pbr-visualizer embree compiling error

[ttsesm]

Hi @gerardsimons I am trying to compile the pbr-visualizer and I am getting the following error:

../pbr-visualizer/common/simd/sseb.h:108:29: error: could not convert ‘_mm_shuffle_epi32(a, ((((i3 << 6) | (i2 << 4)) | (i1 << 2)) | i0))’ from ‘__m128i’ {aka ‘__vector(2) long long int’} to ‘const embree::sseb’
  108 |     return _mm_shuffle_epi32(a, _MM_SHUFFLE(i3, i2, i1, i0));
      |            ~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |                             |
      |                             __m128i {aka __vector(2) long long int}

Do you know how I could solve it?

I am using Embree 3.9 and GCC 9.3.0 and I am on a linux system.

Thanks.

Hi there! So sorry about the delay. I haven't looked at this code for a while. Are you still facing this issue? I can try and run it again for you. What C++ version are you using? Though the most likely candidate seeing how old this code is is that it's not compatible with the newer version of EMBREE.

No worries, as I've mentioned I am using GCC 9.3.0 so it should support C++14 which is a requirement. Yes, I think the issue has to do with the new EMBREE lib version. I tried to make some changes in the common folder, but I didn't manage to make it work at the end. I am not sure how easy would be to update the code for the new EMBREE lib version.

I think it would be easier to try older versions of EMBREE:

It's a bit silly that I did not list the exact version of EMBREE we rely on. @TobiasRp Do you remember which exact one we used? Otherwise go back to around the time that this was last updated... Sorry that I cannot help more at this time. Will try to find some time in the future to try and upgrade.

@gerardsimons thanks for the feedback. I will try to check with an older version of EMBREE once I find some time.
