Access denied when building a project

I’m working on a project with opencv lib. I use Qt 4.8 on Windows 7 and it gives me an error when building the project:

 mingw32-make.exe[1]: *** Access is denied.
 . Stop.
 mingw32-make.exe: *** [release] Error 2
 19:05:06: The process "F:\QtSDK\mingw\bin\mingw32-make.exe" exited with code 2.
 Error while building project TraySystemtry (target: Desktop)
 When executing build step 'Make'

The pro file:

    QT += xml svg core gui

CONFIG += qt

VERSION = 0.3.0

TEMPLATE = app

INCLUDEPATH += D:\OpenCV\opencv\build\include

LIBS += -LD:\OpenCV\opencv_Build\bin\

I can’t figure out the problem.

Solution

  • There are at least two possible causes:

    1. The file you're trying to build is open/used (the program is running)
    2. You don't have sufficient privileges (you don't have admin rights)

    Cause #1 is often more likely than cause #2.
