On a CentOS7.9 system the system GCC should be 4.8.5 and that has no problem building GCC 11.3.0
GCC 2.2 was used back in the days of CentOS 4 or so ________________________________________ From: [email protected] <[email protected]> on behalf of Loris Bennett <[email protected]> Sent: Thursday, September 21, 2023 16:09 To: easybuild Subject: [easybuild] GCCcore-11.3.0.eb: system gcc too old Hi, Up until recently we had a homogenous cluster and built software for a single microarchitecture. We now have new nodes with different CPUs need to rebuild a large number of packages. However, rebuilding GCCcore-11.3.0.eb is failing with the following error: configure: error: *** A compiler with support for C++11 language features is required. The system GCC is 2.20 (it is a CentOS 7.9 machine). On the same machine it was apparently possible to build GCCcore-11.3.0.eb in the past. So do I now have to build an older GCCcore, which EasyBuild can then subsequently use to build 11.3.0, or how do I get around this issue?
