We now have changes ready for building the viewer with the new Linden
Lab "autobuild" tool (not to be confused with any other similarly named
tool written by anyone else). Autobuild is a framework for maintaining
and building libraries and other programs. It acts as director providing
a common interface to build and package libraries and programs, but it
is not a build system like make or cmake (it uses them "under the covers").
The autobuild framework has now been applied to the viewer build as a
whole, so that we'll soon have a common command-line method to build on
all platforms.
Once these changes are merged, you'll be able to build with just two
commands starting from a clean checkout: one to configure (which only
need be done once in each working copy), and one to actually do the build.
To configure your clean working copy:
A default Linden developer build:
autobuild configure -c RelWithDebInfo
A default non-Linden developer build:
autobuild configure -c OpenSourceRelWithDebInfo
A "standalone" non-Linden developer build:
autobuild configure -c OpenSourceStandaloneRelWithDebInfo
Needless to say, there are ways to provide more detailed and
fine-grained controls, and there are other possible targets for the
-c (--configuration) option.
The actual build command is:
autobuild build-c OpenSourceRelWithDebInfo
Most of the components that the viewer depends on have either been
converted to building with autobuild, or are in the process of being
converted. The open source dependencies will eventually all be in
bitbucket.org/lindenlab (aka hg.secondlife.com) repositories; many are
already there, and you build each of them in exactly the same way.
To begin experimenting with this new way of doing things, you'll need to
check out autobuild itself (it's written in python, and is open source)
from:
https://bitbucket.org/lindenlab/autobuild
You can either run it directly from the checkout, or install it as a
normal python package using the command:
setup.py install
There are some pages on the wiki that describe how to use autobuild;
like all wiki content, improvements are welcome.
The viewer repository modified to use autobuild is at:
https://bitbucket.org/mani_linden/viewer-autobuild
How soon this is merged into viewer-development depends in large part on
the feedback we get from this email, but our hope is that it will be
very soon. When it is merged, this will be the only "supported" way to
build the viewer - which is to say that:
1. Doing it any other idiosyncratic way is up to you and
contributions to support them are ok as long as they don't break
the supported method.
2. All contributions must build cleanly using the supported method.
If you are on windows, you must ensure that the Visual Studio executable
(devenv.com) is in the path that the shell you run autobuild in is
using. You can set the path using the 'vsvars32.bat' file, found in
the directory referenced by the variable VSxxCOMNTOOLS, where 'xx'
depends on the version of VS that you're using (the "supported" value is
still '80', but upgrading that is coming real soon now....).
So... download and try these out. Feedback to the list rather than jira
issues until we merge this into viewer-development, please.
