Unsolved Errors when building from source on macOS
-
Hi, I'm trying to build Qt from source on OSX El Capitan 10.11.6.
I'm running the following script:git clone git://code.qt.io/qt/qt5.git Qt5; cd Qt5; git checkout "5.10"; ./init-repository; ./configure -prefix $PWD/qtbase -opensource -no-framework -nomake tests -nomake examples; make -j4;
Unfortunately, I'm getting the following error:

Is there anything I'm doing wrong here that could be causing the issue?
Many thanks! -
Hi,
No, it seems to be a bug in Apple’s clang.
Can you update your version of Xcode ?
-
I see. Unfortunately, there are no current updates for Xcode available, as I'm running El Capitan and they require 10.12.
I was hoping that I could build Qt without frameworks as a workaround for my original issue, for which I've made a post now: https://forum.qt.io/topic/86688/debugging-qt-with-lldb-on-macos -
That has nothing to do with a no framework build.
It's the QtWebEngine module dependency that is failing to build.
So the question is: do you need the QtWebEngine module ? If not, then just don't build it.
-
The reason I mentioned a no framework build is because there seems to be an issue, which makes it difficult to debug Qt apps with frameworks on macOS unless done through QtCreator. My idea was to build both the release and debug libraries separately, so that I could get around the frameworks debug issue.
Ultimately, I'd like to build PySide2 while still being able to debug Qt.
I'm not entirely sure, but I think QtWebEngine is required to build PySide2, no?
Looking through the PySide2 docs, I couldn't find a build flag to blacklist a module (like QtWebEngine for example).
