Cannot reproduce. If it still has been reproducing — most likely it's solved by fixing https://bugs.gentoo.org/919714
Created attachment 895242 [details] ninja failure of libcamera build Build failure when building libcamera manually (no ebuild for it yet). /usr/include/qt5/QtGui/qtgui-config.h:26: error: "QT_NO_IMAGEFORMAT_JPEG" redefined ... 26 | #define QT_NO_IMAGEFORMAT_JPEG true /usr/include/qt5/Gentoo/gentoo-qconfig.h:8: note: this is the location of the previous definition 8 | #define QT_NO_IMAGEFORMAT_JPEG So should Gentoo/gentoo-qconfig.h define it something, like "true"? Because that does fix it...

https://bugs.gentoo.org/919714 (the error is now just a warning): /usr/include/qt5/QtGui/qtgui-config.h:26: warning: "QT_NO_IMAGEFORMAT_JPEG" redefined 26 | #define QT_NO_IMAGEFORMAT_JPEG true | In file included from /usr/include/qt5/QtCore/qconfig.h:1, from /usr/include/qt5/QtCore/qglobal.h:66, from /usr/include/qt5/QtCore/qatomic.h:41, from /usr/include/qt5/QtCore/qvariant.h:43, from /usr/include/qt5/QtCore/QVariant:1, from ./ui_DeviceWidget.h:12: /usr/include/qt5/Gentoo/gentoo-qconfig.h:8: note: this is the location of the previous definition 8 | #define QT_NO_IMAGEFORMAT_JPEG | However, is this the right way to fix it? Are there going to be more packages that get hit with this, and we'll patch each of them as we go? Or is there something more systemically-wrong with gentoo-qconfig.h: #define QT_CUPS #define QT_DBUS #define QT_FREETYPE #define QT_IMAGEFORMAT_PNG #define QT_LIBINPUT #define QT_LINKED_OPENSSL true #define QT_NO_ACCESSIBILITY_ATSPI_BRIDGE #define QT_NO_IMAGEFORMAT_JPEG #define QT_NO_OPENGL_ES #define QT_NO_OPENGL_ES_2 #define QT_OPENGL #define QT_OPENSSL #define QT_SSL #define QT_WIDGETS Does it bother anyone that these are being defined to <"empty"> values? Is that really correct? If that is true, then I would at least wrap each #define in an "#ifndef ..." just to be safe. Not sure if there is a root-cause here yet...
I dug into the Qt5 includes a little more, and the only solution that comes to mind that appears reasonably doable (because gentoo already appears to do it elsewhere) is to special-case the /usr/include/qt5/Gentoo/gentoo-qconfig.h:8:#define QT_NO_IMAGEFORMAT_JPEG setting as /usr/include/qt5/Gentoo/gentoo-qconfig.h:8:#define QT_NO_IMAGEFORMAT_JPEG true just like it is already being done for: #define QT_LINKED_OPENSSL true also in /usr/include/qt5/Gentoo/gentoo-qconfig.h, which seems to overcome a very similar issue in: /usr/include/qt5/QtNetwork/qtnetwork-config.h:6:#define QT_LINKED_OPENSSL true So wherever this /usr/include/qt5/Gentoo/gentoo-qconfig.h originates/is-generated, treat the QT_NO_IMAGEFORMAT_JPEG #define the same as QT_LINKED_OPENSSL and don't let the "#define..." stay empty (though that is technically legal), give it a "true" value just to avoid this issue system-wide rather than have to fix the -pedantic error/warning compiler flags on each package that hits this issue. At least that's the theory...I haven't confirmed because I didn't track-down the origins of /usr/include/qt5/Gentoo/gentoo-qconfig.h, but I think that at least makes sense. Either way, patching the /usr/include/qt5/Gentoo/gentoo-qconfig.h file is likely the solution like I mention in comment 3, but where best to put it...gentoo maintainers get to make that call. Just trying to help...
