[pa-one55]

what is this error ?
i went inside - amrex/amrex-tutorials/GuidedTutorials/HeatEquation_Simple
and did :
mkdir build
cd build
cmake ..
make
and got this error

what do i do now
something similar is happening on gitpod as well.

when i directly did - make
i got the error saying coulnt find - #include <AMReX.H>

Where did you the source code? Could you tell us step by step what you did starting from git clone?

I cannot find any occurrences of computeNewState in amrex or amrex-tutorial.
