Error while building 'UsdGeomMesh’ has no member named ‘CreatePrimvar’

[joshuacv]

Following the sdf instructions here (http://sdformat.org/tutorials?tut=install), I tried to build the sdf2usd convertor and failed and then found the readme in the sdformat github and through that found this github page.

Environment

• OS Version: Ubuntu 20.04
• Source build: Main branch and looks like commit number is 6fb572b5ed3c4cf165de158b193a33cace6ef2b5

Description

• Expected behavior: Successful build and install
• Actual behavior: During build, the following error was encountered: gz-usd/src/sdf_parser/Geometry.cc:376:34: error: ‘class pxrInternal_v0_22pxrReserved::UsdGeomMesh’ has no member named ‘CreatePrimvar’ 376 | auto coordinates = usdMesh.CreatePrimvar(

Steps to reproduce

• USD: installation instructions
• gz-usd
• sdformat Build gz-usd. The steps below follow a traditional cmake build, but gz-usd git clone https://github.com/gazebosim/gz-usd

  cd gz-usd
  mkdir build
  cd build
  cmake ..

  Output

/gz-usd/src/sdf_parser/Geometry.cc:376:34: error: ‘class pxrInternal_v0_22pxrReserved::UsdGeomMesh’ has no member named ‘CreatePrimvar’ 376 | auto coordinates = usdMesh.CreatePrimvar( | ^~~~~ make[2]: [src/CMakeFiles/ignition-usd0.dir/build.make:102: src/CMakeFiles/ignition-usd0.dir/sdf_parser/Geometry.cc.o] Error 1 make[1]: [CMakeFiles/Makefile2:1456: src/CMakeFiles/ignition-usd0.dir/all] Error 2 make: *** [Makefile:163: all] Error 2

Other details

• sdfformat version is sdfformat12 (was built from source)
• usd release branch (1c2b097a48edd78abeffb0e7b4c8adfec4d14060) - built from source

Found out that this is because USD support is only for a particular branch. You have to clone the correct branch and build it otherwise gz-usd wont build. This is NOT documented. I will make a pull request in gz-usd.

• USD: Note: USD support is only available when building sdformat from source. USD requires CMAKE 3.12 this package is available from Ubuntu 20.0.

  Clone the USD repository

  git clone --depth 1 -b v21.11 https://github.com/PixarAnimationStudios/USD.git

  Note: Only v21.11 is supported currently

  Install dependencies not managed by the build script

  sudo apt install libpyside2-dev python3-opengl cmake libglu1-mesa-dev freeglut3-dev mesa-common-dev

  Use the build script to compile USD. In order to speed up compilation, it is recommended to disable unneeded components.

  cd USD
  python3 build_scripts/build_usd.py --build-variant release --no-tests --no-examples --no-tutorials --no-docs --no-python <install_dir>

  For more information regarding the build options, see the USD docs at https://github.com/PixarAnimationStudios/USD/tree/v21.11#getting-and-building-the-code.

  Add USD to system paths (replace with the path to your USD install directory)

  export PATH=<install_dir>/bin:$PATH
  export LD_LIBRARY_PATH=<install_dir>/lib:$LD_LIBRARY_PATH
  export CMAKE_PREFIX_PATH=<install_dir>:$CMAKE_PREFIX_PATH
