Project ERROR: Unknown module(s) in QT: script

[SGaist]

Ok, then, did you re-run qmake after you installed qtscript ?

[Aras]

@SGaist let me back track a bit. The first time I tried this I ran sudo make install module-qscript and once that was over I went back to my qt creator build directory and tried configuring the project again and I got this error:

:~/Projects/qt-creator-build$ qmake -r ../qt-creator/qtcreator.pro
Reading /home/aras/Projects/qt-creator/src/src.pro [/home/aras/Projects/qt-creator-build/src]
 Reading /home/aras/Projects/qt-creator/src/shared/qbs/src/lib/corelib/corelib.pro [/home/aras/Projects/qt-creator-build/src/shared/qbs/src/lib/corelib]
Project ERROR: Unknown module(s) in QT: script

Now I removed my old qt source folder and downloaded a new one and built it from scratch again. Then I build the qscript module without error. However, just now I tried installing it using sudo make install module-qtscript and after some time I got this new error:

The build is really not cooperating with me. Do you have any suggestions?

[SGaist]

Did you do a complete build before qtscript ?

On a side note, if you want to avoid having to uncompress the sources each time. Just do an out of source build.

[Aras]

@SGaist yes as far as I know, I did a complete build. In my last build after I deleted the initial source folder, I did an out of source build as someone else had also recommended that to me.

I still am not able to install the qtscript module. What do you think I might be missing?

[SGaist]

Check the size of the library files created and try to build a dummy project using the QtScript module.

[Aras]

@SGaist here is a list of library files in my build folder (since they are not installed yet):

Can you explain more how I make a dummy project to test the lib? Remember I am trying to build Qt Creator, so I don't have it yet. Should I just make a simple C++ file and try to build it in command line with qcc? Or do I need to configure it with qmake?

[SGaist]

You can either use your distribution provided Qt Creator or the one from the installer.

Or just build one of QtScript examples.

[Aras]

@SGaist I rather not install the distro provided qt. I did that on another machine and it gets pretty confusing with multiple versions of Qt installed in parallel. I see if I can find a QtScript example, is there one that you know?

Edit: I found a bunch of script example projects in ~/Projects/qt-everywhere-opensource-src-5.7.0/qtscript/examples/script. The readme refers to docs, so I do not know how to build them yet, but will try to find out. But I tried just running qmake in one of the example folders and I get this error:

.../examples/script/calculator$ qmake
Info: creating stash file /home/aras/Projects/qt-everywhere-opensource-src-5.7.0/qtscript/.qmake.stash
Project ERROR: Unknown module(s) in QT: script uitools

[SGaist]

Did you call make install after you built the module ?

[Aras]

I don't think I ran make install because qmake gave me that error above. Usually it says to run install if there are no errors.

I have since installed the binary distribution of Qt so that I am not blocked by this. But I still would like to learn how to do a full install of Qt and Qt Creator from source.

[SGaist]

Looks like you built the qtscript module successfully, that's why I'm asking whether you ran make install before trying to build the example.
