How to build QtPdf?

[JoeCFD]

@slavaw you add
Qt += pdfwidgets

To find out which modules to add, you can simply check a pdf example out.
Are you making QML project?

I need to add QtPdf module to use QPdfDocument - https://doc.qt.io/qt-6/qtpdf-index.html

I make project, where QML using for view and C++ for logic. If it is important, I use qmake for build project.

I found "qt-configure-module" in this folders (path home/Qt/6.6.1/):
Which of these files should I run? Android folders for Android, GCC for Windows, WASM for C languages. Come to think of it I'm using multithreading, so I need to execute file in "wasm_multithread/bin"?

In the path "home/Qt/6.6.1/Src/qtbase/bin" i found "qt-configure-module.in" with this description inside:
I tried to exec this file and get this error:

I checked path in error and not found "qt-cmake-private", but found it in this folders:

The one you want to build for.

I get the error again:

@slavaw Did you install Emscripten? As far as I know you need it to be able to build for Wasm.

I installed Emscripten, re-executed cmd and got the last error.

@slavaw Install Ninja

[slavaw]

@jsulm said in How to build QtPdf?:

Install Ninja

I installed Ninja, tried again and got the same error.

[slavaw]

@jsulm I dug through the files and realized that my project was being built in the Src folder, but I found the "qt-configure-module" file only in "Src/qtbase/bin". I tried to execute cmd and get error.

Src folder:

Command execute:

Don't do that!
Checkout the source code again to get rid of all your build artefacts!
but I found the "qt-configure-module" file only in "Src/qtbase/bin" - this does not mean you have to build inside source forlder. As I already wrote before: use absolute path to qt-configure-module

[slavaw]

@jsulm I hope I understood you correctly, but I got an error again.

[jsulm]

@slavaw Why are you still building inside the sources?!

[slavaw]

@jsulm I tried to do as you said, along the path presented below, but it didn't help.

[jsulm]

@slavaw Why do you post pictures instead of text?
"but it didn't help" - this is not a problem description. If it did not work then please tell us what happened...

[slavaw]

@jsulm I think pictures are easier to understand, but if you insist:
I reinstalled Emscripten, after install nodejs, flex, bison, gperf and now after execute (path ~/qtpdf/build):

~/Qt/6.6.1/gcc_64/bin/qt-configure-module ../qtwebengine -- -DFEATURE_qtwebengine_build=OFF

QtPdf Module built succesfull, but CMake exited with error.

but if you insist

Well, I insist because it can be helpful for others to have it as text if they want to provide you modified versions (or test it on their own).

Regarding the error you get now: make sure you installed libxcb-xkb1 and libxcb1-dev packages.

I checked it and it is already installed.
