Hmm, interesting. That's a new one to me. (Aside: the "python2" vs "python3" warning text is a side-effect of error reporting; this is not a python version problem.) The Is there any chance that your machine is running out of RAM? If so, try creating a file named |

Given that Drake has continuous integration builds that test this exact configuration (Ubuntu 20.04, GCC 9.3), there must be something else present in your environment that differs from our default builds. I'm going to need more information to try to reproduce your problem. What revision (git commit hash) of Drake are you using)? What is the exact command line you are running to perform the build?

So below is the feedback that I have : What revision (git commit hash) of Drake are you using)? What is the exact command line you are running to perform the build? What is the output of env (a dump of all of your environment variables)? What does which gcc report? What does file /usr/bin/gcc report? |

Here's a patch to print which library we're trying to use: --- a/tools/workspace/pybind11/pybind_coverage_libclang_parser.py

Can you add that and see what it prints? When operating correctly, I see this output: After that, here's how to check for any stray library dependencies: When operating correctly, I see this output: In both cases, I'm wondering if you might have software installed into Another option would be to try the Drake build in a clean terminal (one that doesn't have any ROS or FOAM variables set). Those settings are all supposed to be nixed and ignored automatically by Bazel during the build, but it's possible something is leaking through. On another note, while I am curious to figure out why the build is broken (and fix it in Drake proper), I'll also note that For example, if you only need pydrake you can |

We should suppress that at this stage. I will open an issue. I nuked it in Russ's repo's somehow. |
Ive been trying to compile using Bazel build however I keep getting the below error is there anyway around it?
Note: The failure of target //tools/workspace/pybind11:generate_pybind_coverage (with exit code 1) may have been caused by the fact that it is running under Python 3 instead of Python 2. Examine the error to determine if that appears to be the problem. Since this target is built in the host configuration, the only way to change its version is to set --host_force_python=PY2, which affects the entire build.
