How to release a sfml-program for several distribution?
« on: August 20, 2016, 11:16:20 am »
Hi, my project of coding some stuff with sfml is in the final state.
Now I like to build a release for students but I'm very new to cmake/ make .

Do anybody know a good tutorial or bool to release an C-program, based on SFML/CSFML 2.3 to another machine like Ubuntu 14.04 ?

Thank you very much

1. Build your own sfml. 2. Build your executable with a RPATH that finds the library relative to the executable ($ORIGIN). 3. Package the library files alongside your executable in the expected location.

I always wonder with that, how are SFML's dependencies handled? Can I compile this on Debian and then really run it on Ubuntu, Arch and Gentoo? What if runtime libs differ?

I have tried compiling an application in the past that ran on both ubuntu and arch linux. I never really knew which dependencies to ship so I just copied the ones that were asked for when starting the app. The result was that a year later on a different system it sometimes missed some library.
So I decided to take a more detailed look into this today and these are my findings (some information may be incorrect, these are simply my observations). Since I do not have ubuntu I used docker from arch linux.

There are 2 problems with distributing the executable:
1) You can only run the executable on newer systems (or the same) as the one you compile with.
(click to show/hide)

2) Not all dependencies should be shipped.
(click to show/hide)

A third problem might be 32bit vs 64bit, I didn't test with that but I doubt that my 64bit app will just run on a 32bit linux.

The following test program should run out of the box on anything newer than ubuntu 14.04 (only tested running on arch linux):

This is the code that I have in my cmake script to set the RPATH
Code: [Select]
set(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE)
set(CMAKE_INSTALL_RPATH "$ORIGIN/lib/:$$ORIGIN/lib/")
