Ensure that the required libraries and tools for C++ development are installed:<\/p>\n\n\n\n
Download and Compile wxWidgets<\/strong><\/p>\n\n\n\n Go to http:\/\/wxwidgets.org\/downloads\/ and download the link which says Source for Linux, MacOS etc.<\/em> This will download a bz2 file. Unzip this file into a directory of your choice. Now we have to compile the source to form a static library which will be linked to your application when it is built.<\/p>\n\n\n\n If you have unzipped the source into a folder called wxWidgets-3.1.5 then create a new folder within it for creating the library files. You can call it anything but for now we will call it wxWidgetsLib. <\/p>\n\n\n\n So now you have wxWidgets-3.1.5\/wxWidgetsLib<\/em><\/p>\n\n\n\n While you are in wxWidgets-3.1.5 run the following commands to build wxWidgets:<\/p>\n\n\n\n . If you want to use wxWebView control to embed a web browser then you have to add extra arguments to configure. For Ubuntu, you need to enable wxWebView and webKitGTK. But before that you need to install webkit for GTK 4.0 as below<\/p>\n\n\n\n If you want to use the latest wxAUI library to get a more modern UI with docks and resizable panels, then you need to enable the AUI library:<\/p>\n\n\n\n .\/configure –enable-shared –enable-utf8 –enable-aui<\/p>\n\n\n\n make<\/p>\n\n\n\n At this stage the wxWidgets library should be ready for use in your applications<\/p>\n\n\n\n Testing With A Sample Program<\/strong><\/p>\n\n\n Lets create a simple console based program as shown above. This can be saved as addition.cpp. We will use g++ to compile and link it into an executable:<\/p>\n\n\n\n Be sure to put the backticks for the arguments as shown above. They have to be backticks and not regular single quotes.<\/p>\n\n\n\n On completion you can run the program with:<\/p>\n\n\n\n The output will be as shown below:<\/p>\n\n\n\n What we did was create a console application using wxWidgets. Lets create a simple program which creates a default window:<\/p>\n\n\n\n window.h<\/p>\n\n\n window.cpp<\/p>\n\n\n main.h<\/p>\n\n\n main.cpp<\/p>\n\n\n To compile and link it run:<\/p>\n\n\n\n To run it type <\/p>\n\n\n\n .\/main <\/p>\n\n\n\n This will show a small resizable Window <\/p>\n\n\n\n For simple small programs g++ on the command line will suffice. But for larger projects, it is best to a make file.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" sudo apt-get install build-essential<\/code><\/p>\n\n\n\n sudo apt-get install libwxgtk3.2-dev<\/code><\/code><\/pre>\n\n\n\nmkdir wxWidgetsLib<\/code><\/p>\n\n\n\n\/configure --enable-shared --enable-u<\/code>tf8<\/p>\n\n\n\n sudo apt install libwebkit2gtk-4.1-dev \n.\/configure --enable-shared --enable-utf8 --enable-webview --enable-webviewwebkit\n<\/code><\/pre>\n\n\n\nmake<\/code><\/p>\n\n\n\n\n#include <wx\/string.h>\n#include <wx\/crt.h>\n\nint main (int argx, char **argv) {\n\n wxString str1 = wxT("Linux");\n wxString str2 = wxT("Windows");\n wxString str3 = wxT("MacOS");\n\n wxString str = str1+ wxT(" " ) + str2 + wxT(" ") + str3;\n wxPuts(str);\n}\n~ \n~ \n~ \n<\/pre><\/div>\n\n\ng++ addition.cpp `
