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 recommended. If you really want to try it anyway, see: for some details!

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

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

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)

However, the version string may vary.

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

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: .

After correct installation:

$ gdb --version

should result in something like:

GNU gdb 6.5.50.20060706-cvs (cygwin-special)

This GDB was configured as "i686-pc-cygwin".
      

However, the version string may vary.

4.3.3. ddd (GNU Data Display Debugger)

The GNU Data Display Debugger is a good GUI frontend for GDB (and a lot of other command line debuggers), so you have to install GDB first. It is available for many UNIX-like platforms and as the ddd package from the .

If GNU DDD isn't already installed or available as a package for your platform, you can get it at: .

4.3.4. make (GNU Make)

	Win32 Note!
	Although some effort is made to use make from the Cygwin environment, the mainline is still using Microsoft Visual Studio's nmake.

GNU Make is available for most of the UNIX-like platforms and also as the Devel/make package from the .

If GNU Make isn't already installed or available as a package for your platform, you can get it at: .

After correct installation:

$ make --version

should result in something like:

GNU Make 3.81
