Description
I am building Qt 6.5.3 without ICU and with the WebEngine.
So, I used the -no-icu flag to deactivate ICU in non webengine module.
In the config.summary file, I can see the following report:
Qt Core: backtrace .............................. yes DoubleConversion ....................... yes Using system DoubleConversion ........ no GLib ................................... yes ICU .................................... yes Using system libb2 ..................... no Built-in copy of the MIME database ..... yes -- Build QtWebEngineQuick ............... yes Build QtPdf Modules: Build QtPdfWidgets ................... yes Build QtPdfQuick ..................... yes Optional system libraries: re2 .................................. no icu .................................. no libwebp, libwebpmux and libwebpdemux . no opus ................................. no
So, the summary tells that QtCore ICU is activated despite the use of no-icu and that the optional system library icu is not used.
And when using ldd to check if QtCore /QtWebEngine are dependent or not on ICU, I've got:
$ ldd libQt6Core.so.6.5.3 linux-vdso.so.1 (0x00007ffd77198000) libicui18n.so.60 => /lib64/libicui18n.so.60 (0x00007ffa35297000) libicuuc.so.60 => /lib64/libicuuc.so.60 (0x00007ffa34ed5000) libicudata.so.60 => /lib64/libicudata.so.60 (0x00007ffa3332b000) libdl.so.2 => /lib64/libdl.so.2 (0x00007ffa33127000) $ ldd libQt6WebEngineCore.so.6.5.3 libicui18n.so.60 => /lib64/libicui18n.so.60 (0x00007fc2ae534000) libicuuc.so.60 => /lib64/libicuuc.so.60 (0x00007fc2ae172000) libicudata.so.60 => /lib64/libicudata.so.60 (0x00007fc2ac5c8000)
I have not used the -system-webengine-icu flag so, I am surprised to see that Qt6WebEngineCore is dependent on the system ICU ...
For me, Qt6WebEngine should depend on system ICU if the -system-webengine-icu is provided at configure time.
And despite the use of the -no-icu flag, Qt6Core is still dependent too on system ICU.
So, maybe the fact that we built Qt with the Webengine activate the -icu flag by default ?
My question is: is it possible to build Qt with the WebEngine, with the ICU embedded in Qt sources ?
