   2                 How to build the sources from CVS
   3 ------------------------------------------------------------------------
   4
   5 Please use the install.txt files in docs/gtk, docs/msw, docs/motif, docs/mac
   6 etc. alongside these instructions.
   7
   8 I) Windows using plain makefiles
   9 ----------------------------------------
  10
  11 a) If using Microsoft Visual C++ 5.0 or 6.0
  12
  13 Ensure that the command-line compiler and tools (including
  14 nmake) are installed and ready to run.  Depending on your
  15 installation there may be a batch file (commonly named VCVARS32.BAT)
  16 that needs to be run to set correct environment variables and PATH entries.
  17
  18 Continue with item c) below.
  19
  20
  21 b) If using the MinGW or Cygwin compilers
  22
  23 You can get MinGW from  http://www.mingw.org/
  24
  25 Cygwin is available at  http://www.cygwin.com/
  26
  27 If you are using Cygwin or MinGW together with the MSYS environment, you
  28 can build the library using configure (see "Unix ports" and
  29 "Windows using configure" below). You can also
  30 build wxWidgets without configure using native makefile, but only with
  31 MinGW. Using Cygwin together with Windows makefile is no longer supported.
  32
  33 If building with MinGW without configure:
  34
  35 -> Set your path so that it includes the directory
  36    where your compiler and tools reside
  37
  38 -> Make sure you have GNU Make installed. It must be Windows native version.
  39    Download it from http://www.mingw.org, the executable will be called
  40    mingw32-make.exe.
  41
  42 -> Modern version of MinGW is required; preferably MinGW 2.0 (with gcc3),
  43    but MinGW with gcc-2.95.3 will suffice. If you are using 2.95, you will
  44    have to change variable GCC_VERSION in config.gcc (see msw/install.txt
  45    for details).
  46
  47 If using configure, Unix instructions apply.
  48
  49
  50 c) Build instructions
  51
  52 Assumming that you installed the wxWidgets sources
  53 into c:\wxWidgets:
  54
  55 -> Copy c:\wxWidgets\include\wx\msw\setup0.h
  56    to   c:\wxWidgets\include\wx\msw\setup.h
  57 -> Edit c:\wxWidgets\include\wx\msw\setup.h to choose
  58    the features you would like to compile wxWidgets with[out].
  59
  60    and std iostreams are disabled with
  61    #define wxUSE_STD_IOSTREAM   0
  62
  63 -> type: cd c:\wxWidgets\build\msw
  64 -> type: make -f makefile.gcc  (if using GNU tools)
  65 or type: nmake -f makefile.vc   (if using MS VC++)
  66 etc.
  67
  68    See also docs/msw/install.txt for additional compilation options.
  69
  70 d) Borland (including free command line tools)
  71    Download tools from http://www.borland.com/downloads/
  72
  73    See docs/msw/install.txt for details; in brief:
  74
  75 -> type cd c:\wxWidgets\build\msw
  76 -> type make -f makefile.bcc
  77
  78 You can customize many things in the build process, detailed description is
  79 in docs/msw/install.txt.
  80
  81
  82 II) Unix ports
  83 --------------
  84
  85 Building wxGTK or wxMotif completely without configure
  86 won't ever work, but there is now a new makefile system
  87 that works without libtool and automake, using only
  88 configure to create what is needed.
  89
  90 In order to create configure, you need to have the
  91 GNU autoconf package (version > 2.54) installed
  92 on your system and type run "autoconf" in the base
  93 directory (or run the autogen.sh script in the same
  94 directory, which just calls autoconf). Note that you usually don't
  95 need to do this because configure is included in CVS.
  96
  97 Set WXWIN environment variable to the base directory such
  98 as ~/wxWidgets (this is actually not really needed).
  99
 100 -> type: export WXWIN=~/wxWidgets
 101 -> type: md mybuild
 102 -> type: cd mybuild
 103 -> type: ../configure --with-motif
 104 or type: ../configure --with-gtk
 105 -> type: make
 106 -> type: su <type root password>
 107 -> type: make install
 108 -> type: ldconfig
 109 -> type: exit
 110
 111 Call configure with --disable-shared to create a static
 112 library. Calling "make uninstall" will remove the installed
 113 library and "make dist" will create a distribution (not
 114 yet complete).
 115
 116 III) Windows using configure
 117 ----------------------------------------
 118
 119 wxWidgets can be built on Windows using MSYS (see
 120 http://www.mingw.org/), which is a POSIX build environment
 121 for Windows. With MSYS you can just ./configure && make (see also VII,
 122 Unix->Windows cross-compiling using configure).
 123
 124 Of course, you can also build the library using plain makefiles (see
 125 section I).
 126
 127 IV) Classic MacOS using CodeWarrior (eg MacOS 8.x/9.x)
 128 ----------------------------------------
 129
 130 Refer to the readme.txt and install.txt files in docs/mac to build
 131 wxWidgets under Classic Mac OS using CodeWarrior.
 132
 133 If you are checking out the CVS sources using cvs under Mac OS X and
 134 compiling under Classic Mac OS:
 135
 136 - make sure that all text files have a Mac OS type of 'TEXT' otherwise
 137   CodeWarrior may ignore them. Checking out the CVS sources using cvs
 138   under Mac OS X creates untyped files which can lead to compilation
 139   errors under CodeWarrior which are hard to track down.
