I made a mistake. I used mpicxx in the below commands. If I use mpiCC, it gives the exact same output.

Hi, here is the output of those commands, modified to reflect the actual tool I told boost to use, which is mpiCC, not mpicxx. What should I do with this output, and why does boost not accept it? Thanks!

Hello, I'm seeing this in my build output. I'm hoping someone can help me find out what the actual problem is. Thanks for any assistance.
