Hi,<br><br>We had issues with 4.1 series compilers, but we are not longer sure if there really<br>are issues in 4.1.2 and 4.1.3. I would surely avoid 4.1.0 and 4.1.1.<br>But we found that one or two issues in Gromacs only showed up with 4.1.2 and 4.1.3,<br>but there were problems in Gromacs, not gcc.<br>So we are not 100% sure, but version 4.5.1 probably works fine with gcc 4.1.2.<br><br>Berk<br><br>> Date: Tue, 5 Oct 2010 20:03:41 +0530<br>> From: rashmi@chem.iitb.ac.in<br>> To: gmx-users@gromacs.org<br>> Subject: [gmx-users] Installation of gromacs on a cluster with gcc version 4.1.2<br>> <br>> Hi All,<br>> <br>> I want to install Gromacs 4.5.1 version on a cluster system (high<br>> performance computing facility) in our institute. I don't have access to<br>> root and thus, I have to install gromacs in my home directory.<br>> <br>> The problem is that, the cluster has CentOS 5.4 as the operating system<br>> and the gcc version is 4.1.2.<br>> <br>> Gromacs site says that gcc 4.1.x and above are broken compilers and<br>> gromacs should not be compiled using them.<br>> <br>> So I plan to install a compatible version of gcc, for eg. gcc-4.0.4, in my<br>> home directory and then install gromacs 4.5.1 using this compiler. Will<br>> this be ok?<br>> <br>> I am asking this question because the new gcc i will install will be<br>> compiled with the so called broken compiler version gcc 4.1.2 (which i<br>> cannot change). Is this the correct way to ensure that i do not compile<br>> gromcas with a broken compiler.<br>> <br>> Please do reply.