 140
 141 - convert the xml files to CodeWarrior binary projects using the supplied
 142   AppleScript in docs/mac (M5xml2mcp.applescript for CodeWarrior 5.3)
 143
 144 V) MacOS X using configure and the Developer Tools
 145 ----------------------------------------
 146
 147 You need to have the Developer Tools installed. If this is not the case,
 148 you will need to register at the Apple Developer web site (this is a free
 149 registration) in order to download the Developer Tools installer.
 150
 151 In order to create configure, you need to have the
 152 GNU autoconf package (version >= 2.54) installed
 153 on your system and type run "autoconf" in the base
 154 directory (or run the autogen.sh script in the same
 155 directory, which just calls autoconf).
 156
 157 -> type: mkdir macbuild
 158 -> type: cd macbuild
 159 -> type: ../configure --with-mac
 160 or type: ../configure
 161 -> type: make
 162
 163 VI) OS/2
 164 ----------------------------------------
 165 No notes.
 166
 167 VII) Unix->Windows cross-compiling using configure
 168 --------------------------------------------------
 169
 170 First you'll need a cross-compiler; linux glibc binaries of MinGW and
 171 Cygwin (both based on egcs) can be found at
 172 ftp://ftp.objsw.com/pub/crossgcc/linux-x-win32. Alternative binaries,
 173 based on the latest MinGW release can be found at
 174 http://members.telering.at/jessich/mingw/mingwcross/mingw_cross.html
 175 Otherwise you can compile one yourself.
 176
 177 [ A Note about Cygwin and MinGW: the main difference is that Cygwin
 178 binaries are always linked against cygwin.dll. This dll encapsulates most
 179 standard Unix C extensions, which is very handy if you're porting unix
 180 software to windows. However, wxMSW doesn't need this, so MinGW is
 181 preferable if you write portable C(++). ]
 182
 183 You might want to build both Unix and Windows binaries in the same source
 184 tree; to do this make subdirs for each e.g. unix and win32. If you've
 185 already build wxWidgets in the main dir, do a 'make distclean' there,
 186 otherwise configure will get confused. (In any case, read the section 'Unix
 187 using configure' and make sure you're able to build a native wxWidgets
 188 library; cross-compiling errors can be pretty obscure and you'll want to be
 189 sure that your configure setup is basically sound.)
 190
 191 To cross compile the windows library, do
 192 -> cd win32
 193 (or whatever you called it)
 194 Now run configure. There are two ways to do this
 195 -> ../configure --host=i586-mingw32 --build=i586-linux --with-mingw
 196 where --build= should read whatever platform you're building on. Configure
 197 will notice that build and host platforms differ, and automatically prepend
 198 i586-mingw32- to gcc, ar, ld, etc (make sure they're in the PATH!).
 199 The other way to run configure is by specifying the names of the binaries
 200 yourself:
 201 -> CC=i586-mingw32-gcc CXX=i586-mingw32-g++ RANLIB=i586-mingw32-ranlib \
 202    DLLTOOL=i586-mingw32-dlltool LD=i586-mingw32-ld NM=i586-mingw32-nm \
 203    ../configure --host=i586-mingw32 --with-mingw
 204
 205 (all assuming you're using MinGW)
 206 By default this will compile a DLL, if you want a static library,
 207 specify --disable-shared.
 208
 209 Type
 210 -> make
 211 and wait, wait, wait. Don't leave the room, because the minute you do there
 212 will be a compile error :-)
 213
 214 NB: if you are using a very old compiler you risk to get quite a few warnings
 215     about "ANSI C++ forbids implicit conversion from 'void *'" in all places
 216     where va_arg macro is used. This is due to a bug in (some versions of)
 217     MinGW headers which may be corrected by upgrading your compier,
 218     otherwise you might edit the file
 219
 220     ${install_prefix}/lib/gcc-lib/i586-mingw32/egcs-2.91.57/include/stdarg.h
 221
 222     (instead of egcs-2.91.57 you may have something different), searching for
 223     the lines
 224
 225 /* Define __gnuc_va_list.  */
 226
 227 #ifndef __GNUC_VA_LIST
 228 #define __GNUC_VA_LIST
 229 #if defined(__svr4__) || defined(_AIX) || defined(_M_UNIX) || defined(__NetBSD__)
 230 typedef char *__gnuc_va_list;
 231 #else
 232 typedef void *__gnuc_va_list;
 233 #endif
 234 #endif
 235
 236     and adding "|| defined(_WIN32)" to the list of platforms on which
 237     __gnuc_va_list is char *.
 238
 239 If this is successful, you end up with a wx23_2.dll/libwx23_2.a in win32/lib
 240 (or just libwx_msw.a if you opted for a static build).
 241 Now try building the minimal sample:
 242
 243 -> cd samples/minimal
 244 -> make
 245
 246 and run it with wine, for example (or copy to a Windows box)
 247 -> wine minimal.exe
 248
 249 If all is well, do an install; from win32
 250 -> make install
 251
 252 Native and cross-compiled installations can co-exist peacefully
 253 (as long as their widget sets differ), except for wx-config. You might
 254 want to rename the cross-compiled one to i586-mingw32-wx-config, or something.
 255
 256 Cross-compiling TODO:
 257 ---------------------
 258 - resource compiling must be done manually for now (should/can we link the
 259 default wx resources into libwx_msw.a?) [ No we can't; the linker won't
 260 link it in... you have to supply an object file ]
 261 - static executables are HUGE -- there must be room for improvement.
