I have installed free-threading python 3.13 following https://py-free-threading.github.io/installing_cpython/ on ubuntu 22.04(with gcc 11.04.0), with command:

conda create -n nogil --override-channels -c conda-forge python-freethreading

But compile python 3.13t with boost-1.86.0 failed, below the steps:

1, configure boost successfully:
./bootstrap.sh --with-python=/home/mydesktop/anaconda3/envs/nogil

2, compile boost failed:
./b2 --toolset=gcc --with-python include="/home/mydesktop/anaconda3/envs/nogil/include/python3.13t/" --with-thread --with-date_time --with-chrono --with-system
3, error message:

Obviously I missed "pyconfig.h", but i successfully compiled boost 1.86 with python 3.11 with the same step. Any suggestions? Thanks in advance!

@grafikrobot , do you know what's wrong here ? My b2 knowledge is next to non-existent.

@stefanseefeld hmm.. something strange is going on with the include paths for python:

-I"/home/subaochen/anaconda3/envs/nogil/include/python3.13"
-I"/home/subaochen/anaconda3/envs/nogil/include/python3.1t"

It would help if we got the output of running the build with the --debug-configuration option.

I can reproduce this build error if I leave out the include="/path/to/include/python3.13t/" part, if I add it things do work. Full reproducer:

$ git clone [email protected]:boostorg/boost.git
$ git submodule update --init --recursive
$ cd boost

$ conda create -n boostpython python-freethreading  compilers
$ conda activate boostpython

$ ./b2 --toolset=gcc --with-python --with-thread --with-date_time --with-chrono --with-system

Change the build command to add an explicit include path:

$ ./b2 --toolset=gcc --with-python include=/home/rgommers/mambaforge/envs/boostpython/include/python3.13t --with-thread --with-date_time --with-chrono --with-system
...
The Boost C++ Libraries were successfully built!

The generated project-config.jam file does set the path to the root dir for the Python executable, but no related include path:

# B2 Configuration
# Automatically generated by bootstrap.sh

import option ;
import feature ;

# Compiler configuration. This definition will be used unless
# you already have defined some toolsets in your user-config.jam
# file.
if ! gcc in [ feature.values <toolset> ]
{
    using gcc ; 
}

project : default-build <toolset>gcc ;

# Python configuration
import python ;
if ! [ python.configured ]
{
    using python : 3.13 : "/home/rgommers/mambaforge/envs/boostpython" ;
}

path-constant ICU_PATH : /usr ;


# List of --with-<library> and --without-<library>
# options. If left empty, all libraries will be built.
# Options specified on the command line completely
# override this variable.
libraries =  ;

# These settings are equivalent to corresponding command-line
# options.
option.set prefix : /usr/local ;
option.set exec-prefix : /usr/local ;
option.set libdir : /usr/local/lib ;
option.set includedir : /usr/local/include ;

# Stop on first error
option.set keep-going : false ;

Knowing where that include path is set would be helpful I guess (I'm not familiar with b2 either) - or is it expected that one has to manually add it if the python executable isn't the system one?

It would help if we got the output of running the build with the --debug-configuration option.

compilation terminated.

I checked that my CMake is recent enough; it's at 3.31.6 while 3.30.0 is the minimum version needed for free-threaded CPython support (such versions are tracked here, I'll add Boost.Python to that table as well).

In the end this looks like all it needs is appending a single t to the include path that the build system calculates based on the Python minor version.

Okay, found it I think:

https://github.com/bfgroup/b2/blob/f518c83dbbcce621df81ab29e7b2a33498a35ca2/src/tools/python.jam#L563

version is still 3.13 for a free-threaded interpreter, so what is needed is to detect that a free-threaded interpreter is being run and if so, append t. The solution will be similar to mesonbuild/meson#13338 I think: run the interpreter, and check for this sysconfig variable:

>>> import sysconfig
>>> sysconfig.get_config_var('Py_GIL_DISABLED')
