Installation
The simplest case
If you compile wxWidgets on Linux for the first time and don't like to read install instructions just do the following in wxWidgets directory:
$ mkdir buildgtk $ cd buildgtk $ ../configure --with-gtk $ make $ sudo make install $ sudo ldconfig
(if you get "ldconfig: command not found", try using /sbin/ldconfig)
If you don't do the make install part, you can still use the libraries from the buildgtk directory, but they may not be available to other users.
Note that by default, GTK 3 is used. GTK 2 can be specified with --with-gtk=2 configure option.
If you want to use CMake, please see CMake Overview for building wxWidgets using it.
Prerequisites
To build wxWidgets, you need to have a number of libraries on your system. While all of them may be compiled from source, under Linux systems it is much more common to install the development packages containing the headers and library files.
At the very least, you will need GTK libraries themselves. Unfortunately the exact package names differ between different Linux distributions, but for Debian and Debian-based distribution these libraries are part of libgtk-3-dev package, while in Fedora and other RPM-based distributions the same package is known as gtk3-devel.
For OpenGL support, you need libgl1-mesa-dev and libglu1-mesa-dev packages under Debian and mesa-libGL-devel and mesa-libGLU-devel under Fedora. For EGL support, libegl1-mesa-dev or mesa-libEGL-devel is needed.
wxMediaCtrl implementation requires GStreamer and its plugins development packages, i.e. either libgstreamer-plugins-baseVERSION-dev or gstreamerVERSION-plugins-base-devel, where VERSION should be 1.0, but 0.10 is still supported as well for compatibility with old systems.
wxWebRequest requites libcurl development package, e.g. libcurl4-openssl-dev or libcurl-devel.
wxWebView requires libwebkit2gtk-4.0-dev under Debian and webkit2gtk3-devel under Fedora.
For the different image format libraries (PNG, JPEG, TIFF) as well as zlib, you may install the corresponding libNAME-dev or -devel libraries or use the built-in versions of them, i.e. the same libraries compiled as part of wxWidgets, instead if you prefer.
Troubleshooting
IMPORTANT NOTE: When sending bug reports tell us the exact version of wxWidgets you are using as well as what compiler on what system. One example: wxGTK 3.0.5, GCC 9.3.1, Fedora 31.
For any configure errors: please look at config.log file which was generated during configure run, it usually contains some useful information.
If configure reports that you don't have GTK installed, please check that the appropriate development package is available on your system and not just the GTK libraries themselves. You can use pkg-config --modversion gtk+-3.0 (or 2.0) to check that this is the case.
You get errors from make: please use GNU make instead of the native make program. Currently wxWidgets can be built only with GNU make, BSD make and Solaris make. Other versions might work or not.
You get immediate crashes when starting any sample or application: This may be due to having compiled the library with different flags or compiler options than your program or using the headers from a different version of the library that is being used during run-time. If you have multiple versions of wxWidgets installed, please try uninstalling the ones you don't need and rebuilding.
The simplest program
Now create your super-application myfoo.cpp and compile anywhere with
g++ myfoo.cpp `wx-config --libs --cxxflags` -o myfoo
Configure options
This section documents some of the most important configure options. It is not exhaustive, please refer to configure --help for the full list of options.
Note that the options documented below are given in the form indicating how to change the default behaviour, i.e. if it says "--disable-optimise" it means that optimizations are enabled by default.
All standard configure options are supported, e.g. you can choose --prefix to select the directory to install the libraries to. Also note that cross-compiling is fully supported, just specify the --host option as usual (please refer to autoconf manual for more information).
The following options can be used to specify the kind and number of libraries to build:
--disable-shared
Do not create shared libraries, but build static libraries instead.--enable-monolithic
Build wxWidgets as single library instead of as several smaller libraries (which is the default since wxWidgets 2.5.0).
Options for third party dependencies: wxWidgets may use other libraries present on the current system, see the prerequisites section above. For some of these libraries, wxWidgets also provides built-in versions, that can be linked into wx libraries themselves, which can be useful to minimize external dependencies. By default, system versions will be used if available, but --with-xxx=builtin configure option may be used to override this.
