Hi @ngjermundshaug

Sorry, I don't have an 18.04 environment to test the compilation on Melodic version. However, based on the error msg, I think it was caused by the installation of Ipopt. Did you install the ipopt properly?

Could this be solved?

Hi

I haven't looked any more at this, sorry.

Hi This error is due to missing dependency of cppad lib in your system. A simple sudo apt install cppad should do the trick
