Re: C++ and Python package combined

[Nico Schlömer]

Thanks Leo,

If I interpret the build log [1] correctly, again the Python extension is
build and linked with CMake, not `python setup.py install`. Also the
package does some unusual trickery in assembling the setup.py file. Anyhow,
thanks for the pointers.

Cheers,
Nico

there's a python extension cv_bridge

Thanks Leo,

I've checked out ros-bond-core now and found that it's simpler than what I
have: The Python package is installed just like the rest of the library
with CMake, plus there are no compiled Python extensions that would need to
link against the bond library. That's why d/rules can be so simple.
Unfortunately, this doesn't help much with my problem.

Cheers,
Nico

Nico,

maybe it helps. The ROS robotics packages has a lot of examples of C++ libraries
and Python code. They are located in salsa, for instance:

 https://salsa.debian.org/science-team/ros-bond-core

Take one eye. Look any example of package that begins with ros-

Yes, using export in d/rules works as expected.

That sounds like what I got to do. I'm just figuring out which paths I need
exactly. Can I use export in d/rules?

Has something changed to prevent the existing dh overrides from working?

I guess you can set PKG_CONFIG_PATH and others appropriately.
I use these to bring ~/opt/ dirs into various paths:

export 
PKG_CONFIG_PATH=$HOME/opt/lib/pkgconfig:$HOME/opt/share/pkgconfig${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}
export PATH=$HOME/opt/bin:$HOME/opt/games${PATH:+:$PATH}

FEniCS/Dolfin [1]. (I'm preparing the upcoming release.)

> Does the upstream build system not take care of each of the steps?

Like I said, upstream build instructions are:

   1. Build and install the library. (Basically CMake + make install)
   2. `cd python` and install the Python module (basically `python3
setup.py install`)

The latter step relies on the libraries and headers already being installed
on the system.

Nico
