System: PCLinuxOS 32bit Mate

gcc: 4.92

pkgconfig: 0.28

python2: 2.7.6

python3: 3.4.2

I want add log from compile, but I don't know how.

How I can find pyconfig.h ?

[tele]

# find /usr -name pyconfig.h /usr/include/python3.4m/pyconfig.h /usr/include/multiarch-i386-linux/python3.4m/pyconfig.h /usr/include/multiarch-i386-linux/python2.7/pyconfig.h /usr/include/python2.7/pyconfig.h

[tele]

# find /usr -name pyconfig.h
/usr/include/python3.4m/pyconfig.h
/usr/include/multiarch-i386-linux/python3.4m/pyconfig.h
/usr/include/multiarch-i386-linux/python2.7/pyconfig.h
/usr/include/python2.7/pyconfig.h

[tele]

Interesting is g++ option from log

-I"/usr/include/python3.4"

and my path

/usr/include/python3.4m/

[Jürgen Hunold]

Most probably Boost.Build fails to parse the include path reported by your python binary. Can you please run "b2 --debug-configuration" and attach the log?

[anonymous]

When I copy files from /usr/include/python3.4m/ to /usr/include/python3.4/

...updated 68 targets...


The Boost C++ Libraries were successfully built!

The following directory should be added to compiler include paths:

    /home/gg/Downloads/DOWNLOAD/test/boost_1_57_0

The following directory should be added to linker library paths:

    /home/gg/Downloads/DOWNLOAD/test/boost_1_57_0/stage/lib

I added also "b2 --debug-configuration" now above :)

[tele]

I will try ask on PCLinuxOS forum. I would like add symlinks files from .../python3.4m/ to .../python3.4/ but I don't know if this is good way.

[Jürgen Hunold]

The error might also be in bootstrap.sh. Can you add "project-config.jam" too?

[tele]

This is the same bug
​https://svn.boost.org/trac/boost/ticket/6826

[tele]

I checked path /usr/include/python3.4m/

• Mageia , Fedora , OpenSuse have similar path for pyconfig.h in python3

I tried compile on OpenSuse , I have the same problem with this path.

[Steven Watanabe]

The offending code in python.jam is

        includes ?= $(prefix)/include/python$(version) ;

A better workaround is to edit project-config.jam to pass the correct include path explicitly.

using python : 3.4 : /usr : /usr/include/python3.4m ;

[tele]

Thanks :)
So I will try edit /boost_1_57_0/tools/build/src/tools/python.jam to add "m"

 includes ?= $(prefix)/include/python$(version)m ;

[Steven Watanabe]

A general fix would be more like:

[ path.glob $(prefix)/include : python$(version)* ]

[tele]

I don't know python however:

        if  not($(prefix)/include/python$(version)m)
        {   
           debug-message "Used include path: $(prefix)/include/python$(version)m" ;
           includes ?= $(prefix)/include/python$(version)m ;
        }
        else
        {
           debug-message "Used include path: $(prefix)/include/python$(version)" ;
           includes ?= $(prefix)/include/python$(version) ;
        }

        local lib = $(exec-prefix)/lib ;
        libraries ?= $(lib)/python$(version)/config $(lib) ;

I tried add before " path.glob $(prefix)/include : python$(version)* " but python libs missed ( libboost_python ) and I con not find error.

Anyone will update python support ?
I ask because I see ./bootstrap.sh can add only 1 python version to project-config.jam

[tele]

You tried add something with if ?

if [ path.glob $(prefix)/include : python$(version)* ]
...

[tele]

blee , above what I paste working wrong , if any can fix I will happy.

[anonymous]

I tried also something

        for local file_name in  glob.glob("{prefix}/include/python{version}*/Python.h".format(version=$(version), prefix=$(prefix)))
#  file_name = /usr/include/python3.4m/Python.h

        includes ?= $(file_name)[:-9] ;
#       includes ?= /usr/include/python3.4m ;
          {
          debug-message "Python$(version) path: $(file_name) ;
          }

And also this is wrong and I don't know what is wrong inside this. This is python jam , yes ? Exist IDE for python jam ? How can create fast script and test in python jam ?

[marcus.hanwell@…]

This still appears to be an issue in Boost 1.59.0, I found this report when searching for my problem. I guess not all installs symlink the directory without the m. It would be great to resolve as it can take quite a while to get here.

[anonymous]

Reporting that this bug is still present. On OSX with python3 installed via brew.

Bootstrap with

./bootstrap.sh --with-python=python3

Here's how to fix this manually for now:

In the file tools/build/v2/tools/python.jam, line 542, change

includes ?= $(prefix)/include/python$(version) ;

to

includes ?= $(prefix)/include/python$(version)m ;

(as proposed by steven_watanabe)

Hoping that a real fix will come for version 1.60.

[j.r.versteegh@…]

Still present in 1.60.

python-config should be used to determine the python include path.

[j.r.versteegh@…]

Modification of python.jam to use abiflags

[j.r.versteegh@…]

python.jam appears to get values from "import sys", so the above patch attempts to get the abiflags from there as well. Tested with python2.7 and python3.4 on linux mint amd64.

[anonymous]

Same error exists on OSX due to the difference in folder names. When installing Python3 with brew (brew install python3) Python is installed in this folder: /usr/local/Cellar/python3/3.6.2/Frameworks/Python.framework/Versions/3.6

Boost configuration detects the folder correctly but sets the include path as: /usr/local/Cellar/python3/3.6.2/Frameworks/Python.framework/Versions/3.6/include/python3.6

While brew installation places include files in: /usr/local/Cellar/python3/3.6.2/Frameworks/Python.framework/Versions/3.6/include/python3.6m

This can be solved by soft linking folder include/python3.6 to include/python3.6m but it's not obvious, and boost library build does not work out of the box.

[anonymous]

Are there any plans to fix this bug?

[liam.gretton@…]

I just hit this bug in 1.64.0 too, here's another vote for a fix please.

[anonymous]

Please fix this already.

[ofloveandhate]

october 2017, and i'm beyond eager to have a fix.

[ofloveandhate]

maybe this will be fixed after boost moves to cmake for its build system?

[Microsamp]

I am waiting for a fix too. Python2.7 on Mint amd64 with 1_16_0/1_65_1(both tested today)

[anonymous]

Please fix this

[orangesherbet0@…]

pyconfig.h still not found in boost 1.66, building boost on Linux Mint (roughly equal to Ubuntu 16.04).

[anonymous]

Facing the same problem Centos 7 boost 1.65

[anonymous]

can i do anything here? if i make it use python-config, is there a chance you will merge? this really makes it hard to automate this...

[anonymous]

apt-get install python-dev
