Well, I did use the Ipopt configure scripts to cross-compile Ipopt for my 
Ipod (yes, I know, it's geeky), but I remember that at some point there 
was a problem (maybe just because there was no fortran compiler for the 
compiler I used for the Ipod, so I used f2c).  In case you care, yes, 
Ipopt runs on an old Ipod with Linux, but it is so slow (the CPU doesn't 
have floating point instructions, so everything is emulated by integer 
arithmetic, and it is slow anyway) that you can see almost a line by line 
output for tiny problems...

Anyway, for cross compilation you need to specify the --host argument for 
configure, and all compilers and compiler flags that are different from 
what you get on the system you are running configure on.

For example, for my cross compilation I ran:

configure --host=arm-uclinux-elf  CC=gcc CXX=g++ ....

Cheers,

Andreas
