Hi,

Based on the error, it looks like that this sample doesn’t support aarch64 platform.

We are checking this issue internally.
Will update information with you later.

Thanks.

Bhavin_darji · May 2, 2018, 10:07am

I just get it working on JetsonTX2…

ARM support is there in the NvFoundation.h file but still was getting that error.

I don’t know if my solution is proper or not, I have add the following lines in the NvFoundation.h file to get it working

#define _M_ARM
#define __arm__

After adding these lines I am able to build the code but got another error of libAntTweakBar.so.
This library file is generated for x64 or may be x86 architecture so I compiled the source code for TX2 and replace it with generated lib files.
I think NVIDIA DesignWorks Samples:https://github.com/nvpro-samples are only made for windows or linux PC.

AastaLLL · May 3, 2018, 8:04am

Hi,

Root cause is that AARCH64 doesn’t be mentioned in the NvFoundation.h.

After applying a change to this file, there are also some tricks required:
1. Compile AntTweakBar locally and replace libAntTweakBar.so in shared_external/AntTweakBar/lib at master · nvpro-samples/shared_external · GitHub
2. Install vulkan header files from GitHub - KhronosGroup/Vulkan-LoaderAndValidationLayers: **Deprecated repository** for Vulkan loader and validation layers to /usr/include/vulkan

We will get the the change for NvFoundation.h merged and will find somewhere to list the installation instruction for ARM.
Thanks for your feedback.

Bhavin_darji · May 3, 2018, 9:09am

As I told you in my earlier post, I did compile AntTweakBar for the TX2 and also have added the vulkan header files… that is why I am able to build chopper example. And also I tried all nvpro-samples, but not able to build some of the examples.

AastaLLL · May 7, 2018, 8:00am

Hi,

We have fixed the chopper sample.
If you also find other samples cannot build on Jetson, could you share the the sample name with us?

Thanks.

Bhavin_darji · May 8, 2018, 9:16am

hello sir,
Thank you…
From where I can download that example?

these are the examples I am able to compile successfully:
gl_commandlist_basic
gl_commandlist_bk3d_models
gl_dynamic_lod
gl_simple_FBO
gl_ssao
gl_vk_bk3dthreaded
gl_vk_chopper

AastaLLL · May 11, 2018, 6:36am

Hi,

We commit a fix here: https://github.com/nvpro-samples/shared_sources/pull/12
It should be merged after reviewing and the unknown platform error will not occur again.

Thanks.

Bhavin_darji · May 21, 2018, 11:57am

Hello Sir,
What about the other examples?
As I mentioned in my previous comment, I am able to compile certain examples only…

AastaLLL · May 24, 2018, 8:03am

Hi,

We will feedback this issue to our internal team.
Could you share the example blocking you currently?

Thanks.

Bhavin_darji · May 25, 2018, 9:42am

Hello,

These are the examples I am not able to compile:
gl_cadscene_rendertechniques
gl_cl_interop_pingpong_st
gl_cuda_interop_pingpong_st
gl_multicast
gl_occlusion_culling
gl_optix_composite
gl_vk_supersampled
gl_vk_threaded_cadscene

AastaLLL · May 28, 2018, 6:24am

Hi,

As you said, nvpro_sample is designed for x86-based environment.
Some workaround should be implemented before executing on Jetson.

We have verified the nvpro_sample status (identical as yours) and some error we need to check:
Ex. missing header, not declared function or unknown CMake command…

We are co-working with our internal team.
Will update information if we have further progress.

Thanks.

AastaLLL · May 30, 2018, 7:55am

Hi,

We are aware that there are some issue of the public repository and are working on the changes.
Will let you know once we finished.

Thanks.
