Your comment #37 seems to be the best choice. Since I
use Fedora I have needed 3.0 for quite a while. But,
right now I am working on other stuff, so it is not
an urgent requirement.

In any case, thanks for all your help.

I plan to keep compatibility with both and will try to extend it also to the coming Sundials 4.0 but will only have time to work on this on December.

I'm really going to use what I proposed in (4) for the reasons I explained there.

Question on this: do you want to preserve compatibility with both SUNDIALS 2.7 and 3.x, or just switch to 3.x?

sorry I misspelled a sentence in the previous comment :

"With the patch modified by Orion the SUNDIALS is completely skipped so SUNDIALS becomes a mandatory dependency."

should read

"With the patch modified by Orion the variables set by configure to signal whetehr SUNDIALS is usable are completely ignored so SUNDIALS becomes a mandatory dependency."

to make things more clear I personally I think over-linking would be a minor issue (but I don't know what JWE would think about it).

The real issue is that the pre-processor fags used in conditionals inside _ode15_.cc should be set by configure by testing that a working SUNDIALS is available, not removed and ignored.

I'm not saying you should assign flags to make the build complete on your system.

What I say is that the configure script should be somehow able to detect whether or not a SUNDIALS installation is present on your system and whether or not it has the correct features, then decide whether or not Octave should link or not to SUNDIALS.

With the patch modified by Orion the SUNDIALS is completely skipped so SUNDIALS becomes a mandatory dependency.

From what I gather from configure.ac, indeed, octave does (1).

In my system, qhull doesn't have a .pc file, fftw does (what makes things easier).

The only penalty on giving assignments to *FLAGS to ./configure in step/phase, this is what I'm doing, is related to overlinking and it affects the binaries mostly if we are using static libs, with dynamic libs the unused references would be eliminated with --as-needed option on linking phase (it is not a clear cut, though, e.g., https://wiki.mageia.org/en/Overlinking_issues_in_packaging).

Have (4) implemented is doable to deal with complex cases but I would have to clear the dust from my previous knowledge about autotools. I can do it, but it will take time and I'm in a very busy period right now.

Andre da Costa Barros <andrecbarros>

removing conditionals in the source code means
that building Octave will just outright fail when sundials
is not available or not the correct version.

As sundials is an optional dependency that should not be the case.

If you know some autotools scripting and would like to
propose a solution according to item 4 in your comment #30
that would be indeed welcome, but just removing all
conditionals and forcing the link is not an acceptable option.

To see how other optional dependencies are treated you may
look for example at what is done for FFTW, GLPK or QHULL.

"are not on cached/standard" -> "are not inside cached/standard"
"in may case" -> "in my case"

Sorry for that.

Andre da Costa Barros <andrecbarros>
Sun 04 Nov 2018 07:51:05 PM UTC, comment #30:

Hum, by parts:

1 - I don't know how octave handle it, but on many packages when you set *FLAGS it means a start point, not a whole substitution (more or less equivalent to SOMEFLAGS="$SOMEFLAGS --what-you-set-explicitly";
2 - It would be easier if every package generated a pkg-config .pc file to query where things are located and how to "link" and "include" things. Many don't, sundials doesn't;
3 - octave could get out of its way to guess where things were located using ldd and ldconfig on linux but things get really complicated when we use libraries that are not on cached/standard dirs;
4 - A possible solutions for this would be if octave had an option to, say, "some-random-lib" in the form of --with-some-random-lib-libs="-L<some_dir> -ldep1 -ldep2 .. -ldepn" in addtition to what it already use (--with-some-random-lib=, --with-some-random-lib-libdir= and --some-random-lib-includedir=);

Of course, the patch can and should be improved but, in may case, octave would, possibly, have to address (3) and (4) as I link sundials to superlu_mt and hypre and the standard setting may fail to get the extra linkage (i.e., the configure.in would have to check for extra libraries dependencies; not worth in my opinion as LDFLAGS and CFLAGS are simple and straightforward).

What I described in (4) would be a nice addition, I think (some packages use this).

Orion, Andre,

If I understand correctly what you are doing in file #45334
is remove all Preprocessor conditionals in order to force
using the code for sundials, is that the case?

