What are you trying to include ? Your ‘own’ headers or Qt ?

You should add modules relevant to headers in your pro file. For example, if u are trying to include QSqlQuery , you should add QT += sql in pro file

yes my own headers which is grouped in a different folder,. I am adding that path of that folder to build environment

INCLUDE C:/Users/Desktop/Test Workspace/Sourcecode

under that sourcecode folder my header files are present.

in my file if i just include a header which is present in that particular folder its not able to fetch ,. its says no such file or directory.
however, if i give a specific path while including say

#include “..\ Test Workspace\Sourcecode\enums.h”

It gets included I do not want to do this way because it might go to an endless loop if enums.h includes someother file and that wont be able to search ..
hope you get it

Try adding SOURCE and HEADERS in Pro file.

And don’t worry about the endless loop. Includes in the ‘enums.h’ might need it to work properly.

I included that in the pro file but still of no avail,. I am not able to find the required file.
is there any specific way of including a folder of headers i have just added that in the INCLUDE in the build environments and added the headername in the pro file

Show us the contents of your .pro file, at least the INCLUDEPATH snippet.

My pro file looks like above.

By adding the INCLUDEPATH I am able to include the necessary headers required for the project
However, how should i insert an relative path there instead of

INCLUDEPATH += “C:\Users\998234\Desktop\Custom Workspace\Custom Workspace\Customapp\Sourcecode”

since I am new to scripting or the makefiles, I want to know where i can find the macros to be used like

$$qtLibraryTarget or $$[QT_INSTALL_PLUGINS]

from there i can specify the path to the required folders

AFAIK, you should add here in headers and sources ,ie along with

Yes, thanks for it. I am able to include the headers now , but was only looking at the way of giving a relative path, instead of using a absolute path as i am doing in the INCLUDEPATH macro is there a way of providing that using some environment variables or something

Relative path should also work. And i don’t know much about env vars :( Perhaps you’ll find here [developer.qt.nokia.com] or there [developer.qt.nokia.com] .Research. :)
