Make about freeviewsynthesis HOT 10 CLOSED

hi, i checkouted this error carefully, and found that perhaps there was something wrong in "return" of function 'get_sampling_map'.
return {create_arrayN<float>(maps, {n_views, patch_height, patch_width, 2}), create_arrayN<float>(valid_depth_masks, {n_views, 1, patch_height, patch_width}), create_arrayN<float>(valid_map_masks, {n_views, 1, patch_height, patch_width})};
the return type should be 'std::tuple', i am not sure '{ }' can create a tuple, so i use 'std::make_tuple' instead, and it finally succeeded. the code is like this:
return std::make_tulpe(create_arrayN<float>(maps, {n_views, patch_height, patch_width, 2}), create_arrayN<float>(valid_depth_masks, {n_views, 1, patch_height, patch_width}), create_arrayN<float>(valid_map_masks, {n_views, 1, patch_height, patch_width}));

You can change in line 37 in common.h from {data.size()} to {long(data.size())}`. This should fix your error.

What system are you on, what compiler are you using? Could you maybe post your cmake output?

i am using Ubuntu 16.04.4 LTS. And this is output:

I suspect that your compiler version is too old, but I can not currently set up a similar env to test. Could you try to try a more recent compiler, not sure which version ships with ubuntu 16.04. Note, I tested only with Ubuntu 18.04 and macOS.

I see. That is due to the compiler version. A return {...} requires a C++17 compiler, if the compiler only supports C++11,14 you need to write std::make_tuple as you suggested.

hello, I am on a C++ 17 supported compiler, I still got that same error mentioned, I tried making tuple, it still gives me error.

@griegler @Jonlysun can you please help

Hello @griegler after compile it succesfully, I try g++ -std=c++11 main.cpp but got errors like below:

undefined reference to `Py_GetVersion'
undefined reference to `PyExc_ImportError'
undefined reference to `PyErr_Format'
undefined reference to `PyExc_ImportError'
undefined reference to `PyErr_SetString'
undefined reference to `PyExc_ImportError'
undefined reference to `PyErr_SetString'

@visonpon If you already compiled it sucessfully, why are you running g++?

@griegler got it, thanks~
