== Building Wireshark
=== I have libpcap installed; why did the configure script not find pcap.h or bpf.h?
=== Why does building Wireshark fail due to missing headers (.h files)?
Are you sure pcap.h and bpf.h are installed? The official
distribution of libpcap only installs the libpcap.a library file when
"make install" is run. To install pcap.h and bpf.h, you must run "make
install-incl". If you're running Debian or Redhat, make sure you have
the "libpcap-dev" or "libpcap-devel" packages installed.
If this is happening on Linux, it's likely due to missing development library packages.
For example, Debian and Ubuntu ship the GLib library in the libglib2.0-0 package, but ship its header files and other development assets in the libglib2.0-dev package.
It's also possible that pcap.h and bpf.h have been installed in a
strange location. If this is the case, you may have to tweak aclocal.m4.
== Starting Wireshark
=== When I try to run Wireshark, why does it complain about `sprint_realloc_objid` being undefined?
Wireshark can only be linked with version 4.2.2 or later of UCD SNMP.
Your version of Wireshark was dynamically linked with such a version of
UCD SNMP; however, you have an older version of UCD SNMP installed,
which means that when Wireshark is run, it tries to link to the older
version, and fails. You will have to replace that version of UCD SNMP
with version 4.2.2 or a later version.
=== I've installed Wireshark from Fink on macOS; why is it very slow to start up?
When an application is installed on macOS, prior to 10.4, it is
usually "prebound" to speed up launching the application. (That's what
the "Optimizing" phase of installation is.)
Fink normally performs prebinding automatically when you install a
package. However, in some rare cases, for whatever reason the prebinding
caches get corrupt, and then not only does prebinding fail, but startup
actually becomes much slower, because the system tries in vain to
perform prebinding "on the fly" as you launch the application. This
fails, causing sometimes huge delays.
To fix the prebinding caches, run the command
----
$ sudo /sw/var/lib/fink/prebound/update-package-prebinding.pl -f
----
We maintain setup scripts (_*-setup.sh_) for many major distributions in the _tools_ directory of the Wireshark sources that can install the required development packages for you.
== Crashes and other fatal errors
=== I have an XXX network card on my machine; if I try to capture on it, why does my machine crash or reset itself?
=== I have an _XXX_ network card on my machine; if I try to capture on it, why does my machine crash or reset itself?
