Notice
|
|
|
|
The CMake build system for Wireshark is not yet ready for
|
|
building the whole system. You'll still need autofoo to buld it.
|
|
The only thing that can be build is dumpcap, and even that one
|
|
requires that you successfully ran autofoo prior to running cmake
|
|
(e.g. config.h is not yet build, lex and yacc are not run).
|
|
Basically this is an experiment and if we find out that it works
|
|
and we like cmake more than autofoo we might switch one day.

How to get started with cmake?
|
|
==============================
|
|
|
|
You can find documentation on cmake at: http://www.cmake.org/
|
|
|
|
cmake is designed to support out of tree builds. So much so, that
|
|
in tree builds do not work properly in all cases.
|
|
|
|
How to do out of tree build (Unix/Linux):
|
|
1) Install cmake.
|
|
2) Build the project with the old build system once (to generate
|
|
config.h and run bison and flex to generate some c-files).
|
|
3) Assuming, you are in the top directory of the wireshark source
|
|
cd ..
|
|
4) mkdir build
|
|
5) cd build
|
|
6) cmake ../<Name_of_WS_source_dir>
|
|
7) make
|
|
|
|
Why cmake?
|
|
==========
|
|
- Can create project files for some MS and Apple IDEs.
|
|
- Fast
|
|
- Easier to understand/learn
|
|
- One build infrastructure even including Windows?
|
|
...
|
|
|
|
Why not cmake?
|
|
==============
|
|
- Lots of work to do
|
|
- Everyone who wants to build from source needs cmake
|
|
- Current state of documentation isn't really better than
|
|
autofoo documentation, in some respect it's even worse
|
|
(you need to buy a book to get an explanation as to how
|
|
cmake really works).
|
|
...
|
|
|
|
What needs to be done?
|
|
======================
|
|
|
|
only dumpcap and libwiretap have been done, and even those rely on
|
|
autofoo having been run before:
|
|
|
|
- Add proper GTK1/GLIB2/GLIB1 detection (currently links against gtk2
|
|
to pull in glib2).
|
|
- Create config.h
|
|
- Autocreated source files in wiretap need to be build from .l, .y files.
|
|
|
|
All other tools and libs still need to be built.
