I am trying to create a Debian package for LibTorch (C++ API for PyTorch) and encounter linking issues that do not appear with the CMake project.

Steps:

  1. Clone the project

    git clone --recurse-submodule https://github.com/pytorch/pytorch.git -b v2.1.2
cd pytorch

  2. Create a package.xml with content:

    <?xml version="1.0"?>
<?xml-model href="http://download.ros.org/schema/package_format3.xsd" schematypens="http://www.w3.org/2001/XMLSchema"?>
<package format="3">
  <name>libtorch</name>
  <version>2.1.2</version>
  <description>PyTorch C++ API</description>
  <maintainer email="Rauch.Christian@gmx.de">Christian Rauch</maintainer>
  <license>MIT</license>

  <buildtool_depend>cmake</buildtool_depend>

  <build_depend>nvidia-cuda</build_depend>
  <build_depend>python3</build_depend>
  <build_depend>python3-yaml</build_depend>
  <build_depend>python3-setuptools</build_depend>

  <export>
    <build_type>cmake</build_type>
  </export>
</package>

  3. Create Debian package:

    bloom-generate rosdebian --ros-distro humble
fakeroot debian/rules binary

This results in linking errors related to LTO:

[ 97%] Linking CXX shared library ../lib/libtorch_cpu.so

However, running the cmake steps manually does work without these issues.
