qt-creator

问题 Sorry if this is a dumb question, but I have already tried almost everything and am banging my head against a wall right now..

However specifying the standard version explicitly in the settings dialog is not allowed ("Option "-std=c++17" is invalid"). So, how do I tell ClangCodeModel that it should parse code as C++17? I use CMake for building the project and

问题 I have installed QtSDK in windows and its Qt library version is 4.7.0. Now i want to install Qt library version 4.8.2 for mingw and VS2008. How can i do this? How to introduce multiple versions to QtCreator? Note : I have downloaded libraries from http://qt.nokia.com/downloads 回答1: Sure you can. Just install the libraries in a different location and set Qt Creator to use those as well. You can find how here: http://doc.qt.io/qtcreator/creator-project-qmake.html. You can then choose which

问题 I've configured and built gpreftools. however, I can't seem to find the generated profile file of my program to display it. I took the following actions: Adding the -lprofiler linker flag to my .pro , building the program and the flag is added correctly at the linking stage. QMAKE_LFLAGS += -lprofiler Running with: $ CPUPROFILE=/tmp/prof.out /path/to/executable Executing: $ pprof --gv /path/to/MyExe /tmp/prof.out Then I get the following: Failed to get profile: curl -s --max-time 90 'http://

问题 On GCC 7 I have enabled most of all warnings on Qt creator 4.9. Now I have a switch statement which covers all enumeration values. If I add a default: I get a warning (from Qt creator): warning: default label in switch which covers all enumeration values If I remove the default: I get another warning (from GCC): error: this statement may fall through [-Werror=implicit-fallthrough=] } ^ error: all warnings being treated as errors What am I supposed to do? Turn off warnings? They are useful, I
