Hi,
Today I installed sage on Ubuntu 22.04 using
apt install sagemath
Sadly after typing 'sage' the program crashes. The crash seems to be
related to Cython. I am attaching the crash report.
What are my options?
Best regards,

The root locus plot of a complex function is basically the zero locus

Thanks for the reply. But no. The problem is not due to the fact that
the function has a singularity. Indeed.

I never have any luck with plotting in Sage. The simplest plots fail.
For example the following
plot(20*log(abs((1+I*x)^4+4),10),(x,0,3))
fails with
TypeError: float() argument must be a string or a number
I don't see what's wrong with it.

Ok it seems that li(x)=Ei(log(x)) and this works for complex values.
Furthermore Li(x)=li(x)-li(2).
It seems that Li(x) has been artificially curtailed to take

Hi,

to illustrate
Riemann prime number formula but now it seems Li(z) accept only real

In a different shell I get the error message again.
I think sometimes sage picks up the system wide libgcc_s.so.1 instead
of its own copy.
Any help in resolving this would be appreciated. My system is FC4.

Hmm, these instructions seem to be directed heavily towards Ubuntu.
I am (still...) a Fedora user. But the good news is that making
a chroot jail on Fedora seems to be relatively easy using
yum (the Fedora equivalent of apt-get). I'll see how
far I get and report back.

No patch but I can tell you were there is something obviously wrong.
The matrix H on line 1056 in matrix_integer_dense.pyx should
be the empty matrix (perhaps []?) but it is something like ['',''].
The computation
for adding the missing zero rows goes wrong after that.

I think I now understand the problem. A while ago
I pulled over a compiled version of sage-2.0 from a

Anyway I have downloaded and compiled 2.1.0.1 now.

this moment there is an unpleasant inconsistency between some
functions and others.
E.g. log(2) or sqrt(2) evaluate immediately, whereas sin(2) doesn't.
