-From rEFIt to rEFInd
-====================
-
-rEFInd is derived from rEFIt (http://refit.sourceforge.net), but the two
-programs support different build environments. rEFIt was created with
-Intel's EFI Application Toolkit
-(http://www.intel.com/technology/efi/toolkit_overview.htm) or TianoCore's
-EFI Toolkit (https://efi-toolkit.tianocore.org), along with Microsoft's
-Visual C compiler.
-
-Compiling the source code provided on the rEFIt site under Linux never
-worked for me, although the documentation claimed it would. Apparently
-other Linux developers have run into the same problem; Debian provides a
-rEFIt package (http://packages.debian.org/sid/refit) that includes
-extensive patches to enable the program to compile under Linux using the
-GNU-EFI package (http://sourceforge.net/projects/gnu-efi/). Although
-GNU-EFI is less sophisticated than recent versions of TianoCore's toolkit,
-GNU-EFI is my preferred environment because it's provided with many Linux
-distributions and it was easy to get started with rEFInd development by
-using GNU-EFI and the Debian rEFIt package as a starting point.
-
-Over time, though, I've found that the recent TianoCore EDK2 toolkit has
-its advantages. Two features, in particular, require the TianoCore EDK2
-toolkit:
-
-- The EFI filesystem drivers, added with rEFInd 0.4.0. This requirement is
- a consequence of the derivation of the drivers, which is via VirtualBox
- and the Clover boot loader, both of which are based on EDK2.
-
-- The legacy BIOS boot feature for UEFI-based PCs. EDK2 is needed in this
- case because of features unique to that environment. Note that the legacy
- BIOS boot feature for Macs works when rEFInd is built via either GNU-EFI
- or the TianoCore EDK2.
-
-For these reasons, effective with rEFInd 0.4.6, I've switched the primary
-build environment from GNU-EFI to TianoCore EDK2. The rEFInd binary itself
-still builds via GNU-EFI, but you must pass the "gnuefi" build target to
-make in order to build in this way, and the resulting binary can't boot
-BIOS-based OSes on UEFI PCs.
-
-I've dropped ancillary programs, such as the gptsync program, from rEFInd.
-You can still use these tools with rEFInd, but you'll need to install them
-separately.
-
-
Requirements
============
To compile rEFInd, you'll need the following:
* A Linux installation. Note that this installation does NOT need to be
- EFI-based. It can be 32- or 64-bit, but unless you use a cross-compiler
- (which I've not tested), it must be the appropriate bit width for your
- EFI implementation. (Normally that means 64-bit.) If you don't normally
- run Linux, you can run it in a VirtualBox or similar virtual machine. (I
- describe some unsupported non-Linux build options shortly.)
-
-* A standard set of Linux development tools, based on GCC.
+ EFI-based. It can use IA32 (aka x86, i386, or other things), X64 (aka
+ x86-64, AMD64, or EM64T), or AA64 (aka AARCH64 or ARM64), but unless you
+ use a cross-compiler, it must use the same CPU type and bit depth as your
+ EFI implementation. (Normally that means 64-bit X64.) If you don't
+ normally run Linux, you can run it in a VirtualBox or similar virtual
+ machine. (I describe some unsupported non-Linux build options shortly.)
+
+* A standard set of Linux development tools, based on GCC. (I've tried
+ using clang 3.4 under Ubuntu, with partial success. The main rEFInd
+ binary, gptsync, and some drivers compile successfully; but only gptsync
+ runs normally. The drivers I've tried and the main rEFInd binary crash.)
* One of the following:
* The TianoCore EDK2 package
- (http://sourceforge.net/projects/tianocore/). I've tested using the
- UDK2010.SR1 and UDK2010.SR1.UP1 variants
- (http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=UDK2010),
- which are "frozen," rather than the main EDK2 development branch, which
- is changing as the developers add features, fix bugs, and so on. Using
- TianoCore EDK2 is supported in rEFInd version 0.4.3 and later (0.4.0
- and later for the filesystem drivers only). See below for TianoCore
- setup instructions.
+ (http://sourceforge.net/projects/tianocore/). I initially used the
+ UDK2010 package and others in that series, but beginning with rEFInd
+ 0.8.2, I've been using UDK2014
+ (http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=UDK2014).
+ All of the UDK are "frozen," rather than the main EDK2 development
+ branch, which is changing as the developers add features, fix bugs, and
+ so on. See below for TianoCore setup instructions.
