[Coin-discuss] Cross-compiling COIN projects (Osi)

[Andreas Waechter]

Hi again, Stefan,

I had a look at this.  Are you sure that you need to use the --target 
option?  It is my impression that --host is meant for cross compilation. 
I believe that the run test in configure are switched off if you use 
--host.

I can't try this right now since I don't have access to a system with 
a cross compiler.  But at some point I had successfully compiled Ipopt (so 
that it could run on my Ipod...)

Regards,

Andreas
