Hi everyone, I am trying to compile this program (https://github.com/dincarnato/draco). I arrive until the step were I type make -j4 but I get this error:

[  0%] Building CXX object src/CMakeFiles/args_generate.dir/args_generate.cpp.o

Any idea about how to solve it?

Thank you very much!

please understand that we are not ignoring you. The developer of DRACO does not work in the lab anymore, so it takes time for him to go through the code and understand the issue and fix it.

For sure, no offense because I ask also in here. I understand that this things spend it's time to find the error and I am very grateful for answering me in GitHub forum. Asking here is just to look for anyone that maybe could also help

string_view: No such file or directory

the compiler needs a file string_view.h or string_view.hh . This header requires a c++ compiler handling c++17 ( https://en.cppreference.com/w/cpp/header/string_view).

see https://stackoverflow.com/questions/64141078/compile-c-file-in-linux-terminal-string-view-no-such-file-or-directory

You'll need to update your compiler. std::string_view is not available in GCC until version 7.
