Here lie my first attempts at building UEFI-executable software. You will need a GNU/Linux machine that supports building ELF objects for your target system (which POSIX-UEFI's toolchain converts into PE executables for us).
Clone our upstream submodules:
git submodule update --init --recursive
Build POSIX-UEFI:
make -j$(nproc) -Cposix-uefi uefi
Demos can be compiled by the names of their directories.
For instance, to compile the hello demo, simply run:
make hello
If you have a GNU/Linux system with KVM enabled, you can run a demo like so:
./qemu_test.sh hello
The above will put you at Tianocore's EFI shell. Simply type the following (and press enter) to run the demo:
FS0:\hello.efi
