How to build the sources from CVS
|
||
------------------------------------------------------------------------
|
||
|
||
I) Windows using plain makefiles
|
||
----------------------------------------
|
||
|
||
a) If using Microsoft Visual C++ 5.0 or 6.0
|
||
|
||
Ensure that the command-line compiler and tools (including
|
||
nmake) are installed and ready to run. Depending on your
|
||
installation there may be a batch file (named something like
|
||
VCVARS32.BAT) that needs to be run to set correct environment
|
||
varaibles and PATH entries.
|
||
|
||
Continue with item c) below.
|
||
|
||
|
||
b) If using the GNU MinGW32 or GNU CygWin32 compilers
|
||
|
||
You'll need the compiler itself which is available from
|
||
|
||
http://www.cygwin.com
|
||
|
||
When using MingW32 you'll need GNU make which is a part
|
||
of the CygWin32 toolchain and is also available as a stand
|
||
alone port without the infamous Cygwin.dll from
|
||
|
||
http://agnes.dida.physik.uni-essen.de/~janjaap/mingw32
|
||
|
||
The makefile has small problems with Cygwin´s tools
|
||
so it is recommended not to use these (but MingGW32
|
||
and its make.exe).
|
||
|
||
-> Set your path so that it includes the directory
|
||
where your compiler and tools reside
|
||
|
||
b-2) Using Mingw32 with gcc-2.95 and Anders Norlander's
|
||
Win32 headers
|
||
|
||
Using the newer gcc-2.95/Noralander header combination
|
||
will allow you to compile more of the MSW code, such
|
||
as OLE and Drag-n-Drop.
|
||
|
||
Instructions are similar to those for Regular Mingw32 except
|
||
|
||
->Get the compiler from
|
||
ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32/gcc-2.95/
|
||
|
||
->patch the gcc headers with info in wxWin\Mingw32-gcc295.patches.
|
||
PLEASE APPLY THESE PATCHES BY HAND! There are apparently a few
|
||
different versions of the headers floating around.
|
||
|
||
->Edit wx/src/makeg95.env and set the MINGW32 variable at the top of
|
||
the file to either 1 (you have Mingw32) or 0 (you have Cygwin32).
|
||
If using MINGW32, also set the MINGW32VERSION variable
|
||
appropriately.
|
||
|
||
|
||
c) Build instructions
|
||
|
||
-> Assumming that you installed the wxWindows sources
|
||
into c:\wxWin
|
||
-> Copy c:\wxWin\include\wx\msw\setup0.h
|
||
to c:\wxWin\include\wx\msw\setup.h
|
||
-> Edit c:\wxWin\include\wx\msw\setup.h so that
|
||
most features are enabled (i.e. defined to 1) with
|
||
#define wxUSE_ODBC 0
|
||
#define wxUSE_SOCKETS 0
|
||
#define wxUSE_HTML 1
|
||
#define wxUSE_THREADS 1
|
||
#define wxUSE_FS_INET 0
|
||
#define wxUSE_FS_ZIP 1
|
||
#define wxUSE_BUSYINFO 1
|
||
#define wxUSE_DYNLIB_CLASS 1
|
||
#define wxUSE_ZIPSTREAM 1
|
||
#define wxUSE_LIBJPEG 1
|
||
#define wxUSE_LIBPNG 1
|
||
|
||
and iostreams ares disabled with
|
||
#define wxUSE_STD_IOSTREAM 0
|
||
|
||
note: ODBC and SOCKETS can be 1 for gcc-2.95
|
||
|
||
-> type: cd c:\wxWin\src\msw
|
||
-> type: make -f makefile.g95 (if using GNU tools)
|
||
or type: make -f makefile.vc (if using MS VC++)
|
||
|
||
|
||
II) Unix ports
|
||
--------------
|
||
|
||
Building wxGTK or wxMotif completely without configure
|
||
won't ever work, but there is now a new makefile system
|
||
that works without libtool and automake, using only
|
||
configure to create what is needed.
|
||
|
||
In order to create configure, you need to have the
|
||
GNU autoconf package (version 2.13 or 2.14) installed
|
||
on your system and type run "autoconf" in the base
|
||
directory (or run the autogen.sh script in the same
|
||
directory, which just calls autoconf).
|
||
|
||
Set WXWIN environment variable to the base directory such
|
||
as ~/wxWindows (this is actually not really needed).
|
||
|
||
-> type: export WXWIN=~/wxWindows
|
||
-> type: md mybuild
|
||
-> type: cd mybuild
|
||
-> type: ../configure --with-motif
|
||
or type: ../configure --with-gtk
|
||
-> type: make
|
||
-> type: su <type root password>
|
||
-> type: make install
|
||
-> type: ldconfig
|
||
-> type: exit
|
||
|
||
Call configure with --disable-shared to create a static
|
||
library. Calling "make uninstall" will remove the installed
|
||
library and "make dist" will create a distribution (not
|
||
yet complete).
|
||
|
||
III) Windows using configure
|
||
----------------------------------------
|
||
|
||
Take a look at Unix->Windows cross compiling. With minor
|
||
modifications, this should work in Windows if you've got the cygnus
|
||
utilities (bash, GNU make, etc) and either mingw32 or cygwin32 installed.
|
||
See http://www.cygnus.com for these programs, or go straight to their
|
||
ftp server at ftp://sourceware.cygnus.com/pub/cygwin/.
