============================================================
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
Python on Windows.
Once you have installed Bakefile, you can easily regenerate the makefiles using
-the makefile in $(wx)/build/bakefiles directory. The makefile uses Unix make
-syntax and works on Unix or using either Borland Make or GNU Make (including
-native Win32 port called mingw32-make from http://www.mingw.org) on Windows.
-It is possible that other Windows make utilities work as well, but it wasn't
-tested. "make clean" only works on Unix or Cygwin or MSYS emulation layer on
-Windows.
-
-You can use following commands when generating the makefiles (must be run from
-$(wx)/build/bakefiles directory):
-
-make <filename> generates one makefile (e.g. "make ../makefile.gcc")
-make all regenerates all makefiles that are out of date
-make library only makefiles for the main library
-make <compiler> only makefiles for given compiler; possible values
- are "borland", "watcom", "mingw", "autoconf", "msvc"
- and "mvsc6prj" (Visual C++ project files)
-make clean deletes all generated files (Unix shell only)
-
-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.

+needs, too. See Bakefiles.bkgen for details on bakefile commands used to
+generate makefiles. For example, you can use this command to generate
+VC++ project files without wxUniversal configurations:
bakefile -v -fmsvc6prj -o../wxmy.dsw -DRUNTIME_LIBS=dynamic
+ -DDEBUG_INFO=default -DDEBUG_FLAG=default
-DOFFICIAL_BUILD=0 -DUSE_HTML=1 -DUSE_OPENGL=1
-DMONOLITHIC=0 -DUSE_GUI=1 -DWXUNIV=0 wx.bkl
Or monolithic instead of multilib (the default):
bakefile -v -fmsvc6prj -o../wxmono.dsw -DRUNTIME_LIBS=dynamic
+ -DDEBUG_INFO=default -DDEBUG_FLAG=default
-DOFFICIAL_BUILD=0 -DUSE_HTML=1 -DUSE_OPENGL=1
-DMONOLITHIC=1 -DUSE_GUI=1 wx.bkl
Or monolithic wxBase:
bakefile -v -fmsvc6prj -o../wxBase.dsw -DRUNTIME_LIBS=dynamic
+ -DDEBUG_INFO=default -DDEBUG_FLAG=default
-DOFFICIAL_BUILD=0 -DUSE_HTML=0 -DUSE_OPENGL=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
Files used to build the library are:
wx.bkl - main file
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
-and commit $(wx)/build/bakefiles/Makefile.
+The Windows resource specification should use the central .rc file:
+ <win32-res>../sample.rc</win32-res>
-5. Adding contrib library
--------------------------
+Run bakefile_gen in $(wx)/build/bakefiles to regenerate the bakefiles.
-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.
+Finally commit $(wx)/build/bakefiles/make_dist.mk and all the other modified files.
-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).
+Currently we commit the generated makefiles except .dms, .vcp.
-Run Python script regenMakefile.py in $(wx)/build/bakefiles to update Makefile
-and commit $(wx)/build/bakefiles/Makefile.

-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_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.
(You can apply different approaches to HDR and SRC variables, if e.g.
headers are all common but sources are not.)
native make tools.
b) Modify bakefile system in build/bakefiles/ to recognize wxFoo:
- * Add 'foo'to MAIN_LIBS and LIBS_NOGUI or LIBS_GUI (depending on whether
+ * 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 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 wx-config.in to contain information about the library and needed
- linker flags:
- * Add "foo" to either CORE_BASE_LIBS or CORE_GUI_LIBS so that wxFoo is
- not treated as contrib library in monolithic build.
- * If wxFoo links against additional libraries, add neccessary linker
- flags and libraries to ldflags_foo and ldlibs_foo variables (both are
- optional).
-
-g) Update defs.h to define WXMAKINGDLL_FOO if WXMAKINGDLL is defined (add
- #define WXMAKINGDLL_FOO inside first "#ifdef WXMAKINGDLL" block in defs.h)
- and to define WXDLLIMPEXP_FOO and WXDLLIMPEXP_DATA_FOO. You can copy
- e.g. WXDLLIMPEXP_NET definition, it is something like this:
+f) Update configure.in and wx-config.in to contain information about
+ the library and needed linker flags:
+ * 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).
+
+g) Update dlimpexp.h to define WXMAKINGDLL_FOO if WXMAKINGDLL is defined (add
+ #define WXMAKINGDLL_FOO inside first "#ifdef WXMAKINGDLL" block in
+ dlimpexp.h) and to define WXDLLIMPEXP_FOO and WXDLLIMPEXP_DATA_FOO. You
+ can copy e.g. WXDLLIMPEXP_NET definition, it is something like this:
#ifdef WXMAKINGDLL_NET
#define WXDLLIMPEXP_NET WXEXPORT
#define WXDLLIMPEXP_DATA_NET(type) WXEXPORT type
#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.
-i) Add information about wxFoo to the manual
- FIXME - where exactly
+h) Add this code to one of wxFoo's files (the more often used, the better):
+ // DLL options compatibility check:
+ #include "wx/app.h"
+ WX_CHECK_BUILD_OPTIONS("wxFoo")
+
+i) Add information about wxFoo to the manual ("Libraries list" section
+ 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.
