-You must have X11 and the X11 developer headers and libraries installed;
-otherwise, you will not be able to build or install GTK+, and will only
-be able to build TShark. The X11 and X11 SDK that come with Mac OS X
-releases starting with Panther can be used to build and run Wireshark.
+for details. For Xcode 4, you will need to install the command-line
+tools; select Preferences from the Xcode menu, select Downloads in the
+Preferences window, and install Command Line Tools.
You must also have GLib and, if you want to build Wireshark as well as
-TShark, GTK+. The macosx-setup.sh script can be used to download, patch
-as necessary, build, and install those libraries and the libraries on
-which they depend; it will, by default, also install other libraries
-that can be used by Wireshark and TShark. The versions of libraries to
-download are specified by variables set early in the script; you can
-comment out the settings of optional libraries if you don't want them
-downloaded and installed.
+TShark, you must have also Qt installed. You can download precompiled
+Qt packages and source code from
+
+ https://www.qt.io/download-open-source/
+
+or use the tools/macos-setup.sh script described below.
+
+You should have CMake installed; you can download binary distributions
+for macOS from
+
+ https://cmake.org/download/
+
+The tools/macos-setup.sh script can be used to download, patch as
+necessary, build as necessary, and install those libraries and the
+libraries on which they depend, along with tools such as CMake; it will,
+by default, also install other libraries that can be used by Wireshark
+and TShark. The versions of libraries and tools to download are
+specified by variables set early in the script; you can comment out the
+settings of optional libraries if you don't want them downloaded and
+installed. Before running the tools/macos-setup.sh script, and before
+attempting to build Wireshark, make sure your PKG_CONFIG_PATH
+environment variable's setting includes /usr/local/lib/pkgconfig.
+
+The tools/macos-setup.sh script must be run from the top-level source
+directory.
After you have installed those libraries:
-If you are building from a Subversion tree, rather than from a source
-distribution tarball, run the autogen.sh script. This should not be
-necessary if you're building from a source distribution tarball, unless
-you've added new source files to the Wireshark source.
+ 1. If you have installed Qt into some non-standard place, as is
+ distinctly possible with the build included with
+ macos-setup.sh, you must inform cmake by either including its
+ "bin" directory as part of the PATH environment variable or
+ setting CMAKE_PREFIX_PATH to the directory above Qt's "lib"
+ directory. For Qt 5.8 installed into one's home directory,
+ for instance:
-Then run the configure script, and run make to build Wireshark.
+ % export CMAKE_PREFIX_PATH=~/Qt5.8.0/5.8/clang_64
-If you upgrade the major release of Mac OS X on which you are building
-Wireshark, we advise that, before you do any builds after the upgrade,
-you do, in the build directory:
+ This step is unnecessary if you've used a recent version of
+ Homebrew, as the CMake build scripts will find Qt.
+
+ 2. Make a directory in which Wireshark is to be built, separate
+ from the top-level source directory for Wireshark - it can be a
+ subdirectory of that top-level source directory;
- If you are building from a release tarball:
- make distclean
+ 3. cd to that directory, and run CMake, with an argument that is a
+ path to the top-level source directory;
- If you are building from SVN:
- make maintainer-clean
- ./autogen.sh
+ 4. When CMake finishes, run make to build Wireshark.
-Then re-run the configure script and rebuild from scratch.
+For example, to build Wireshark in a subdirectory of the top-level
+source directory, named "build", do, from the top-level source
+directory;
+
+ mkdir build
+ cd build
+ cmake ..
+ make
+
+It is also possible to use the Xcode IDE to build and debug Wireshark
+using cmake's Xcode generator. Create a separate build directory, as
+described above and run cmake with the "-G Xcode" argument to create
+a Xcode project file in the current directory.
+
+ cmake -G Xcode ..
+
+ 1. Double click Wireshark.xcodeproj
+
+ 2. Choose to create schemes manually
+
+ 3. Create a scheme for the ALL_BUILD target
+
+ 4. Edit the scheme, go to the run configuration and select Wireshark.app
+ as executable
+
+If you upgrade the major release of macOS on which you are building
+Wireshark, we advise that, before you do any builds after the upgrade,
+you remove the build directory and all its subdiretories, and repeat the
+above process, re-running CMake and rebuilding from scratch.
-On Snow Leopard (10.6), if you are building on a machine with a 64-bit
-processor (with the exception of the early Intel Core Duo and Intel Core
-Solo machines, all Apple machines with Intel processors have 64-bit
-processors), the C/C++/Objective-C compiler will build 64-bit by
-default.

+build 64-bit by default.
This means that you will, by default, get a 64-bit version of Wireshark.
One consequence of this is that, if you built and installed any required
-or optional libraries for Wireshark on an earlier release of Mac OS X,
-those are probably 32-bit versions of the libraries, and you will need
-to un-install them and rebuild them on Snow Leopard (10.6), to get 64-bit
-versions.

Some required and optional libraries require special attention if you

GLib - the GLib configuration script determines whether the system's
libiconv is GNU iconv or not by checking whether it has libiconv_open(),
and the compile will fail if that test doesn't correctly indicate
-whether libiconv is GNU iconv. In Mac OS X, libiconv is GNU iconv, but
-the 64-bit version doesn't have libiconv_open(); a workaround for this
-is to replace all occurrences of "libiconv_open" with "iconv_open" in
-the configure script before running the script. The macosx-setup.sh

libgcrypt - the libgcrypt configuration script attempts to determine
which flavor of assembler-language routines to use based on the platform
type determined by standard autoconf code. That code uses uname to

"i386" as the processor type on Intel machines, even Intel machines with
64-bit processors, so it will attempt to assemble the 32-bit x86

is to run the configure script with the --disable-asm argument, so that

-PortAudio - when compiling on Mac OS X, the configure script for the
-pa_stable_v19_20071207 version of PortAudio will cause certain
-platform-dependent build environment #defines to be set in the
-Makefile rules, and to cause a universal build to be done; those
-#defines will be incorrect for all but one of the architectures for
-which the build is being done, and that will cause a compile-time error

+If you want to build Wireshark installer packages on a system that
+doesn't include Xcode 3.x or earlier, you will need to install some
+additional tools. From the Xcode menu, select the Open Developer Tool
+menu, and then select More Developer Tools... from that menu. That will
+open up a page on the Apple Developer Connection Web site; you may need
+a developer account to download the additional tools. Download the
+Auxiliary Tools for Xcode package; when the dmg opens, drag all its
+contents to the Contents/Applications subdirectory of the Xcode.app
+directory (normally /Applications/Xcode.app/Contents/Applications); then
+copy .../Contents/Applications/PackageMaker.app/Contents/MacOS/PackageMaker
+to /usr/bin/packagemaker (the PackageMaker app, when run from the
+command line rather than as a double-clicked app, is the packagemaker
+command).
