That looks like an good way of dealing with switching between different architectures. However, I am not yet quite that far. My question was more to do with how to actually rebuild the software in a second branch. If I change EASYBUILD_INSTALLPATH and MODULEPATH as described abouve and then run EasyBuild with force I get, say, the following: [build@a001 ~]$ eb Bison-3.8.2.eb --robot --force --dry-run == Temporary log file in case of crash /tmp/eb-akrn565i/easybuild-0vsmv95q.log == found valid index for /trinity/shared/easybuild/software/EasyBuild/4.6.2/easybuild/easyconfigs, so using it... == found valid index for /trinity/shared/easybuild/software/EasyBuild/4.6.2/easybuild/easyconfigs, so using it... Dry run: printing build status of easyconfigs and dependencies * [x] /trinity/shared/easybuild/software/EasyBuild/4.6.2/easybuild/easyconfigs/m/M4/M4-1.4.19.eb (module: M4/1.4.19) * [F] /trinity/shared/easybuild/software/EasyBuild/4.6.2/easybuild/easyconfigs/b/Bison/Bison-3.8.2.eb (module: Bison/3.8.2) How to I get EasyBuild to build M4 automatically as well?
