Compiling Qt from Source on Windows - Error

[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.

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

@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.

@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!

You're welcome !
