Libfreespace 0.7 is now released!

[Merrill]

The latest version of libfreespace and libfreespace-examples is now available for download.  This version adds support for the new FSM-9 module from Hillcrest Labs which offers full 9-axis fusion with dynamic magnetometer calibration which provides a highly stable and long-term accurate orientation output.  Also the FSM-9 enables user configurable sample rates (up to 250 Hz for full calibrated fusion), the AR/VR smoothing feature, and some new power management and activity classification options.  To download this software, visit the download page at the libfreespace site.  Libfreespace 0.7 supports the FSM-9, the FSM-6, the FSM-USB-2, and the Scoop.  For legacy devices such as the FSRK-2.4G-1 and the FSM-USB-1 you should continue to use libfreespace 0.6 or earlier.

For more information about the FSM-9, visit Hillcrest's FSM-9 product page.

For details about utilizing these new features in libfreespace and migrating your libfreespace 0.6 software to 0.7 (there are a few small API changes), see the migration guide.  Please post any questions or issues to this forum.

Thanks,

Hello Infokade,

Sorry you are having trouble with the libfreespace-examples.  Can you answer a few questions for me?

- Do the libfreespace-examples work for you without modification?

- I do not understand what errors you are receiving based on the information you provided in your recent email.  Please provide build logs and further details about what you are trying to do, and what errors you are receiving.

Thanks,

-Merrill

Hi Merrill

i can  run libfreespace-examples 0.6 but can not run libfreespace-examples 0,7 .. there is no solution in libfreespace-examples0,7 and its complecateted .

according ur post FSM 9 doesnt work with libfreespace-examples0.6 and i cant use libfreespace-examples 0.7 . plz help me to solve my problem

Hello Infokade,

I have created a detailed list of instructions for how to build Libfreespace-examples 0.7 on Windows using Visual Studio 2010.  Please follow these instructions precisely and let me know if you have any issues.  If you do have issues, please provide me the specific error that you are receiving:

How to Build Libfreespace-Examples 0.7 with Visual Studio 2010

1.  Download libfreespace source

              https://launchpad.net/libfreespace/0.7/0.7rc0/+download/libfreespace-0.7.tar.gz

2.  Download libfreespace-examples source

              https://launchpad.net/libfreespace-examples/0.7/0.7rc0/+download/libfreespace-examples-0.7.tar.gz

3.  Download and install cmake

              http://www.cmake.org/files/v3.0/cmake-3.0.1-win32-x86.exe

4.  Download and install the WinDDK v7.1.0

              http://www.microsoft.com/en-us/download/details.aspx?id=11800

5.  Extract the zip files to your working directory (example:  C:\work\)

              So you would have:

                          C:\work\libfreespace-0.7\

                              and

                          C:\work\libfreespace-examples-0.7\

6.  Rename the directories to remove the version numbers:

              So you would have:

                          C:\work\libfreespace\

                               and

                           C:\work\libfreespace-examples\

7.  Open cmake-gui

8.  Under "Where is the source code", choose the directory location where your libfreespace-examples source is (e.g. C:\work\libfreespace-examples\)

9.  Under "Where to build the binaries", choose a directory where you want the solutions created (e.g. C:\work\builds\)

10. Click Configure

11. When prompted to specify the generator, choose Visual Studio 2010 and "Use Default Native Compilers"

12. Confirm the following cmake variable:

       WINDDK_DIR    -   If you installed the WinDDK in the default directory then this should be fine, if it was installed somewhere else choose that directory here

13. Click Configure again

14. The Red bars should now be gone.  Now click Generate

15. There should be a Visual Studio project under the "Where to build the binaries location".  The project will be called libfreespace-examples.sln.  Open this in Visual Studio 2010

16.  Click F7 to build all.  There should now be a group of executables in the Debug folder

HI Dear Merrill

I have a  FSM 9 and several problems with ur OpenSource codes.I did every things that u said but according to the last infokade post have problems and errors like him . i am a windows Programmer and never work with Cmake or some thing like this and i dont know what can i do because i have made a Game and i wanne use Motion Tracker (FSM9 ) and HMD .

NOW i cant use ur libfreespce EXamples 0.7 and because of that cant make my own codes or Dll s or Active x. plz tell me what can i do 

THANK U

[Merrill]

Hello John,

Can you please confirm that you have followed all of my instructions in the previous post to Infokade?  It is very important that you have the prerequisite software installed (WinDDK, etc) and that the directory structure is laid out as described in that post.  All of this information is in the README for the software as well.  CMake is very easy to use, and the steps that I listed in that email detail the procedure for using CMake.

Thanks,

Hi

As i said i am a C# Programmer and wanne use fsm9 in my game . because of that  i need ur help to answer my questions. my questions are :

1 - can i use libfreespace.dll with out using libfreespace examples 0.7 ?

2 - how can i use libfreespace examples0.7 and c# togather?
Regards

john

[Merrill]

Hi John,

Libfreespace.dll is separate from the libfreespace-examples.  The libfreespace-examples package is a set of example applications that utilize the libfreespace.dll, but you can certainly write your own applications that utilize this DLL.

There is not an official C# wrapper for libfreespace 0.7, but some other customers have been successful in writing their own C# wrappers for this so I know it is possible.

I hope this helps, thanks.
