C / 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

okay thank you. I thought my resolution would take the same effect - but it doesn't.

Hi, after updating (C)SFML I get an known error but the known solution with -l gcc_s -l gcc didn't work any more

Hi, I have written a little program using sfml. Now I like to install it on a fresh Ubuntu 16.01 with cmake/make but i get an error which I don' get fixed.

chris@Ubuntu-PC:~/Programme/sfml-build$ cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr/local -DCMAKE_BUILD_TYPE=release ../sfml
CMake Error at FindSFML.cmake:359 (message):
    Could NOT find SFML (missing: SFML_SYSTEM_LIBRARY SFML_WINDOW_LIBRARY      
    SFML_NETWORK_LIBRARY SFML_GRAPHICS_LIBRARY SFML_AUDIO_LIBRARY)
 

I tried some solutions like setting the  SFML_ROOT but it doesn't work. Do I have to set it to the header direcory or to another directory?

If you need more details I will post it next time

Hi,

after updating Ubuntu 14.01 to Ubuntu 16.01 xenial with KDE 4.14 I get this terminal error :

root@PC-Ubuntu:/home/user/test# ./TEST
Failed to open X11 display; make sure the DISPLAY environment variable is set correctly
 

If i run the code in Eclipse the window open correctly.

Some additional Informaion:

root@PC-Ubuntu:/home/user/test# echo $DISPLAY
localhost:10.0

root@PC-Ubuntu:/home/user/test# grep X /etc/ssh/sshd_config
X11Forwarding yes
X11DisplayOffset 10
 

Any idea how to fix?

Adding CSFML Library search path and SFML include path solved my problem. Thank you very much for your support eXpl0it3r!!

Hm i tried both. First csfml and first sfml libs

... but the failure is the same.

Any other idea?

okay my mistake. i read it again and took the workaround. After this the last error is the following:

Any solution?

thank you. But I don't understand the solution. How could I add -lgcc_s -lgcc at the end of the g++ command that links the shared library?

How could i link SFML statically against CSFML with Eclipse? Or how could I link SFML with eclipse?

I added sfml-graphics, sfml-system and sfml-window to settings->linker->libraries and now the console output of eclipse changed to:

C / Re: CMAKE failure

I found the solution.

1) Copy FindSFML.cmake from SFML-Master/cmake/ to CSFML-Master/
2) add

set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/" ${CMAKE_MODULE_PATH})

to CSFML-Master/src/SFML/CMakeLists.txt

My next question: Why isn't this write down in the csfml-documentation for ubuntu-beginner like me?

Thank you.

I don't know very much about cmake files. Do you have a snipped of code which i have to paste in the skript?
