Getting "unresolved externals" error while building QtCreator

  • I am building the latest QtCreator source downloaded from git, while building I get this error:

    ..\..\..\..\lib\qtcreator\plugins\qmldesigner\qtquickplugin4.dll:-1: error: LNK1120: 1 unresolved externals

    I see that many many plugins get compiled but when it reaches qmldesigner plugin the compilation stops with the above error. I also notice that the qtquickplugin4.lib get created but qtquickplugin4.dll do not!
    Some compile Output log:

  • Hi, this error has been around for some time :-(
    There might be a solution here

  • When building with Qt Creator, you have to disable the QtQuick compiler in the qmake build step. Simply unchecking the checkbox and rebuilding solved the problem.

  • @Eager This solution worked for me thanks!
