Issue building qt 5.12 from latest git repo

code_fodder

@kshegunov good idea - I will do that.

While I am doing that, did you see this before: https://forum.qt.io/topic/95040/build-qt5-from-git-with-msys2-fails-on-wrong-includes

I just wander if its relevant. But I am not using msys or anything... just wanted to get your thoughts...

kshegunov

I don't know, it may be. I too use strawberry pearl when I do my windows testing (I develop and use Linux principally). You could try it if anything else doesn't work. It'd also allow you to run the repo's perl init script.

code_fodder

@kshegunov well, i just did the super squeaky clean, I even opened using dos cmd.exe just in case conemu was causing an issue (using mingw-w64.bat to set the tool chain path) ... it was a thoroughly horrid experience, I don't recommend it! (why Microsoft, oh why is your command prompt the same one from the 1980's?!?)

but alas, I got the same result (I was following what you did this time - i.e. exactly the same config. As mentioned in that other post (if I change #include <QVector> to #include "qvector.h" that file does compile - but then I just hit another issue later...

I am sort of out of ideas - I have had this all working on linux many times, but I just can't seem to get to grips with the windows builds of late : (

btw guys your support / ideas are much appreciated (and @SGaist)

SGaist

Did you check whether the QXXXX files were generated ?
Also, can you test if you have the same problem with 5.12.1 ?

code_fodder

@SGaist Where would these be? (I mean where should I look)

I am about to do somthing a bit crazy - and install windows 10!... juuuuust in case... that might take me a little while, but I should still be able to check these QXXX files...

Once I do that, yes I will try to build 5.12.1 (I assume that is a git branch)

code_fodder

In my build directory I did this (in the qtbase sub folder):

D:\install\Qt\qt5_static_build\qtbase>find -name "QVector*"

D:\install\Qt\qt5_static_build\qtbase>find -name "qvector*"
./include/QtCore/qvector.h

so I found qvector.h, but not QVector

SGaist

So this means that the forward headers are not generated.

Do you have perl installed ?

code_fodder

@SGaist yes:

D:\install\Qt\qt5_static_build\qtbase>perl --version

code_fodder

So I am currently doing: perl init-repository --module-subset=essential

I had assumed that was just the equivalent of git submodule update --init --recurive

code_fodder

@SGaist ... damn, that did not compile still. Also in my out of source build folder I still can't find "QVector*" ... Is there some way to force the generation of QXXX files?

kshegunov

Would you try strawberry pearl? I imagine this is related to the link you posted (about msys) after all.

code_fodder

@kshegunov yes I would try that! - I was just about to try 5.12.1... but that is probably not the issue. I will go look for strawberry perl...

code_fodder

@kshegunov I assume (just downloading it) that you want me to run the perl init repo line again with strawberry perl?

code_fodder

So I just did the init repo with strawberry perl. it did stuff, but gave me a strange warning at the end. Anyway, I am continuing with the config / build...

Ok, so configured (statically as before without -no-pch) and hit make -j8... now the build has been going for far longer then before!

After the config I still could not see the QXXX files, but once the build started (its still going) I got:

D:\install\Qt\qt5_static_build>find -name "QVector*"
./qtbase/include/QtCore/QVector
./qtbase/include/QtCore/QVectorIterator
./qtbase/include/QtGui/QVector2D
./qtbase/include/QtGui/QVector3D
./qtbase/include/QtGui/QVector4D

So, this looks like the issue... what the difference its between the two perls - I have no idea! - but its looking very good at the moment. I think I can close this issue becuase the specific build error I had is gone (I may still have other troubles - but they can be in a new issue if required).

Guys @SGaist @kshegunov - you have both been great - can't upvote enough...

code_fodder

btw - I did get another error few minutes later... but I have a few things I can try (its another file that can't be found) but if I struggle I will start a bew post! - setting this as resovled

code_fodder

err.... actually one last one - I forgot how you set the question to "resovled" - I am sure it used to be a tag in the heading...?

code_fodder

@code_fodder found it!....
