I'm running octave-control 3.0.0, which is waiting to be committed to MacPorts: #49540 under octave 4.0.0 (#48622). However, it experiences the same build failure under octave 3.8.2 as does version 2.8.5.

The release notes for control 2.8.0 only mention that it had an compatibility fix for octave 4.0.0, but does not mention that it no longer supports octave 3.8.2.

I have e-mailed the octave-maintainer list.

This is a showstopper for me, since the very popular octave-signal requires octave-control.

I see that the ​release notes for slicot state that calls to the deprecated DGEG have been replaced with DGGES so maybe the resolution is to update the version of slicot used in octave-control.

[Schamschula (Marius Schamschula)]

This issue seems to be connected with LAPACK. Are you using octave +atlas? If so what version of atlas?

[hraftery@…]

I found a workaround: the slicot source package can be manually patched to replace the deprecated calls, and the octave-control will build just fine.

After a failed {{{sudo port install octave-control}} execute the following:

$ cd `port dir octave-control`/work/
$ sudo rmdir control/install/
$ sudo rmdir control/
$ sudo -u macports tar zxvf .tmp/control.tar.gz
$ cd control/src
$ sudo -u macports tar zxvf slicot.tar.gz
$ sudo -u macports sed -i '.orig' 's/DGEGS/DGGES/g' slicot/src/SG03AD.f slicot/src/SG03BD.f
$ sudo -u macports sed -i '.orig' 's/DLATZM/DORMRZ/g' slicot/src/AB08NX.f slicot/src/AG08BY.f slicot/src/SB01BY.f slicot/src/SB01FY.f
$ sudo -u macports sed -i '.orig' '/tar -xzf slicot.tar.gz/d' Makefile 
$ cd ../../..
$ sudo port install octave-control

I elected not to provide a patch file because un-tarring slicot makes for a 17MB diff.

This is clearly just a workaround, as the non-deprecated versions are not guaranteed to be backwards compatible. In fact, now that I've signed up to download the latest slicot, I see that the call to DGEGS/DGGES now looks like this:

IF ( LDWORK .LT. MINGG ) THEN
C
C           Use DGEGS for backward compatibilty with LDWORK value.
C           ( Workspace: >= MAX(1,4*N) )
C
            CALL DGEGS( 'Vectors', 'Vectors', N, A, LDA, E, LDE, ALPHAR,
     $                  ALPHAI, BETA, Q, LDQ, Z, LDZ, DWORK, LDWORK,
     $                  INFO1 )
         ELSE
C
C           Use DGGES. The workspace is increased to avoid an error
C           return, while it should not really be larger than above.
C           ( Workspace: >= MAX(1,8*N+16) )
C
            CALL DGGES( 'Vectors', 'Vectors', 'Not ordered', DELCTG, N,
     $                  A, LDA, E, LDE, I, ALPHAR, ALPHAI, BETA, Q, LDQ,
     $                  Z, LDZ, DWORK, LDWORK, BWORK, INFO1 )
         END IF

I was not able to get octave-control to compile with this latest version of slicot, so the workaround remains my best solution.

Replying to mschamschula@…:

This issue seems to be connected with LAPACK. Are you using octave +atlas? If so what version of atlas?

Yes, the default octave port seems to be the +atlas one (which took a loooooong time to build). I simply did port install octave and got:

octave @3.8.2_14+atlas+gcc5+glgui (active)
atlas @3.10.2_2 (active)

[ifernandolopez (Fernando López Hernández)]

The workaround of hraftery has failed for me with this message:

Error: Requested variants "+gcc5" do not match those the build was started with: "+gcc49".

But worked after issuing:

$sudo port install octave-control +gcc49

[fredowski]

I tested yesterday with octave-devel-release (which is 4.0.1). There I can install the package.

[Schamschula (Marius Schamschula)]

Fixed in r153772.
