   2 * The most simple case
   3 -----------------------
   4
   5 If you compile wxWidgets on Linux for the first time and don't like to read
   6 install instructions just do (in the base dir):
   7
   8 > ./configure --with-wine
   9 > make
  10 > su <type root password>
  11 > make install
  12 > ldconfig
  13 > exit
  14
  15 On all variants of Unix except Linux (and maybe except *BSD), shared libraries
  16 are not supported out of the box due to the utter stupidity of libtool, so you'll
  17 have to do this to get shared library support:
  18
  19 > ./configure --with-wine --disable-static --enable-shared
  20
  21 Then you'll have to edit the wrongly created libtool script. There are two
  22 important entries with respect to shared library creation, which are
  23
  24   archive_cmds="\$LD -shared ....
  25   archive_expsym_cmds="\$LD -shared ....
  26
  27 which should be something like
  28
  29   archive_cmds="\$CC -shared ....
  30   archive_expsym_cmds="\$CC -shared ....
  31
  32 Afterwards you can continue with
  33
  34 > make
  35 > su <type root password>
  36 > make install
  37 > ldconfig
  38 > exit
  39
  40 If you want to remove wxWidgets on Unix you can do this:
  41
  42 > su <type root password>
  43 > make uninstall
  44 > ldconfig
  45 > exit
  46
  47 * The expert case
  48 -----------------
  49
  50 If you want to do some more serious cross-platform programming with wxWidgets,
  51 such as for GTK and Motif, you can now build two complete libraries and use
  52 them concurrently. For this end, you have to create a directory for each build
  53 of wxWidgets - you may also want to create different versions of wxWidgets
  54 and test them concurrently. Most typically, this would be a version configured
  55 with --enable-debug_flag and one without. Note, that only one build can currently
  56 be installed, so you'd have to use local version of the library for that purpose.
  57 For building three versions (one GTK, one WINE and a debug version of the WINE
  58 source) you'd do this:
  59
  60 md buildmotif
  61 cd buildmotif
  62 ../configure --with-motif
  63 make
  64 cd ..
  65
  66 md buildwine
  67 cd buildwine
  68 ../configure --with-wine
  69 make
  70 cd ..
  71
  72 md buildwined
  73 cd buildwined
  74 ../configure --with-wine --enable-debug_flag
  75 make
  76 cd ..
  77
  78 * The most simple errors
  79 ------------------------
  80
  81 wxWINE doesn't work yet as WINE isn't really up to the task yet.
  82
  83 You get errors during compilation: The reason is that you probably have a broken
  84 compiler, which includes almost everything that is called gcc. If you use gcc 2.8
  85 you have to disable optimisation as the compiler will give up with an internal
  86 compiler error.
  87
  88 If there is just any way for you to use egcs, use egcs. We cannot fix gcc.
  89
  90 You get immediate segfault when starting any sample or application: This is either
  91 due to having compiled the library with different flags or options than your program -
  92 typically you might have the __WXDEBUG__ option set for the library but not for your
  93 program - or due to using a broken compiler (and its optimisation) such as GCC 2.8.
  94
  95 * The most simple program
  96 -------------------------
  97
  98 Now create your super-application myfoo.app and compile anywhere with
  99
 100 g++ myfoo.cpp `wx-config --libs --cflags` -o myfoo
 101
 102 * General
 103 -----------------------
 104
 105 The Unix variants of wxWidgets use GNU configure. If you have problems with your
 106 make use GNU make instead.
 107
 108 If you have general problems with installation, read my homepage at
 109
 110   http://wesley.informatik.uni-freiburg.de/~wxxt
 111
 112 for newest information. If you still don't have any success, please send a bug
 113 report to one of our mailing lists (see my homepage) INCLUDING A DESCRIPTION OF
 114 YOUR SYSTEM AND YOUR PROBLEM, SUCH AS YOUR VERSION OF WINE, WXWINE, WHAT DISTRIBUTION
 115 YOU USE AND WHAT ERROR WAS REPORTED. I know this has no effect, but I tried...
 116
 117 * GUI libraries
 118 -----------------------
 119
 120 wxWidgets/WINE requires the WINE library to be installed on your system.
