tag 834543 wontfix thanks Hi! Upstream just replied with two very detailed explanations on why this can't be fully fixed: <https://bugreports.qt.io/browse/QTCREATORBUG-20373? focusedCommentId=402638&page=com.atlassian.jira.plugin.system.issuetabpanels:comment- tabpanel#comment-402638> Eike Ziller added a comment - 7 hours ago If this is with QMake projects: This is difficult, so we don't try. The compiler setting is foremost a setting for the code model, and the project support implementations try their best to get the build system to use that compiler. QMake defines the compiler through mkspecs. Qt Creator tries to use a mkspec that is appropriate for the compiler, and afaik also adds the PATH to the location of the C++ compiler in the kit. That works as long as the compiler name is the same as one of the supported mkspecs in Qt/QMake. For CMake and Qbs projects, Qt Creator can point the build system directly to the respective compilers, so there it should work. And: <https://bugreports.qt.io/browse/QTCREATORBUG-20373? focusedCommentId=402746&page=com.atlassian.jira.plugin.system.issuetabpanels:comment- tabpanel#comment-402746> Tobias Hunger: CMake and qbs projects take the compiler settings into account. The other build systems do not: There the information set in the kit is used only to inform the build system about the compiler specific settings and the user is responsible to make sure the actual build system and Qt Creator agree on the compiler being used:-/ Qmake is in a strange in-between place: Creator will switch mkspecs passed to qmake based on the toolchain used. So switching between g++ and clang++ works – provided that the binaries are called "g+" and "clang+" and found in PATH. Unfortunately there is no reliable way to do more than that as qmake may or may not (based on the mkspec being used) ignore whatever is passed as compiler path from the outside. Recent creator versions at least warn when qmake and Qt Creator disagree on the toolchain being used. So I'm afraid I am forced to mark this bug as wontfix.
