============================================================
1. Regenerating makefiles
-------------------------
-wxWindows now uses Bakefile (http://bakefile.sourceforge.net) to generate
+wxWidgets now uses Bakefile (http://bakefile.sourceforge.net) to generate
native makefiles. You must have bakefile installed if you want to regenerate
the makefiles. Bakefile currently runs on Unix and Windows systems. You will
need Python >= 2.2 installed on Unix and either use Bakefile installer or have
regenerate all outdated makefiles. See $(wx)/build/bakefiles/README for more
details.
-Note that it generates makefiles for samples and contrib libraries, too.

-IMPORTANT NOTE: Don't forget to run autoconf in wxWindows root directory if
- you changed any conditional variable or target condition
- in .bkl files! You will know that this happened if
- $(wx)/autoconf_inc.m4 content changed.

+ (after running Bakefile) if you changed any conditional
+ variable or target condition in .bkl files! You will know that

You can use Bakefile to generate makefiles or projects customized to your
needs, too. See Bakefiles.bkgen for details on bakefile commands used to
-DDEBUG_INFO=default -DDEBUG_FLAG=default
-DOFFICIAL_BUILD=0 -DUSE_HTML=0 -DUSE_OPENGL=0 -DUSE_ODBC=0
-DMONOLITHIC=1 -DUSE_GUI=0 wx.bkl
+It is, however, recommended to modify Bakefiles.bkgen (or
+Bakefiles.local.bkgen) by means of <add-flags> and <del-flags> directives
+and use bakefile_gen instead of running bakefile directly.
2. Bakefile files organization
------------------------------
-Makefile are generated from .bkl files ("bakefiles") from three places:
+Makefile are generated from .bkl files ("bakefiles") from two places:
- $(wx)/build/bakefiles directory
- - $(wx)/contrib/build/* directories
- samples directories
$(wx)/build/bakefiles contains bakefiles for main library and support files
-that simplify writing bakefiles for contrib and samples.
+that simplify writing bakefiles for samples.
Support files are:
wxwin.py - helper functions
common.bkl
common_samples.bkl
- common_contrib.bkl - shared definitions and templates
config.bkl - user-configurable build options
make_dist.mk - implementation of "make dist" on Unix
organized into variables for toolkits, platforms and libraries. The variables
come in pairs: there's always FOO_SRC for source files and FOO_HDR for header
files. Platform or toolkit specific files are grouped together in variable
-with platform or tookit name in them, e.g. BASE_WIN32_SRC, BASE_UNIX_SRC,
+with platform or toolkit name in them, e.g. BASE_WIN32_SRC, BASE_UNIX_SRC,
GTK_SRC, MOTIF_SRC.
Note: A side effect of this toolkit-centric organization is that one file may
- be present several times in files.bkl in different contenxt.
+ be present several times in files.bkl in different contexts.
When you are adding a file, you must put it into appropriate variable. This is
easy if you are adding the file to library that is always built from same
Make sure to add <wx-lib> statements for all libraries from multilib build
that are required by the sample.
-Run Python script regenMakefile.py in $(wx)/build/bakefiles to update Makefile
-then run "make" in $(wx)/build/bakefiles directories.
+The Windows resource specification should use the central .rc file:
-Finally commit $(wx)/build/bakefiles/Makefile and all the other modified files.
+ <win32-res>../sample.rc</win32-res>
+Run bakefile_gen in $(wx)/build/bakefiles to regenerate the bakefiles.
-5. Adding contrib library
--------------------------
-
-Contrib library bakefiles are located in $(wx)/contrib/build/name-of-contrib
-directory, together with generated makefiles. Copy the bakefile from another
-contrib library, change the IDs and files accordingly. Note that there must be
