Searching the Internet for information on how to build arm toolchain from
scratch I realize that it is very hard to find information about this matter
(and recent one even harder). I will try to fill this lack of information and
try to build toolchain. My main goal is to use a component based on the GNU
public license, and using them in as the newest version as it is possible. What
is toolchain? (according to wikipedia):
In software, a toolchain is the set of programming tools that are used to
create a product (typically another computer program or system of programs).
The tools may be used in a chain, so that the output of each tool becomes the
input for the next, but the term is used widely to refer to any set of linked
development tools.
Requirements
- Cross compiler, I create one using crosstool-ng and describe this process in
previous post. I will use
arm-unknown-linux-gnueabi as entry point
compiler.
$TARGET is defined as my destination directory:
1
|
export TARGET=/home/pietrushnic/sandbox/toolchain
|
Procedure
- Clone linux git repository
1
|
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
|
- Install headers $TARGET is home of our toolchain
1
|
make ARCH=arm INSTALL_HDR_PATH=$TARGET/usr headers_install
|
Libraries (gmp, mpfr, mpc)
1
|
hg clone http://gmplib.org:8000/gmp
|
- create configuration files
1
|
./configure --prefix=$TARGET/arm-x-tools --enable-shared=n --enable-static
|
1
|
make && make check && make install
|
1
|
svn checkout svn://scm.gforge.inria.fr/svn/mpfr/trunk mpfr
|
- create configuration file
1
|
./configure --prefix=$TARGET/arm-x-tools --enable-thread-safe --with-gmp=$TARGET/arm-x-tools --disable-shared --enable-static
|
1
|
svn checkout svn://scm.gforge.inria.fr/svnroot/mpc/trunk mpc
|
- create configuration file
1
|
./configure --prefix=$TARGET/arm-x-tools --with-gmp=$TARGET/arm-x-tools --with-mpfr=$TARGET/arm-x-tools --disable-shared --enable-static
|
1
|
cvs -z 9 -d :pserver:anoncvs@sourceware.org:/cvs/src
|
- login create directory for checkout

LDFLAGS="-Wl,-rpath -Wl,$TARGET/arm-x-tools/lib" ./configure
--build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu
--target=arm-unknown-linux-gnueabi --prefix=$TARGET/arm-x-tools
--disable-nls --disable-multilib --disable-werror --with-float=soft
--with-gmp=$TARGET/arm-x-tools --with-mpfr=$TARGET/arm-x-tools
--with-mpc=$TARGET/arm-x-tools --with-sysroot=$TARGET

To check if everything was made correctly
1
|
ldd $TARGET/arm-x-tools/bin/arm-unknown-linux-gnueabi-ldd
|
It should show that it use library compiled previously by us:
1
|
libz.so.1 => /home/pietrushnic/sandbox/toolchain/arm-x-tools/lib/libz.so.1 (0x00007f0086cc5000)
|
This set gives us a solid base to build the compiler. However, it will be in the
next section.
