A few days before, the default solver just worked normally and well, but today I tried to re-run the examples from tutoral with the default solver, but the following persistent error pops up. I want to know what wrong happened in the configuration and how to fix that. Thank you.
Thank you Charles. There are no more words after “warning: the solver test failed with the following error:” no details following any more.
The problem disappeared after I switch off the SMS mode and re-activate the program. It is weird, I want to know whether this problem is related to SMS mode. Thank you.
