[Coin-ipopt] hanging TRON

[Andreas Waechter]

Hi Kevin,

I checked out if I could reproduce your hanging TRON, and I think I fixed
it.  The problem was that the constraints become again undefined (Nan or
something like that), and TRON - if compiled with g77 - didn't like that
(it actually seems to work fine with the Intel compilers...).

In order to fix your local copy, either type 'cvs update' (if you used CVS
to download IPOPT), or just get the file

COIN/Ipopt/SOURCES/OTHERS/TRON/dtron_p.patch

directly, e.g. go to

http://www-124.ibm.com/developerworks/opensource/cvs/coin/COIN/Ipopt/SOURCES/OTHERS/TRON/dtron_p.patch?rev=1.3&content-type=text/x-cvsweb-markup

and click on download.

After you got the correct file, go to

COIN/Ipopt/OBJECTS/OTHERS/TRON

and type

make distclean

After that just go back to

COIN/Ipopt/OBJECTS/IPOPT/CUTEr_interface

and type

make

to get your CUTEr installation up to date.


Thanks again for letting me know about it!

Cheers

Andreas
