I just tried to do a full build, but my system stopped "out of memory" in Qt3D.

Disk used so far: 23 GB.

I didn't even include the QtWeb* modules, see below.

perl init-repository --module-subset=default,-qtwebkit,-qtwebkit-examples,-qtwebengine
./configure -developer-build -opensource -nomake examples -nomake tests -confirm-license

Maybe I can get it to fully build tomorrow.

@VRonin
That would an epic good idea.
We use this method exclusive at work and sit a huge timer saver.

SGaist · 30 Jul 2018, 20:30

What about having it pre-configured and people can start compiling it after they did the modifications they want ?

Another possibility could be to provide a docker container ?

kshegunov · S SGaist 30 Jul 2018, 19:13

Will preconfiguring work, as configure does compile qmake?

SGaist · wrote on 30 Jul 2018, 20:34

Good point, what could be done is to pre-configure Qt, clean everything and just keep the configuration files needed to re-trigger Qt's build.

@aha_1980
What about building only qtbase or the essential set of modules? That should be more manageable, even if somewhat constraining?
Something like the following configuration:

$> perl init-repository --module-subset=essential
$> ./configure -developer-build -opensource -nomake examples -nomake tests -confirm-license
$> make module-qtbase
$> make module-qtquickcontrols2
$> ...

Ehm, you do need qmake to retrigger the build, or did you mean something else? My concern is with the qmake's paths that are compiled into the binary, maybe patching them would do the trick?

SGaist · 30 Jul 2018, 21:32

config.status and config.opt are all that are needed.

kshegunov · S SGaist 30 Jul 2018, 20:55

Needed for? Triggering configure?

SGaist · wrote on 30 Jul 2018, 21:53

Re-trigger configure using the set of parameter you original passed. In the absolute, config.opt is enough as config.status just calls configure with the -redo option.

aha_1980 · 31 Jul 2018, 07:10

Full build finished with make -j 1 ;)

@aha_1980 Thanks!

@SGaist and @kshegunov My idea was to pre-configure and even make. That's really the time saving part. The rest can literally be included in a bash file, it's not really that taxing.

That's actually another great idea

aha_1980 · wrote on 31 Jul 2018, 07:26

As someone that has not used Docker before: it is not as cross-platform as VirtualBox, i.e. you can use a Linux docker only in a Linux environment, not Windows, right?

mrjj · wrote on 31 Jul 2018, 09:32

Hi
Dockers can be used in windows too but no gui possible as far as i know.
So VM would be so much more flexible and cross platform.
also dockers requires user to learn how to use them ( new commands, integration etc)
where as WM is still just a normal linux.

VRonin · 31 Jul 2018, 09:54

Ok, so:

VM over docker

Open issues

"pre-config & make" or "pre-config and delete unnecessary stuff"
where would it be appropriate to host such a big file?
how often should it be updated and what would be the best way to do it?

Don't forget the traffic that is generated when downloading...

For me and my limited networks speed, even downloading such a big file takes several hours.

Another good one :) For now, I'd set it to the tip of qt5 5.11 branch, so you could do fixes easily and even push something to dev/5.12 with good chance it can be cherry-picked without conflict.

That would mean you'd have to renew it in approx. half a year, when 5.12 is out (Given that the average user downloads no beta releases anyway).

mrjj · 31 Jul 2018, 10:06

Hi
regarding hosting.
How big is image ?

aha_1980 · M mrjj 31 Jul 2018, 10:04

@mrjj Expect something between 20 and 40 GB (depending if we keep the compile artefacts or not).

kshegunov · V VRonin 31 Jul 2018, 09:40

@VRonin said in Gerrit Contributions:

No clue, but if you become desperate I can clear you 100-200 GB on my disk, however my connection isn't really that fast (40Mb outgoing).

mrjj · 31 Jul 2018, 10:34

Well
https://www.pcloud.com/
give 20 GB for free.
maybe we can compress it.
I will try to see if i can find their markting person and ask if they could donate
100 GB to Qt forum.

kshegunov · 31 Jul 2018, 10:35

A classmate of mine works for that company, I could make a separate inquiry about it ...
