[Interest] How to inspect a Qt Application memory usage?

[Nuno Santos]

Rene,

I have the same problem with valgrind on Mac OSX:

16:20:22: valgrind --child-silent-after-fork=yes --xml-socket=127.0.0.1:51397 --log-socket=127.0.0.1:51398 --xml=yes --smc-check=stack --tool=memcheck --gen-suppressions=all --track-origins=yes --leak-check=summary --num-callers=25 --dsymutil=yes /tmp/build-xpto-Desktop_Qt_5_10_0_clang_64bit-Debug/XPTO.app/Contents/MacOS/XPTO
16:20:22: Failed to start program. Path or permissions wrong?
16:20:22: Analyzing finished.

Francisco, any suggestions?

Thanks!

Regards,

Nuno
