Build Steps

Compile E code in the IDE

2. Open source/elkernel.e in the IDE
3. Compile the code via 'Statically Compile(靜態編譯)'
4. Compiler fails with a Win32 COFF file, Do not delete it.

Bootable Floppy

1. Open build/elKernel.sln in the Visual Studio
2. Set floppy.mk as startup project
3. Build (Ctrl+Shift+B)

How To Debug

Use QEMU to debug the kernel

  @echo off
  set PATH=%PATH%;YOUR_QEMU_INSTALLATION
  qemu-system-i386 -gdb tcp::23333 -fda ./elkernel.img

Execute the batch file, then attach to the QEMU instance.
