[Coin-ipopt] make error in 'initparams.F'

Hi Hans

Thanks for sending your message about your compilation problem.

Your compiler is right - according to the Fortran 77 standard, the DATA
statements have to come after all declarations (so far, no compiler I had
used has complained about it).  I just committed the corresponding changes
(in find_param.f and initparams.F).  In order to get the new source, you
could wait for tomorrow's Ipopt tarball (they are created only once a day
around midnight), or if you don't want to wait you can get them via CVS,
e.g. from the CVS web interface at




It seems that you are using a compiler different from the GNU compiler
(which would not have complained about the order of DATA statements), your
compiler executable is /usr/bin/fort77 on your machine.  The Ipopt code is
written in Fortran 77, but there are a few non-standard things that I used
- I hope your compiler will not choke on them.  If it does, you could tell
your configuration script explicitly to use the GNU compiler, e.g. by

./configure F77=g77 [and the rest of your options here)

after a `make clean'

Anyway, I hope you are now able to compile the code.
