Error building for Amazon Linux 2023: QPageSetupWidget has no member named ...

[davidreedernst]

I'm trying to get wkhtmltopdf installed on Amazon Linux 2023. (We've used it on Amazon Linux 2 for years, but we're migrating to a newer virtual server). I was disappointed that the precompiled binaries page didn't have one already. But, ok, I'm trying to compile from source, even though this is outside my comfort zone. I got all of the prerequisites installed. I was pleasantly surprised (but a bit confused) that amazonlinux2023 was one of the targets in build.yaml. I eventually ran the build script as

./build package-docker amazonlinux2023-x86_64 ../wkhtmltopdf/

It did a lot of things seemingly successfully, but eventually crashed with

/src/qt/src/gui/dialogs/qpagesetupdialog_unix.cpp: In constructor 'QPageSetupWidget::QPageSetupWidget(QWidget*)': /src/qt/src/gui/dialogs/qpagesetupdialog_unix.cpp:276:12: error: 'class Ui::QPageSetupWidget' has no member named 'topMargin' 276 | widget.topMargin->setSuffix(suffix);

followed by lots of other lines citing other members that aren't present (bottom, left, & right margin; paper Width & Height; etc).

Can anyone offer any guidance on what to do from here? And/or, since the Amazon Linux 2023 OS is a recognized target, could we get a precompiled binary on that downloads page?

Thank you to anyone who can offer any help!

Please confirm that you used the 0.12.6.x branch of the main repository.

Ah, no, I didn't. I used this to get the code:

git clone --recurse-submodules https://github.com/wkhtmltopdf/wkhtmltopdf.git

but the VERSION file says that I have 0.12.7-dev. I just tried again, checking out the main repo with

git clone --recurse-submodules --branch 0.12.6 https://github.com/wkhtmltopdf/wkhtmltopdf.git

the resulting VERSION file says 0.12.6. I tried to build against that, but .... still died with the same errors. :( Other thoughts?

I meant this branch -- it should work.

[davidreedernst]

Thank you very much for your impressively quick replies! This time I did

git clone --recurse-submodules --branch 0.12.6.x https://github.com/wkhtmltopdf/wkhtmltopdf.git

and tried to build against that. I think we did get past the QPageSetupWidget errors that were the problem before. However, it still ended with an error:

compiling qrc_wkhtmltopdf.cpp

I wondered if I needed to install a package to get the QtWebKit support, but if so, I don't know what package. Also, I would have thought that this would have happened inside of the docker container, so it wouldn't depend on the library being on the build machine. Any guidance?

I'm not sure what you did, but I ran it locally and it works

I wondered if something from previous builds was mucking things up, so I ran again with

./build package-docker --clean amazonlinux2023-x86_64 ../wkhtmltopdf/

And it worked! Thank you very much for your guidance.
