Qt WebEngine compilation error
Unsolved
QtWebEngine
-
I am configuring Qt commercial code from https://codereview.qt-project.org/qt/tqtc-qt5, branch = tqtc/lts-5.15.7. I need webengine and have got a pdf generation requirement for my project.
I am using the below command for configuration:

Hi,
Since you have a commercial license, you should contact the Qt Company support.
-
The fact that you are using the open source sources does not change my initial suggestion: you have a commercial license so you can request the Qt Company's help.
Do you have multiple versions of libstdc++ in your sysroot ?
On a side note, your thread title is misleading, you haven't even reached webengine yet in your build.

I have reached out to the Qt company for help. However, I have a standard license and hence it will take 1-2 days for their response. I have only one version of libstdc++ in the sysroots. I am getting the linker errors only when I added the "-webengine-printing-and-pdf" to the configure command. Without this, I was able to configure and compile Qt from source. Could you please help me what am I missing? I am doing this for the first time.
My configure command looks like this:

Before diving deeper in that stuff, you wrote that you can build Qt without issue when webengine is disabled. What about building Qt like that and then manually you try to build WebEngine and PDF ?
