4.3. GNU compiler toolchain (UNIX or Win32

Cygwin)

4.3.1. gcc (GNU compiler collection)

Win32: Warn!

Using Cygwin gcc to compile Wireshark is "EXPERT ONLY" and therefore NOT re-

commended. If you really want to try it anyway, see: http://wiki.wireshark.org/Devel-

opment/CygwinGCC for some details!

The GCC C compiler is available for most of the UNIX-like platforms and as the Devel/gcc package

from the Cygwin setup.

If GCC isn't already installed or available as a package for your platform, you can get it at: http://

gcc.gnu.org/.

After correct installation, typing at the bash command line prompt:

$ gcc --version

should result in something like:

gcc (GCC) 3.4.4 (cygwin special) (gdc 0.12, using dmd 0.125)

4.3.2. gdb (GNU project debugger)

GDB is the debugger for the GCC compiler. It is available for many (if not all) UNIX-like platforms

and as the Devel/gdb package from the Cygwin setup

If you don't like debugging using the command line, there are some GUI frontends for it available,

most notably GNU DDD.

If gdb isn't already installed or available as a package for your platform, you can get it at: http://

www.gnu.org/software/gdb/gdb.html.

After correct installation:

$ gdb --version

should result in something like:

GNU gdb 6.5.50.20060706-cvs (cygwin-special)
