SFML works on FreeBSD very good

[ccbsd]

Edit: I am sorry for this edit. SFML works on FreeBSD very good after years.

When I compile SFML 2.0 in my FreeBSD 8.2 with cmake:

Code: [Select]

CMake Warning at cmake/Config.cmake:20 (message):
   Unsupported operating system
 Call Stack (most recent call first):
   CMakeLists.txt:14 (include)



 CMake Error at CMakeLists.txt:190 (install):
   install FILES given no DESTINATION!

Part of the cmake/Config.cmake file:

Code: [Select]

# detect the OS
 if(${CMAKE_SYSTEM_NAME} MATCHES "Windows")
     set(WINDOWS 1)
 elseif(${CMAKE_SYSTEM_NAME} MATCHES "Linux")
     set(LINUX 1)
 elseif(${CMAKE_SYSTEM_NAME} MATCHES "Darwin")
     set(MACOSX 1)

Do you really don't want SFML to support FreeBSD?

Edit: I am sorry for this edit. SFML can be built on FreeBSD without suspense. It just run better. SFML works on FreeBSD very good after years.

cmake/Config.cmake

     19 elseif(${CMAKE_SYSTEM_NAME} STREQUAL "Linux")
     20     set(SFML_OS_UNIX 1)
     21     if(ANDROID)
     22         set(SFML_OS_ANDROID 1)
     23         # use the OpenGL ES implementation on Android
     24         set(OPENGL_ES 1)
     25     else()
     26         set(SFML_OS_LINUX 1)
     27         # don't use the OpenGL ES implementation on Linux
     28         set(OPENGL_ES 0)
     29     endif()
     30 elseif(CMAKE_SYSTEM_NAME MATCHES "^k?FreeBSD$")
     31     set(SFML_OS_FREEBSD 1)
     32     # don't use the OpenGL ES implementation on FreeBSD
     33     set(OPENGL_ES 0)
 

And I wish more other BSD supports. Bitrig, NetBSD, OpenBSD, ...

In fact SFML supports FreeBSD, it's just the CMake file which is incomplete.

I see, thank you.

[ccbsd]

but I don't know how to modify the cmake files.

[Laurent]

You don't have to, it's already fixed.

It was not tested so... I hope it really works

[ccbsd]

I downloaded LaurentGomila-SFML-bindings_removed-98-g78a625d.tar.gz just now and build it. I still failed to build it.

Code: [Select]


 elseif(${CMAKE_SYSTEM_NAME} MATCHES "FreeBSD")
     # FreeBSD compile path is the same as Linux
     set(LINUX 1)

FreeBSD is not Linux.

Which file defines JSIO*, ABS_*, js_event_* ?

[Laurent]

I downloaded LaurentGomila-SFML-bindings_removed-98-g78a625d.tar.gz

This looks like an old revision (bindings_removed is a tag that I set when I removed bindings from the main repository).

FreeBSD is not Linux.

Yeah, I know... but the build configuration is the same on both. That's why I've put a comment to explain this.

...many errors with joystick API...

Ok, here is the interesting stuff
The joystick API on FreeBSD is undocumented and I was waiting for someone to help me for implementation and tests. Would you like to help?

I 'd like. How to do? (I have some level c and c++ skills. But I have a frew system and project build skills).

[Laurent]

First, we need to find documentation for the joystick API on FreeBSD. It should be close the Linux one, but without a doc we can't do anything.

Then with a doc I think I'll be able to fix the code blindly, and you would test it for me.

So... do you know where I could find the documentation of the FreeBSD joystick API?

sounds interesting. I will have a try.

Now we need some functions to make use of these constants

After searching a little bit I found that most of the libraries that implement joystick handling (like SDL) rely on uhid directly on FreeBSD. That's... raw.

[ccbsd]

Maybe ois is a solution, I am not sure. A friend told me.

Object Oriented Input System (OIS) is meant to be a cross platform, simple solution for using all kinds of Input Devices (Keyboards, Mice, Joysticks, etc) and feedback devices (e.g. force feedback). Written in C++ using Object Oriented Design pattern

http://sourceforge.net/projects/wgois/
ois is in FreeBSD ports tree:
/usr/ports/devel/ois/

I don't want to use a high-level library for this, but I can have a look at their source code.

They have files for Win32, Mac, Linux, iPhone but I can't find what they use for FreeBSD.

[ccbsd]

I am sorry that it's hard for me to do something for SFML. It's a pity that FreeBSD users can't use SFML 2.0 now.