* The GNU-EFI package (http://sourceforge.net/projects/gnu-efi/). You can
install this from a package called "gnu-efi"; however, rEFInd relies on
- features that were added in (I think) 3.0l to provide driver-loading
- capabilities. The versions I've used and that work are 3.0p and 3.0q.
- As of 5/2012, most Linux distributions seem to deliver rather elderly
- versions of GNU-EFI, so you may need to download the latest source
- code, compile it, and install it locally. Since rEFInd version 0.2.7,
- the Makefiles assume this (see below). The legacy BIOS boot support on
- UEFI-based PCs doesn't work when GNU-EFI is compiled under GNU-EFI, so
- as of rEFInd 0.4.6, GNU-EFI is no longer the primary build environment,
- although it's easier to set up on a Linux system.
+ features that were added sometime between version 3.0s and 3.0u, so I
+ recommend using 3.0u (or conceivably later). You should check your
+ GNU-EFI version number; you may need to download the latest source
+ code, compile it, and install it locally. The Makefiles assume a
+ GNU-EFI package installed via a package manager. If you install from
+ source code, you may need to adjust those Makefiles' paths.
+
+Of the two toolkits, I prefer to use TianoCore because it produces binaries
+that are about 5-30KiB smaller than those made by GNU-EFI, and I can easily
+build 32-bit binaries on my 64-bit Linux installations. Also, I've had
+problems on a 32-bit Mac Mini with the drivers produced by GNU-EFI hanging
+the system. (I haven't encountered this problem on UEFI-based PCs.) That
+said, the TianoCore EDK2 package is much harder to install, so you may
+prefer to use GNU-EFI unless you have a specific need for the TianoCore
+toolkit. Automated build tools like the OpenSUSE Build Service (OBS) and
+the Ubuntu Personal Package Archive (PPA) mechanism don't yet support
+TianoCore.
It's possible to use a non-Linux platform to compile rEFInd. To the best of
my knowledge, the rEFInd code doesn't rely on anything Linux-specific in
Preparing Your Development Kit
==============================
-If you want to build the rEFInd binary but not the drivers, if you don't
-care about booting BIOS-based OSes on UEFI PCs, and if you're using Linux,
-GNU-EFI is the easiest way to do the job. I don't describe its setup here
-because it's likely to be fairly easy. If your distribution provides a
-recent enough version, you should be able to install a package called
-gnu-efi and be done with it. If not, you'll need to download the source
-code tarball, build it, and install it. This process is fairly typical of
-Linux packages. Read the GNU-EFI documentation if you need help. If you're
-using GNU-EFI, you can skip the rest of this section.
-
-To build the EFI drivers, or if you want support for booting BIOS-based
-OSes on UEFI PCs, the TianoCore toolkit is required. You might also want to
-use it if you have problems with GNU-EFI or if you want to build rEFInd on
-a non-Linux platform. Unfortunately, the TianoCore toolkit is weird by
-Linux programming standards. It's also quite large -- it's intended as a
-means to develop a complete EFI firmware implementation, so it contains
-much more code than is needed to develop standalone EFI applications. I
-don't know of any Linux distribution packages for it in RPM, Debian package
-file, or other formats; you MUST install the kit from source code using its
-own unusual compilation procedure. The installation documentation also
-omits at least one step and is a bit unclear about others. Here's how I

Compiling rEFInd
3) Change into the archive's main directory. You should see several files
including this BUILDING.txt file and several subdirectories such as
- "refind", "libeg", and "include".
-
-4) Type "make gnuefi" to build with GNU-EFI, or either "make" alone or
- "make tiano" to build with TianoCore EDK2. With any luck, rEFInd will
- compile without error, leaving the "refind_ia32.efi" or "refind_x64.efi"
- file, depending on your platform, in the "refind" subdirectory.
+ "refind", "libeg", "mok", "filesystems", and "include".
+
+4) Type "make" to build rEFInd. The Makefile checks for the TianoCore
+ toolkit and tries to use it if it's present. If both toolkits are
+ installed, you can specify the toolkit name -- "make gnuefi" to build
+ with GNU-EFI, or either "make tiano" to build with TianoCore. With any
+ luck, rEFInd will compile without error, leaving the "refind_ia32.efi",
+ "refind_x64.efi", or "refind_aa64.efi" file, depending on your platform,
+ in the "refind" subdirectory. This same step builds the
+ "gptsync_ia32.efi", "gptsync_x64.efi", or "gptsync_aa64.efi" program
+ file, in the "gptsync" subdirectory. (When cross-compiling with
+ TianoCore, "gptsync_aa64.efi" is not built because the cross-compiler
+ failed for me. Since gptsync is likely to be useless on ARM64, this is
+ no great loss.) If you want to build IA32 binaries on an x86-64 (X64)
+ system, type "ARCH=ia32 make". Similarly, you can specify "ARCH=aarch64"
+ to cross-compile for ARM64. This works only if you're using the
+ TianoCore build kit, and only if you set TARGET_ARCH to the appropriate
+ value in target.txt when you set up the TianoCore toolkit. If you plan
+ to build multiple architectures, be sure to copy the .efi file for the
+ first build out of the refind subdirectory before building the second
+ architecture.
