Linking the Allegro library to a C++ application using the g++ compiler (Ubuntu)

Question

In trying to get Allegro (A C++ game programming library) to work with a very simple C++ application in Ubuntu 12.04, I am unable to get the program to compile with the allegro header definitions. It returns the error allegro.h - no such file or directory found. I tried running a pkg-config to find the proper linker command, but that didn't help in compilation.

I am almost certain it is installed correctly at this point. I tried using a pkg-config --cflags --libs allegro-5.0 for the include file paths, none of which worked when using in the g++ compile line.

Thanks in advance.

Answer 1

Running a pkg-config --cflags --libs allegro-5.0 told me wrong on the include path. It told me to use -I/usr/local/include and after some digging into that folder, I found that the include path is -I/usr/local/include/allegro5 instead. It is compiling fine now.
