[Solved]Building custom Qt from source

SGaist

Hi,

Yes, it's possible, but first you have to get OpenSSL for windows

astodolski

@SGaist

Yes I do have it. In the configure options I point to the include folder for OpenSSL as well as the lib folder

SGaist

Just C:\OpenSSL_win32\include or C:\OpenSSL_win32\include\openssl ?

astodolski

@SGaist

Not exactly but similar. The include is: C:\openssl-1.0.2d\include\openssl

SGaist

Then the path is one level too deep. You need to use C:\openssl-1.0.2d\include\

astodolski

@SGaist
Ok, I actually had one level down as you shown and the error persists. That is, ...\include\ and ...\include\openssl. Both were tried and yet had errors:
fatal error C1083: Cannot open include file: 'openssl/ssl.h': No such file or directory (access\qnetworkreplyhttpimpl.cpp)

SGaist

Might be a silly question but did you pass the corresponding -I and -L arguments to configure ?

astodolski

@SGaist
Yes. A part of the configure options is shown below:
-ssl -openssl -I C:\openssl-1.0.2d\include -L C:\openssl-1.0.2d\lib

SGaist

When doing the -I and -L corrections, did you do it from a clean state ?

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.
