error in make: rasterise_egl.cu.o fail about dirt HOT 7 CLOSED

@threedlife Sorry, I misread where the error was occurring. In fact, I'm not sure why this problem is happening (I can't reproduce it); it may be a bug using that exact version of nvcc with that exact version of gcc. You could try upgrading nvcc, if possible.

Alternatively, try moving the definition of struct Vec3 { ... }; (rasterise_grad_egl.cu, lines 63-101) to just above the function assemble_grads that it's currently inside (so put the struct at line 55). That shouldn't affect the functionality, but makes the code 'easier' for the compiler.

Update: The error was in
tensorflow/include/absl/strings/string_view.h(496): error: constexpr function return is non-constant

The error is described here, and there are workarounds.

Soory... I'm new foir Cmake. Could you tell me your solution?

following up this thread, i came across similar issues while building Dirt from source.

Any idea how to resolve this? Appreciate it!

@threedlife This seems to be a separate issue, maybe specific to your cuda compiler version. What version of gcc, nvcc, and tensorflow are you using?
As a hack to fix it, try changing constexpr to just const at dirt/csrc/rasterise_grad_egl.cu line 62

Thanks @pmh47

I using CUDA 8.0, nvcc v8.0.61, gcc 5.4.0, python 2.7.12, cmake 3.14.3, and tensorflow 1.4.

I didn't found constexpr in line 62 of rasterise_grad_egl.cu. Might it be somewhere else to change?

@pmh47 moving struct Vec3 above assemble_grads worked! Thanks.
