Hello, I have problems building an exampĺe from the command line with a Makefile using the g++ compiler. This is the Makefile:

#SelectExpand
  1CXX = g++ -std=c++14
  2
  3#Ruta donde está aleph
  4ALEPH = ~/Libraries/Aleph-w
  5
  6#Ruta dónde está instalada Allegro

The Alpeh-w is a Algorithms, data structure and miscelaneous library, so you don't need to worry about it. My problem is with allegro. It gives me thsi error after trying to build the program:

#SelectExpand
 1/home/egroj97/Code/Allegro/Allegr_Test/example.C:219: undefined reference to `al_init_image_addon'

Please, help

You're building an example manually? How did you install Allegro to begin with? The examples should have been built already.

Do this:

git clone https://github.com/liballeg/allegro5
cd allegro5
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

That'll clone and build Allegro and its examples for you. You should then be able to view each of the compiled examples by navigating to allegro5/build/examples.

Edit
Is that an example that came with Allegro 5, or one that you found somewhere else? I do not think you need "5.0"; I think instead it should just be "5" when using pkg-config.

Let's first make sure you can build without a Makefile. Try this in a terminal:

gcc example.C `pkg-config --cflags --libs allegro-5.0 allegro_ttf-5.0 allegro_init-5.0 allegro_draw-5.0 allegro_image-5.0 allegro_color-5.0`

And paste the error you get.
