Out of box Euclid build of librealsense fails

[MCart5]

I get this error after following the doc/installation.md steps. Also

This also happens with "https://github.com/IntelRealSense/librealsense.git https://github.com/IntelRealSense/librealsense.git"

euclid@EUCLID_xxxx:~$ git clone https://github.com/IntelEuclid/librealsense.git https://github.com/IntelEuclid/librealsense.git euclid_librealsense

Hello weaponeer,

Thank you for your interest in the Intel® Euclid™ Development Kit.I reproduced the issue you are experiencing. But I'll be needing more time to come up with a solution.As soon as I have relevant information I'll post it here.Thank you for your patience.Regards,Andres V.

Andres,

Many thanks -- I tried adding lr200_mm.cpp back to the CMakeLists.txt -- but this caused other issues with Motion related includes. I started over at that point with a new clone, and decided to post -- as others must have found a way around this issue.

Thanks,

MarkC

Hello MarkC,

The reason behind the error message has to do with the fact that the librealsense version on Github has components that are not compatible with the Euclid.There is a version of librealsense that is already installed in the Euclid, it is located in /usr/lib/librealsense. Could you please tell me why are you trying to download the version on Github?I'll be waiting for your response.Have a nice day.Regards,Andres V.

[MCart5]

Andres,

Thanks for the reply, I do appreciate it.

My reason for wanting a local git-based librealsense is to develop with the ability to debug at the source level, and to rapidly pick up fixes and extensions. Our motivation to explore this platform (Euclid) and its possible uses were driven to a great deal by the fact that there was an expectation that the software platform was open. And that it provided in a small package a broad and well integrated suite of sensors that would have otherwise required integration at several levels.

I'm not trying to be difficult here, but to me it does not seem unreasonable to expect the publicly available SDK to build on the target designed to demonstrate it ?

Working around this is acceptable, but I hope you can see my point -- I have too many orphaned platforms in the "drawer of obsolescence" -- and too little time to resuscitate them.

Are there any plans to address this, or suggestions as to how I might approach fixing it myself ?

Hello Mark,

I understand your interest in gaining full control of the software platform. There hasn't been any announcements for a publicly available SDK, so I can't tell you when, or if, it will be available.What I can assure is that I will share your request with the corresponding team.Have a nice day.Regards,Andres V.

Andres,

Thanks -- I hope the developers find a way. Meantime I will try and work around this as I have time.

Cheers,

Hi Weaponeer,

Fortunately I have a workaround for you.

If you go to the CMakeLists.txt and turn off "BUILD_UNIT_TESTS", it should compile fine.

Unless you plan on using those (I know that I haven't ever had the need to use them myself), it shouldn't be a problem.

If you want to build the examples (which aren't exactly as relevant to the Euclid, but can help you better understand librealsense), you can check that on, but make sure to build GLFW first, since it's a dependency.

Meitav,

Thanks ! That worked -- and led me to this:

• cmake .. -DBUILD_EXAMPLES:BOOL=true -DBUILD_UNIT_TESTS:BOOL=false
• Which gave me a clean build with example binaries

Fantastic!

I'm seeing that other people do have so issues with the examples as well, so this will require some digging into the code, but I'm glad it works.

Let us know if you need any further help!