|
||
|
||
Of course, you can also build the library using plain makefiles (see
|
||
section I).
|
||
|
||
V) MacOS
|
||
----------------------------------------
|
||
|
||
VI) OS/2
|
||
----------------------------------------
|
||
|
||
VII) Unix->Windows cross-compiling using configure
|
||
--------------------------------------------------
|
||
|
||
First you'll need a cross-compiler; linux glibc binaries of mingw32 and
|
||
cygwin32 (both based on egcs) can be found at
|
||
ftp://ftp.objsw.com/pub/crossgcc/linux-x-win32. Otherwise you can
|
||
compile one yourself. Check the relevant FAQs.
|
||
|
||
[ A Note about cygwin32 and mingw32: the main difference is that cygwin32
|
||
binaries are always linked against cygwin.dll. This dll encapsulates most
|
||
standard Unix C extensions, which is very handy if you're porting unix
|
||
software to windows. However, wxMSW doesn't need this, so mingw32 is
|
||
preferable if you write portable C(++). ]
|
||
|
||
You might want to build both Unix and Windows binaries in the same source
|
||
tree; to do this make subdirs for each e.g. unix and win32. If you've
|
||
already build wxWindows in the main dir, do a 'make distclean' there,
|
||
otherwise configure will get confused. (In any case, read the section 'Unix
|
||
using configure' and make sure you're able to build a native wxWindows
|
||
library; cross-compiling errors can be pretty obscure and you'll want to be
|
||
sure that your configure setup is basically sound.)
|
||
|
||
To cross compile the windows library, do
|
||
-> cd win32
|
||
(or whatever you called it)
|
||
Now run configure. There are two ways to do this
|
||
-> ../configure --host=i586-mingw32 --build=i586-linux --with-mingw \
|
||
--enable-dnd=no --without-odbc
|
||
where --build= should read whatever platform you're building on. Configure
|
||
will notice that build and host platforms differ, and automatically prepend
|
||
i586-mingw32- to gcc, ar, ld, etc (make sure they're in the PATH!).
|
||
The other way to run configure is by specifying the names of the binaries
|
||
yourself:
|
||
-> CC=i586-mingw32-gcc CXX=i586-mingw32-g++ RANLIB=i586-mingw32-ranlib \
|
||
DLLTOOL=i586-mingw32-dlltool LD=i586-mingw32-ld NM=i586-mingw32-nm \
|
||
../configure --host=i586-mingw32 --with-mingw --enable-dnd=no
|
||
|
||
(all assuming you're using mingw32)
|
||
Drag'n'drop is disabled because mingw32 lacks (AFAIK) OLE headers.
|
||
|
||
[ Update: some new mingw32 versions now have a new set of windows header
|
||
files, which apparently can handle ole. Untested at the moment ]
|
||
|
||
ODBC files don't compile as of 13.10.99 - may be this will be fixed by the
|
||
moment you're reading these lines.
|
||
|
||
Configure will conclude that shared libraries are out of the question and
|
||
opt for a static one. I haven't looked into DLL creation yet.
|
||
|
||
Type
|
||
-> make
|
||
and wait, wait, wait. Don't leave the room, because the minute you do there
|
||
will be a compile error :-)
|
||
|
||
NB: you risk to get quite a few warnings about "ANSI C++ forbids implicit
|
||
conversion from 'void *'" in all places where va_arg macro is used. This
|
||
is due to a bug in (some versions of) mingw32 headers which may be
|
||
corrected by editing the file
|
||
|
||
${install_prefix}/lib/gcc-lib/i586-mingw32/egcs-2.91.57/include/stdarg.h
|
||
|
||
(instead of egcs-2.91.57 you may have something different), searching for
|
||
the lines
|
||
|
||
/* Define __gnuc_va_list. */
|
||
|
||
#ifndef __GNUC_VA_LIST
|
||
#define __GNUC_VA_LIST
|
||
#if defined(__svr4__) || defined(_AIX) || defined(_M_UNIX) || defined(__NetBSD__)
|
||
typedef char *__gnuc_va_list;
|
||
#else
|
||
typedef void *__gnuc_va_list;
|
||
#endif
|
||
#endif
|
||
|
||
and adding "|| defined(_WIN32)" to the list of platforms on which
|
||
__gnuc_va_list is char *.
|
||
|
||
If this is successful, you end up with a libwx_msw.a in win32/lib. Now try
|
||
building the minimal sample:
|
||
|
||
-> cd samples/minimal
|
||
-> make
|
||
|
||
and run it with wine, for example (or copy to a Windows box)
|
||
-> wine minimal.exe
|
||
|
||
If all is well, do an install; from win32
|
||
-> make install
|
||
|
||
Native and cross-compiled installations can co-exist peacefully
|
||
(as long as their widget sets differ), except for wx-config. You might
|
||
want to rename the cross-compiled one to i586-mingw32-wx-config, or something.
|
||
|
||
Cross-compiling TODO:
|
||
---------------------
|
||
- resource compiling must be done manually for now (should/can we link the
|
||
default wx resources into libwx_msw.a?) [ No we can't; the linker won't
|
||
link it in... you have to supply an object file ]
|
||
- dynamic libraries
|
||
- static executables are HUGE -- there must be room for improvement.
