[Ipopt] Rép : Ipopt compilation on mac OS X 10.6

[Sylvain Auliac]

The problem with g95 was an history about mixing dynamic and static library... for a reason, the version coming from macport does not build a libf95.dylib file. I have removed all the ipopt dynamic library and added a --enable-static to Mr Zimmerman "step-by-step" configuration and it seems to work now. This does not tell us why my attempts with gfortran have always failed but I think I'll stop my investigation on that matter for the moment. 
Thanks for all the help!

If I only do that, I get this error when I type "make test" when tests are run. I have then tried several flags combination from this troubleshooting page, I only have better results when I also add LDFLAGS="-flat_namespace" . With that, the console displays a succes message when I run the test. But still the executable from the exemples folder send this "_g95_filename" error (not to speak about code of my own). This is somewhat weird... I use gcc for c/c++ compilation and g95 for the fortran.