-two targets for contrib wxFoo: foodll and foolib.
-
-foodll definition must contain <wx-lib> statements for all libraries it
-depends on. WXUSINGDLL and WXMAKINGDLL_FOO must be defined and symbols from
-the library should use WXDLLIMPEXP_FOO defined in wxFoo's headers analogically
-to WXDLLIMPEXP_{BASE,CORE,HTML,...} in the main library (see 5g below for
-additional details).
+Finally commit $(wx)/build/bakefiles/make_dist.mk and all the other modified files.
-Run Python script regenMakefile.py in $(wx)/build/bakefiles to update Makefile
-and commit $(wx)/build/bakefiles/Makefile.
+Currently we commit the generated makefiles except .dms, .vcp.
-6. Adding new core library
+5. Adding new core library
--------------------------
When adding new library to the core set of libraries, the files must be
Finally, define FOO_SRC and FOO_HDR to contain both
FOO_PLATFORM_{SRC,HDR} and FOO_{SRC,HDR} (see NET_SRC definition for an
example).
- * Add FOO_HDR to ALL_GUI_HEADERS or ALL_BASE_HEADERS.
+ * Add FOO_HDR to ALL_GUI_HEADERS or ALL_BASE_HEADERS.
* If wxFoo is wxBase library (doesn't use GUI), add FOO_SRC to
ALL_BASE_SOURCES.
b) Modify bakefile system in build/bakefiles/ to recognize wxFoo:
* Add 'foo' to MAIN_LIBS and LIBS_NOGUI or LIBS_GUI (depending on whether
the library depends on wxCore or not) to wxwin.py file.
- * Add the library to DEPS_TABLE in wxwin.py
+ * Add extra libraries needed by wxFoo (if any) to EXTRALIBS in wxwin.py
* Add WXLIB_FOO definition to common.bkl (into the "Names of component
libraries" section). It looks like this:
<set var="WXLIB_FOO">
<if cond="MONOLITHIC=='0'">$(mk.evalExpr(wxwin.mkLibName('foo')))</if>
</set>
-c) Add files to monolithic build: it's enough to add FOO_SRC to MONOLIB_GUI_SRC
- or MONOLIB_SRC, depending on whether wxFoo uses GUI or not.
+c) Modify monolithic.bkl to add files to monolithic build: it's enough to add
+ FOO_SRC to MONOLIB_GUI_SRC or MONOLIB_SRC, depending on whether wxFoo uses
+ GUI or not.
-d) Add files to multilib build: add foolib and foodll targets. Don't use
- wxBase targets as the template, use e.g. wxXML or wxHTML. Make sure
- WXMAKINGDLL_FOO is defined in foodll.
+d) Modify multilib.bkl to add files to multilib build: add foolib and foodll
+ targets. Don't use wxBase targets as the template, use e.g. wxXML or wxHTML.
+ Make sure WXMAKINGDLL_FOO is defined in foodll.
e) Regenerate all makefiles (don't forget to run autoconf)
f) Update configure.in and wx-config.in to contain information about
the library and needed linker flags:
- * Add "foo" to either CORE_BASE_LIBS or CORE_GUI_LIBS in configure.in so
- that wxFoo is not treated as contrib library in monolithic build.
- * If wxFoo links against additional libraries, add neccessary linker
+ * Add "foo" to either STD_BASE_LIBS or STD_GUI_LIBS in configure.in.
+ * If wxFoo links against additional libraries, add necessary linker
flags and libraries to ldflags_foo and ldlibs_foo variables in
wx-config.in (both are optional).
#define WXDLLIMPEXP_NET
#define WXDLLIMPEXP_DATA_NET(type) type
#endif
+ Don't forget to add WXDLLIMPEXP_FWD_FOO definitions too.
Use WXDLLIMPEXP_FOO when declaring wxFoo classes and functions.
h) Add this code to one of wxFoo's files (the more often used, the better):
WX_CHECK_BUILD_OPTIONS("wxFoo")
i) Add information about wxFoo to the manual ("Libraries list" section
- in libs.tex).
+ in libs.tex) and update docs/latex/wx/libs.dia (you need Dia for this)
+ to show the dependencies of the new library.
+j) Also please add 4 #pragma comment(lib, "foo") (for Unicode/ANSI
+ Release/Debug combinations) to the file include/msvc/wx/setup.h and
+ add a check for WXMAKINGDLL_FOO to the test whether we're building a DLL at
+ the end of include/wx/msw/chkconf.h.
