- If you download databases using windows, only download the .gz files! Otherwise the file will be corrupted.
A central directory of ARB databases available on the web can be found at
ARB database central.
We encourage you to share your work with others and to publish a link to your own database there.

- Don't ask - there IS no version for Windows
Linux-Requirements: A recent version of Linux (based on libc 6).
To detect which version you have type 'ldd /bin/su'. If libc.so.6 shows up you have a version based on libc 6.
ARB can be quite hungry for memory, depending on the database.
Please have a look at the ARB hardware requirements.
First, go through the readme:
Then choose version to install from this page.
Click on the respective link and download the following files:
|arb_install.sh||: Installation script|
|arb-*.tgz||: ARB program (choose one of the provided versions, not all!)|
Once you have downloaded these files,
put them into a directory,
open a console window in that directory and
run the "arb_install.sh" script there.
Answer the queries to install the "ARB program".
- Do not uncompress and untar arb.tgz directly, instead, use the install script (arb_install.sh)!
ARB versions in this section are maintained by ARB users
Initial port by Ben Hines and Mike Dyall-Smith.
Mike also maintains the
ARB for Mac OS X
Since 2008 ongoing mac ports by Matt Cottrell. We included Matts build instructions into the ARB tarball (and online at arb_OS_X_MacPorts.txt and arb_OS_X.txt).
UNTESTED and/or EXPERIMENTAL version of ARB is available as Debian package and the same can be downloaded here.
Debian version is maintained by Andreas Tille.
You may as well try one of the latest development builds - but please notice that
These versions are untested builds from our developers and may be completely broken!
Do not use without backing up your databases.
You may download the
latest development builds
from the arb-silva ftp server.
Builds there are sorted by year and build number and you'll find two general kinds of development builds:
build-XXX using motif (like release does)
gtk-build-XXX using gtk (still not fully supporting everything)
Both versions approx. provide the same functionality.
Please access the source using our
or if you just wanna look, simply browse the source.
You´ll also find a tarball (arbsrc.tgz) in every build.

- If you make changes to the source code and think the public should benefit from them, please send a diff against the latest SVN version (instructions howto do this can be found here).
