Qt resource not showing up in static build...

mrjj

Also to be clear.
It does work in statically linked debug version but not in a
statically linked release version?
That is odd.
When you made your statically linkable Qt, you did use release mode?

mzimmers

@mrjj yes, I tried other formats...they looked terrible so I went to .svg.

@kshegunov: project file layout is entirely flat...do I need a subdirectory called /logos?

mzimmers

@mrjj not quite: it works in dynamic/debug, but not in static/release. I haven't tried the other permutations yet.

kshegunov

Aha! So your debug is in fact dynamically linked. Then do the manual resource initialization as @SGaist hinted!

mzimmers

@kshegunov sorry - I thought I'd made that clear in my OP.

I've added this line to my main (my resource file is called "resources.qrc"):

    Q_INIT_RESOURCE(resources);

Still doesn't show, and I'm getting that null pixmap error.

SGaist

Do you have several resources named like that ?

mzimmers

@SGaist I'm not sure what you mean by "named like that," but I only have one .qrc file, and it only has two files in it.

kshegunov

Okay, can you grab a screenshot from the resource editor? Unless that path is an alias, then you need to put the image into that folder under the project. I personally always alias the things because it feels quite clumsy otherwise ...

mzimmers

So I need a subdirectory in my source folder? I'll try that.

EDIT: just moved logo to a subfolder, rebuilt and now I'm getting an error:

[release/qrc_resources.cpp] Error 1

So I deleted the moved file and re-added it. Still getting the null pixmap error.

kshegunov

@mzimmers said in Qt resource not showing up in static build...:

just moved logo to a subfolder, rebuilt and now I'm getting an error:

Not any subfolder, looking at the screenshot you need a folder called logos under your project root. Then readd the file and I think it should work.

mzimmers

@kshegunov no joy.

EDIT: put some text in here to separate the pics.

But at least now it's missing from both the debug and release versions...

kshegunov

But now your resource tree looks funny, you have two folders named "logos" there ...?

mzimmers

OK, I obviously don't know what's going on here. The resource editor requires me to add a prefix before I can add a file. When I add the file, if it's in a subdirectory, that gets prepended to the file name. This is why you're seeing what appears to be two levels of folders.

I don't know how to do this differently.

kshegunov

Ah, okay. That's why I'm saying it's damn clumsy. Add only a / as prefix and then add your file. It should fix the double folder thing.

mzimmers

@kshegunov alas, that didn't work, either. You're right, though...this is one awkward interface.

kshegunov

You mean it didn't fix the double folder thing or you still can't load the image?

Your resource file should look something like this:

Then you'd load with :/images/20171022_152431.jpg.

mzimmers

Yes my resource file looks similar to yours. The image displays when dynamically built, but not static.

kshegunov

Could you try with a static/debug just for the sake of it, to be honest I'm at a lost as you seem to have done everything right.

mzimmers

Static/debug doesn't display the image, either. So I'm doing something wrong with the inclusion of resources into a static build...?

kshegunov

Yes, this would be my best guess. Could you look inside the build folder and see if there's a file .rcc named after your qrc file? Perhaps it's not linked with the binary for some reason ...
