Message-ID: <CANvuJefUY6rmR=BqmfGrp8RCaq-QN0av-ZMC2d5LnRLdZMv-8Q@mail.gmail.com>

Greetings,

I have read and followed the boost.python build documentations thoroughly.
Upon attempting to build the example project
in boost_1_67_0\libs\python\example\tutorial, I'm facing these compile
issues.

Configuration:
boost version: 1.67 and 1.68
build system: boost build and MS Visual Studio 12
python version: 3.6 64-bit

wondering if someone can generously take a look and guide to as to what
could be going wrong?

Hi Boost.Python friends,

I have a library, which consists foremostly of a set of bindings built
using Boost.Python, and I am finding distribution to be a barrier.
Requiring the user to build themselves prevents most of my users from,
well, being users.  Hence, I am writing today to query about best-practices
and ideas on how to distribute my Python library, that consists of pure
Python code installable via pip, a built .so library, and an underlying
.so/.a/.dyld/whatever core library also built from C++.

Thanks for your help,

So you are linking against a 64-bit python build?

But compiling in 32 bit mode?

If so, that could explain the linker errors.I haven't built with bjam/boost
build for a while, but the address-model option can be used to compile 64
bits explicitly.

Hope this helps,
Thomas

the biggest issue really is ABI compatibility, i.e. you can't simply 
distribute a C++ library such as Boost.Python compiled with one 
compiler, and expect it to work in machines with arbitrary other 
compilers (or compiler versions). Once the set of supported compilers / 
compiler versions is settled, it's much easier to share binaries.

If you are mainly working with Python, i.e. if your C++ code is only 
used in extension modules, you may consider using Anaconda, which 
provides some structure in its package management that could help you 
and your users.

Cordially,

Stefan

I get that ABI compatibility is a problem.  That's why I currently require
that my users build from source right now, but it pretty severely limits my
userbase in the community of algebraic geometers, who do *not* want to
compile from source, or navigate dependency hell.

My library is not used only in extension modules; there is a whole general
purpose C++ library my bindings are built against.  So I feel like latching
into Anaconda is a bit scary.  Can you tell me anything more about the
Anaconda ecosystem?  Are there existing Boost.Python binding sets that are
distributed in this model?

I feel like my best options right now are using package managers like
homebrew, apt, etc to help distribute.  Is this possibly the best way?
What are others doing for their Boost.Python generated bindings?  Is there
a list of notable libraries that use Boost.Python, so that I can
investigate directly their distribution models?

Please keep in mind that I am an academic team of ~1, so there's little
buck I can pass on this.  Simple solutions, both to implement and maintain,
are going to be the best.  I really appreciate your time and assistance!!!

Thanks again,
Danielle

Hi Danielle,

I second Stefan?s recommendation, but would like to point out the
distinction between conda the package manager (aka miniconda) and Anaconda
the distribution. Conda the package manager, when used with conda-forge the
community package collection, is the closest thing we have to a good,
lightweight, cross-platform scientific package distribution system we have
at the moment. While conda is written in Python, it is quite good at
describing and resolving the dependencies of arbitrary libraries. When I?ve
had to distribute compiled libraries (or anything else with a nontrivial
dependency tree) for multiple platforms beyond a narrow circle of
collaborators who can be expected to build from source, this has been my
go-to solution.

Platform specific package managers like Homebrew and apt are also an option
(I do quite like Homebrew, for the record), but then you?re stuck
maintaining at least two parallel package systems. With conda you still
have to build separate packages for Linux, OSX, and Windows (or add your
package to conda-forge and have their CI do it for you), but they can share
a recipe.

Cheers,
Jakob

Hello,

I wen't through the tutorial and got stuck at building the quickstart 
example. My setup:

 ??? windows 10
 ??? msvc-14.1
 ??? Anaconda python 2.7

I have setup the user-config.jam file as follows:

 ??? #? Python configuration
 ??? using python
 ??? ??? : 2.7
 ??? ??? : C:\\Users\\Florian_Landolt\\Anaconda3\\envs\\python27_env_1 ;


The main problem seems to be:

/??? extending.cpp(5): fatal error C1083: Datei (Include) kann nicht 
ge?ffnet werden: "boost/python/class.hpp": No such file or directory/

and

/??? embedding.cpp(6): fatal error C1083: Datei (Include) kann nicht 
ge?ffnet werden: "boost/python.hpp": No such file or directory/

I would be very grateful if anyone could help. The console output of the 
build command:

/??? bjam toolset=msvc --verbose-test? --debug-configuration test/

is:
