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://check.sourceforge.net/

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

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

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.

Note for Visual Studio 2013: Use Gradle at least night build 1.10-20131122230018

How to run:

cd gradle/hellomuni
gradle mainExecutable
cd build/binaries/mainExecutable
./hellomuni

Gradle with wrapper

In gradle/hellomuni example you have to download and install Gradle manually. 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/hello-with-wrapper
./gradlew mainExecutable  (or .\gradle.bat mainExecutable for PowerShell)
cd build/binaries/mainExecutable
./hello-with-wrapper

Minunit testing

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

How to run:

cd minunit
make
./test

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
