Yes I decided not to go my usual way of adding bin to PATH. The symbolic link is actually very convenient and I will use it a lot more from now on. And thanks for enlightening me on sage and the installation process.

It never recovered. Not sure what happened but at the 6 hour mark, I decided to stop it by force.

@John Palmieri I managed to get it working. I had to run make ptest and all tests passed successfully, something must have been wrong with make ptest long. Now I can start using sage for math. I want to add sage to my PATH so I can run it from anywhere. Initially I wanted to add $HOME/sage/inst/bin to my PATH but this directory contains executables and symbolic links for a lot of programs such as python 2 and python 3. Would doing this cause conflicts with my system installed python? If so then is adding the SAGE_ROOT directory i.e. $HOME/sage/src/sage a better option?

I ran make -j5 ptestlong and the compilation has been stuck on this screen for over 1 hour:

[dochtml] [thematic_] dumping object inventory... done
[dochtml] [thematic_] build succeeded.
[dochtml] [thematic_] The HTML pages are in ../inst/share/doc/sage/html/en/thematic_tutorials.
[dochtml] Build finished. The built documents can be found in /home/user/sagemath/inst/share/doc/sage/html/en/thematic_tutorials
[dochtml] Elapsed time: 1729.2 seconds.
[dochtml] Done building the documentation!

Everything on the screen is static except for the blinking cursor at the end after the last line.

I know the process is still running because ps -ef | grep -i make shows that the process has been running for nearly 6 hours now.

• Has the build frozen or is this what i should expect from running make -j5 ptestlong?

Yes that's how I should have done it. make -j5 ptestlong has been running for nearly 5 hours now. Its been stuck on the part below for almost an hour now:

[dochtml] [thematic_] dumping object inventory... done
[dochtml] [thematic_] build succeeded.
[dochtml] [thematic_] The HTML pages are in ../inst/share/doc/sage/html/en/thematic_tutorials.
[dochtml] Build finished. The built documents can be found in /home/user/sagemath/inst/share/doc/sage/html/en/thematic_tutorials
[dochtml] Elapsed time: 1729.2 seconds.
[dochtml] Done building the documentation!

There is no prompt but the cursor is still blinking. My system still sounds like its on full throttle and ps -ef | grep -i make shows that this process is still running. Is this normal or is something wrong?

Well, make -j5 ptestlong didn't work, it caused an error unless I ran make distclean first and now make -j5 ptestlong is saying I don't have a maths library.

Edit: Your method would have worked (The clue why it didn't work is below.)

checking whether make -j5 ptestlong sets $(MAKE)... no
checking whether make -j5 ptestlong supports nested variables... no

I was setting the environment variable export MAKE="make -j5 ptestlong" thinking that by running make it would execute this command. I was wrong because the message above shows that it doesn't set make. This works only when the ptestlong command is excluded which raises the suspicion that MAKE takes only one command. The way to do it is to run the command make -j5 ptestlong directly in the command line.

I don't have logs in that path

@Iguananaut Files:cat /proc/cpuinfo, and ppl-1.2.p1 config.log. Hope that's useful.

To add to my first bullet point, shouldn't you run make distclean before running make again or make -j5 ptestlong especially when a build fails?

@John Palmieri gcc (GCC) 8.1.1 20180502 (Red Hat 8.1.1-1). I read on the github page that python test suite is already disabled, quote:

"Python's test suite has been disabled by default, because it causes failures on most systems. To renable the Python testsuite, set the environment variable SAGE_CHECK_PACKAGES to "python"

• What do I have to do before running make again?
• And should i run make ptestlong before running make -j5 or after it?
• PPL is for numerical optimisation, is it not a bad idea to skip tests for it?
• What's the difference between make ptest and make ptestlong? Doesn't the latter test external dependencies like maple etc

I set export SAGE_CHECK="yes" to run tests on the spkgs before running make -j5. This gives me another build breaking error, despite using python 2 to build sage
