Building qt 5.9.7 on CentOS 7 completes but qtsvg seems to be missing

SGaist

@yryu4526 said in Building qt 5.9.7 on CentOS 7 completes but qtsvg seems to be missing:

Could you explain a bit further, what do you mean by "installed in your custom build"? Two messages up I pasted the qt section of the build profile for the other app.

Take a look into the folder that was populated after you called "make install". Do you find anything related to QtSvg ?

yryu4526

That would be, I believe, /usr/local/Qt-5.9.7/lib and it does contain libQt5Svg.so.5.9.7.

SGaist

Ok, do you have the same issue if you create a small dummy project using that module ?

yryu4526

I do not know, I do not have the skills to create a new project. I asked earlier if there are any test programs in qt that I can use to check the status post-compilation?

Hi
You can just use Creator and the menu File->"New File Or project"
and then
alt text

then add
QT += svg
in the pro file and see if that compiles.

just in case you dont have creator.
here is default project created with thw wizard
https://www.dropbox.com/s/vvz5s4yhka68uui/justDefualt.zip?dl=0

I downloaded the file into a new directory, ran "qmake -r justDefualt.pro" and got the following output:
Info: creating stash file /root/test/.qmake.stash
Project ERROR: Unknown module(s) in QT: svg

Note that I am running as root in a docker container, not on the main machine itself.

SGaist

And the qmake is from your self compiled Qt ?

yryu4526

Correct, it's located in /root/qt5-build/qtbase/bin. I am wondering, since I am doing this in a docker container, there might be some configuration issue?

This is the output after running the first ./configure command (../qt5/configure -opensource -prefix /usr/lib64 -nomake examples -skip qtquick1 | tee -a /qt-build.txt)

Qt is now configured for building. Just run 'gmake'.
Once everything is built, you must run 'gmake install'.
Qt will be installed into '/usr/lib64'.

Is there something above that does /not/ look correct?

SGaist

Did you call make install ?
You can also skip building the tests.

I find it strange that QtSvg is not listed. Did you parse them tests logs to see if anything has failed for it ?

Did you try to manually build it after the rest was built ?

yryu4526

Yes, I called make install and I did try building it manually - I already posted that previously.

But should svg have been listed in the configuration summary I posted?? It seems odd other qt components are listed but since I am not very knowledgeable I do not know if this means anything.

SGaist

What about the test logs ?

yryu4526

I have to look for them but my impression so far is that qtsvg is build but for some reason not picked up by qmake for the third-party app, nor for the test app given to me. Can I check this some way?

SGaist

All the modules should have the same structure once installed. Check the presence of files related to svg. Not only the libraries but also the cmake/qmake related ones.

yryu4526

What does "cmake/qmake related ones" mean? What exactly and where should I be looking for those files?

SGaist

cmake files in lib/cmake for exemple.

I was finally able to build the third-party application using both Qt 5.9.7 and 5.12.10. The problem I had above was due to the fact that I called the wrong qmake when building the third-party application.

I did, however have to use the flag -skip qtquick1 when building 5.9.7 and -skip qtwebengine when building 5.12.10.

I then decided to build the app using statically linked Qt-libraries using the flag -static for qmake but this has not been successful. The statically built app crashes with a segmentation fault. Note that in both scenarios I built in a docker container with the same software being installed in the container. The only difference is the -static flag.

I will create a new thread for this problem.
