make fails: unable to find `experimental` includes

[rpgoldman]

Trying to build plasp on both default and develop branches, I am getting this error from make:

In file included from /Users/rpg/projects/pacman/plasp/lib/pddl/src/pddl/Parse.cpp:1:
plasp/lib/pddl/include/pddl/Parse.h:4:10: fatal error: 'experimental/optional' file not found
    4 | #include <experimental/optional>
      |          ^~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
gmake[2]: *** [lib/pddl/src/CMakeFiles/pddl.dir/build.make:79: lib/pddl/src/CMakeFiles/pddl.dir/pddl/Parse.cpp.o] Error 1
gmake[1]: *** [CMakeFiles/Makefile2:287: lib/pddl/src/CMakeFiles/pddl.dir/all] Error 2
gmake: *** [Makefile:91: all] Error 2

I tried using find and there does not seem to be a directory named experimental in my working copy of plasp. What am I doing wrong? Thanks

Hi rpgoldman, could you tell me which operating system and compiler you are using?

You could try making a fresh conda environment(or something similar) with gcc and cmake. Then, try to install it there following the steps from the other issues. I did this and managed to compile.
