MystMan's questions

I am using ubuntu 18.04.3 LTS (Desktop) and tried to install the package PyCBC according to the first line provided at https://pycbc.org/pycbc/latest/html/install.html

That is, I ran:

pip3 install lalsuite pycbc

I found people discussing a similar error here:

https://github.com/sammchardy/python-binance/issues/59

And so I tried upgrading my pip with:

sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get install -y python3-pip

and that actually allowed me to install lalsuite successfully (which was giving me errors before) but not pycbc. The error I get is:

Segmentation fault (core dumped)

with no prior error messages.

Does this happen if you try the same on any ubuntu or am I missing something here? I should note that this is a new ubuntu I just created using VirtualBox so there is nothing else installed.

Do you guys also get the same error when trying:

pip3 install lalsuite pycbc

Could it be because: "at this time, PyCBC supports Python2. Python3 support is under development" (from https://pycbc.org/pycbc/latest/html/install.html)

And just as a quick aside what is the difference between this installation and developing PyCBC given that I just want to use the functions provided?

I am trying to install lalsuite on ubuntu according to the instructions here:

https://pycbc.org/pycbc/latest/html/install_lalsuite.html

Everything went smoothly until I ran

./00boot
./configure --prefix=${VIRTUAL_ENV}/opt/lalsuite --enable-swig-python

And the error I get is:

configure: error: could not find the zlib library

I am doing all this inside a virtual environment using virtualenv. I'm fairly certain I have the zlib library as I installed it with:

$ sudo apt install zlib1g

After a thorough search for a solution I found someone with the same problem:

https://ubuntuforums.org/showthread.php?t=2217198&page=2&s=3d14badd56b8ebb236dfc0970ba19435

But I do not really understand their solution. My interpretation of their fix was to do the following:

First reinstall pkg-config:

sudo apt-get update
sudo apt-get install pkg-config

Then write the line suggested by the answer:

echo 'export PKG_CONFIG=/usr/bin/pkg-config' >> ~/.bashrc

(I am doing all this inside the virtualenv by the way).

Then restart everything and try the same thing again:

./00boot
./configure --prefix=${VIRTUAL_ENV}/opt/lalsuite --enable-swig-python

Sadly the same error appears.

Any help is appreciated.
