a Mac OS X package.

The following instructions show how to build libevtx.pkg and libevtx.dmg from the command line.

First build libevtx with Python-bindings:

./configure --prefix=/usr --enable-python --with-pyprefix
make

Next install the build files using DESTDIR

make install DESTDIR=$PWD/tmp

This will make sure that library paths in the dylib file is set correctly for distribution. This is not the case when you use:

./configure --prefix=$PWD/tmp

You can check the library paths in the dylib by running:

otool -LT tmp/usr/lib/libevtx.1.dylib

After running "make install" the binaries are installed in:

$PWD/tmp/

If you are planning to distribute libevtx.pkg make sure it contains a copy of LGPL license:

mkdir -p $PWD/tmp/usr/share/doc/libevtx
cp AUTHORS COPYING NEWS README $PWD/tmp/usr/share/doc/libevtx

To create the package (directory):

pkgbuild --root $PWD/tmp --identifier com.github.libyal.libevtx --version <version> --ownership recommended ../libevtx-<version>.pkg

To create a distributable disk image:

hdiutil create ../libevtx-<version>.dmg -srcfolder ../libevtx-<version>.pkg -fs HFS+
