[Thiago Macieira told me to move my Qt + TSAN diskussion from Interest mailinglist over here]
my System is a freshly installed Ubuntu 22.04, all updates background: im currently testing a green-field 400kLOC project with ASAN and TSAN (in the future with MSAN) there is some sort of simple communication server holding all my stuff together which is based on Qt and this server is giving me some TSAN warnings from Qt code - i've compiled all relevant third parties which Qt is using and Qt and my server itself with TSAN (in my case only GLib and DBus) to get rid of false-positives later i will try to ASAN/TSAN test a very organic grown Qt5->Qt6 port of a ~1Mio LOC project and hope to get rid of the most basic ASAN/TSAN findings before - at least with Qt dev branch so the next upcoming releases are cleaner for my testing currently a simple QApplication program throwing a good amount of TSAN warnings on start/exit and i've got some other simple Qt unit-tests that contains more warnings the hard part (for me) was first to build all the relevant dependecies with TSAN Glib was easy to build and integrate into the Qt build - build-instructions + PKG_CONFIG_PATH with qt cmake = works Qt cmake is directly detecting my installed Glib-build DBus 1.12.20 took some dicussions to build (the lastest 1.15 is equaly built like Glib) but DBus does not integrate as clean as GLib with PKG_CONFIG_PATH - i think that is related to this bug https://bugreports.qt.io/browse/QTBUG-86283 so my first question is: how can i make cmake use my own build DBus lib like cmake did with Glib? so these are my build steps with the resulting TSAN warnings at end ( Thiago Macieira will take a look in the coming days) mkdir ~/qt6_dev 1. build Glib with TSAN cd ~/qt6_dev git clone https://gitlab.gnome.org/GNOME/glib.git cd glib git checkout 2.72.1 cd .. mkdir glib-build cd glib-build meson setup ../glib -Dbuildtype=debug -Db_sanitize=thread --prefix ~/qt6_dev/glib-install meson compile meson install 2. build DBus with TSAN (and TSAN-Glib) git clone https://github.com/freedesktop/dbus.git cd dbus git checkout dbus-1.12.20 cd .. mkdir dbus-build cd dbus-build PKG_CONFIG_PATH=~/qt6_dev/glib-install/lib/x86_64-linux-gnu/pkgconfig cmake ../dbus/cmake -DCMAKE_INSTALL_PREFIX=~/qt6_dev/dbus-install -DCMAKE_CXX_FLAGS="-g -fno-omit-frame-pointer -fsanitize=thread" -DCMAKE_C_FLAGS="-g -fno-omit-frame-pointer -fsanitize=thread" -DCMAKE_EXE_LINKER_FLAGS="-fno-omit-frame-pointer -fsanitize=thread" -DCMAKE_MODULE_LINKER_FLAGS="-fno-omit-frame-pointer -fsanitize=thread" cmake --build . --parallel 6 cmake --install . 3. build Qt 6.4(with patch: https://codereview.qt-project.org/c/qt/qtbase/+/442720 - my first ASAN finding) with TSAN cd ~/qt6_dev git clone git://code.qt.io/qt/qt5.git qt6 cd qt6 perl init-repository git checkout v6.4.0 # apply patch cd .. mkdir qt6-build cd qt6-build PKG_CONFIG_PATH=~/qt6_dev/glib-install/lib/x86_64-linux-gnu/pkgconfig:~/qt6_dev/dbus-install/lib/pkgconfig ../qt6/qtbase/configure -debug -opensource -nomake examples -nomake tests -sanitize thread -prefix ~/qt6_dev/qt6-install cmake --build . --parallel 6 cmake --install . problem: qt6 cmake ignores for unknown reasons my TSAN dbus lib so we later use LD_LIBRARY_PATH to force TSAN dbus lib loading 4. build simple example qt_tsan_tests with TSAN int main( int argc, char* argv[] ) { QApplication app( argc, argv ); QWidget window; window.resize( 320, 240 ); window.show(); return app.exec(); } 5. start example with LD_LIBRARY_PATH=~/qt6_dev/dbus-install/lib:$LD_LIBRARY_PATH ./qt_tsan_tests 6.
