I have also seen the same error in ubuntu. Is there a solution for this?

newer versions of gromacs don't have the real.h. you can probably install gromacs-2021.tar.gz and it should work. but maybe @DSeiferth could address this.

That's not quite correct. GROMACS still has real.h, but does not install it by default. You should add -DGMX_INSTALL_LEGACY_API=ON flag when configuring GROMACS.

P.S.: Not saying that will solve any other possible compatibility problems.
