Installation instructions for Alembic

0) Before Alembic can be built, you will need to satisfy its external
dependencies.  They are, as of July, 2012:

A unix-like OS (Linux, Mac OS X); Windows support is experimental
CMake (2.8.0) www.cmake.org
Boost (1.44) www.boost.org
ilmbase (1.0.3) www.openexr.com
HDF5 (1.8.9) www.hdfgroup.org/HDF5
zlib

Optional:
pyilmbase (1.0.0) # to build the python bindings
Arnold (3.0)
Autodesk Maya (2012)
Pixar PRMan (15.x)
OpenEXR (1.7.1) www.openexr.com
Sphinx (1.1.3) # to build the python documentation

Note that the versions given parenthetically above are minimum-tested
versions.  You may have good luck with later or earlier versions, but this is
what we've been building Alembic against.

They may be installed in their default system locations (typically somewhere
under /usr/local), or some other centralized directory at
your discretion; it's best not to install your dependencies under the Alembic
source root. If you do install under a centralized directory you can specify
this root in the bootstrap using --dependency-install-root; this will make the
process of searching for depedencies go smoothly.

Look in your Alembic source root's "doc" directory for
instructions on building Boost and HDF5; see next step for details.

Note: for building the Alembic Python bindings (aka PyAlembic), only Boost versions
1.44 through 1.48 are known to work. For more information see this OpenEXR
support ticket on github:

AcademySoftwareFoundation/openexr#41

1) Untar the Alembic source into your desired directory:

$ cd ~/ ; tar xzf ALEMBIC_SOURCE_-xxxxxxxx.tgz

This will create a directory, ~/ALEMBIC_SOURCE, that contains the Alembic
source code (if you're reading this, you've probably already done this).

As alluded to in Step 0, ~/ALEMBIC_SOURCE/doc/ will contain instructional
files for building Boost and HDF5.  Mostly, those packages' libraries just
need a little encouragement to build static archives and with -fPIC.

2) The Alembic build bootstrap script assumes
an out-of-source build.  For purposes of illustration, this document assumes
that your build root is located parallel to your source root, though that is
not required.

3) Run the Alembic bootstrap script. The following should work:

$ python ~/ALEMBIC_SOURCE/build/bootstrap/alembic_bootstrap.py [build_dir]

You can give it several options and flags; '-h' for a list of them.  If you
don't specify a complete set of options when you run it, it will prompt you
interactively for the information it needs to initialize the build system.

It's worth pointing out that running the bootstrap script is optional; there
is a fairly comprehensive set of CMake files there that might just work for
you "out of the box".  On the other hand, we do strongly recommend running
the bootstrapper; it will make things so much easier for you.

4) Once the system is bootstrapped, there will be a file called "CMakeCache.txt"
in your build root.  You can examine and manipulate this file with the cmake
commands "ccmake" (curses-based console program), or "cmake-gui" (Qt-based
gui program).  This file is the control file for CMake itself; the main thing
the bootstrapper does is create it and populate it appropriately (the bootstrap
script will also use it to get default values for the things it asks you for).

You can also just edit it directly, if you know what you're doing.  If you
change it, just be sure to run "cmake ." in the same directory as it so that
it regenerates the Makefiles.

5) Run the make command.  Kind of a no-brainer, really.  You can safely run make
with the '-j' flag, for doing multi-process builds.  In general, you can
profitably run as many "make" processes as you have CPUs, so for a dual-proc
machine,

$ make -j2

will build it as quickly as possible.  Once the Alembic project has been built,
you can optionally run:

$ make test

or,

$ make install

each of which does what you'd expect.  Running

$ make help

will give you a list of possible targets.  If you want to make a debug build,
you can either run the bootstrap script again with the option '--debug', or
run ccmake or cmake-gui (depending on what you installed when you installed
cmake, as described in 4a), and change the build type to "Debug".

6) To build the API documentation via Doxygen:

$ cd ../ALEMBIC_SOURCE; doxygen Doxyfile

This will generate html documentation in the doc/html folder.

