arpack's openmpi variant conflicts with gcc45

[mkae (Marko Käning)]

How to recover from this:

The following installed ports are outdated:

This was introduced in r107140, which was done to fix #39365

[mamoll (Mark Moll)]

This can be fixed like so:

sudo port -f uninstall arpack
sudo port install arpack +openmpi -gcc45

Let me know if that works.

[mkae (Marko Käning)]

Now that I tried to install arpack from source I can't even download the sources:

:debug:fetch Fetching distfile failed:: The requested URL returned error: 404
:notice:fetch --->  Attempting to fetch arpack-ng-3.1.3.tar.gz from http://forge.scilab.org/index.php/p/arpack-ng/downloads/get

Will try in the evening again, perhaps it is only a temporary issue.

I can see this is a little confusing, but you need to install openmpi with one the gccXX variants. So try this:

sudo port deactivate opempi
sudo port install openmpi +gcc47
sudo port install arpack +openmpi -gcc45 -gcc47

[mkae (Marko Käning)]

When I follow the instructions I get

Can you do this:

sudo port clean arpack
sudo port install arpack +openmpi -gcc45 -gcc47

And copy/paste the output of configure if it still fails?

This is hard to understand. Can you post config.log (/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_math_arpack/arpack/work/arpack-ng-3.1.3/config.log)? Also, if you do port installed openmpi what does it show?

[mkae (Marko Käning)]

$ port installed openmpi
The following ports are currently installed:
  openmpi @1.7.1_0+gcc47 (active)

[dstrubbe (David Strubbe)]

This is interference from another OpenMPI installation:

configure:16364: checking for mpif77
configure:16380: found /usr/bin/mpif77
configure:16391: result: mpif77
configure:16409: checking for MPI_Init
configure:16416: mpif77 -o conftest -O2 -m64 /usr/lib/libblas.dylib /usr/lib/liblapack.dylib conftest.f  >&5
--------------------------------------------------------------------------
Unfortunately, this installation of Open MPI was not compiled with
Fortran 77 support.  As such, the mpif77 compiler is non-functional.

--------------------------------------------------------------------------

Apparently we have to set MPIF77 explicitly to avoid this. I had thought setting F77 would be enough, but apparently not. Attached patch accomplishes this.

[vertreko@…]

Hi. I'm having this problem too. I found the Portfile for arpack, patched it, did a 'sudo port clean arpack' followed by 'sudo port install arpack'. I got the errors in vertreko_01_main.log while building the port.

This is a totally different issue. You are using OSX 10.6, apparently, and I guess Accelerate in that version just doesn't have one of the needed symbols. What do you get if you do "nm /usr/lib/libblas.dylib | grep lsame" ? Also, I am guessing you have atlas installed, right?

  atlas @3.10.1_2+gcc46

[dstrubbe (David Strubbe)]

Well, you do have the symbol. Try this modification:

-    configure.args-append  LDFLAGS='/usr/lib/libblas.dylib /usr/lib/liblapack.dylib' --with-blas="-lblas -llapack"
+    configure.args-append  LDFLAGS='/usr/lib/liblapack.dylib /usr/lib/libblas.dylib' --with-blas="-llapack -lblas"

At any rate, if you are just looking to get some version of arpack installed, probably using +atlas instead will work for you.

[vertreko@…]

Yeah, given your question re: atlas I started 'sudo port install arpack -accelerate +atlas'. Unfortunately, after it scanned for linker errors it decided it needed to rebuild atlas, and in order to do that, it needed to compile and install gcc46, which it's been working on for the last half hour - LOL! I've gone down the rabbit hole, and have the uncomfortable feeling that it will end with me deleting /opt ...

Fears unfounded. After gcc46 was built things went pretty smoothly. Octave seems to be working with the new arpack+atlas.

[dstrubbe (David Strubbe)]

Ok, glad to hear that succeeded. Would you mind trying out +accelerate also with the reordered configure.args-append above too, to check whether that fix works?

Is there a way to build a port variant if you don't want to subsequently tag it as the "active" one? I'm happy to try to build arpack with the change but I don't want to mess up my installation.

Use port destroot instead of port install, to perform all stages except the install and activate phases. You’ll have to manually run port clean afterwards, of course.

[vertreko@…]

Same error. Diffing the two main.log files shows the different flag ordering, but the linker still died without finding _lsame_. Log diff attached.

Hm, what about going back to the style we had for 3.1.2?

[mamoll (Mark Moll)]

Fine with me. I don't remember why this was changed.

[dstrubbe (David Strubbe)]

Sorry, let me be clearer about who my comments are addressed to.

mk: doesn't the patch I attached solve your problem about openmpif77? If not, can you specify what problem you still experience?

vertreko: Would the +accelerate build work if you deactivate atlas? Are you building univeral? Would it work if you subsituted for the configure.args-append line:

configure.args-append --with-blas="/usr/lib/libblas.dylib" --with-lapack="/usr/lib/liblapack.dylib"

mmoll: The version I mention that we had for 3.1.2 doesn't work anymore for 3.1.3 due to apparent bugs in ld and/or libtool. I changed it as a workaround. But it may be that the workaround is not successful on MacOS 10.6.

That all looks fine, and successful to me (since the right one was 'accepted'). That is just checking the various conditions, I don't think those are errors or warnings. If the MPI_Init part failed in configure again, please look for the relevant part in config.log (i.e. what I put up above), or attach the whole thing.

I'm still not seeing any errors. MPI_Init for openmpif77 was accepted, so the patch solved that problem. Down at the bottom it says: configure: exit 0 So, looks like the configure stage was successful.

