[Coin-ipopt] Re: IPOPT doubts

[Andreas Waechter]

Hi Luciano,

I had a look at the output you sent.  (By the way, since this is going to
a mailing list, please don't attach large files to postings - you could
send large files to my direct email address, andreasw at watson.ibm.com,
even thought I usually prefer the mailing list for Ipopt-related
questions.)

It seems to me that you tried to specify the HSL library using the
--with-hsl=... flag for configure?  I suspect that you wanted to specify
something like

-L/Ipopt/OTHERS/hsl -lhsl

but you might have forgotten to include quotations?  In other words, you
should write

--with-hsl='-L/Ipopt/OTHERS/hsl -lhsl'

On the other hand, it seems that you want to use the HSL library that is
compiled by the Ipopt makefiles.  In that case, all you have to do is to
put the source files (usually ma27ad.f and mc19ad.f) into
Ipopt/OTHERS/HSL, and the configure script should find the source files
and compile them automatically.

Since you didn't include any HSL subroutine, you got the 97 error message.
If you put the source files for the Harwell routines into the right place
and run the configure script and make again, the example should work.

I hope it helps,

Andreas