Alembic AbcCoreHDF5 Changes 

Purpose of code changes on this branch:


When reviewing my code changes, please focus on:
WriteSampleID improvements done here:
http://code.google.com/r/millerlucas-dev/source/detail?r=3d72463d0e36f5841c272f6
31d30ae0af6917dff

The rest of the changes should be relatively uncontroversial as they are some 
low risk HDF5 usage cleanups.

After the review, someone will merge this branch into:
/default
/point9

Attachments:

Build binaries for windows for 1.0 - also make windows HDF5 calls multithread safe 

Just a general issue being tracked here to collect all the steps required to 
get this building on Windows.

To start, you need:

1) a 64-bit compiler, preferably one that was used to build Maya (VC++ 9.0?)

2) The following Boost libraries, static and multi-threaded, 64-bit:
   - libboost_program_options
   - libboost_thread

3) hdf5.lib and hdf5_hl.lib (static, thread-safe, C-only, 64-bit)

4) 64-bit zlib (need this for HDF5)

5) 64-bit ilmbase libs, statically linked.

6) CMake 2.8

Once these things are done, we can start trying to build Alembic itself :)

Build fails 

I just cloned the head revision, got all the dependencies setup, tried to build 
and it fails:

error: no matching function for call to

Is this a known issue, or is it a problem with my setup?

Build system does not refresh stale value for cmake variable "ALEMBIC_BOOST_FOUND" 

What steps will reproduce the problem?
1. Follow instructions to build Alembic via bootstrap method
    python ../build/bootstrap/alembic_bootstrap.py
2. During bootstrap set paths accordingly

What is the expected output? What do you see instead?
Expected to successfully bootstrap the build process

Instead the following error appears:
CMake Error at CMakeLists.txt:187 (MESSAGE):
  Boost version 1.42.0 found.  Require 1.42.0.  Check your BOOST_ROOT
  environment variable.

What version of the product are you using? On what operating system?
Alembic 0.9.0 on Centos 5.3 x86_64

Please provide any additional information below.
It would appear that in CMakeLists.txt the boost check cannot pass unless 
ALEMBIC_BOOST_FOUND is true. If BOOST_FOUND is true, regardless of what version 
of Boost is found, it will error.

Alembic does not work on 32-bit architectures 

In Util/Dimensions.h the following assert
    BOOST_STATIC_ASSERT( sizeof( MySizeT ) == sizeof( T ) );
prevents us from compiling Alembic on 32 bit architectures. This may only be 
the beginning of the difficulties.

Add Richard and Rob's correct titles to the signature line for their message about the .9 release 

Right now, on the alembic.io page, and on the front page of the Google Code 
site, there's not indication as to who Rob and Richard are.

Also, on the alembic.io page, it looks like the message was truncated, as 
there's no indication that the line that says "Richard Kerris and Rob Bredow" 
is supposed to be a signature.

Add support for rank-N TypedArrayProperties 

Basically, we just need to add the following methods:

OTypedArrayProperty::setRank()
OTypedArrayProperty::getRank()
ITypedArrayProperty::getRank()

See Util/Dimensions.h and 
http://code.google.com/p/alembic/source/browse/lib/Alembic/Util/Tests/Dimensions
TestJeffs.cpp for examples of manipulating this.

Then, in the OTypedArrayProperty::set() method, we just need to set up the for 
loops to properly interleave the data, and do the right thing in 
ITypedArrayProperty::get() to read it correctly.

I *think*.  This may require a bit of smartness/changes in 
Abc::TypedArraySample as well.

Can't write uniform samples starting at any time other than zero 

This works:
   mass.set( mm,  OSampleSelector(tt) );  // write sample # tt at time 0 + dt*tt
This dies:
  mass.set( mm,  OSampleSelector(tt, 400.0 + tt*dt ) );
with:
terminate called after throwing an instance of 'Alembic::Util::Exception'
  what():  Invalid rank in timeSamples attr read
