PEP 517 error when installing with pip

[ayberkydn]

"ERROR: Could not build wheels for pdal which use PEP 517 and cannot be installed directly"

This error message is shown when I try to install PDAL with pip.

The Python and pip versions I tried to install on are;
Python: 3.7 - 3.8
pip: 20.1 - 20.2

I also tried to install virtualenv/conda virtual environments and the system python. Same error message. Not sure if it is a bug or just I am missing something. Tried to google it with no results. Also, pdal 2.1 is installed and working as a command line utility on Arch Linux (installed with pacman).

Here is the full error message:

  ERROR: Failed building wheel for pdal
Failed to build pdal
ERROR: Could not build wheels for pdal which use PEP 517 and cannot be installed directly

[hobu]

As I said in PDAL/PDAL#3201 it looks like the main PDAL library is not installed. Install that first before installing the Python bindings.

[ayberkydn]

I think the main PDAL library is installed, since I am using PDAL in the command line as I mentioned.

>>> pdal --version
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
pdal 2.1.0 (git-version: Release)
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Is there something I am possibly missing?

[hobu]

The Python bindings require the PDAL CMake configuration to be found. I don't know how your PDAL installation in Arch Linux installs that, but the scikit-build stuff in setup.py that uses CMake is not finding it.

What does pdal-config --libs report?

[ayberkydn]

>>> pdal-config --libs
-L/usr/lib -lpdalcpp

[hobu]

How about

ls /usr/lib/cmake/PDAL ?

[ayberkydn]

>>> ls /usr/lib/cmake/PDAL
PDALConfig.cmake  PDALConfigVersion.cmake  PDALTargets.cmake  PDALTargets-noconfig.cmake

[hobu]

you need to tell CMake where PDAL is it seems. Try something like this:

pip install . -- -DPDAL_DIR=/usr/lib/cmake/

[ayberkydn]

Seems it solved the error but now I'm getting another one. I'll try to google it first and inform you about it. Thanks a lot for your time!

[hobu]

Paste it here. The next person who comes along can follow the bread crumbs.

[ayberkydn]

Oh, right.

Your compiler is super new, and it must be more strict about includes. These complaints are due to some assumptions about what is system-included in older compiler setups. I can't offer you much to get past this other than to try an older compiler or try to use clang which might maybe support the older behavior.

We can fix these issues up for a newer release, but that will be a while.

Alternatively, if you're willing to use conda, you can get a conda environment with all of this installed. It is one path to success not blocked by waiting on a patch from us.

I see, I was thinking to fallback to conda but its many-hours-long environment solving times possibly caused by conda-forge repository each time I install a library was setting me back. Thanks a lot!

many-hours-long environment solving time

Make sure to create new environments for every task and this should be greatly reduced. Every install you add to an environment adds to the solve complexity.
