=head1 NAME README.txt - build and installation instructions =head1 DESCRIPTION Alien::wxWidgets allows wxPerl to easily find information about your wxWidgets installation. It can store this information for multiple wxWidgets versions or configurations (debug, Unicode, etc.). It can also build and install a private copy of wxWidgets as part of the build process. =head1 Installing wxWidgets If you do not know how to do it, please answer 'yes' to the question 'Do you want to build wxWidgets?'; Alien::wxWidgets will build and install a copy of wxWidgets for you. =head1 Installing Alien::wxWidgets Please note that the steps below can be repeated multiple times in order install multiple configurations (differing for the wxWidgets version, compiler, compiler version, debug/unicode settings). =head2 Unices and Mac OS X Important: If you are going to use the system wxWidgets or your own build of wxWidgets then either your required wx-config must be the first wx-config in the PATH or the WX_CONFIG environment variable must be set to the full path to wx-config. The environment WX_CONFIG variable can also be used to specify a different wx-config. perl Build.PL perl Build perl Build test perl Build install =head3 Requirements for building on Unices If you are going to ask Alien::wxWidgets to build wxWidgets you will need to install development prerequisites. The following is the list for Ubuntu but you can adapt for your own distribution where the package names may vary. gcc g++ libgtk2.0-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libglu1-mesa-dev libexpat1-dev libtiff4-dev libpng12-dev libjpeg-dev libcairo2-dev freeglut3-dev libxmu-dev libwebkitgtk-dev* To build the wxWebView componenent you need libwebkitgtk version 1.3.1 or greater. For Linux distributions currently this means a fairly recent release. For example, Ubuntu ge 11.10 If you do not have a recent enough libwebkitgtk installed then configure will simply not build the library. This is harmless. =head2 Windows If you are going to build your own wxWidgets then set WXDIR=C:\Path\to\wxWidgets Then whether you have built your own wxWidgets or not: perl Build.PL perl Build perl Build test perl Build install Important: If you do not allow Alien to build wxWidgets, the command line options to Build.PL must match the build settings used to build wxWidgets. =head2 Command Line Options for build perl Build.PL --wxWidgets-graphicscontext For wxWidgets 2.8.x this flag will cause wxGraphicsContext to be built and used. On Windows, your compiler must support GDI+. For wxWidgets 2.9.x, the build system detects whether wxGraphicsContext is supported. However, the default for any flavour of MinGW or MSVC 6 is to assume that wxGraphicsContext is NOT supported. So if you know that wxGraphicsContext IS supported, you can use this flag to force inclusion. perl Build.PL --wxWidgets-unicode=1 Only relevant for wxWidgets 2.8.x, indicate if you want a unicode build. --wxWidgets-unicode=1|0, default is 1 perl Build.PL --wxWidgets-build=0 Indicate if you want wxWidgets to be downloaded and built --wxWidgets-build=1|0, default depends on whether Aline-wxWidgets finds a usable wxWidgets installation on your system. An explict value always overrides the default. Always use an explicit flag if you want to avoid prompts. perl Build.PL --wxWidgets-version=2.8.12 If --wxWidgets-build=1, indicate the version of wxWidgets to build. e.g. --wxWidgets-version=2.9.4. The current default is 2.8.12. Always use an explicit flag if you want to avoid prompts. perl Build.PL --wxWidgets-source=tar.gz If --wxWidgets-build=1, indicate the type of archive to download e.g. --wxWidgets-source=tar.bz2, then default for wxWidgets 2.8.x is tar.gz and the default for wxWidgets 2.9.x is tar.bz2. Always use an explicit flag if you want to avoid prompts. perl Build.PL --wxWidgets-build-opengl=1 Build the wxGLCanvas libraries. --wxWidgets-build-opengl=1|0 default is 1. Always use an explicit flag if you want to avoid prompts. perl Build.PL --wxWidgets-extraflags="--disable-compat26" On Unices and Mac OS X you may use this to pass through any flags you may wish to configure. Doing so however will drop any additional default flags that Alien wxWidgets would normally pass to configure to ensure that wxWidgets builds as required on your system. This approach is used so that you can use this to configure precisely to your requirement and not have Alien-wxWidgets override it. e.g. --wxWidgets-extraflags="CC=gcc-4.0 --with-expat=builtin --disable-compat28" On Windows this option can be used to pass options directly to mingw32-make or nmake. You can usefully pass any of the options in build/msw/config.(vc|gcc) e.g. --wxWidgets-extraflags="USE_STC=0 VENDOR=anameIchose" perl Build.PL --wxWidgets-userpatch=/some/path/to/user.patch If you have automated building scripts and use some wxWidgets customisations you may give the path to a patch file (unified diff style) to be applied to the wxWidgets source. Any standard Alien::wxWidgets patches will be applied first. perl Build.PL --prefix Set a custom installation prefix. Works exactly the same as perl Makefile.PL PREFIX=/some/path e.g. --prefix=/some/custom/path =cut
