[Coin-ipopt] an error during building the external HSL

Hi Bruce,

It seems that you downloaded the Harwell subroutine source code
incorrectly.  The files seem to contain HTML stuff.

If done correctly, the files should start with some comment lines (where
the first letter in each line is a star or a 'C'), and then something like



You probably need to try to download the code again from the Harwell
webpages.  This can be a bit tricky; if I remember correctly, you need to
basically click on the download button (or something like this), and the
Fortran code will show up in our browers window.  After that, you choose
"Save as", and safe it as ma27ad.f (or whatever subroutine you obtain).

I hope this helps,
