How to display .dds files
Solved
General and Desktop
-
Hello
I need to display a .dds file in a GUI application (so have it in a QImage or a QPixmap or something like this. Unfortunately, .dds files are not supported since Qt 5.8.0, is there still a simple way to do it ? And if not, I read that the .dds support is commented out in the sources files, so how can I uncomment and compile only the good file without having to compile all of Qt ?
Thanks for your help and your time. -
Hi and welcome to devnet,
Are you locked to that old version of Qt ? If not, then please update to either the current version or the latest LTS.
It depends on where that code is. You can simply build only the module that contains it.
-
You need build the plugin yourself since 5.8.0.
For security reasons, the DDS handler will no longer be built by
default. Users who still want this handler can build it from the
source project.Which platform are you using?
If Windows + MinGW, run Qt command prompt from Start Menu and cd to[QtDir]\Src\qtimageformats\src\plugins\imageformats\dds.
Then runqmake, thenmingw32-make install.But you should be warned:
As it stands right now, it's severely bugged and a security minefield (crashes).
It is also pretty useless in combination with QImage: DDS files are supposed to
carry multiple individual textures, texture arrays, cubemaps; mipmap chains;
and may use specific texture compression formats. All these features are not
supported at all by QImage. -
@Bonnie when i run mingw32-make install i have this error : Qt/5.15.0/mingw81_64/include/QtCore/qdatastream.h:399 : undefined reference to `_imp___ZN11QDataStreamrsERi'
and a lot more undefined refercences, I did exactly what you said. -
@Matthieuzone Hi, I tried 5.15.0 and didn't get any error.
Can you post the full output like this? (run "qmake -v" first to show the Qt version) [ADDED] also run "mingw32-make -v" pleaseSetting up environment for Qt usage...

@Bonnie Here's the output. I have to post it in multiple times because it's too long. It looks like qmake did nothing. I don't know if it matters but I have installed Qt from the installer and not by compiling the sources.

@Matthieuzone Your qmake does not has output because you already run it, so it won't create new stash file, that doesn't matter.
But your mingw32-make output only has the link part.
Run "mingw32-make clean" first to clean the compiled files, then "mingw32-make install" again.
