compile and link objects with mingw, g++, gcc, ld -

i'm next istructions found here compile os kernel. unfortunely error , don't know do:

gcc boot.o kernel.o -t linker.ld -o kern - nostdlib -nodefaultlibs -lgcc

yields this:

boot.o: in function `start': boot.asm:(.mbheader+0xe): undefined reference `kernel_main' collect2.exe: error: ld returned 1 exit status

everything same except replaced loader.o boot.o (it seems me mistake, loader.o not mentioned anywhere on page).

how can create work?

c++ name mangling calling kernel_main else.

i defined function extern "c" recompiled , opened object. saw actual function name _kernal_main. opened boot.asm file , referenced name.

gcc mingw ld
