<br><font size=2 face="sans-serif">Dear All,</font>
<br><font size=2 face="sans-serif"> </font>
<br><font size=2 face="sans-serif">I have downloaded the latest versions
(tarball) of Ipopt and version 4.7.3 of MUMPS. I managed to configure and
compile it using MSVC 8.0 and Intel Fortran 9.1 using cygwin.</font>
<br><font size=2 face="sans-serif">When I run the testproblems with MA27
it works but when I set the linear solver flag to mumps it gives some error
messages, indicating that i dont have MUMPS. As far as I can see, it never
tries to call MUMPS but halts in the initilization stage. A typical error
is the following:</font>
<br>
<br><font size=2 face="sans-serif">C:\Solvers\IpoptDir\build\Ipopt\test>hs071_cpp</font>
<br><font size=2 face="sans-serif">Exception of type: OPTION_INVALID in

to get the value of Option: mumps_pivtol. It is not a valid registered
option.</font>

<br>
<br><font size=2 face="sans-serif">When I look in the file ipopt_config.h
in the catalogue C:\Solvers\IpoptDir\build\Ipopt\inc it (the configuration
I suppose) has set the flag </font><font size=2>COIN_HAS_MUMPS</font><font size=2 face="sans-serif">
=1</font>
<br><font size=2 face="sans-serif">Is there some other manual changes that
needs to be done or what can be the problem?</font>
