I have downloaded Qt Mobility Open source project. I had a set of demo apps. And when built it and started the App, I got this error:

Failed to start program. Path or permissions wrong?

Can someone tell me what this problem could be?

UPDATE:

The complete error is:

Starting /Users/xxxxx/Qt/qt-mobility-opensource-src-1.0.2/config.app/Contents/MacOS/config... Failed to start program. Path or permissions wrong?

I have include the ".pro" file contents:

TEMPLATE = app
TARGET = writemessage

QT += gui

include(../examples.pri)

CONFIG += mobility
MOBILITY = messaging
INCLUDEPATH += ../../src/messaging

HEADERS += 
    messagesender.h

SOURCES += 
    messagesender.cpp
    main.cpp

symbian:TARGET.CAPABILITY = NetworkServices 
    LocalServices 
    ReadUserData 
    WriteUserData 
    UserEnvironment 
    ReadDeviceData 
    WriteDeviceData

Is it Qt Creator? Does it work if launched from command line? Also it could be useful if you posted your .pro file. –  laalto Oct 14 '10 at 12:28

I did not try launching from command line. I am just learning it. I imported a sample Messaging App that came part of the open source project in to Qt creator and then I got this problem. I have updated my question with .pro file contents. –  Krishnan Oct 14 '10 at 13:00

I think the problem you are facing here are either the user rights of the executable or a wrong build path.

First, try setting the build path under 'Projects' - 'General' - Build Directory to a correct path. If that doesn't work, open the terminal, go to the build path and execute ./QtBuildProgram. If that doesn't work, take a look at the user rights (ls -a ./QtBuildProgram ), maybe the executable rights are not granted because you are running the Creator in another user mode as the terminal emulator.

Just to be sure, execute sudo chmod u+x QtBuildProgram and then execute the program from the command line by typing ./QtBuildProgram

That should also allow you to run the program from the QtCreator again.

I had the same issue in Windows. I found the answer. You need to check the "Working directory" parameter in "Run Settings" section. I changed it to the same path as my build directory and it worked.

I was running QT as admin.

In my case, it was because I have a 32-bit CPU and it was building 64-bit executables. I only figured this out after trying to run it from the command line though.

Check your run settings and see if the exe path is existing and file is built there. If you are running windows 7 or windows 8, set the qtcreator executable's settings to "Run as administrator".

点击projects，选择Run settings，点击run configuration后面的＋号；这时Excutable后面会多出一个路径，把当前工程的可执行文件路径加入，就可以执行。

如果是Linux下，你的用户对程序目录有权限吗，比如写操作的权限？