The whole point in the patch is to detect
automatically the flags to set in order to
link with SUNDIALS so, if you need to set
the flags manually that means the patch is
not working.

As I said in comment #25 this part of the
patch was probably not correct even for SUDIALS 2.

Additionally, I had to add to LDFLAGS "-lsundials_ida -lsundials_idas -lsundials_sunlinsolklu -lsundials_fsunlinsolklu" but it is working now with sundials 3.2.1.

Thanks to everyone involved!

I've attached my updated version of the patch. I also needed to set CPPFLAGS=-I/usr/include/suitesparse in order for the sundials headers to find klu.h.

thanks for uploading the configuration files.
From what I see:

1) I found an error in the configure tests that I will fix ASAP
2) I am surprised this worked ever before even for sundials2

Yes, the changeset is relative to the default branch.
Yes, you need to run bootstrat to get a new configure script when configure.ac is patched.

I was messing with this stuff so I would need to recreate them.
Could you verify that
a) patach to be applied on default (dev) branch, not on stable.
b) since it patches configure.ac I need to re-run bootstrap
prior to configure.

Thanks for testing.

Indeed there seems to be something wrong, either
SUNLINSOL_KLU is installed but is not detected
or it is not installed, in which case its header
should not be included.

Which one is the case for you? Does "locate sunlinsol_klu.h"
return something for you?

here is an updated patch, this works for me on macos 10.13 with a self built sudials 3.1.0

can someone else test the patch and/or look at it (especially the configure tests)?

I built _ode15_.oct using this version of mingw:

c:\temp\Projects\ode15_ming64>where g++
c:\Program Files\mingw-w64\x86_64-7.2.0-win32-seh-rt_v5-rev1\mingw64\bin\g++.exe

Then, I ran these tests:

>> which ode15s

'ode15s' is a function from the file C:\Octave\OCTAVE~3.0\share\octave\4.4.0\m\ode\ode15s.m

>> test ode15s

PASSES 39 out of 39 tests

>> test ode15i

PASSES 48 out of 48 tests

I could do more testing, if needed.

I turned your patch into a proper changeset that applies on the current development branch and made a few style fixes.

How did you build and test the code?

If I apply the changeset and run "configure" the tests for IDADENSE and IDAKLU fail and ode15{i,s} get disabled ...

I think I patched revision 25054 of _ode15_.cc.

I can see that these patch files are rather problematic with
respect to the version of the file they are created for.
So, as you suggested, I just uploaded the full, modified _ode15_.cc. This version has been built and tested with octave 4.4.0.

Bill, Thanks for your patch and sorry for the late reply.

The patch does seem to have been greated correctly
but it does not apply to the current development branch,
what exact version of Octave did you start with for creating the patch?

If you don't feel like going through the trouble of creating
a well formed mercurial changeset you can just download the latest version of ode15.cc from the hgweb interface using the following link:


and upload the full modified file.

Tue 03 Apr 2018 12:59:03 AM UTC, comment #4:

I added more tests to configure on the stable branch as a stopgap for this bug for the Octave 4.4 release


This will automatically disable building against SUNDIALS 3.0.0 and later. Octave 4.4 will build against version 2.7.0 only. This is no longer a build failure error, so recategorizing and retitling.

Please do comment if there are still build errors that the new configure changes don't take care of automatically.

Leaving this bug open until after the release when someone has time to fix it on the development branch by rewriting the interface to the new IDA API.

I've built a copy of sundials 3.1.0 and I confirm the error and that the API has changed significantly.

I think we're probably short on time to get a true fix in for 4.4, so it might make sense to add tests to configure for the ida_dense API and conditionally compile out those parts of the code. I can take a look at doing that in the short term.

It would be really nice if someone familiar with the SUNDIALS interface could take a look at this for Octave 4.4, since distributions will probably start moving to SUNDIALS 3 very soon.

As initially reported in [1]: Sundials has changed the treatment of dense matrices [1], such that "ida_dense.h" which is included by "__ode15__.cc" is gone.

From the manual:

> Added generic SUNMATRIX module with three provided implementations:
> dense, banded and sparse.
> These replicate previous SUNDIALS Dls and Sls matrix structures in a
> single object-oriented API.
