I used to think it's gcc/qt version's problem, but after I upgrade gcc/qt, it still don't work.

gcc version 5.5.0 20171010 (Ubuntu 5.5.0-12ubuntu1~14.04)
Using Qt version 5.9.1 in /opt/Qt5.9.1/5.9.1/gcc_64/lib

I don't know what I can do now to make it work.

Hi @zezhou

Please, try to replace Q_DECLARE_FLAGS(Buttons, Button) at profiler_gui/window_header.h:86 with using Buttons = QFlags<Button>;. If this error still occur, try to add #include <QObject> (or even #include <qobjectdefs.h>) in the same file.

[zezhou]

@cas4ey Thanks. It solve the problem, but there still have other compile fails.

[cas4ey]

@zezhou do you mean that replacing of Q_DECLARE_FLAGS helped // or including additional header ? Which one?

It would be great if you will create a pull request with fixes (or at least post them here).

[cas4ey]

but there still have other compile fails.

Which ones?

try to replace Q_DECLARE_FLAGS(Buttons, Button) at profiler_gui/window_header.h:86 with using Buttons = QFlags<Button>;

I try this solution, and it stop at another position:

easy_profiler/profiler_gui/blocks_graphics_view.cpp:80:26: fatal error: QSignalBlocker: No such file or directory
compilation terminated.
make[2]: *** [profiler_gui/CMakeFiles/profiler_gui.dir/blocks_graphics_view.cpp.o] Error 1

I think it may be the qt version confliction, though I upgrade qt to 5.9.1.

[cas4ey]

Do you have Qt less than v5.3 installed at the same time?
I think you might not set up all environment variables properly after upgrade to 5.9.1.
Try cmake -DCMAKE_PREFIX_PATH="<your-path-to-Qt>/lib/cmake"
For example, cmake -DCMAKE_PREFIX_PATH="/opt/Qt5.9.1/5.9.1/gcc_64/lib/cmake" ..

[zezhou]

I try this

cmake -DCMAKE_BUILD_TYPE="Release" -DCMAKE_PREFIX_PATH="/opt/Qt5.9.1/5.9.1/gcc_64/lib/cmake" ..

and build success. thanks a lot.
