Re: python-pyarrow broken for parquet?

[phil]

Thanks Simon.

Yep I got this far too - and I have a candidate fix for building parquet.  But 
it's tremendously hacky (sed'ing hardcoded variables into the cmake files to 
trample the derived settings in several places).  It seems to work but needs 
finessing.  I'll post here shortly, but not sure it's stable enough to be 
updated in Guix proper.  We can debate that when everyone sees my horrendous 
fix.

The package 'apache-arrow' is built with the Parquet support but not
the package 'python-pyarrow'.  To add the support of Parquet to the
Python binding, the environment variable PYTHON_WITH_PARQUET should be
set to 1, IIRC the doc.

Tweaking the 'python-pyarrow' with:

--8<---------------cut here---------------start------------->8---
      (add-after 'unpack 'set-env
        (lambda _ (setenv "PYARROW_WITH_PARQUET" "1") #t)))))
--8<---------------cut here---------------end--------------->8---

then running "./pre-inst-env guix build python-pyarrow --no-grafts" I get:

--8<---------------cut here---------------start------------->8---

Without this environment variable PYTHON_WITH_PYARROW set to 1, the
configuration is not looking after Parquet, for instance:

Well, setting the environment variable is not enough.  :-)  Do you
want to give a try for fixing it?


All the best,
