CMake Build Configuration
-------------------------
Transcoder
----------
Before attempting to build Draco with transcoding support you must run an
additional Git command to obtain the submodules:
~~~~~ bash
# Run this command from within your Draco clone.
$ git submodule update --init
# See below if you prefer to use existing versions of Draco dependencies.
~~~~~
In order to build the `draco_transcoder` target, the transcoding support needs
to be explicitly enabled when you run `cmake`, for example:
~~~~~ bash
$ cmake ../ -DDRACO_TRANSCODER_SUPPORTED=ON
~~~~~
The above option is currently not compatible with our Javascript or WebAssembly
builds but all other use cases are supported. Note that binaries and libraries
built with the transcoder support may result in increased binary sizes of the
produced libraries and executables compared to the default CMake settings.
The following CMake variables can be used to configure Draco to use local
copies of third party dependencies instead of git submodules.
- `DRACO_EIGEN_PATH`: this path must contain an Eigen directory that includes
the Eigen sources.
- `DRACO_FILESYSTEM_PATH`: this path must contain the ghc directory where the
filesystem includes are located.
- `DRACO_TINYGLTF_PATH`: this path must contain tiny_gltf.h and its
dependencies.
When not specified the Draco build requires the presence of the submodules that
are stored within `draco/third_party`.
Debugging and Optimization
--------------------------
@ -114,17 +153,52 @@ $ cmake ../ -DDRACO_SANITIZE=address
Googletest Integration
----------------------
Draco includes testing support built using Googletest. To enable Googletest unit
test support the DRACO_TESTS cmake variable must be turned on at cmake
generation time:
Draco includes testing support built using Googletest. The Googletest repository
is included as a submodule of the Draco git repository. Run the following
command to clone the Googletest repository:
~~~~~ bash
$ git submodule update --init
~~~~~
To enable Googletest unit test support the DRACO_TESTS cmake variable must be
turned on at cmake generation time:
~~~~~ bash
$ cmake ../ -DDRACO_TESTS=ON
~~~~~
When cmake is used as shown in the above example the googletest directory must
be a sibling of the Draco repository root directory. To run the tests execute
`draco_tests` from your build output directory.
To run the tests execute `draco_tests` from your build output directory:
~~~~~ bash
$ ./draco_tests
~~~~~
Draco can be configured to use a local Googletest installation. The
`DRACO_GOOGLETEST_PATH` variable overrides the behavior described above and
configures Draco to use the Googletest at the specified path.
Third Party Libraries
---------------------
When Draco is built with transcoding and/or testing support enabled the project
has dependencies on third party libraries:
- [Eigen](https://eigen.tuxfamily.org/)
- Provides various math utilites.
- [Googletest](https://github.com/google/googletest)
- Provides testing support.
- [Gulrak/filesystem](https://github.com/gulrak/filesystem)
- Provides C++17 std::filesystem emulation for pre-C++17 environments.
- [TinyGLTF](https://github.com/syoyo/tinygltf)
- Provides GLTF I/O support.
These dependencies are managed as Git submodules. To obtain the dependencies
run the following command in your Draco repository:
~~~~~ bash
$ git submodule update --init
~~~~~

News
=======
Attention GStatic users: the Draco team strongly recommends using the versioned
URLs for accessing Draco GStatic content. If you are using the URLs that include
the `v1/decoders` substring within the URL, edge caching and GStatic propagation
delays can result in transient errors that can be difficult to diagnose when
new Draco releases are launched. To avoid the issue pin your sites to a
versioned release.
### Version 1.5.6 release:
* Using the versioned www.gstatic.com WASM and Javascript decoders continues
to be recommended. To use v1.5.6, use this URL:
* https://www.gstatic.com/draco/versioned/decoders/1.5.6/*
* The CMake flag DRACO_DEBUG_MSVC_WARNINGS has been replaced with
DRACO_DEBUG_COMPILER_WARNINGS, and the behavior has changed. It is now a
boolean flag defined in draco_options.cmake.
* Bug fixes.
* Security fixes.
### Version 1.5.5 release:
* Using the versioned www.gstatic.com WASM and Javascript decoders continues
to be recommended. To use v1.5.5, use this URL:
* https://www.gstatic.com/draco/versioned/decoders/1.5.5/*
* Bug fix: https://github.com/google/draco/issues/935
### Version 1.5.4 release:
* Using the versioned www.gstatic.com WASM and Javascript decoders continues
to be recommended. To use v1.5.4, use this URL:
* https://www.gstatic.com/draco/versioned/decoders/1.5.4/*
* Added partial support for glTF extensions EXT_mesh_features and
EXT_structural_metadata.
* Bug fixes.
* Security fixes.
### Version 1.5.3 release:
* Using the versioned www.gstatic.com WASM and Javascript decoders continues
to be recommended. To use v1.5.3, use this URL:
* https://www.gstatic.com/draco/versioned/decoders/1.5.3/*
* Bug fixes.
### Version 1.5.2 release
* This is the same as v1.5.1 with the following two bug fixes:
* Fixes DRACO_TRANSCODER_SUPPORTED enabled builds.
* ABI version updated.
### Version 1.5.1 release
* Adds assertion enabled Emscripten builds to the release, and a subset of the
assertion enabled builds to GStatic. See the file listing below.
* Custom paths to third party dependencies are now supported. See BUILDING.md
for more information.
* The CMake configuration file draco-config.cmake is now tested and known to
work for using Draco in Linux, MacOS, and Windows CMake projects. See the
`install_test` subdirectory of `src/draco/tools` for more information.
* Bug fixes.
### Version 1.5.0 release
* Adds the draco_transcoder tool. See the section below on the glTF transcoding
tool, and BUILDING.md for build and dependency information.
* Some changes to configuration variables have been made for this release:
- The DRACO_GLTF flag has been renamed to DRACO_GLTF_BITSTREAM to help
increase understanding of its purpose, which is to limit Draco features to
those included in the Draco glTF specification.
- Variables exported in CMake via draco-config.cmake and find-draco.cmake
(formerly FindDraco.cmake) have been renamed. It's unlikely that this
impacts any existing projects as the aforementioned files were not formed
correctly. See [PR775](https://github.com/google/draco/pull/775) for full
details of the changes.
* A CMake version file has been added.
* The CMake install target now uses absolute paths direct from CMake instead
of building them using CMAKE_INSTALL_PREFIX. This was done to make Draco
easier to use for downstream packagers and should have little to no impact on
users picking up Draco from source.
* Certain MSVC warnings have had their levels changed via compiler flag to
reduce the amount of noise output by the MSVC compilers. Set MSVC warning
level to 4, or define DRACO_DEBUG_MSVC_WARNINGS at CMake configuration time
to restore previous behavior.
* Bug fixes.
### Version 1.4.3 release
* Using the versioned www.gstatic.com WASM and Javascript decoders continues
to be recommended. To use v1.4.3, use this URL:
* https://www.gstatic.com/draco/versioned/decoders/1.4.3/*
* Bug fixes

recommended. To use v1.4.1, use this URL:
