Hi Andy, thanks for the quick reply. I only came across pybind recently when I was encountering some dependency issues with boost.python and looked for an alternative. It looks really useful, but I hesitated to make the switch - but I think I will do it sooner or later. Maybe one question regarding pybind - is it easy to create bindings for different Python versions? Am 29.04.20, 16:42 schrieb Andrew Voelkel <jandyman.voel...@gmail.com>:
Have you considered using pybind11? It’s the same basic idea as boost.python, but it is cleaner, much better supported and documented, and has a large user community. I just discovered this lately, have been using it, and I’m thrilled with it. The only catch is that you need to be compiling with at least a C++11 compiler, but that is a pretty low bar these days.

Subject: [C++-sig] Compiling boost python
I'm trying to compile boost.python with a version of python, that I've downloaded and built myself.
Is the "No-install quickstart"-page (https://www.boost.org/doc/libs/1_73_0/libs/python/doc/html/building/no_install_quickstart.html) still updated, because some of the links are broken and
I honestly don't understand what is going on there.
Some questions that I have:
- What is the bjam "build driver"? When I go to Section 5 of the boost Getting Started page - they mention something about an easy install option and another one for custom binaries.
The entire page mentions neither bjam, nor "build driver".
- I manage to build boost, by first running the bootstrap script and then calling b2 - if I select e.g. graph - it is built and copied into the correct directory, that I've specified. However,
it doesn't work with my own Python folder.
I wrote a small script to automate all steps:
#wget https://dl.bintray.com/boostorg/release/1.73.0/source/boost_1_73_0.tar.gz
#tar -xvf boost_1_73_0.tar.gz
cd boost_1_73_0
./bootstrap.sh --prefix=../build_boost --with-libraries=python -with-python-root=../Python-3.6.10 --with-python-version=3.6
./b2 install -d+2
echo "using python : : ../Python-3.6.10/python ;" > user-config.jam
My folder structure is as follows:
buildBoost.sh (the script above)
/Python-3.6.10 (contains the python source code and binaries that I've build myself)
/boost_1_73_0 (boost source code as downloaded by the script)
/build_boost (output folder as specified by prefix)
When do I need to write this user-config.jam file? What are the compilation scripts looking for - can this process be debugged?
I also have boost installed via apt - now I think that everytime I call b2 or bjam it uses
the global versions of these programs, instead of the ones contained in the boost-directory I'm compiling - is that an issue?
