How to remove Profiling *.gcda:Cannot open errors with python virtualenv builder?

Question

In jenkins output I am getting the following errors. Is this a problem or can it be silenced?

I built python from source on the debian 8 server.

Answer 1

I fixed this issue by doing change owner. I was setting up homeassistant using Python 3.6.3 build using ./configure --enable-optimizations. From my virtual env i got these errors but fixed them doing: from su / root account

sudo chown -R homeassistant:homeassistant /home/pi/Python-3.6.3

I thought maybe it could help other people ;) Have a nice day! Ciao!

Answer 2

This happened to me when I did ./configure --enable-optimizations. If you remove --enable-optimizations, compile and install it again - these messages are not shown anymore.

To sum things up, here's an example with a fresh version of Python:

wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz
tar xvf Python-3.6.3.tgz
cd Python-3.6.3
./configure
make
sudo make altinstall
python3.6
