Do you have any idea on how to solve this issue @jgillis ? Could it be a the Ipopt version ? I tried the last version of Ipopt I tried...

I managed to solve the problem. In fact the header are in include/coin-or . I thus added it to my $CPATH.

It seems that doing "gcc -fPIC -shared -g" (instead od -O3) solved the problem. It is ok as temporary solution for me.
