[Ipopt] Compilation error, .... /libcoinhsl.so: undefined reference to 'xxx'

[Andreas Waechter]

Yes, Ubuntu does provide BLAS implementations.  I recommend to make sure 
to install a good implementation such as Atlas (which is available from 
Ubuntu).  This is probably not as highly tuned for the particular 
machine where one installs this precompiled Atlas (ideally, you compile 
it on your machine to have it really tuned to the particular CPU, Cache 
size etc), but should be better than the netlib reference implementation.
