The Apache-ANT program is a build tool that uses XML-based project files.
Similar to Makefiles, these project files may contain multiple targets. Most
build.xml files in EDK II are auto-generated; any edits performed on the
build.xml files will be overwritten the next time build is executed.
build.xml files will be overwritten by the next build.
Pre-defined targets in the build.xml file include:

A Word on GCC tool chain

A Word on the GCC Tool Chain
----------------------------
EDK II will not compile with a standard Linux gcc tool chain. While Linux
distributions are usually based on ELF, EDK II requires a version of gcc
that is configured to produce PE-COFF images. You will find a script in
edk2/Tools/gcc that will download, configure, compile, and install a gcc
4.X cross-compile tool chain for EDK II development. It has support for
the IA32 architecture. It can be built and run on Cygwin, Linux, and many
other POSIX compliant host operating environments. There are a few tools
that you will need on your host computer in order to compile the tool
chain. Among them are bash, gcc, gmake, curl (or wget).

subdirectory (i.e. EdkNt32Pkg).) The SPD file is further explained in “EDK II
Build and Packaging Architecture Specification.”
B) Module Surface Area Definition (MSA) files. A description of a module's
surface area, with all module specific default flags and features specified.
Refer to the "Module Surface Area Architecture Specification" for additional
details. The MSA is further explained in the "EDK II Build Packaging Architecture
Specification" document.
For additional details, see the "EDK II Module Surface Area Specification" and
the "EDK II Build and Packaging Architecture Specification."
C) Framework Platform Description (FPD) files. A description of a platform's
surface are, including a list of modules that are needed by the platform. To
support individual module builds, developers are not required to provide
information about specific flash devices, nor flash device layout. There are
specific sections in the FPD file that do control aspects of the build, such
information about specific flash devices, nor flash device layout.
Specific sections in the FPD file control aspects of the build, such
as the Supported Architectures and Build Targets, as well as the tool flags
that are used to create the binary files. A valid platform file can specify
zero or more modules, so individual modules can be compiled within the context
of a platform (FPD) definition.
D) Platform Configuration Database (PCD). A platform database which contains a
variety of current platform settings or directives by which a driver or
application can interact with. The PCD is defined by the PCD_Protocol (This is
further explained in the "Platform Configuration Database Infrastructure
Description" document.

E) Library Class. A library class is a logical grouping of similar functions.
When developing components, the module surface area declares the class of
libraries that can be used by the component. The MSA and SPD files can specify
a recommended instance of the library that a platform integrator may select,
however this is only a recommendation. The PI may choose to select a different
library instance to be used during compilation/linking. All library type modules
must include header files in their distribution package, as well as their MSA
files. Components, on the other hand, need only provide an MSA and either source
or binary files when distributing packages. The Library Classes are further
explained in the "EDK II Build and Packaging Architecture Specification"
document.
