Can't link graphics module of SFML on Linux

[japanskcykel]

EDIT3: Solved! I compiled SFML from source and everything is working now!

Hello! I have been trying to get the awesome SFML 2.1 framework to work on my Linux (CrunchBang, built on Debian stable) machine, but no luck. When compiling the following way:

g++ -std=c++11 -Wall -Wextra -L../libraries/SFML-2.1/lib -Wl,-rpath=../libraries/SFML-2.1/lib -lsfml-system -lsfml-window -lGLEW -lsfml-graphics -o LD29 LD29.o

I get:

/usr/bin/ld: warning: libGLEW.so.1.5, needed by ../libraries/SFML-2.1/lib/libsfml-graphics.so, not found (try using -rpath or -rpath-link)
../libraries/SFML-2.1/lib/libsfml-graphics.so: undefined reference to `memcpy@GLIBC_2.14'

I have attached the source code and makefile. I am running under Debian stable, G++ verison is 4.7.
Any help is welcome! Thanks a bunch

EDIT: Forgot to mention, I do have GLEW installed. When running "dpkg -l | grep glew" I get:

ii  libglew-dev:amd64                     1.7.0-3                            amd64        OpenGL Extension Wrangler - development environment
ii  libglew1.7:amd64                      1.7.0-3                            amd64        OpenGL Extension Wrangler - runtime environment

EDIT2: I am now trying to compile SFML from source. Wish me luck! (I'll post the results)

I've just been running into the same issue on Debian 7.4 stable (Wheezy) (64bits):

../SFML-2.1/lib/libsfml-graphics.so: undefined reference to `memcpy@GLIBC_2.14'

I found no way to install the right GLib and "dpkg -l | grep glib" gives me the following:

ii  gir1.2-glib-2.0                       1.32.1-1                           amd64        Introspection data for GLib, GObject, Gio and GModule
ii  glib-networking:amd64                 2.32.3-1                           amd64        network-related giomodules for GLib
ii  glib-networking-common                2.32.3-1                           all          network-related giomodules for GLib - data files

ii  libglib2.0-0:amd64                    2.33.12+really2.32.4-5             amd64        GLib library of C routines
ii  libjson-glib-1.0-0:amd64              0.14.2-1                           amd64        GLib JSON manipulation library
ii  libtelepathy-glib0:amd64              0.18.2-2                           amd64        Telepathy framework - GLib library

Is recompiling SFML the only way.. ? Can't it be fixed on SFML binaries side?

Any help is appreciated
Thanks!

This is the package you want: https://packages.debian.org/search?keywords=libc6
The "libc6-dev" one.

Check this link for help if needed: http://unix.stackexchange.com/questions/85505/need-to-install-glibc-2-14-on-wheezy

[Ceylo]

Hmmmm when doing "apt-get -t testing install libc6-dev" I get this…

Reading package lists... Done
E: The value 'testing' is invalid for APT::Default-Release as such a release is not available in the sources

And no better result with the other command:

~# apt-get install libc6-dev=2.17-7
Reading package lists... Done
Building dependency tree      
Reading state information... Done
E: Version '2.17-7' for 'libc6-dev' was not found
~# apt-get install libc6-dev=2.17
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Version '2.17' for 'libc6-dev' was not found

And of course "apt-get install libc6-dev" says it's already installed.
So I really don't know what to do :/

I also tried to follow http://forums.spry.com/debian/620-how-install-testing-packages-debian-stable-apt-get.html and https://we.riseup.net/debian/installing-testing-packages-on-stable to no avail 

Not quite used to Linux so sorry for the newbie questions

[dabbertorres]

Did you read this link? http://www.debian.org/doc/manuals/apt-howto/ch-apt-get.en.html#s-default-version

You need to edit "/etc/apt/apt.conf" (create it if it doesn't exist), and make it contain the following:

APT::Default-Release "stable"

[Ceylo]

Not this link but on the one I read it was stated too

Code: [Select]

# cat /etc/apt/apt.conf
PT::Default-Release "stable";
# apt-get -t testing install libc6-dev
Reading package lists... Done
E: The value 'testing' is invalid for APT::Default-Release as such a release is not available in the sources

I think you're missing an 'A'.

[Ceylo]

Oh you're right!! Unfortunately it didn't change anything for apt-get Thanks for pointing out though

Actually I think I'm missing something in /etc/apt/sources.list…
At the moment I have:

Code: [Select]

deb http://debian.mirrors.ovh.net/debian/ wheezy main
deb-src http://debian.mirrors.ovh.net/debian/ wheezy main

deb http://security.debian.org/ wheezy/updates main
deb-src http://security.debian.org/ wheezy/updates main

deb http://pkg.jenkins-ci.org/debian binary/But I don't know what to add so that APT can find testing packages (as it states "The value 'testing' is invalid for APT::Default-Release as such a release is not available in the sources").

[dabbertorres]

Damn, I was hoping that'd fix it. Try making sure 'stable' is in double quotes, ie: "stable".

Yeah, you're right. What you need to do is copy all those lines, paste them below where they currently are, and change all instances of "wheezy" to "testing".

[Ceylo]

Oh man thank you soooooooo much that did it!!!!!! 
Now I'm able to link against SFML without any issue!!

It was just missing the change from "wheezy" to "testing"!

[dabbertorres]

Awesome! Glad it worked!

[BruceJohnJennerLawso]

Apologies for restarting this, but could you specifically describe what you did to get the very last part working? I followed everything right up until the end, but Im still getting

E: The value 'testing' is invalid for APT::Default-Release as such a release is not available in the sources
 

Im running Crunchbang linux.

Hello Bruce,

The error was just that I had forgotten to change the /etc/apt/sources.list file.

Initially I had:

deb http://debian.mirrors.ovh.net/debian/ wheezy main
deb-src http://debian.mirrors.ovh.net/debian/ wheezy main

Which needs to be copy-pasted at the end of your sources.list file and changed to:

deb http://debian.mirrors.ovh.net/debian/ testing main
deb-src http://debian.mirrors.ovh.net/debian/ testing main

Also note that these are the valid URLs for my Linux server hosted by OVH. In your case it may not work. But this is not an issue, just adapt the solution with the URLs you already have in your sources.list file.

Ok, tried that, but still no dice.

What does you apt.conf file look like? I had to create mine as a text file, since it didnt actually exist, although there was a folder called apt.conf.d containing some odd files under /etc/apt.

What exactly did you type into the terminal? I'm not sure I follow what dabbertorres meant by adding the double quotes.

More generally, what exactly is the problem? Am I trying to get at a newer version of the package that SFML 2.1 needs?
