sage not installing from source
I am running Ubuntu 21.04. I have cloned sagemath's source with git and run ./configure folowed by MAKE='make -j4' make. It terminates with errors. The first error is in cysignals-1.10.3. I can't attach the log files here since I do not have enough points. So I hope these are the relevant things from logs/pkgs/cysignals-1.10.3.log:
Processing /home/brett/Projects/SAGE/sage/local/var/tmp/sage/build/cysignals-1.10.3/src
Created temporary directory: /tmp/pip-req-build-reb5uglo
DEPRECATION: A future pip version will change local packages to be built in-place without first copying to a temporary directory. We recommend you use --use-feature=in-tree-build to test your packages with this new behavior before it becomes the default.
pip 21.3 will remove support for this functionality. You can find discussion regarding this at https://github.com/pypa/pip/issues/7555.

One thing I noticed is that it seems to be looking for cython version >= 0.28. ./configure says
cython-0.29.21: standard, will be installed as an SPKG
but python3 -m pip install cython reports that python v0.29 is installed:
Requirement already satisfied: cython in /home/brett/.local/lib/python3.9/site-packages (0.29.24)
Inside log/pkgs/config.log is says
configure:40443: result: cython-0.29.21: standard, will be installed as an SPKG
The file log/pkgs/cython-0.29.21.log reports no errors. Although it does think at the start that cython is not installed:
Package 'cython' is currently not installed
but the python3 pip command above indicates that it is installed on my system.
In the file
logs/pkgs/config.log, there should be a line starting something like "configure:47094: result: cython-0.29.24:" (search for "cython", might be the first hit). What does the rest of that line say? If it says "standard, will be installed as an SPKG", then what does the cython log file say?I have added that information
Sage should build its own pip and its own cython — that's expected. I don't know what's going wrong here, though.
Thanks for letting me know that building its own pip and cython is normal. Is there something I can do to get better information on the error? Do you know what information the process is trying to get from address 192.0.2.0? Are there other venues for getting help with compiling sagemath?
