Missing binary operator before token "("
-
Alt-title: a series of unfortunate events.
Hello, I'm new here, please be gentle with the programming vernacular.
Info:
Linux, ubuntu 18.04
Qt version 5.13.0
now: Qt-5.12.0
Qt creator version: 4.9.3(not sure, uninstalled this)
now: Qt creator version 4.8.0
Qmake 3.1Basically, I wrote a program using qt creator. The kit I used was autodetected: "Desktop Qt 5.13.0 GCC 64bit"
On trying to release my program, I searched for ways to convert it into an appimage. I came across "linuxdeployqt". However, linuxdeployqt could not find Qt-5.13.0. I will not go into detail, but I decided to port my program to Qt5.12.0.
I downloaded 5.12.0's online installer. After installing, the auto-detected kit "Desktop Qt 5.12.0 GCC 64bit" popped up in my kit manager. So I reconfigured my project to run on that kit, and I was met with 700+ error messages, of which a large portion were 'Missing binary operator before token "("'
https://forum.qt.io/topic/27925/solved-qt_deprecated_since-gives-error-missing-binary-operator-before-token-in-qnamespace-h
This forum does not help me, because I tried starting a new project in qt creator:
file->new file/project->application->qt quick application - empty
And the same issue occured. The problem identified in the forum was that a header file name conflicted with some other system stuff. This would be impossible on a fresh project with nothing in it(and no header files, for that matter)https://stackoverflow.com/questions/21338385/what-does-the-compiler-error-missing-binary-operator-before-token-mean
This doesn't help me either. Something to do with incorrect syntax in preprocessor commands. Doesn't help me, I've never even touched that stuff.I tried uninstalling qt5.13 and 5.12 using the maintenance tool for each. Upon reinstalling qt5.12 using the online installer, and starting a fresh project, the same error occurs.
I checked my kit manager, and confirmed that the kit was using qmake located in my installed qt5.12.0/5.12.0/lib/ folder.
I don't really know whats going wrong, I'm guessing it isn't related to my own program, since fresh projects have the same problem. Any help appreciated
Fresh project I created to test:
"qt12test"
-qt12test.pro
-qt12test.pro.user
-main.cpp
-main.qml
-qml.qrcError message I got from running this fresh project using Qt5.12.0 kit:

I don't have an answer for you, but looking at your SO reference page it seems awfully like what is reported in https://stackoverflow.com/a/53566303/489865 ?Do you have your own source file named
features.h? Can you make your compilation show the commands it is issuing, do you use thegcc's -Ioption?
