I installed some more packages and did what you proposed.
I still get issues with pari / flint and so all related packages.

configure: notice: the following SPKGs did not find equivalent system packages: 
arb brial cddlib cliquer eclib ecm fflas_ffpack flint flintqs fplll gf2x givaro 
gp2c iconv lcalc libatomic_ops libbraiding libsemigroups lrcalc m4rie nauty 
pari pari_elldata pari_galdata pari_galpol pari_nftables pari_seadata 
pari_seadata_small perl_term_readline_gnu planarity r rw symmetrica tachyon
checking for the package system in use... homebrew
configure: hint: installing the following system packages is recommended and 
may avoid building some of the above SPKGs from source:
configure:   $ brew install r

I also have an issue with AM_ICONV, although I have gettext (with path in 
$PATH), readline (recognized) and libiconv.
Checking whether SageMath should install SPKG iconv...
./configure: line 20606: AM_ICONV: command not found
configure: no suitable system package found for SPKG iconv

Don’t know how to fix that. 
I think it’s currently why r is not accepted.

Best,
David.

Re: [sage-devel] error building brial-1.2.5

2020-04-14 Thread Olivier Guillon 
To be more specific, I'm using two different versions of sage on my 
computer, the one brought by arch repos (system-wide, labeled as 
sagemath-9.0-15) and another one build from source from the develop branch 
of sage on github (local, currently SageMath version 9.1 rc0).
I will verify configure options for the latter when I have some time.

[sage-devel] Re: Segmentation fault factoring a multivariate polynomial over IntegerModRing

2020-04-14 Thread Markus Wageringel 
It looks like this problem is going to be fixed by the upgrade to Singular 
4.1.3 (#25993).

sage: R. = Integers(7)[]
sage: p = x**2-1
sage: p.factor()
(x + 1) * (x + 6)

There is another segmentation fault related to the non-commutative 
subsystem Plural, though, causing a doctest failure on the upgrade branch. 
See https://trac.sagemath.org/ticket/25993#comment:22 for details. Any help 
with this is appreciated.

AM_ICONV is a part of gettext

brew install gettext

should fix it.

Re: [sage-devel] error building brial-1.2.5

2020-04-14 Thread Olivier Guillon 
Ok, I just had a 404 error during build because there were no
'.../upstream/sage_brial/' to download from at that time. Your answer
explains why I was able to build eventually after downloading the brial
tarball directly from FTP repository. I'll try to make a separate build
without doing it so as to verify if I can reproduce this behaviour and give
back more useful info. I wasn't aware of the splitting sorry.

upstream_url=https://github.com/BRiAl/BRiAl/releases/download/VERSION/brial-VERSION.tar.bz2

Thus, if you have upstream/brial-1.2.5.tar.bz present and matching md5
etc checksums,
you should be all set.

But if you have brial from the system, you're in trouble as brial is
not built, so upstream/brial-1.2.5.tar.bz
does not get downloaded, sage_brial can't be built, as here is no
tarball on the mirrors at the URL is tries to use.

For some reason, upstream_url= is not helping here, and mirrors shoud
be fixed to have the tarball at the URL in question too.

As a workaround:

in upstream/, do

wget https://github.com/BRiAl/BRiAl/releases/download/1.2.5/brial-1.2.5.tar.bz2

and re-run the build.

HTH
Dima


PS. Volker - is it easy to create these URLs for sage_brial/ to point
to brial/ on the mirrors?

David just posted a message here claiming this not to be the case on
his Arch installation.
Perhaps he has an odd version of Flint conflicting with the system one?
(or just an old installation?)

Apparently in your Arch Flint is not linked with NTL, while this is a
requirement for it to be
in useful in Sage.

E.g. that's on Debian:

dimpase@penguin:~/sage$ ldd /usr/lib/x86_64-linux-gnu/libflint-arb.so
linux-vdso.so.1 (0x7fff6a5fe000)
libflint-2.5.2.so => /usr/lib/libflint-2.5.2.so (0x7d084386d000)
libmpfr.so.6 => /usr/lib/x86_64-linux-gnu/libmpfr.so.6 (0x7d08437eb000)
libgmp.so.10 => /usr/lib/x86_64-linux-gnu/libgmp.so.10 (0x7d0843768000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x7d08435e5000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x7d08435c4000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x7d0843403000)
/lib64/ld-linux-x86-64.so.2 (0x7d0843e39000)
libntl.so.35 => /usr/lib/libntl.so.35 (0x7d0842fd2000)
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x7d0842e4e000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x7d0842e34000)
libgf2x.so.1 => /usr/lib/x86_64-linux-gnu/libgf2x.so.1 (0x7d0842c26000)

So you see libntl there.

Re: [sage-devel] error building brial-1.2.5

2020-04-14 Thread Olivier Guillon 
Ok thanks a lot for the help, everything seems to work for my main source
install as I already said. What I did to solve my issue was essentially the
same as the workaround you just mentioned. There were some interferences
with my system version of brial (brial-1.2.8) it appears.
And, again, congratulations for the great job you're all doing !!!

Hi Antonio,
can Arch's Flint be fixed so that it links against NTL, like in Sage?
Then we won't have to build Flint (and Arb) on Arch...

I far as I understand, your setup is using brial the C++ library from
your system, (and sage_brial, aka Sage interface to brial the C++
library, is built),  so that's not "interference",
it's by design.

[sage-devel] Re: archlinux: some system package not recognized

2020-04-14 Thread David Coudert 
I have similar issues on osx.

I installed several packages using brew. Some of them are recognized, but 
not some others.
I suspect that I'm missing some dependencies, and possibly some environment 
variables.

For instance, I installed amp, mpfr, mpir, ntl and flint, and flint is the 
only one not accepted. Why ?

I have also an issue with readline. I'm unable to tell sage that it has 
been installed with brew :(

Any advise is more than welcome.
Best,
David.

Re: [sage-devel] Re: archlinux: some system package not recognized

2020-04-14 Thread John H Palmieri 
I would suggest two things:

$ brew install pkg-config

and then before building Sage, while in SAGE_ROOT:

$ source .homebrew-build-env

Then try ./configure to see what it says at the end about system packages.