5) The default build process does NOT build the filesystem drivers. If you
want to build them, you must type "make fs" in the main rEFInd source
- directory. The result is filesystem drivers in the filesystems
- subdirectory, and also copies placed in the drivers subdirectory. You
- must install the TianoCore EDK2 to build the drivers.
+ directory. This command builds with the TianoCore toolkit if it's
+ available and with GNU-EFI if it's not. Alternatively, you can type
+ "make fs_gnuefi" to build with GNU-EFI or "make fs_tiano" to build with
+ TianoCore. (You can prepend "ARCH=ia32" or "ARCH=aarch64" to
+ cross-compile for those architectures, as when building the main rEFInd
+ binary.) The result is filesystem drivers in the filesystems
+ subdirectory, and also copies placed in the drivers_{arch} subdirectory.
If rEFInd doesn't compile correctly, you'll need to track down the source
of the problem. Double-check that you've got all the necessary development
tools installed, including GCC, make, and either GNU-EFI or TianoCore EDK2.
-You may also need to adjust the Makefile, Make.common file, or Make.tiano
-file for your system. (The main Makefile controls the process for both
-toolkits, while Make.common holds GNU-EFI options and Make.tiano holds
-TianoCore options.) The most likely thing you'll need to change is the path
-to the various GNU-EFI include files and libraries. Since rEFInd 0.2.7, the
-default Make.common file includes the following definitions:
-
-EFIINC = /usr/local/include/efi
-GNUEFILIB = /usr/local/lib
-EFILIB = /usr/local/lib
-EFICRT0 = /usr/local/lib
-
-If you've installed GNU-EFI from a distribution's package, you may need to
-remove "local" from those paths, and perhaps change references to "lib" to
-"lib64". As noted earlier, though, as of 5/2012, most distributions provide
-out-of-date GNU-EFI implementations that will not work with rEFInd 0.2.7
-and later.
+You may also need to adjust the Makefile or Make.common file; or possibly
+Make* files in code subdirectories. (The main Makefile controls the process
+for both toolkits, while Make.common holds most common options.) The most
+likely thing you'll need to change is the path to the various GNU-EFI
+include files and libraries. Since rEFInd 0.6.2, the default Make.common
+file includes the following definitions:
+
+EFIINC = /usr/include/efi
+GNUEFILIB = /usr/lib
+EFILIB = /usr/lib
+EFICRT0 = /usr/lib
+
+If you've installed GNU-EFI from source code, you may need to add "local"
+to those paths, as in "/usr/local/include/efi". You might need to change
+references to "lib" to "lib32" or "lib64" on some systems. Recall that you
+need at least GNU-EFI version 3.0l to build rEFInd, and until very
+recently, most distributions provided out-of-date versions of this package.

When I tried to compile rEFInd under Ubuntu 12.04 (i386) using GNU-EFI,

Compiling the EFI Filesystem Drivers

Oracle's VirtualBox project (https://www.virtualbox.org) and the Clover
boot loader project (https://sourceforge.net/projects/cloverefiboot/),
which I used as the source for this build.
+
+Adding Support for Network Boot
+===============================
+
+rEFInd provides EXPERIMENTAL support for booting over the network using
+iPXE (http://ipxe.org) as a means to receive the payload. In order to
+enable this feature you'll want to follow these instructions:
+
+* cd net/
+* make source
+* make netboot
+* copy bin/ipxe.efi and bin/ipxe_discover.efi to the EFI volume at EFI/tools/
+
+Note that you may need to install additional development packages, such as
+libiberty-dev and binutils-dev, in addition to those needed to build rEFInd
+itself.
+
+My own tests show this support to work under optimal conditions; however,
+architecture (EFI vs. BIOS) detection may not work, and some computers will
+hang or won't retrieve boot files from the network. For these reasons, this
+support is disabled by default in rEFInd, and I do not provide iPXE
+binaries.
