That's great. Some of these aren't yet at the list of FreeBSD

Ah, yes, this is a little hard. See
http://www.sagemath.org/doc/developer/patching_spkgs.html, though that
is more detail than you need. Really, you just need to untar the
.spkg file, make your change, then tar it back up. I think that the
specific commands are at
http://www.sagemath.org/doc/developer/producing_spkgs.html#creating-a-new-spkg.

Probably something in Python didn't get built that should. Seeing
more of the details would help.

GAP at least is known, apparently - see

You need this to pass/use certain stuff in plotting. See
http://trac.sagemath.org/sage_trac/ticket/7345.
For now, our goal would just be to successfully *build* Sage.

I think the best strategy for immediately is for you to get a Trac
account so that you can put your experiences with each (failing)
package there for others to be able to help. See
http://trac.sagemath.org/sage_trac/ and follow the instructions at the
top. Then you can either post your failure messages to appropriate
tickets, or open a new one (for instance for the pycrypto).
Thanks! Please let us know if you have any other questions. I
encourage you to continue this conversation at sage-devel, where I am
cross-posting this response.

main problem that seems to be holding me up is when I try to build the
sage4.8 subpackage. I get an error that says that sem_opn is not
functioning. However I am using a version of FreeBSD that has
semaphores installed by default.
I am guessing that the problem might be in the build of python, which
might incorrectly autodetect that sem_opn is not functioning.
Can anyone give me guidance on how to approach this problem?
Thanks, Stephen
Stephen Montgomery-Smith
Hey, I figured it out. I hope to get a working sage on FreeBSD soon.
Stephen Montgomery-Smith
contains a "port" to build sage on FreeBSD. (FreeBSD users will know
what I mean by a "port.")
It does seem to work, but it segfaults on exit:

Any ideas on how to proceed?

I did a "sage -gdb" and it suggests that the problem might be to do with
~Commentator in commentator.C. This is part of the linbox subpackage.
I did a google and found this:
http://trac.sagemath.org/sage_trac/ticket/11718
Does construction and/or deconstruction of Commentator tend to cause
problems?
Paulo César Pereira de Andrade
I do not remember all details about this, but hopefully this can help

Stephen Montgomery-Smith
I tried this, and it didn't seem to work in my situation.
Stephen Montgomery-Smith
I fixed the problem as follows:
sed -i .bak -e 's/Commentator/Commensator/g' \
"$SAGE_ROOT"/local/lib/liblinboxsage.so.0
That way sage didn't get confused between the Commentator that appears
in liblinbox and liblinboxsage.
Now I am getting a different segmentation fault, for which unfortunately
gdb provides no clues.

Can you still post what output/debugging info you have?

Stephen Montgomery-Smith
I am in the process of compiling with the "-g" option set. I'll send
you the output when this is done.
Stephen Montgomery-Smith
The "-g" option didn't seem to help one bit. This is what I got.
Not all of the subpackages respect CFLAGS or CXXFLAGS. But I don't know
if that is the reason the symbols are not showing up.
Any advice?

That little bit makes me suspect an issue similar to:

FreeBSD has a working python version 2.7. How do I tell the sage build
to use the FreeBSD python rather than building its own?
François Bissey
sage-on-gentoo that does just that).
Seriously using system python with the stock sage tarball is just asking
for a lot of pain (including serious patching).
I don't think your problem is with python strictly speaking, if it turns out
to be pynac, that's quite different, although discussion is that something
in the sage code can be done to mitigate the issue.

The major problem is "bootstraping", and possibly "political" issues if you
need patches in other packages you do not maintain. Once you get it
working, usually updating to a newer sagemath is reasonably simple,
just don't let it rot for too long.
François know I did not look in my sage package for almost too months :-)
While I had some known doctest failures for very long due to using a
different version of some component, e.g. python, for several times I
found bugs that just did not trigger in sage due to it not using packages
outside its install tree.

It was related to linbox. My "fix" using sed wasn't working.
What I did was to rebuild linbox. I removed any reference to
-DDISABLE_COMMENTATOR (which I did by hacking commentator.h so that
-DDISABLE_COMMENTATOR had no effect). Then I found I had to remove the
patch to commentator.C that is in patches, so that "Commentator
commentator" is no longer commented out.
Then it worked. sage doesn't crash on exit!!!
I think there is a real problem with linbox and linboxsage both
containing different versions of the same function (namely
~Commentator). I have had prior experience with this, and this sort of
thing seems to bite FreeBSD when other OS's don't get bit at all.

What kind of pain?
Were does the serious patching apply? In python itself or in dependent
packages?

So it built successfully. I ran "sage -testall" and it did fail a few
of them ("ccosh" not found seemed like a common error).
Is this normal, or should I post test.log and have it analyzed?
Also, I made a few minor corrections to the port, and I will post that
later today.

This might be solvable by installing cephes on FreeBSD. This is
included in Sage but only installed on Cygwin.

juggling with PYTHONPATH or put things in a standard system location.
Sage itself need a little bit of care in setup.py so you can find and install
everything. Of course the current python shipped with sage also has a small
but annoying patch that has only been merged recently and will be in
python-2.7.3, some small functionality won't work without it.

