Compiling Qt from Source on Windows - Error

[PrateekKhatri]

Hi,

I conifgured as required and then ran qmake under qtbase/bin/ and ran "jom" again.

I was able to finish the build with the following output:

Updating 'qtxmlpatterns_it.qm'...
Updating 'qtxmlpatterns_hu.qm'...

After this It came back to the prompt. I assume that the build is finished as there were no messages related to it being finished or throwing errors.
EDIT: I did call jom install after this and waited for it to finish.
Next I installed Qt Creator Enterprise Edition and configured the Kit to point to the qmake under the newly built folder.

However I am getting the following error:

11:35:28: Running steps for project TestCanBus...
11:35:28: Starting: "C:\Qt\Qt5.10\qtbase\bin\qmake.exe" C:\Users\prateekkhatri\Documents\TestCanBus\TestCanBus.pro -spec win32-msvc "CONFIG+=qml_debug"
Project ERROR: Unknown module(s) in QT: serialbus
11:35:28: The process "C:\Qt\Qt5.10\qtbase\bin\qmake.exe" exited with code 3.
Error while building/deploying project TestCanBus (kit: Desktop)
When executing step "qmake"
11:35:28: Elapsed time: 00:00.

It is not able to identify QCanBus under the qtserialbus folder.
My .pro file has the following entries:

QT       += core gui
QT       += serialbus

It'll be really awesome if I can get this working. I would really appreciate any help.

Also, I tried adding QSerialPort by adding it in project and including it in one of my source files - it gave the same error. For some reason The Qt Modules are not being found.

Thanks!

Did you call jom install after building ?

[PrateekKhatri]

@SGaist

Yes I did.

[SGaist]

Good, did you do that in qtbase or the Qt sources top level folder ?

[PrateekKhatri]

@SGaist
I did it in the top-level folder or one level above qtbase.

[SGaist]

Check the content of the lib folder, if nothing QtSerialBus can be found, the quickest would be to build/install the module by hand. You can go in the module sources and call qmake/jom/jom install.

@SGaist

C:\Qt\Qt5.10\qtserialbus\lib>ls
Qt5SerialBus.dll  Qt5SerialBus.exp  Qt5SerialBus.lib  Qt5SerialBus.prl  Qt5SerialBusd.dll  Qt5SerialBusd.exp  Qt5SerialBusd.ilk  Qt5SerialBusd.lib  Qt5SerialBusd.pdb  Qt5SerialBusd.prl  cmake

These are the contents that I find in qtserialbus directory and

C:\Qt\Qt5.10\qtserialbus\lib>cd cmake

C:\Qt\Qt5.10\qtserialbus\lib\cmake>ls
Qt5SerialBus

C:\Qt\Qt5.10\qtserialbus\lib\cmake>cd Qt5SerialBus

C:\Qt\Qt5.10\qtserialbus\lib\cmake\Qt5SerialBus>ls
Qt5SerialBusConfig.cmake  Qt5SerialBusConfigVersion.cmake  Qt5SerialBus_PeakCanBusPlugin.cmake  Qt5SerialBus_SystecCanBusPlugin.cmake  Qt5SerialBus_TinyCanBusPlugin.cmake  Qt5SerialBus_VectorCanBusPlugin.cmake

C:\Qt\Qt5.10\qtserialbus\lib\cmake\Qt5SerialBus>

I did run jom install inside this folder, but Qt Creator still can't see this module for some reason.

[SGaist]

AFAIK, you should have all the libraries needed in qtbase/lib once the installation is done

[PrateekKhatri]

@SGaist
I could't see anything Qt5SerialBus inside the lib folder under qtbase. Any suggestions on how to get this working?

I manually copied the contents of qtserialbus/lib into qtbase/lib and the contents of qtserialbus/lib/cmake into qtbase/lib/cmake, but Qt Creator doesn't seem to find the library still.

@PrateekKhatri said in Compiling Qt from Source on Windows - Error:

\usr\local\Qt-5.10.0

Do you have a folder like that somewhere on your machine ?

[PrateekKhatri]

@SGaist
Yes it is there in my C:\ . And I do see Qt5SerialBus related files in the lib folder. Is there a reason why it would automatically move everything to a folder \usr\local\Qt5.10.0\ ?

[SGaist]

The path is a bit surprising but you should use the -prefix option when you want your build to be located somewhere precisely, otherwise, Qt has it's defaults. But again, that's rather a *nix path than Windows.

[PrateekKhatri]

@SGaist
I was wondering the same thing. Oh well, I pointed the qmake under usr/local/Qt5.10.0/bin and everything magically works now :)

Thank you so much @SGaist !

You saved my life!

[SGaist]

You're welcome !
