Hi Keshav, thanks for trying efilinux. This compilation error is a known
problem. Fedora (which is running on my development machine) is carrying
patches that update EFI_BOOT_SERVICES with some more function pointers
as specified in the UEFI 2.0 specification - LocateProtocol is one such
function pointer.

Those patches were pushed into the gnu-efi trunk last week, so gnu-efi
3.0l is required to build efilinux if you're not running Fedora.

That possibility has been discussed in the past, and while there
currently is no support for building with anything other than gnu-efi,
patches to build with alternative libraries are welcome. It should
simply be a case of adding alternate definitions for some of the static
inline functions in the header files and adding some Makefile glue.

This project is separate from, but related to, UEFI support in Syslinux.
The Syslinux implementation will likely be based on efilinux, but will
probably not include any efilinux code directly.
