Hello,

I am trying to install astrometry.net on my system running ubuntu 20.04. I have read the installations from http://astrometry.net/doc/build.html#build. Before installing I have tried to install the libraries as is mentioned in the website. I have attached the results of installing the libraries. Now when I am doing make, it is giving some error. I have attached the log of the same.

I would like to get some help with the installation. I do not want to use the online version, and want to write scripts in python.

--Thanks and regards,

Anirban

Well I googled up a bit and found a solution to the problem. In my case

sudo apt-get install python3-dev and python3-numpy seems to solve the problem. Make is now running and installation is successful. Thanks a lot

Ubuntu 20.04 already comes with a recent version (0.78) of
astrometry.net, so you don't need to compile it yourself:

$ sudo apt install astrometry.net

Best regards

Thanks a lot. I didn't know about a apt-get version of astrometry.net. But I solved the problem by installing astropy and running solve-field in a python3 environment.
