On my develop branch for sage, whenever I attempt to build with ``sage
-br``, I get the following error message:
make: *** No rule to make target `sagelib-no-deps'. Stop.
What could be the cause of this issue? It happened all of the sudden after
I made a new local branch. This is on Sage 9.2.
Thank you, luisfe, for this detailed reply!
Of course it would be formally nice to have the map
lambda x: x.map_coefficients(phi)
be an actual sage homomorphism (which it will always be if phi is a
homomorphism of coefficient rings). But for now what you propose works
fine for me.

Another issue I'm having is that Wordpress will convert empty lines into a
pair. But that seems to be beyond the control of the Cell Server. I
think we need a proper Wordpress plugin to get everything working
flawlessly.

Now you can do:

otherwise I'm out of my depth. You can (should be able to) go back to the

Can you give some more info on what you did? Which commands did you issue?
Which patches did you install? Did you rebuild Sage after installing them?
Which Sage version?
Does your Sage have the "matroids" and "Matroid" keywords on startup?

Hello everyone,
I compiled and installed Sage 5.2 on my homeserver which worked fine and so the
commandline version did.
Then I tried to make sage available fom the Internet with notebook(). I found
some instructions about configuring apache, so access to Sage is carried
through an internal pro

What is the nicest way to create this permutation in one line, other than going
for a Sage dictionary? Also, is there any reason the above constructions don't
work, or are they simply not implemented yet?
Cheers,
Stefan.

Hello group,
I have encountered a somewhat strange problem in plotting a simple
function. It seems to be related to the issues described in the
tutorial section "Some Common Issues with Functions", but the lambda-
function trick does not work here.
I have uploaded a worksheet with what I have bee
broken state
as all subsequent ideal operations (e.g. simple membership tests) will fail
until the worksheet is restarted.

Hi guys,
After searching through the newsgroup for any posts on profiling code
in Sage, I thought I'd make a post asking about what possible methods
are available.

Hey guys,
Is there any way to disable the auto-login feature when a user
accesses the Notebook server from the machine? Since I'm hosting the
notebook server in a VM and have an outside port forwarded to the VM,
any users that access the server globally get logged in as admin.
Thanks!

Ah, I got it figured out. In previous attempts, the host OS was

Hi all,
For the last several days, I've been trying to properly configure port

xpect that factoring
just x is also implemented? Maybe it's also just a bug.
If I replace the definition of the ring R by

then all four examples work correctly.

or IndexError ("list index out of range" for 1). What's wrong?
