error building sage-9.3 from source

[Greg Marks]

On a Debian 10 system, building sage-9.3 from source fails with this
error:

I've tried it both with "./configure --with-system-flint=no" and with
"./configure --with-system-arb=no" and with a simple "./configure";
same problem each way.

Best regards,

For the record, this problem was solved by starting the build with
"./configure --with-system-python3=no"; then "make" completes without
error and "make ptestlong" shows all sage-9.3 tests passed.

P.S. On some machines with Python 3.7.3 installed, the problem described
above arises; on others it doesn't. I suspect the problem has something
to do with the specific Python packages installed and is possibly
related to the (currently unanswered) question posed here:

We'd need to see the top-level config.log corresponding to a failing build.

Hi Greg,

Could you check what `libflint-arb.so*` files and `libarb.so*` files are on your system? I suspect that an old libarb is being picked up somehow.

This symbol has been present in arb since 2.12. Debian stretch has 2.8 so if somehow a libarb.so from the system gets picked up there it would explain it.

I don't think it's related btw.
