John,
I reduced the work you did in bug #31479 to a simple test case that could
be run by configure to verify the installed ARPACK library. I'm attaching
the file as you can probably insert it more easily into configure.ac.
When I run
g++ -o arpack_libtest -llapack -lblas -larpack arpack_libtest.cc
./arpack_libtest
to compile correctly on windows platforms, the order should be:
g++ arpack_libtest.cc -o arpack_libtest -larpack -llapack -lblas
the test passes on latest cygwin arpack-3.0.1-1
./arpack_libtest
I get a segfault. This is built against a problem version of ARPACK that
is shipped with Ubuntu 10.04 (2.1+parpack96.dfsg-2build1).
If I build against the fixed version of ARPACK in libcruft it works
g++ -o arpack_libtest -L/usr/local/lib/octave/3.4.3 -llapack -lblas -lcruft
arpack_libtest.cc
setenv LD_LIBRARY_PATH /usr/local/lib/octave/3.4.3/
./arpack_libtest