Hmmm... my systems seem to have a python 2.7.2+ installed, so I should
probably wait before I experiment about it ;-)

On my system, complex cosh is the cosh function, overloaded to accept
complex arguments. I don't have complex.h for C++ - rather I would use
#include <cmath>
#include <complex>
I had a similar problem with sage-main/sage/symbolic/pynac_cc.h, which
was looking for functions like logl. I had to change logl to log
overloaded to work with long double (just like this file does for
__CYGWIN__).
This is a definitely C++ construction, not C.
My system does have complex.h (which I think is the C99 version of C).
The only non-trivial functions it has is csqrt.
(I found this out by grepping the include directories.)
Stephen Montgomery-Smith
According to "spkg/installed", my system seems to have installed cephes.
These failures are happening in
sage -t -force_lib "devel/sage/sage/calculus/riemann.pyx"

But on my Linux system, complex.h has a link to bits/cmathcalls.h, and
that does have ccosh. And ccosh is part of libm.
So I will have to figure out if I can make this work with FreeBSD.

But now that I look in cephes-2.8/spkg-install I see what you mean. I
will try building cephes.

OK, now I understand what you were trying to tell me.
So I modified it so that cephes now builds. It seems to help a little,
because in the log file for r-2.14.0.p1.log it says that it found ccosh,
when previously it said it didn't.
Nevertheless, I am still getting the same errors when I run
> sage -t -force_lib "devel/sage/sage/calculus/riemann.pyx"
I see in the source code that there are huge numbers of places where
CYGWIN is checked. So it is really hard for me to trace whether there
is a check somewhere else for CYGWIN that causes it to try cephes first
before looking in /usr/local/include.
Thanks, Stephen

it says that "make -j4" is respected. This works really great when
building the source code.
But the documentation also suggests that it should be building in
parallel when creating the documentation? Should there by 4 invocations
of python working at once? Or is one python supposed to be running 4
threads?

This came up somewhere else recently, and this ticket was mentioned:
http://trac.sagemath.org/sage_trac/ticket/6495
If I remember correctly, the docs all build serially at the moment.

As far as cephes is concerned, if you need it, you should be able to
change
#!/usr/bin/env bash
if [ "$UNAME" != "CYGWIN" ]; then
echo "We do not install the cephes library on any operating system
except Cygwin."
exit 0
fi
appropriately. But checks for Cygwin shouldn't impact other systems,
including FreeBSD.

I just found this.

It caused build errors in other sub-packages. But I have spent too many
late nights on figuring out the FreeBSD build, and I am going to have to
take a rest for a while.

Yes, I should have given you proper attribution, as the emails you sent
me a few months ago were how I found these tickets.

find some time I'll try to take your notes and put comments on the
appropriate tickets.

things can be very annoying to look up. I just wanted to make sure
you weren't doing the VERY tedious process of searching Trac by hand.
Trac's search function is so slow that it's faster to use Google
search on it.

http://trac.sagemath.org/sage_trac/ticket/12400
http://trac.sagemath.org/sage_trac/ticket/12401
are followup tickets with some of the stuff from the "port" attached
or copied.
Stephen Montgomery-Smith
I am still working on this port. Not all the changes I suggested will
necessarily remain.
Just to add some info:
http://trac.sagemath.org/sage_trac/ticket/12400 - this was copied from
the python26 port for FreeBSD.
http://trac.sagemath.org/sage_trac/ticket/12401 - this patch also needs
to be applied to devel/sage-main/sage/symbolic/pynac_cc.h. This patch
is rather crude in that I didn't surround the changes with ".if
defined(__FreeBSD__)". However we are not supposed to use __FreeBSD__
but the rather more complex construction described at
http://www.freebsd.org/doc/en/books/porters-handbook/porting-versions.html.
Also, if I get cephes to work under FreeBSD,
http://trac.sagemath.org/sage_trac/ticket/12401 may end up as an
unnecessary patch.
The patch I proposed to singular-3-1-3-3.p3 should be made into a
ticket. It removes a test in a configure file that serves no purpose as
far as I can see.
The FreeBSD build of sage is going to require some hacks so that it uses
the version of cc that comes with the ports, not the base cc. I have
already incorporated this in the latest version of the FreeBSD port,
which I just committed to the FreeBSD project.
I suspect that anyone who wants to install sage on FreeBSD will always
have to do it via ports.
Finally, I am doing a bit more as time allows, but I am very busy with
teaching at the moment. When the summer arrives, I hope to have a lot
more time.

I fixed the problem as follows:
sed -i .bak -e 's/Commentator/Commensator/g' \
That's not a fix. The POSIX definition of 'sed' does not include a -i option, so this will not be portable. I'm 99.9 % sure it would break on Solaris

with the sed shipped with AIX for example. This is downright painful but it is
indeed not portable.

It didn't work anyway.
