Not sure this is related to MPICH. One suggestion from StackOverflow (https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwjd...) seems to suggest this is an upgrade/install issue. -- Hui Zhou From: Omid Bagheri via discuss <[email protected]> Date: Monday, May 24, 2021 at 12:31 PM To: [email protected] <[email protected]> Cc: Omid Bagheri <[email protected]> Subject: [mpich-discuss] Build MPICH Error Hello, I am installing MPICH Version 3.4.1 on CentOS Linux 8 and I get an error in building MPICH while the configuration was successful. I was wondering if you can help me with this.