 121
 122 You can get the newest version of the WINE from the WINE homepage at:
 123
 124   http://www.winehq.com
 125
 126 * Create your configuration
 127 -----------------------------
 128
 129 Usage:
 130     ./configure options
 131
 132 If you want to use system's C and C++ compiler,
 133 set environment variables CC and CCC as
 134
 135     % setenv CC cc
 136     % setenv CCC CC
 137     % ./configure options
 138
 139 to see all the options please use:
 140
 141     ./configure --help
 142
 143 The basic philosophy is that if you want to use different
 144 configurations, like a debug and a release version,
 145 or use the same source tree on different systems,
 146 you have only to change the environment variable OSTYPE.
 147 (Sadly this variable is not set by default on some systems
 148 in some shells - on SGI's for example). So you will have to
 149 set it there. This variable HAS to be set before starting
 150 configure, so that it knows which system it tries to
 151 configure for.
 152
 153 Configure will complain if the system variable OSTYPE has
 154 not been defined. And Make in some circumstances as well...
 155
 156
 157 * General options
 158 -------------------
 159
 160 Given below are the commands to change the default behaviour,
 161 i.e. if it says "--disable-threads" it means that threads
 162 are enabled by default.
 163
 164 Many of the configure options have been thoroughly tested
 165 in wxWidgets snapshot 6, but not yet all (ODBC not).
 166
 167 You must do this by running configure with either of:
 168
 169     --with-wine              Use the WINE library
 170
 171 The following options handle the kind of library you want to build.
 172
 173     --enable-threads        Compile with thread support. Threads
 174                             support is also required for the
 175                             socket code to work.
 176
 177     --disable-shared        Do not create shared libraries.
 178
 179     --disable-optimise        Do not optimise the code. Can
 180                             sometimes be useful for debugging
 181                             and is required on some architectures
 182                             such as Sun with gcc 2.8.X which
 183                             would otherwise produce segvs.
 184
 185     --enable-profile        Add profiling info to the object
 186                             files. Currently broken, I think.
 187
 188     --enable-no_rtti        Enable compilation without creation of
 189                             C++ RTTI information in object files.
 190                             This will speed-up compilation and reduce
 191                             binary size.
 192
 193     --enable-no_exceptions  Enable compilation without creation of
 194                             C++ exception information in object files.
 195                             This will speed-up compilation and reduce
 196                             binary size. Also fewer crashes during the
 197                             actual compilation...
 198
 199     --enable-mem_tracing    Add built-in memory tracing.
 200
 201     --enable-dmalloc        Use the dmalloc memory debugger.
 202                             Read more at www.letters.com/dmalloc/
 203
 204     --enable-debug_info     Add debug info to object files and
 205                             executables for use with debuggers
 206                             such as gdb (or its many frontends).
 207
 208     --enable-debug_flag     Define __DEBUG__ and __WXDEBUG__ when
 209                             compiling. This enable wxWidgets' very
 210                             useful internal debugging tricks (such
 211                             as automatically reporting illegal calls)
 212                             to work. Note that program and library
 213                             must be compiled with the same debug
 214                             options.
 215
 216 * Feature Options
 217 -------------------
 218
 219 Many of the configure options have been thoroughly tested
 220 in wxWidgets snapshot 6, but not yet all (ODBC not).
 221
 222 When producing an executable that is linked statically with wxGTK
 223 you'll be surprised at its immense size. This can sometimes be
 224 drastically reduced by removing features from wxWidgets that
 225 are not used in your program. The most relevant such features
 226 are
 227
 228     --without-libpng    Disables PNG image format code.
 229
 230     --without-libjpeg    Disables JPEG image format code.
 231
 232 {   --without-odbc          Disables ODBC code. Not yet. }
 233
 234     --disable-resources     Disables the use of *.wxr type
 235                             resources.
 236
 237     --disable-threads       Disables threads. Will also
 238                             disable sockets.
 239
 240     --disable-sockets       Disables sockets.
 241
 242     --disable-dnd           Disables Drag'n'Drop.
 243
 244     --disable-clipboard     Disables Clipboard.
