++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++ [[ChapterLibraries]] == Library Reference [[ChLibIntro]] === Introduction Several libraries are needed to build and run Wireshark. Most of them are split into three packages: . 'Runtime'. System and third party libraries such as 'MSVCR110.dll' and 'libglib-2.0-0.dll'. . 'Developer'. Documentation, header files, import libraries, and other files needed for compilation. . 'Source'. Library sources, which are usually not required to build Wireshark. [TIP] .Our libraries are freely available ==== All libraries required to build Wireshark on Windows are available for download at http://anonsvn.wireshark.org/wireshark-win32-libs/trunk/packages/[] and http://anonsvn.wireshark.org/wireshark-win64-libs/trunk/packages/[]. See <> for an easier way to install them. ==== [[ChLibsFormat]] === Binary library formats Binary libraries are available in different formats, depending on the C compiler used to build it and of course the platform they were built for. [[ChLibsFormatUnix]] ==== Unix If you have installed unix binary libraries on your system, they will match the C compiler. If not already installed, the libraries should be available as a package from the platform installer, or you can download and compile the source and then install the binaries. [[ChLibsFormatWin32]] ==== Win32: MSVC Most of the Win32 binary libraries you will find on the web are in this format. You will recognize MSVC libraries by the .lib/.dll file extension. [[ChLibsFormatWin32Cygwin]] ==== Win32: cygwin gcc Cygwin provides most of the required libraries (with file extension .a or .lib) for Wireshark suitable for cygwin's gcc compiler. [[ChLibsSetup]] === Win32: Automated library download [[ChLibsSetupInitial]] ==== Initial download You can download and install all required libraries by using the `setup` target of 'Makefile.nmake' from the source package. [TIP] .Use the setup target ==== It's a really good idea to use the Win32 automated library download to install the required libraries as it makes this download very easy. Before you start the download, you must have installed both the required tools (see <>) and the Wireshark sources (see <>). ==== By default the libraries will be downloaded and installed into 'C:\wireshark-win32-libs' for x86 builds and 'C:\wireshark-win64-libs' for x86_64 builds. You can change this to any other location by editing 'config.nmake' and changing the line containing WIRESHARK_LIB_DIR to your favourite place. You must use an absolute path. Then run the command ---- > nmake -f Makefile.nmake setup ---- This will first check for all the various tools needed to build Wireshark as described in <>. Then it will download the zipped libraries (together around 30MB!) from the server location at http://anonsvn.wireshark.org/wireshark-win32-libs/trunk/packages/[] into the directory specified by WIRESHARK_LIB_DIR and install (unzip) all required library files there. If you have problems downloading the library files, you might be connected to the internet through a proxy. In this case see the wget proxy comment in <>. [[ChLibsSetupUpdate]] ==== Update of a previous download As new versions of the libraries become available, maybe with bugfixes or some new functionality, your libraries get outdated. You could simply remove everything in the WIRESHARK_LIB_DIR dir and call the `setup` target again, but that would require a download of every file again, which isn't necessary. The following will bring your libraries up to date: * Update your Wireshark sources to the latest SVN files (see <>), so the zip filenames in the setup target of Makefile.nmake are in sync with the library zip files on the server. * Execute the library setup command as described above. + -- ---- > nmake -f Makefile.nmake setup ---- Note that this command will automatically do a `clean-setup` which will remove all files previously unzipped from the downloaded files in your WIRESHARK_LIB_DIR library path (all the subdirs, e.g. '$$c:\wireshark-win32-libs\gtk+$$'), except for the zip files located at the toplevel, which are the files downloaded the last time(s). Also note that as wget will download only the missing (updated) files, existing zip files in the WIRESHARK_LIB_DIR dir won't be downloaded again. Remaining (outdated) zip files shouldn't do any harm. -- [[ChLibsGtk]] === GTK+ / GLib / GDK / Pango / ATK / GNU gettext / GNU libiconv The Glib library is used as a basic platform abstraction library, it's not related to graphical user interface (GUI) things. For a detailed description about GLib, see <>. The GTK and its dependent libraries are used to build Wireshark's GUI. For a detailed description of the GTK libraries, see <>. All other libraries are dependent on the two libraries mentioned above, you will typically not come in touch with these while doing Wireshark development. As the requirements for the GLib/GTK libraries have increased in the past, the required additional libraries depend on the GLib/GTK versions you have. The 2.x versions require all mentioned libs. [[ChLibsUnixGTK]] ==== Unix The GLib/GTK+ libraries are available for many unix-like platforms and Cygwin. If these libraries aren't already installed and also aren't available as a package for your platform, you can get them at http://www.gtk.org/download.html[].