--disable-sys-libs
Don't use system libraries when there is a built-in version included in wxWidgets. This is equivalent to using –with-xxx=builtin for all libraries that have built-in versions. Note that other system libraries can, and typically will, still be used if found.--without-libpng
Disables PNG image format code. Use neither the system nor the builtin libpng (although GTK itself still uses it).--without-libjpeg
Disables JPEG image format code. Don't use libjpeg.--without-libtiff
Disables TIFF image format code. Don't use libtiff.--without-expat
Disable XML classes based on Expat parser. Don't use expat library.--without-liblzma
Disable LZMA compression support. Don't use liblzma.--without-libcurl
Don't use libcurl even if it's available. Disables wxWebRequest.--without-opengl
Disable OpenGL integration with wxGLCanvas. Don't use OpenGL or EGL libraries.--disable-glcanvasegl
Disable EGL support even if it is available (it would be used if it is, by default).--disable-mediactrl
Disable wxMediaCtrl. Don't use GStreamer libraries.--disable-webview
Disable wxWebView. Don't use webkit2gtk and its multiple dependencies.
Normally, you won't have to choose a toolkit, because configure defaults to wxGTK anyhow. However you need to use this option to explicitly specify the version of GTK to use, e.g.:
--with-gtk=3
Use GTK 3. Default.--with-gtk=2
Use GTK 2.--with-gtk=1
Use GTK 1.2. Obsolete.
Some other general compilation options:
--disable-optimise
Do not optimise the code. Can be useful for debugging but shouldn't be used for production builds.--disable-unicode
Disable Unicode support. Not recommended.--enable-no_rtti
Enable compilation without creation of C++ RTTI information in object files. This will speed-up compilation and reduce binary size.--enable-no_exceptions
Enable compilation without creation of C++ exception information in object files. This will speed-up compilation and reduce binary size.--enable-debug_info
Add debug info to object files and executables for use with debuggers such as gdb (or its many frontends).--enable-debug_flag
Enable internal debugging checks, that are very useful during development and allow to diagnose illegal parameters to wxWidgets functions as long as the application doesn't predefineNDEBUG(see Debugging).--enable-debug
Same as--enable-debug_infoand--enable-debug_flagtogether. Typically this is the option you want to use.
To reduce the final libraries (or executables, when linking statically) size, many wxWidgets features may be disabled. Here is a list of some of them:
--disable-pnm
Disables PNM image format code.--disable-gif
Disables GIF image format code.--disable-pcx
Disables PCX image format code.--disable-iff
Disables IFF image format code.--disable-resources
Disables the use of *.wxr type resources.--disable-threads
Disables threads. Will also disable sockets.--disable-sockets
Disables sockets.--disable-dnd
Disables Drag'n'Drop.--disable-clipboard
Disables Clipboard.--disable-streams
Disables the wxStream classes.--disable-file
Disables the wxFile class.--disable-textfile
Disables the wxTextFile class.--disable-intl
Disables the internationalisation.--disable-validators
Disables validators.
Please remember that the full list of options can be seen in configure --help output.
Building the libraries
After running configure, just run make from the same directory. Building can take some time and it's strongly recommended to use --jobs option with GNU make, e.g. make -j8 if you have 8 logical CPU cores.
Then you may install the library and its header files under /usr/local/include/wx and /usr/local/lib respectively. You have to perform the following command as root, using either su or sudo:
$ make install
After installing, you can run make clean in the original directory or just remove it entirely if you don't plan to build wxWidgets again in the near future.
Note that installing the library is not required and it can also be used from the build directory by simply specifying the full path to wx-config script located in it when building your application.
Building your project
You need to use the compilation flags returned by wx-config --cxxflags and linking flags returned by wx-config --libs, which may be combined into a single invocation:
g++ myfoo.cpp `wx-config --cxxflags --libs` -o myfoo
A simple makefile for a program using wxWidgets could be written in the following way (note that if you are copying and pasting this into your makefile, the leading spaces must be replaced by a TAB character):
program: program.o
$(CXX) -o program program.o `wx-config --libs`
program.o: program.cpp
$(CXX) `wx-config --cxxflags` -c program.cpp -o program.o
clean:
$(RM) program.o program
.PHONY: clean
If your application uses only some of wxWidgets libraries, you can specify required libraries when running wx-config. For example, wx-config --libs=html,core will only output link command to link with libraries required by core GUI classes and wxHTML classes. See the manual for more information on the libraries.
