Currently we download and use the big download of qt[1] and frankly I'd rather not. Qt does also ship in smaller bits[2], 32 if I counted correctly. I propose we package the submodules and over time we go through the packages that use qt and switch out the monolithic qt for just the parts that the program actually uses. It makes it less daunting to build, should make the closures smaller, and means that if a submodule fails to build on an architecture then they only lose that module, not all of qt. > > [0] http://hydra.gnu.org/build/1114596 > [1] https://download.qt.io/official_releases/qt/5.6/5.6.0/single/qt-everywhere-opensource-src-5.6.0.tar.xz > [2] https://download.qt.io/official_releases/qt/5.6/5.6.0/submodules/ > Finally got around to building qtbase out, took me 6 hours total on my machine. So since hydra[1] says it takes 7:15 it's a bit shorter. I haven't had a chance yet to try out qmake on the other modules or to try to optimize the build yet. One of the things I did want to try was replacing python2 with python-wrapper and enabling parallel-builds. I opted for straight out copying qt-5's build rather than inheriting so it'll be easier to remove it if/when we're ready, and I updated the license based on the text shown during build-time. I've attached what I have so far if anyone else wants to take a look at it while I'm working on it. Also very worthy of note, qt-5.5.1 is listed at 288 MB, and qtbase-5.6.0 is all of 85 MB. efraim@debian-netbook:~$ du -sch /gnu/store/r9bpiyz2w5bkavnx3s1ffxpgc51wa9z5-qtbase-5.6.0/* 6.6M /gnu/store/r9bpiyz2w5bkavnx3s1ffxpgc51wa9z5-qtbase-5.6.0/bin 560K /gnu/store/r9bpiyz2w5bkavnx3s1ffxpgc51wa9z5-qtbase-5.6.0/doc 25M /gnu/store/r9bpiyz2w5bkavnx3s1ffxpgc51wa9z5-qtbase-5.6.0/examples 20M /gnu/store/r9bpiyz2w5bkavnx3s1ffxpgc51wa9z5-qtbase-5.6.0/include 30M /gnu/store/r9bpiyz2w5bkavnx3s1ffxpgc51wa9z5-qtbase-5.6.0/lib 2.5M /gnu/store/r9bpiyz2w5bkavnx3s1ffxpgc51wa9z5-qtbase-5.6.0/mkspecs 2.6M /gnu/store/r9bpiyz2w5bkavnx3s1ffxpgc51wa9z5-qtbase-5.6.0/plugins 85M total [1] http://hydra.gnu.org/build/1202329 -- Efraim Flashner אפרים פלשנר GPG key = A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted
