Sorry for being late to reply. There was a typhoon last weekend, I didn't come to my lab. I downloaded the deal.II 7.1.pre code under development. And try to configure like this: ./configure But I got this error message: huyaoyu@ubuntu:~/Downloads/deal-dev$ ./configure Configuring deal.II version 7.1.pre configure: error: cannot run /bin/bash contrib/config/config.sub The very error appeared no matter I put other arguments or not. I Googled the error message but did not find a solution. Do you know what is going on here? Best.
