[Coin-ipopt] Difficulities in installation on SunOS

[Andreas Waechter]

Danh,

I'm not convinced the installion was not successful.  Did you run the
example compilation with exactly the Makefile that is produced after you
run configure (In that case you should see the Fortran flags you
specified for configure's FFLAGS)?

The configure script tries to find out if there are precompiled versions
of lapack and blas installed on the system.  On SUN compilers, there is
the flag -xlic_lib=sunperf that one can specify and enables the inclusion
of optimized BLAS and LAPACK libraries.

If the configure script finished, it means that it either found these
libraries provided by SUN, or that it checked that you obtained the source
code.  In the first case, the automatically generated Makefile for the
example will include whatever flag is necessary to get BLAS (like
-xlic_lib=sunperf), and in the second case, the BLAS and LAPACK code will
be compiled when you type make install, and the objects are included in
the libipopt.a

Since the symbols are missing despite the fact that you include -lipopt,
your configure script must have determined that -xlic_lib=sunperf works.
It strongly seems to me that the reason you can't link the example is that
you don't use the right Makefile.

Hope this helps

Andreas
