I too have developed a C++/C Ant/Ivy cross-platform (x86, and assorted arm)
development environment.
Like Maurer, we created ant scripts that all of a common interface of
build/test/install/publish targets.. For projects that we control, we use that
interface to drive CMake.. Since all our projects use CMake, I was able to
create 'helper ant files' to handle most of the heavy lifting, so that a
build.xml file for a project is 4 lines long. Third party stuff is somewhat
chaotic, since everything wants to build differently, but we try to maintain
that ant interface as best we can.
One thing that needs to be considered is what files get stored in Ivy.. I
didn't want the maintenance overhead of keeping track of all the header files
that are added, so in our 'install', we always install to a particular
directory (<project>/installed_files). Then in the publish, I zip up that
entire directory, and that is my artifact. I have a trigger on the download of
a dependency to unzip the files. (into <project>/dependencies). This allows us
to write the CMake build scripts to always look into ./dependencies for the
needed files.
Since we need to be cross platform, I added a "platform" in the dependency info:
<dependency name="libManager" rev="trunk" e:platform="${platform}" />
That platform gets injected into my repo path:
<sftp name="shared" user="..." userPassword="..." host="..."
checksums="sha1,md5" checkmodified="true" changingPattern="*">
<ivy
pattern="ivy_shared_repo/[organisation]/[module]/[platform]/ivys/[revision]/ivy.xml"/>
<artifact
pattern="ivy_shared_repo/[organisation]/[module]/[platform]/[type]s/[revision]/[artifact].[ext]"/>
</sftp>
</resolvers>
When we build or publish, we pass what platform it is: ant -Dplatform=arm-debug
Now we can have pre-compiled dependencies, for multiple platforms.
Its worked fairly well, though some complain that to switch between platforms
is somewhat of a pain (have to clear out the build, and rebuild everything, or
use a separate directory).. But thats far better than the previous system we
had (none).. Now if I can get all the groups to get rid of their svn:externals
(being used for pretty much the same thing, trying to assemble multiple
projects into a single one), my life would be much easier.

We've been extensively using Ant/ivy in our C++ environment.
The main reason was actually ivy to have a (transitive) dependency manager, but
also to have the same "build/install/run/test" interface to all our projects.
The idea is pretty simple: We have a company-wide repository of common
libraries (C++source and pre-compiled) in different versions that can be used
in other projects.
When building a project, the correct (in term of version) dependee modules are
downloaded from the repository, extracted and locally build (with the normal
build environment e.g. MSVC, make). We also implemented an auto-environment
feature that creates suitable environment variables pointing to the include /
import library paths of the locally built common modules.
But be warned: We had to extensively use Python scripts to enhance Ant/Ivy to
make it all work and it cost many man-months. In the end, we use ant as a
standardized interface to our build management system, use ivy for dependency
management and leave the rest to python scripts.
But once set up, it works *really* good.

Betreff: Ivy in C/C++ environment
I wonder if somebody has some pointers for using Ivy in a C/C++ environment.
a) how is dependency management done (e.g. using custom resolver?)
b) how is building done (based on on de Ivy dependencies)
I'm not looking for a complete solution, just wat to start a discussion about
possibilities or perhaps best practices from people already having this set up.
Unfortunately I can't find and information in the docs. Ivy is especially
interesting as it is nog tight to Java dependency management.
