-Supporting many different platforms can be a difficult challenge. The challenge for wxWidgets is especially great, because it supports a variety of different compilers and development environments, including MSVC, Borland C++, MinGW, DevCPP, GNU make/automake, among others. Maintaining such a large number of different project files and formats can quickly become overwhelming. To simplify the maintenance of these formats, one of the wxWidgets developers, Vaclav Slavik, created Bakefile, a XML-based makefile wrapper that generates all the native project files for wxWidgets. So now, even though wxWidgets supports all these formats, wxWidgets developers need only update one file - the Bakefile, and it handles the rest. But Bakefile isn't specific to wxWidgets in any way - you can use Bakefile for your own projects, too. This brief tutorial will take a look at how to do that.
-
-Note that this tutorial assumes that you are familiar with how to build software using one of the supported Bakefile makefile systems, that you have some basic familiarity with how makefiles work, and that you are capable of setting environment variables on your platform. Also note that the terms Unix and Unix-based refers to all operating systems that share a Unix heritage, including FreeBSD, Linux, Mac OS X, and various other operating systems.

-- Getting Started --
-First, you'll need to install Bakefile. You can always find the latest version for download online at http://bakefile.sf.net. A binary installer is provided for Windows users, while users of Unix-based operating systems (OS) will need to unpack the tarball and run configure && make && make install. (Packages for some distros are also available, check http://bakefile.sf.net for details.)

-- Setting Up Your wx Build Environment --
-Before you can build wxWidgets software using Bakefile or any other build system, you need to make sure that wxWidgets is built and that wxWidgets projects can find the wxWidgets includes and library files. wxWidgets build instructions can be found by going to the docs subfolder, then looking for the subfolder that corresponds to your platform (i.e. msw, gtk, mac) and reading "install.txt" there. Once you've done that, here are some extra steps you should take to make sure your Bakefile projects work with wxWidgets:

On Windows
----------
-Once you've built wxWidgets, you should create an environment variable named WXWIN and set it to the home folder of your wxWidgets source tree. (If you use the command line to build, you can also set or override WXWIN at build time by passing it in as an option to your makefile.)

On Unix
-------
-In a standard install, you need not do anything so long as wx-config is on your PATH. wx-config is all you need. (See the section of the book on using wx-config for more information.)

-- A Sample wx Project Bakefile --
-Now that everything is setup, it's time to take Bakefile for a test run. I recommend that you use the wx sample Bakefile to get you started. It can be found in the 'build/bakefiles/wxpresets/sample' directory in the wxWidgets source tree. Here is the minimal.bkl Bakefile used in the sample:

On Windows:
bakefile -f msvc -I.. minimal.bkl
On Unix:
bakefile -f gnu -I.. minimal.bkl
-It should generate a makefile (makefile.vc or GNUmakefile, respectively) which you can use to build the software. Just build the software using the command "nmake -f makefile.vc" or "make -f GNUmakefile" respectively. Now let's take a look at some of the basic Bakefile concepts that you'll need to know to move on from here.

gnu GNU toolchain makefiles (Unix)
TIP: autoconf Project Type
---------------------------
-You may notice that in the sample folder, there is also a file called configure.in. That file is the input for autoconf, which creates the configure scripts that you often see when you build software from source on Unix-based platforms. People use configure scripts because they make your Unix makefiles more portable by automatically detecting the right libraries and commands to use on the user's machine and OS. This is necessary because there are many Unix-based operating systems and they all are slightly different in various small ways.
-
-Bakefile does not generate a configure or configure.in script, so if you want to use configure scripts with your Unix-based software, you will need to learn how to use autoconf. Unfortunately, this topic deserves a book all its own and is beyond the scope of this tutorial, but a book on the subject can be found online at: http://sources.redhat.com/autobook/. Note that you do not need to use automake when you are using Bakefile, just autoconf, as Bakefile essentially does the same thing as automake.

-- Targets --
-Every project needs to have a target or targets, specifying what is to be built. In Bakefile, you specify the target by creating a tag named with the target type. The possible names for targets are:

-- Adding Sources and Includes --
-Obviously, you need to be able to add source and include files to your project. You add sources using the "<sources>" tag (as shown above), and add include directories using the "<include>" tag. You can add multiple <sources> and <include> tags to add multiple source files, or you can also add multiple sources and includes into one tag by separating them with a space, like so:

-If your sources are in a subfolder of your Bakefile, you use the slash "/" character to denote directories, even on Windows. (i.e. src/minimal.cpp) For more options and flags, please consult the Bakefile documentation in the 'doc' subfolder of Bakefile, or you can also find it on the Bakefile web site.

-- Build Options --
-What if you want to offer a DEBUG and a RELEASE build? Or a UNICODE/ANSI build? You can do this in Bakefile by creating options. To create an option, use the "<option>" tag. A typical option has three important parts: a name, a default value, and a comma-separated list of values. For example, here is how to create a DEBUG option which builds debug by default:

</option>
-You can then test the value of this option and conditionally set build settings, flags, etc. For more information on both options and conditional statements, please refer to the Bakefile documentation.

-- Bakefile Presets/Templates and Includes --
-It is common that most projects will reuse certain settings, or options, in their makefiles. (i.e. DEBUG or static/dynamic library options) Also, it is common to have to use settings from another project; for example, any project that uses wxWidgets will need to build using the same flags and options that wxWidgets was built with. Bakefile makes these things easier by allowing users to create Bakefile templates, where you can store common settings.
-
-Bakefile ships with a couple of templates, found in the 'presets' subfolder of your Bakefile installation. The "simple.bkl" template adds a DEBUG option to makefiles so you can build in release or debug mode. To add this template to your project, simply add the tag "<include file="presets/simple.bkl"/>" to the top of your Bakefile. Then, when creating your target, add the "template="simple"" attribute to it. Now, once you build the makefile, your users can write commands like:

In order to build the software in debug mode.
-To simplify the building of wxWidgets-based projects, wxWidgets contains a a set of Bakefiles that automatically configure your build system to be compatible with wxWidgets. As you'll notice in the sample above, the sample project uses the wx template. Once you've included the template, your software will now build with wxWidgets support.

+
+There's also "wxconsole" template for building console-based wxWidgets applications
+and "wx" template that doesn't specify application type (GUI or console) and can be
+used e.g. for building libraries that use wxWidgets.
-But since the wx presets don't exist in the Bakefile presets subfolder, Bakefile needs to know where to find these presets. The "-I" command adds the wxpresets folder to Bakefile's search path.

-If you regularly include Bakefile presets in places other than the Bakefile presets folder, then you can set the BAKEFILE_PATHS environment variable so that Bakefile can find these Bakefiles and include them in your project. This way you no longer need to specify the -I flag each time you build.

-- bakefile_gen - Automated Bakefile Scripts --
-If you have a large project, you can imagine that the calls to Bakefile would get more and more complex and unwieldly to manage. For this reason, a script called bakefile_gen was created, which reads in a .bkgen file that provides all the commands needed to build all the makefiles your project supports. A discussion of how to use bakefile_gen is beyond the scope of this tutorial, but it deserves mention because it can be invaluable to large projects. Documentation on bakefile_gen can be found in the Bakefile documentation.
