Mingw GCC Undefined references to LIB EFI

For the past couple days I've been trying to get Mingw GCC Working with GNU-EFI, Whenever I try to compile using function from libefi.h I get errors:

Code:

/usr/lib/gcc/x86_64-w64-mingw32/13.1.0/../../../../x86_64-w64-mingw32/bin/ld: /tmp/ccUyeC4u.o:main.c:(.text+0x1c): undefined reference to `InitializeLib'
/usr/lib/gcc/x86_64-w64-mingw32/13.1.0/../../../../x86_64-w64-mingw32/bin/ld: /tmp/ccUyeC4u.o:main.c:(.text+0x2b): undefined reference to `Print'

This is my Makefile

Code:

gcc:
   x86_64-w64-mingw32-gcc main.c \
   -std=c17 \
   -Wall \
   -Wpedantic \
   -mno-red-zone \
   -ffreestanding \
   -nostdlib \
   -I /usr/include/efi \
   -I /usr/include/efi/x86_64 \
   -L /usr/lib
   -Wl,--subsystem,10 \
   -e efi_main \
   -o main.efi

I apologize for the delay in approving your post.

GNU-EFI is not intended to be used with Mingw: It is a build system for using an ELF toolchain to create EFI binaries.

You are referencing library functions from the included EFILIB - if you want to use these functions outside of GNU-EFI, you must build it separately from source and then link with it.
