How to build & install GLFW 3 and use it in a Linux project



Answers

Note that you do not need that many -ls if you install glfw with the BUILD_SHARED_LIBS option. (You can enable this option by running ccmake first).
This way sudo make install will install the shared library in /usr/local/lib/ligglfw.so. You can then compile the example file with a simple:

g++ main.cpp -L /usr/local/lib/ -lglfw

Then do not forget to add /usr/local/lib/ to the search path for shared libraries before running your program. This can be done using:

export LD_LIBRARY_PATH=/usr/local/lib:${LD_LIBRARY_PATH}

And you can put that in your ~/.bashrc so you don't have to type it all the time.

Question

GLFW3

Last night I was working late trying to build the GLFW 3 packages for Linux from source. This process took me a very long time, about 3 hours in total, partly because I am unfamiliar with CMake, and partly because I am was unfamiliar with GLFW.

I hope that this post will save you from the difficulty I had yesterday! I thought I should make a short write-up, and hopefully save you several hours of your life...

Thanks to "urraka", "b6" and "niklas" on the #glfw IRC channel, I have been able to get glfw version 3.0.1 working.

It turns out this is not a trivial process (certainly not for me, I am no expert) as there is not much documentation on the web about glfw3, particularly about setting it up with CMake.

I was asked to split this into a question and answer section, and so I have done that, and the answer parts are now below.

Are you a maintainer of GLFW, or a member of the GLFW team?

If any of the maintainers of GLFW3 see this, then my message to them is please add a "setting up GLFW3 on Windows, Mac OS X and Linux" section to your website! It is quite easy to write programs with GLFW, since the online documentation is quite good, a quick scan of all the available classes and modules and you'll be ready to go. The example of a test project featured here is also very good. The two main problems I found were, firstly how do I set up GLFW3 on my system, and secondly how to I build a GLFW3 project? These two things perhaps aren't quite clear enough for a non-expert.

Edit

Had a brief look today (Date: 2014-01-14) it looks as if the GLFW website has undergone heavy changes since I last looked and there is now a section on compiling GLFW and buliding programs with GLFW, which I think are new.




Since the accepted answer does not allow more edits, I'm going to summarize it with a single copy-paste command (Replace 3.2.1 with the latest version available in the first command):

version="3.2.1" && \
wget "https://github.com/glfw/glfw/releases/download/${version}/glfw-${version}.zip" && \
unzip glfw-${version}.zip && \
cd glfw-${version} && \
sudo apt-get install cmake xorg-dev libglu1-mesa-dev && \
sudo cmake -G "Unix Makefiles" && \
sudo make && \
sudo make install

If you want to compile a program use the following commands:

g++ -std=c++11 -c main.cpp && \
g++ main.o -o main.exec -lGL -lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi -ldl -lXinerama -lXcursor

If you are following the learnopengl.com tutorial you may have to set up GLAD as well. In such case click on this link

http://glad.dav1d.de/#profile=core&specification=gl&api=gl%3D3.3&api=gles1%3Dnone&api=gles2%3Dnone&api=glsc2%3Dnone&language=c&loader=on

and then click on the "Generate" button at the bottom right corner of the website and download the zip file. Extract it and compile the sources with the following command:

g++ glad/src/glad.c -c -Iglad/include

Now, the commands to compile your program become like this:

g++ -std=c++11 -c main.cpp -Iglad/include && \
g++ main.o glad.o -o main.exec -lGL -lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi -ldl -lXinerama -lXcursor
