Pybind11 Crashes on Makefile installation

Asked by Sean Boerner

I am installing Pybind11. I have run the following lines:

git clone https://github.com/pybind/pybind11.git
cd pybind11/
mkdir build
cd build/
cmake ..
make install

The installation terminates with:

:
:

make: *** [Makefile:130: all] Error 2

It appears that the compilation of the test_stl.cpp file requires an include directory of ./boost/libs/optional/include/, which it doesn't have.

How do I resolve this so that the installation completes without a problem?

TIA

1. Ubuntu provides a pre-compiled version of pybind11 in its repositories.
sudo apt install python3-pybind11
and if needed
sudo apt install pybind11-doc

2. If you try to install a foreign version of software, then this is outside ubuntu support.

Based on the error message that you receive, I assume that you are missing a software package that is required for building that foreign pybind11 package. In your case probably it's libboost(version)-dev, e.g. for jammy libboost1.74-dev, for focal libboost1.71-dev

I had tried:

sudo apt-get install python-pybind11

and got the following:

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package python-pybind11

I used your suggestion:

sudo apt install python3-pybind11

and that worked.

Thank you
