如何在Qt Windows中使用设置路径属性从命令行运行应用程序（.exe）时在命令行上打印日志

Question

I am using Qt 5.5.1 windows/Linux. I have a .pro file in my project folder. Inside that project folder, Qt IDE creates a .exe application file after building my project. Now as I go inside the debug folder from Command Line, I do

 set path="C:\Qt\Qt5.5.1\5.5.1\mingw48_32\bin" 

Then, I try :

START /WAIT myapplication.exe

In my project, I am using statements such as:

QDebug()<<"My logs are not getting displayed";
printf("My logs are not getting displayed");
system("Please do something");

Nothing is getting displayed on my running command line. Please help me regarding the same.

Answer 1

This line is not correct.

QDebug()<<"My logs are not getting displayed";

This should works:

qDebug()<<"My logs are not getting displayed";

And this should works but don't use it in few threads at same time:

QTextStream(stdout)<<"My logs are not getting displayed";
