[Scip] Compiling scip-3.0.2 with Ipopt-3.11.7 on MAC OSX 10.9.2

[Stefan Vigerske]

Hi,

it seems that the installation of the HSL sources did not work.
Even though the Ipopt contains the libcoinhsl.dylib library, it probably 
contains none of the linear solvers. Ipopt then tries to load one 
dynamically at runtime from a library libhsl.dylib.

The instructions you refer to (HSL/releases/1.3.3/INSTALL.HSL) are for 
old HSL sources (< 2011, I think). These sources have to be put into the 
ThirdParty/HSLold subdirectory of Ipopt. However, using these is deprecated.
If you have downloaded the HSL sources recently, you should follow the 
instructions in ThirdParty/HSL/INSTALL.HSL. Essentially, you have to 
follow the links at http://www.hsl.rl.ac.uk/ipopt to register and
obtain an archive coinhsl-x.y.z.tar.gz.
Then unpack this archive via
   gunzip coinhsl-x.y.z.tar.gz
   tar xf coinhsl-x.y.z.tar
Finally, rename the directory coinhsl-x.y.z to coinhsl, or set a 
symbolic link:
   ln -s coinhsl-x.y.z coinhsl


After building Ipopt, running make test shows you whether your Ipopt 
installation is working.

Hope that helps,
Stefan

PS: This discussion fits better to the Ipopt mailing list, but we can 
also continue this off-the-list.
