If you look into the Road Map<br>page of QE: <a href="http://www.quantum-espresso.org/road-map">http://www.quantum-espresso.org/road-map</a><br>you will notice, under "Things you can do to help QE""<br><br>Improve packaging<br><br>* help with existing Debian packages (available in DebiChem)<br>* produce binary packages in other formats: RPM, Mac OS-X, Windows<br>(bleah!) executables<br><br>I am ready to remove the "(bleah!)" if this helps a Windows<br>executable to materialize!<br></blockquote><br>i don't mind producing windows binaries, for as long as i don't have<br>to use windows to build them. i'm doing this for LAMMPS now for quite<br>a while and have streamlined the process substantially. the amount of<br>problems and complaints from windows users has dropped almost to zero<br>and those windows packages are a relief for every tutorial, since<br>people can use their own machines. the one LAMMPS developer that is a<br>devoted windows user even confirmed that my cross compiled binaries<br>work better and much faster than his "native" compilations (based on<br>cygwin). i can even throw in OpenMP support for good measure (may have<br>to have a look at OpenBLAS for that...).<br><br>there is one question, though: what would be the naming conventions<br>for the windows executable? i.e. would you prefer: pw.exe, pw.x.exe,<br>or qe-pw.exe or something else? pw.x.exe is probably the least<br>disruptive, but i don't know (yet) if this can be made to work.<br><br>rpms is also not a big deal. i've been doing this alongside the<br>windows builds since late spring as well. i have a box in philly that<br>has 12 virtual machines with build environments for fedora 17/18/19,<br>centos 6.x, opensuse 12.3 and windows cross-compilation. each for<br>32-bit and 64-bit and then a small little webserver that hosts those<br>binaries. takes only a few mins to initiate a new build currently, but<br>will be automated at some time.<br><br>check out:<br><a href="http://git.icms.temple.edu/rpm/windows.html">http://git.icms.temple.edu/rpm/windows.html</a><br>and:<br>http://git.icms.temple.edu/rpm/index.html<br><br>following the same strategy would be straightforward to adopt for QE.<br>exotic compile time features would be left out and optional packages<br>could be packages as add-on rpms packages.<br><br>just let me know or tell others to let me know what the preferred<br>approach would be. QE builds would be considerably less of an effort,<br>since the releases are - unlike with LAMMPS - infrequent. however,<br>those semi-automatic builds have helped a lot to identify build and<br>programming issues ahead of everybody else.<br><br>thanks,<br> axel.<br><br><blockquote type="cite"><br>P.<br>--<br>Paolo Giannozzi, Dept.
