Building a wxWidgets project in VS Code - c++

Question

I try to start using Linux(Fedora 33) and now I've got a trouble. I want to use VS Code and it builds simple cpp projects correctly, but I want to make GUI using wxWidgets. So I created simple example, but it doesn't want to build it. I installed wxWidgets from rpm package. I also added pathes into includePath in configuration file. Now I want to show you the code and errors.
#include <wx/wxprec.h>
#ifndef WX_PRECOMP
#include <wx/wx.h>
#endif
int main() { return 0; }
tasks.json
{
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: g++ сборка активного файла",
"command": "/usr/bin/g++",
"args": [
"-g",
"${file}",
"-o",
"${fileDirname}/${fileBasenameNoExtension}"
],
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
},
"detail": "компилятор: /usr/bin/g++"
}
],
"version": "2.0.0"
}
launch.json
{
"version": "0.2.0",
"configurations": [
{
"name": "g++ - Сборка и отладка активного файла",
"type": "cppdbg",
"request": "launch",
"program": "${fileDirname}/${fileBasenameNoExtension}",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"setupCommands": [
{
"description": "Включить автоматическое форматирование для gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
],
"preLaunchTask": "C/C++: g++ сборка активного файла",
"miDebuggerPath": "/usr/bin/gdb"
}
]
}
c_cpp_properties.json
{
"configurations": [
{
"name": "Linux",
"includePath": [
"${workspaceFolder}/**",
"/usr/include/**",
"/usr/lib64/wx/include/**"
],
"defines": [],
"compilerPath": "/usr/bin/clang++",
"cStandard": "c17",
"cppStandard": "c++14",
"intelliSenseMode": "linux-clang-x64",
"compilerArgs": []
}
],
"version": 4
}
Now, there are no errors given me by intellisence, I think.
Compilers errors:
Запуск сборки…
/usr/bin/g++ -g /home/nikita/Workfiles/wxex/main.cpp -o /home/nikita/Workfiles/wxex/main
/home/nikita/Workfiles/wxex/main.cpp:1:10: фатальная ошибка: wx/wxprec.h: Нет такого файла или каталога
1 | #include <wx/wxprec.h>
| ^~~~~~~~~~~~~
компиляция прервана.
Сборка завершена с ошибками.
The terminal process failed to launch (exit code: -1).

Answer 1

Replace
#include <wx/wxprec.h>
#ifndef WX_PRECOMP
#include <wx/wx.h>
#endif
with
#include <wx/wx.h>

Answer 2

wxWidgets provides wx-config script under Unix which must be used to obtain the options necessary for compiling and linking programs using the library. Please run wx-config --cxxflags to obtain the full flags you need to put in your c_cpp_properties.json and also wx-config --libs to get the linker flags that you will need to use to make the program link, and not just compile, successfully.

Answer 3

As the person who starts using Linux AND wants to learn new library id recommend followinh:
Grab the source code from www.wxwidget.org/download
Unpack it somewhere
Open the terminal
cd wxWidgets-3.1.4
mkdir buildGTK
cd buildGTK
../configure --enable-debug
make
cd samples/minimal
Make
Now the last make command will display everything you need to include and link against. You will also have a samples code you can refer to when needed.
If you don't want to build the library from source - try the following
Open terminal
Type "which wx-config" (without quotes) and press ebter
Run "/path/to/wx-config --cxxflags" (without quots)
Run "/path/to/wx-config --libs" (without quotes)
Use the output from the commands above in you IDE.
HTH.
