Compiling with conda fails during installation

[spreiter]

Hi,

many of our machines still run on SL7 and since Python 3.6 reached is end, we want to move to a conda environment.
Besides our necessary packages I created an environment with pugixml and boost installed.
My config:

channel_priority: strict
channels:
    conda-forge
    default

The compilation works, but when I want to install the Python bindings it fails.
Command:

make install prefix=$CONDA_PREFIX

Output:

# Change into rpm/pkg to finally run the customized setup.py
if [ -f setup.cfg ]; then cp setup.cfg /root/ipbus-software/uhal/pycohal/rpm/RPMBUILD/ ; fi
cd /root/ipbus-software/uhal/pycohal/rpm/RPMBUILD && \
  bindir=/usr/local/envs/py38/bin python cactuscore-uhal-pycohal.py install --prefix=/usr/local/envs/py38 --exec-prefix=/usr/local/envs/py38
running install
running bdist_egg

  warnings.warn(

I am not experienced with pip. Anyone an idea how to proper install the Python bindings. Am I maybe missing some argument?
I was following https://ipbus.web.cern.ch/doc/user/html/software/install/compile.html

PS: Using version 2.7.9

@spreiter I'd also be interested in a working conda build, have you figured it out by any chance?

Sadly no. I gave up at some point. For Python 3.6 I compiled it with the system Python binary and its libraries and copied it afterwards into the conda environment. This is definitely not a nice solution, but it worked so far without problems.
