error with cppad when performing stage simulation #3

Closed fighterxi closed 6 years ago

fighterxi commented 6 years ago

Sorry to disturb you again, I found this problem when I performed the "roslaunch hypharos_minicar HyphaROS_Simulation_Stage.launch". How can I solve this problem?
The following is the error messages. Looking forward to your reply.

Hi @fighterxi Sorry for the late reply. I think the cause of your problem came from "CppAD", it depends on how you install & link your ipopt solver. (ref: https://github.com/udacity/sdc-issue-reports/issues/827) So, it is hard for me to help you in this situation. However, I will release virtual box image recently, so in this case, you can test our simulation on it.

Hi @jim1993 ， thank you for your reply, I reinstalled Ipopt, and no longer have the above problems.

@aogrcs Hi, sorry for the late reply. I followed this " hypharos_minicar/document/ipopt_install/ipopt_x86_install_tutorial.md." to install Ipopt .
