On GNU/Linux, you also need:
To build GRUB's graphical terminal (gfxterm), you need:
-* FreeType 2 or later
+* FreeType 2.1.5 or later
* GNU Unifont
If you use a development snapshot or want to hack on GRUB you may
need the following.
-* Python 2.5.2 or later
-* Autoconf 2.60 or later
-* Automake 1.10.1 or later
-* Autogen 5.10 or later
+* Python 2.6 or later
+* Autoconf 2.63 or later
+* Automake 1.11 or later
Prerequisites for make-check:
2. Skip this and following step if you use release tarball and proceed to
step 4. If you want translations type `./linguas.sh'.
- 3. Type `./autogen.sh'.
+ 3. Type `./bootstrap'.
+
+ * autogen.sh (called by bootstrap) uses python. By default the
+ invocation is "python", but it can be overridden by setting the
+ variable $PYTHON.
4. Type `./configure' to configure the package for your system.
If you're using `csh' on an old version of System V, you might
If build and host are different man pages are not generated.
As an example imagine you have a build system running on FreeBSD on sparc

+Normally, for building a GRUB on amd64 with tools to run on amd64 to
+generate images to run on ARM, using your Linux distribution's
+packaged cross compiler, the following would suffice:
-./configure BUILD_CC=gcc BUILD_FREETYPE=freetype-config --host=amd64-linux-gnu
-CC=amd64-linux-gnu-gcc CFLAGS="-g -O2" FREETYPE=amd64-linux-gnu-freetype-config
---target=arm --with-platform=uboot TARGET_CC=arm-elf-gcc
-TARGET_CFLAGS="-Os -march=armv6" TARGET_CCASFLAGS="-march=armv6"
-TARGET_OBJCOPY="arm-elf-objcopy" TARGET_STRIP="arm-elf-strip"
-TARGET_NM=arm-elf-nm TARGET_RANLIB=arm-elf-ranlib LEX=gflex
+ ./configure --target=arm-linux-gnueabihf --with-platform=efi
