HOWTO create an LLVM crosstool from x86_64/Linux to ARM/Linux
|
||
|
|
=============================================================
|
||
|
|
|
||
|
|
1. % llvm/utils/crosstool/create-snapshots.sh
|
||
|
|
|
||
|
|
This will create llvm-[REV_L].tar.bz2 and llvm-gcc-4.2-[REV_G].tar.bz2,
|
||
|
|
where:
|
||
|
|
REV_L is the revision at which "llvm" was checked out, and
|
||
|
|
REV_G is the revision at which "llvm-gcc-4.2" was checked out
|
||
|
|
|
||
|
|
Note that REV_L might REV_G might not be the same revision.
|
||
|
|
|
||
|
|
2. Download CodeSourcery toolchain. The exact location depends on your
|
||
|
|
$CROSS_TARGET but the script will tell you what the location of the file is
|
||
|
|
if you run it without having the file available.
|
||
|
|
|
||
|
|
For example, if you're using $CROSS_TARGET == "arm-none-linux-gnueabi" then
|
||
|
|
you need to download:
|
||
|
|
|
||
|
|
http://www.codesourcery.com/sgpp/lite/arm/portal/package1787/public/arm-none-linux-gnueabi/arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
|
||
|
|
|
||
|
|
NOTE: simply changing $CROSS_TARGET and modifying the URL accordingly will
|
||
|
|
not work -- you'll need to go to http://www.codesourcery.com and find the
|
||
|
|
correct file, as the release number in the file will also be different (e.g.,
|
||
|
|
in the file above, the release number is "51").
|
||
|
|
|
||
|
|
3. You can override most values in the script without modifying it, e.g.
|
||
|
|
$INSTALL_ROOT (if you want to install in directory other than /usr/local).
|
||
|
|
|
||
|
|
Run the script as:
|
||
|
|
|
||
|
|
% env INSTALL_ROOT=[dir to install in] \
|
||
|
|
CODE_SOURCERY_PKG_PATH=[dir where you downloaded CodeSourcery tarball] \
|
||
|
|
LLVM_PKG_PATH=[dir where you stored your LLVM and LLVM-GCC snapshots] \
|
||
|
|
LLVM_SVN_REV=${REV_L} \
|
||
|
|
LLVMGCC_SVN_REV=${REV_G} \
|
||
|
|
build-install-linux.sh
