A very simple Brainfuck compiler made for windows and x64 NASM
First you are going to need to install NASM and mingw-w64. Once you have them configured correctly it should be as simple as running
g++ main.cpp -o bfcompiler.exe
You can compile brainfuck code to assembly like this:
bfcompiler.exe <path to your brainfuck file>
The compiler will always output the assembly in the file out.asm
Now you need to generate the .obj file, link it to the c standard library and turn it into an .exe file.
If you are using the tools I previously linked and they are installed correctly this should work:
nasm -f win64 out.asm
gcc out.obj -o <your desired executable name>.exe
