Details:

I was still at sundials 2.7.1, but dev would not build anymore with
https://savannah.gnu.org/bugs/?55911. I upgraded sundials to 3.2.1, and now I
can build again, however there are some issues.


checking for sunlinsol/sunlinsol_dense.h... yes
checking whether SUNDIALS IDA includes the SUNLINSOL_DENSE linear solver...
yes
checking sunlinsol/sunlinsol_klu.h usability... no
checking sunlinsol/sunlinsol_klu.h presence... no
checking for sunlinsol/sunlinsol_klu.h... no
../octave/configure: line 77091: test: =: unary operator expected
configure: WARNING: SUNDIALS IDA library not configured with SUNLINSOL_KLU or
sunlinksol_klu.h is not usable; ode15i and ode15s will not support the sparse
Jacobian feature


line 77091 in the configure is the first line of this piece of configure
code:


  if test $octave_cv_sundials_sunlinsol_klu = yes \
     && test "x$ac_cv_header_sunlinsol_sunlinsol_klu_h" = xyes; then

$as_echo "#define HAVE_SUNDIALS_SUNLINSOL_KLU 1" >>confdefs.h

  else
    warn_sundials_sunlinsol_klu="SUNDIALS IDA library not configured with
SUNLINSOL_KLU or sunlinksol_klu.h is not usable; ode15i and ode15s will not
support the sparse Jacobian feature"

  { $as_echo "$as_me:${as_lineno-$LINENO}: WARNING:
$warn_sundials_sunlinsol_klu" >&5
$as_echo "$as_me: WARNING: $warn_sundials_sunlinsol_klu" >&2;}


  fi


I don't understand yet why it doesn't detect the sunlinsol_klu stuff since I
have in my installation dir:


./include/sunlinsol/sunlinsol_klu.h
./lib/libsundials_sunlinsolklu.so
./lib/libsundials_sunlinsolklu.so.1
./lib/libsundials_sunlinsolklu.so.1.2.1
