This file tries to help building Wireshark for (Mac) OS X (Wireshark
does not work on earlier versions of Mac OS).
You must have the developer tools (called Xcode) installed. For
versions of OS X up to and including Snow Leopard, Xcode 3 should be
available on the install DVD; Xcode 4 is available for download from
developer.apple.com and, for Lion and later releases, from the Mac App
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 for releases from Panther to Lion can be used to build and run
Wireshark. Mountain Lion does not include X11; you should install X11
from elsewhere, such as
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. Before running the macosx-setup.sh script,
and before attempting to build Wireshark, make sure your PKG_CONFIG_PATH
environment variable's setting includes both /usr/X11/lib/pkgconfig
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.
Then run the configure script, and run make to build Wireshark.
If you upgrade the major release of 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:
If you are building from a release tarball:
If you are building from SVN:
Then re-run the configure script and rebuild from scratch.
On Snow Leopard (10.6) and later releases, 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.
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 OS X, those
are probably 32-bit versions of the libraries, and you will need to
un-install them and rebuild them on your current version of OS X, to get
Some required and optional libraries require special attention if you
install them by building from source code on Snow Leopard and later
releases; the macosx-setup.sh script will handle that for 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 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 setup
script will patch GLib to work around this.
GTK+ - GTK+ 2.24.10, at least, doesn't build on Mountain Lion with the
CUPS printing backend - either the CUPS API changed incompatibly or the
backend was depending on non-API implementation details. The
macosx-setup.sh setup script will, on Mountain Lion and later, configure
GTK+ with the CUPS printing backend disabled.
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
determine the processor type; however, in Mac OS X, uname always reports
"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
assembler-language routines, which will fail. The workaround for this
is to run the configure script with the --disable-asm argument, so that
the assembler-language routines are not used. The macosx-setup.sh will
configure libgcrypt with that option.
PortAudio - when compiling on 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 on Snow Leopard.
Newer versions don't have this problem, but still fail to build on Lion
if a universal build is attempted. The macosx-setup.sh script downloads
a newer version, and also suppresses the universal build.
GeoIP - Their man pages "helpfully" have an ISO 8859-1 copyright symbol
in the copyright notice, but OS X's default character encoding is UTF-8.
sed on Mountain Lion barfs at the "illegal character sequence"
represented by an ISO 8859-1 copyright symbol, as it's not a valid UTF-8
sequence. The macosx-setup.sh script uses iconv to convert the man page
files from ISO 8859-1 to UTF-8.
