mandelbrot-vanilla.cc not compiling

[ObsidianNA]

Trying to compile the file 'mandelbrot-vanilla.cc' using GCC 7.1.0 on Linux Mint 18 Cinnamon 64-bit. I get the following errors:

cpp_paral/mandelbrot-vanilla.cc: In function ‘double Iterate(double, double)’:
cpp_paral/mandelbrot-vanilla.cc:36:42: error: ‘ESCAPE_RADIUS_SQUARED’ was not declared in this scope
const double escape_radius_squared = ESCAPE_RADIUS_SQUARED;
^~~~~~~~~~~~~~~~~~~~~

const int maxiter = MAXITER;

The compiler doesn't like that ‘ESCAPE_RADIUS_SQUARED’ and 'MAXITER' are not declared, could I get some inside into this issue? Would this program only work on DOS?

These are #defines you must pass on the compiler commandline. For convenience, use the supplied Makefile to build. Example:

$ make mandelbrot-vanilla
g++ -std=c++14 -Ofast -march=native -Wall -Wextra -DMAXITER=8000 -DESCAPE_RADIUS_SQUARED=6*6 -Wno-clobbered -D_GNU_SOURCE=1 -D_REENTRANT -I/usr/include/SDL -lSDL -DPROG_NAME="\"vanilla\"" -pthread -lSDL  mandelbrot-vanilla.cc   -o mandelbrot-vanilla
mandelbrot-vanilla.cc: In function ‘double mylog2(double)’:

     std::uint64_t half_bits    = reinterpret_cast<const std::uint64_t&>(half);
                                                                             ^

     m = reinterpret_cast<const std::uint64_t&>(value);
                                                     ^

     x = reinterpret_cast<const double&>(m);

This program will work on DOS if you can cross-compile SDL2 for DOS. In other words, it will not work on DOS.
