Welcome to the forums.

1. Install the compiler and associated tools with


sudo apt-get install build-essential

2. Put the source code in a text file e.g. example.c. You can use any text editor to do this.
3. Compile and link with:


make example

4. Run the program


./example

Source code in a pdf file isn't very useful. Get your source code saved as a plain text file, like you make in text editors as gedit, mousepad or vim.

Install a compiler (gcc is the standard on Ubuntu, the gcc package will install the default version of gcc for your version of Ubuntu), some header files and you probably want make too. The package build-essential is a easy package that installs aforementioned packages automatically (although it wasn't really meant for that and includes some stuff that you don't need), but depending on what exactly you want to compile you may have to install additional header files. Those can be found in packages typically named libfoo-dev.

If you use make, you may have to write a makefile first, containing instructions how to run gcc. You can also run gcc directly from the terminal. You may need some command line options to set output file name, link libraries etc.

Some context might be useful. Are you trying to process sound files using the libsndfile API (http://www.mega-nerd.com/libsndfile/api.html) by any chance?

[spjackson]

Does the program you are trying to build come with any documentation? There may be other dependencies besides libsndfile. Nevertheless, I'll fly blind and suggest a possible solution to this immediate problem:

1. Install the dependency


sudo apt-get install libsndfile1-dev

2. Use it


gcc -o example example.c -llibsndfile
