Here is the file :p

Ok try this

Code: Select all

   FILE(GLOB PATH_Candidates
      "C:/Program Files/Emotiv Development Kit*"

This time the compilation aborted.

[gserrier]

That's a progression
Try remove

Code: Select all

#include <windows>

from files
/home/simeon/Logiciels/openvibe-1.0.0/applications/platform/acquisition-server/src/drivers/emotiv-epoc/ovasCDriverEmotivEPOC.h
/home/simeon/Logiciels/openvibe-1.0.0/applications/platform/acquisition-server/src/drivers/emotiv-epoc/ovasCConfigurationEmotivEPOC.h

[DarkPatate]

Arf, another abort ! We will get there :p

[gserrier]

All compilation error are related to error handling.
We can try to remove them to see. It's not clean but if it's work, should be enough for now

in file /home/simeon/Logiciels/openvibe-1.0.0/applications/platform/acquisition-server/src/drivers/emotiv-epoc/ovasCDriverEmotivEPOC.cpp

Remove the block

Code: Select all

	if(_putenv_s("PATH",m_sCommandForPathModification) != 0)
	{
		m_rDriverContext.getLogManager() << LogLevel_Error << "[INIT] Emotiv Driver: Failed to modify the environment PATH with the Emotiv SDK path.\n";
		return false;
	}

and replace the block

Code: Select all

	__try
	{
		m_tEEEventHandle = EE_EmoEngineEventCreate();
		m_ui32EDK_LastErrorCode = EE_EngineConnect();
	}
	__except(EXCEPTION_EXECUTE_HANDLER)
	{
		m_rDriverContext.getLogManager() << LogLevel_Error << "[INIT] Emotiv Driver: First call to 'edk.dll' failed.\n"
			<< "\tTo use this driver you must have the Emotiv SDK Research Edition (or above) installed on your computer.\n"
			<< "\tAt first use please provide in the driver properties the path to your Emotiv SDK (root directory)\n"
			<< "\te.g. \"C:\\Program Files (x86)\\Emotiv Research Edition SDK_v1.0.0.4-PREMIUM\"\n"
			<< "\tThis path will be saved for further use automatically.\n";

		return false;
	}

by

Code: Select all

m_tEEEventHandle = EE_EmoEngineEventCreate();
m_ui32EDK_LastErrorCode = EE_EngineConnect();

Another error :p It stops at 98%, almost !

Hi,

just to chime in: Emotiv Epoc on Linux is not 'officially' supported by OpenViBE (no Linux icon in the Emotiv entry of 'supported hardware' web page).
Getting it to work may require some effort, but it can be feasible. Maybe you are already close! Afaik the core dev team
does not have access to the Emotiv Linux SDK, making it difficult from our side to support Epoc on Linux.

This old post may also be of interest,

viewtopic.php?f=5&t=4277

Btw, I made a personal log entry a few years back that the required mods look relatively simple, but I didn't attempt actual integration for example because we cannot test it without the SDK.


Cheers,
Jussi

Ok, I hope we'll be able to success!
Unfortunately, the github link in your cited post is broken :/

Google finds the following,

Oh sorry, shame on me! However Google is my friend :p

I will try a second installation, in parallel of the first. To continue that of Guillaume after.

Thanks!

I have an error when I want to build the dependencies with the patch

Do you know what can I do?

[gserrier]

Hi,

This is a known issue. Debian made some changes in package name and that leads to that kind of error.
But it has been fix in version 1.0.

Which version are you trying to use?

PS: basically this patch are what we were trying to do.

[DarkPatate]

I followed the Github (and Readme file) instructions in using the command:

Code: Select all

4- Checkout openvibe sources (let's assumer that you are downloading them in your home folder)
	-> cd && svn checkout svn://scm.gforge.inria.fr/svn/openvibe/trunk openvibe

[gserrier]

Okay,
Definitely not the right version .

Use that command to checkout openvibe.
git clone https://gforge.inria.fr/git/openvibe/openvibe.git

in your home directory
