FI MUNI - C and C++ examples

Examples related to talks at FI MUNI. Georgik's blog: http://georgik.sinusgear.com

Allegro

Allegro is library for interactive applications like games written in C.

Three examples for Allegro 5.0 library.

  • example-01 - display smiley
  • example-02 - display smiley when pressed space
  • example-03 - smiley follows mouse

Requirements: Allegro 5.0 (works also with 5.1) Package for Debian: liballegro5-dev

How to run:

cd allegro
make
./example-01
./example-02
./example-03

Check - unit test

Check is unit testing framework for C: http://libcheck.github.io/check/

This directory contains simple example. You can uncomment age++ to create bug and rerun tests.

How to run:

cd check
make
./test

curl

curl command line tool for sending requests via http and many other protocols. It is also able to create skeleton of C application for libcurl.

How to run:

cd curl
./generate-source-code.sh
./compile-source-code.sh
./download

Go language

Go examples based on: https://golang.org/

01-hello

How to run:

cd 01-hello
go run hello.go

02-conway

How to run

cd 02-conway
go run conway.go    

GTK+

GTK+ is library for GUI applications written in C. It has also bindings for many other languages.

Helloworld example from http://en.wikipedia.org/wiki/Gtk. Requires: GTK+-3 Package for Debian: libgtk-3-dev

How to run:

cd gtk
make
./helloworld

Gradle basics and C plugin

00-empty-project

Empty gradle project.

How to run:

gradle tasks

01-hello-task

Simple task to print string during build.

How to run:

gradle tasks
gradle hello

02-c-plugin

Simple usage C plugin. There is no working C code in this example.

How to run:

gradle tasks

03-executable

Gradle with C plugin with simple Hello application.

How to run (Shell):

gradle mE
cd build/binaries/mainExecutable
./main

How to run (PowerShell):

gradle mE
cd build\binaries\mainExecutable
.\main.exe

04-visual-studio

Gradle C plugin example with support for Visual Studio solution files.

How to run (PowerShell):

gradle mainVisualStudio
ii mainExe.sln

05-debian-package

Gradle plugin for packaging Debian/Ubuntu package. Gradle downloads plugin from repository.

How to run:

gradle helloExecutable prepare buildDeb

Debian package is available in directory build.

Gradle C++ plugin

01-hello-muni

Example of building C/C++ project by Gradle. Gradle is using build.gradle file in main project directory. Check out project layout. Source code is stored in src/main/cpp, because gradle is using "Build by convention". No further configuration is needed. Gradle is able to determine compiler chain and use available compiler, e.g. g++ or Visual Studio.

How to run:

cd gradle-cpp-plugin/01-hello-muni
gradle mainExecutable
cd build/binaries/mainExecutable
./01-hello-muni

02-hello-muni-with-gradle-wrapper

It's not necessary to download Gradle manually like in previous example. Gradle projects are sometimes provided with wrapper which downloads all necessary files with Gradle. It's sufficient to start wrapper and then you can work with local instance of Gradle. This is useful when you want to fix version of Gradle or simplify bootstrap process.

Configuration file in gradle/hello-with-wrapper/gradle contains reference to Gradle with VS 2013 support.

How to run:

cd gradle-cpp-plugin/02-hello-muni-with-gradle-wrapper
./gradlew mainExecutable  (or .\gradle.bat mainExecutable for PowerShell)
cd build/binaries/mainExecutable
./02-hello-muni-with-gradle-wrapper

03-hello-muni-with-debug

This example shows how to update build script to add debug flags for compilers like GCC or VS.

How to run:

cd gradle-cpp-plugin/03-hello-muni-with-debug
gradle mainExecutable
cd build/binaries/mainExecutable
./03-hello-muni-with-debug

04-hello-linux-package

Example shows how to create build of C++ application by Gradle and create Linux package. Linux package is based on Netflix Nebula OS plugin for Gradle: http://plugins.gradle.org/plugin/nebula.os-package

How to run:

cd gradle-cpp-plugin/04-hello-linux-package
gradle helloExecutable
gradle buildDeb buildRpm

DEB and RPM package is stored in build/distributions.

You can list content of DEB package:

dpkg -c build/distributions/hello_1.0-1_all.deb

Minunit testing

Minunit is very minimalistic C testing framework. It contains just two lines of code.

How to run:

cd minunit
make
./test

REST SDK

Example based on C++ REST SDK - Casablanca which has support for asynchronous calls. Documentation: http://msdn.microsoft.com/en-us/library/jj969455.aspx Project page: https://casablanca.codeplex.com/ This example requires Visual Studio 2013 with NuGet.

How to run (PowerShell + VS 2013):

cd rest\rest-client
ii rest-client.sln
right click the project and select: Manage NuGet Packages for solution
restore C++ REST SDK
CTRL+F5 to run the project

Simple DirectMedia Layer 2

SDL2 is multiplatform library suitable for developing applications like games. You can use Gradle to build SDL2 examples.

Preparing dependencies for Windows

Root project contains reference to SDL2 library. Type:

gradle prepare

It will download Windows version of SDL2 library for all projects. Libraries will be placed in directory build. Now you can build earch of subprojects.

01-sdl2-init

Simple example - init and quit SDL. How to build:

gradle clean mainExecutable

Shorter version:

gradle clean mE

It is possible to generate project for Visual Studio:

gradle mainVisualStudio

Compiled binary will be stored in:

build/binaries/mainExecutable

Copy required resources/dll to mainExecutable by command:

gradle prepare

02-sdl2-video - Visual Studio version

Open solution file in VisualStudio. Verify that SDL2 is installed in your solution. Go to Tools - NuGet Packaga Manager - Manage NuGet Packages for Solution. Search for SDL. Select Simple DirectMedia Layer version 2.x (it will be most likely the second package). Select install.

Now you'll be able to build the package.

02-sdl2-video - Gradle version

It's possible to build the same application by Gradle. Graphic initialization example for SDL2. Initialize graphic interface, load BMP file and display it.

Commands (PowerShell):

gradle prepare mE
cd build\binaries\mainExecutable
.\main.exe

Commands (Shell):

gradle prepare mE
cd build/binaries/mainExecutable
./main

node

Example from Node.js web site. Create simple server.

How to run:

cd node.js
node echo-server.js

Objective-C

Objective-C is primary programing language for Apple world. This is ismple Hello Muni example. Open this project in Xcode.

How to run:

cd objective-c
open hellomuni.xcodeproj

uv

libuv is library which has support for event loops, networking and many other features required by cloud computing. This library is core part of Node.js.

Requires: libuv (part of Node.js) Package for Debian: none, you need to build it from sources. You can use Node.js package.

How to run hello example:

cd libuv/hello
make
./hello

How to run echo_server example:

cd libuv/echo_server
make
./echo_server

Note: Do not forget to set LD_LIBRARY_PATH so the linker will be able to locate libuv E.g.: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
