@Arasu dirent.h usually comes with C Posix Library. Which compiler kit are you using ?
If msvc then you wont get dirent.h. Find out a way for how to include dirent.h on Windows.

Hi,

seems your projects includes some Linux/UNIX specific code.
I suggest to understand if you can refactor it in order to be ported also on Windows (for example using Qt classes)

Arasu

Thanks!

Now i am only using QT creator, none other compiler.

@Arasu I think you must start from Qt basics. Qt Creator is not a compiler but an IDE.
Please first check whether the code can be easily compiled on Windows. What are the required dependencies ? How much effort it would require for compiling ? etc..
If not easy then better to compile it on Linux as the first hitch (scandir) you came across can easliy be solved on Linux.

Hi,

Qt Creator is only a IDE, to build/run a project it uses the Kit configured for it.

Arasu

I am really sorry, i don't know these kinds of knowledge about QT Creator. Which is the compiler for both windows and linux. Let me know this for my knowledge

mcosta

Hi,

the standard compiler for Linux is gcc and there is a porting of it for Windows MinGW.
But this doesn't mean you MUST use it (you're free to choose different compiler for each platform).
In example in my company release the same product for Windows, Linux and OSX and we use different compiler

Windows (Visual Studio)
Linux (gcc)
OS X (clang)

Arasu

Thanks lot!

I will try to compile using these things.

Whether your original problem is resolved ? You had some crash issue. Also this you are facing new error now. Please post the new question rather than asking in the same question.

I can help you with both questions. Did you write simple program on linux platform with Qt creator ? Did it run ?

Hi!

Already i created one test project and ran it and working fine, but the existing project only having these issue

Arasu

Hi!

I have executable file for the project file, how can i run and open it, kindly suggest me.

mcosta

Hi,

if you have the executable you can run it from the terminal with the command

$ ./<executable_name>

You can also configure Qt Creator to run the same command.