Configure works by trying all kinds of things and seeing which work and which don't. It's only an error if it says it is. Anyway, just look at your main.log to see where (if anywhere) an error occurred.

[mkae (Marko Käning)]

The error I am seeing is in comment:6.

[dstrubbe (David Strubbe)]

Replying to mk@…:

The error I am seeing is in comment:6.

I'm sorry, that's not possible unless there is a horrible bug in macports. Your config.log says configure exit status was 0. You state that the corresponding main.log has configure exit status was 1. Also, the content you say is in your main.log, a summary of the configure command, is not found in config.log. Please look very carefully at your files. Perhaps your build succeeded and you are looking at the wrong log file.

Sure, I can believe that is what happened you when tried to install, but the config.log you supplied must not be from that build attempt. Can you also do port clean --all arpack just to be sure? If you really have a failure to compile an MPI test program, I think the most likely reason is you are somehow still using the unpatched Portfile.

[mkae (Marko Käning)]

I did the clean.

And, as I realize now, you were absolutely right! -> I DID screw up on my end!!! :-(

After increasing the revision in my local port file MacPorts indeed used the local portfile which wasn't the case during all my other tries. :-| My god, I was sure it would be doing it. But I totally forgot was, that this specific MP installation hadn't enabled my local SVN tree in /opt/local/etc/macports/sources.conf.

I'll upload the main.log which still throws an error, but at least a different one.

SORRY, and thanks for your patience with me.

I see now that I am at comment:17.

So I guess I should try building with gcc46, just like in comment:20...

[mkae (Marko Käning)]

So, now that I have openmpi installed in its gcc46 variant arpack won't want to install anymore because of that:

What am I missing?

[mamoll (Mark Moll)]

You should install arpack as follows:

sudo port install +openmpi -gcc46 -gcc47 -gcc45

[mamoll (Mark Moll)]

Perhaps the port should be changed so that *mpi and gcc* do no conflict with each other. The gcc* variants, if selected, can simply be ignored when one of the *mpi variants is selected. This would make for a more complex Portfile but a less confusing user experience.

I am guessing you have atlas installed. Can you try this:

sudo port install +openmpi -gcc46 -gcc47 -gcc45 -accelerate +atlas

If that doesn't work, try this:

sudo port clean arpack
sudo port deactivate atlas
sudo port install +openmpi -gcc46 -gcc47 -gcc45 +accelerate -atlas

[mkae (Marko Käning)]

Yes, I did have atlas installed and your first hint did the trick:

$ port installed atlas

Replying to mk@…:

mk, What version of OSX are you using? Would you mind trying a couple things about building with +accelerate, to see if that works? (you can use "port destroot" as mentioned above to avoid messing with your successful installation) It sounds like you were seeing the same issue vertreko reported above, which was not resolved.

Would the +accelerate build work if you deactivate atlas?

Would it work if you applied

-    configure.args-append  LDFLAGS='/usr/lib/libblas.dylib /usr/lib/liblapack.dylib' --with-blas="-lblas -llapack"
+    configure.args-append  LDFLAGS='/usr/lib/liblapack.dylib /usr/lib/libblas.dylib' --with-blas="-llapack -lblas"

configure.args-append --with-blas="/usr/lib/libblas.dylib" --with-lapack="/usr/lib/liblapack.dylib"

[mkae (Marko Käning)]

I am running Snow Leopard here.

If I deactivate atlas before building arpack I can install it successfully as well, i.e. the second suggestions in comment:54 is also a valid workaround!

OK, I haven't made those changes to the Portfile since I wasn't sure for which situation I should test it.

[dstrubbe (David Strubbe)]

I wonder if either of the two options I suggested for configure.args-append would make it work if atlas is activated, and you build arpack with +accelerate.

[mkae (Marko Käning)]

OK, I left atlas installed.

The 1st change in comment:56 does NOT work with

$ sudo port -s install +openmpi -gcc46 -gcc47 -gcc45 +accelerate -atlas

Hm, the 2nd one sounds like the Portfile just got broken. Let me be clearer about the change I meant:

-    configure.args-append  LDFLAGS='/usr/lib/libblas.dylib /usr/lib/liblapack.dylib' --with-blas="-lblas -llapack"
+    configure.args-append --with-blas="/usr/lib/libblas.dylib" --with-lapack="/usr/lib/liblapack.dylib"

Is that what you did?

[mkae (Marko Käning)]

Yep.

I am mystified as to how this can cause

configure: error: Fortran 77 compiler cannot create executables

Can you post the config.log?

[dstrubbe (David Strubbe)]

Oh, I understand. How about removing also the line:

configure.args-delete  LDFLAGS=''

and trying to build?

[mkae (Marko Käning)]

dstrubbe, with above portfile patch but also excluding the line you suggested I get something unseen so far:

[dstrubbe (David Strubbe)]

Yes, this is due to a bug in libtool apparently. You can see it has stripped LAPACK from the link line. This is what motivated my workaround in the Portfile originally.

[mkae (Marko Käning)]

This issue is not pressing for me, I just try to help solving this. So, let me know what to try next if you have time.

[michaelbartz@…]

Thanks for all the work on this. I re-read the entire ticket and realized that I was a member of the group that needed to only re-install arpack. I would like to point out that under certain conditions you cannot use the default installation for arpack. My port of octave-devel installed arpack and it required the +atlas rather than the +accelerate variant.

arpack @3.1.3_0+atlas+openmpi (active)

[dstrubbe (David Strubbe)]

mk, thanks for trying some more options. Seems like the best we can say is: for Snow Leopard, +accelerate will only work if atlas is not active.
