[Solved]Building custom Qt from source

astodolski

@SGaist
Meaning a nmake clean?

SGaist

No: confclean.

Better yet: use a shadow build, this way you can keep your sources clean and just nuke the thing if you need to restart.

astodolski

C:\Qt\qt5>nmake confclean

NMAKE : fatal error U1073: don't know how to make 'confclean'
Stop.

Perhaps confclean is not a valid target in any of the created Makefiles?

JKSH

confclean actually doesn't exist in Qt 5. IIRC, it was hard to make it work with Qt's modular structure. See https://bugreports.qt.io/browse/QTBUG-34304 for a discussion.

Did you get the source code from git? Or did you download the source package?

astodolski

@JKSH
code.qt.io/qt using git

Reason for using clean instead of confclean referenced here thanks to @JKSH

JKSH

Assuming that you checked out the code to C:\Qt\git, use the following commands to clean your source tree:

> cd C:\Qt\git\
> git clean -dfx
> git submodule foreach "git clean -dfx"

So this is in regards to making a correction and perform a re-build? I didn't do that for the initial build.

From memory, I do a checkout, init-repository --no-webkit, and then perform the configure step and finally the call to nmake.

SGaist

My bad, old reflex from Qt 4. However, I'd recommend an out of source build, so you don't have to clean anything, just nuke the current build folder content and restart

Hi,

Not sure I understand what "out of source" means. I get the part about nuke the current folder. If what you mean is just delete the build folder and start again, then I must ask, does not doing a clean solve that?

SGaist

It literally means build from another folder outside of Qt's source tree so basically:

cd qt_build
C:\Path\to\Qt\configure

Indeed, the result is pretty much the same however It's generally faster (at least for me until now) to delete a folder than to recursively go through all Qt's modules and clean one after the other.

astodolski

@SGaist
Understood. Issue still dogging me though as to why it can't find the include files for openssl

Yes.

I didn't do that for the initial build.

Before your initial build, your folders were already clean, so you didn't need to clean them.

Yes, that sounds very useful and it works for both git and non-git sources, I'll need to try this the next time I build!

@astodolski
Can you share the full configure line you are using and the build setup summary ?

@JKSH
Out of source is just so great, you should ;)

WOW! That is amazingly faster than nmake clean. Thanks for that.

Looking at the batch file in the root folder, it looks as if that file does essentially the same thing. i.e configure.bat cd's to qtbase\configure

SGaist

Yes but it also triggers the build of the other modules, otherwise you will only build qtbase.

Can you try again with -openssl-linked ?

OK. So on my checked out build I have:
c:\Qt\qt5

You're suggesting:
cd c:\Qt\qt5
qtbase\configure

Is that correct?

There exists a configure script in both the root and the qtbase folder

SGaist

No, I'm suggesting:

cd C:\Qt\MyQt5Build
C:\Qt\qt5\configure.bat