 245
 246     --disable-serial        Disables object instance serialisation.
 247
 248     --disable-streams       Disables the wxStream classes.
 249
 250     --disable-file          Disables the wxFile class.
 251
 252     --disable-textfile      Disables the wxTextFile class.
 253
 254     --disable-intl          Disables the internationalisation.
 255
 256     --disable-validators    Disables validators.
 257
 258     --disable-accel         Disables accel.
 259
 260 Apart from disabling certain features you can very often "strip"
 261 the program of its debugging information resulting in a significant
 262 reduction in size.
 263
 264 * Compiling
 265 -------------
 266
 267 The following must be done in the base directory (e.g. ~/wxGTK
 268 or ~/wxWin or whatever)
 269
 270 Now the makefiles are created (by configure) and you can compile
 271 the library by typing:
 272
 273     make
 274
 275 make yourself some coffee, as it will take some time. On an old
 276 386SX possibly two weeks. During compilation, you'll get a few
 277 warning messages depending in your compiler.
 278
 279 If you want to be more selective, you can change into a specific
 280 directory and type "make" there.
 281
 282 Then you may install the library and its header files under
 283 /usr/local/include/wx and /usr/local/lib respectively. You
 284 have to log in as root (i.e. run "su" and enter the root
 285 password) and type
 286
 287         make install
 288
 289 You can remove any traces of wxWidgets by typing
 290
 291         make uninstall
 292
 293 If you want to save disk space by removing unnecessary
 294 object-files:
 295
 296      make clean
 297
 298 in the various directories will do the work for you.
 299
 300 * Creating a new Project
 301 --------------------------
 302
 303 1) The first way uses the installed libraries and header files
 304 automatically using wx-config
 305
 306 g++ myfoo.cpp `wx-config --libs` `wx-config --cflags` -o myfoo
 307
 308 Using this way, a make file for the minimal sample would look
 309 like this
 310
 311 CC = g++
 312
 313 minimal: minimal.o
 314     $(CC) -o minimal minimal.o `wx-config --libs`
 315
 316 minimal.o: minimal.cpp mondrian.xpm
 317     $(CC) `wx-config --cflags` -c minimal.cpp -o minimal.o
 318
 319 clean:
 320     rm -f *.o minimal
 321
 322 This is certain to become the standard way unless we decide
 323 to stick to tmake.
 324
 325 2) The other way creates a project within the source code
 326 directories of wxWidgets. For this endeavour, you'll need
 327 the usual number of GNU tools, at least
 328
 329 GNU automake version 1.4
 330 GNU autoheader version 2.14
 331 GNU autoconf version 2.14
 332 GNU libtool version 1.3
 333
 334 and quite possibly
 335
 336 GNU make
 337 GNU C++
 338
 339 and if you have all this then you probably know enough to
 340 go ahead yourself :-)
 341

 349 Addition notes by Julian Smart, August 2002
 350 ===========================================
 351
 352 I've fixed some compile errors, and got as far as
 353 compiling wxWINE, but actually linking a sample will take
 354 further work.
 355
 356 To compile wxWINE, export these variables:
 357
 358 export CPPFLAGS=-I/usr/local/include/wine
 359 export LDFLAGS=-L/usr/local/lib/wine
 360
 361 and configure with:
 362
 363 configure --disable-static --enable-shared --enable-gui \
 364  --with-wine --without-libpng --enable-debug_flag --enable-log \
 365  --enable-debug_info --enable-ole --enable-clipboard --enable-dataobj \
 366  --enable-debug --enable-threads --disable-sockets \
 367  --with-libjpeg --enable-debug_cntxt
 368
 369 Compiling a sample won't work yet because 'winebuild' needs
 370 to be called, and the resuling C file compiled and linked.
 371 Plus, Windows DLLs need to be imported.
 372
 373 Note that the documentation on the WINE web site on using
 374 winebuild is out of date (August 2002) -- the spec file no
 375 longer supports import and type keywords. Instead look at
 376 samples in the WINE 'programs' directory for inspiration
 377 and compile options to use. It's probable that the
 378 wxWINE library will need recompiling with different options.
 379
 380 Any progress on this front will be very welcome.
