Move header and source files to different location

[szumial]

Hi! I'm having an issue with restructuring my project. I would like to move the header files to a new folder named "include" and the source files to another one named "src". I have done it successfully for another project in the past, just by copy-pasting and adjusting the .pro file. However, I am not able to do it on this new project - the files are not properly recognized by Qt Creator. What steps am I missing here?

My .pro file looks like this at the moment:

TEMPLATE = lib
CONFIG += dll
DEFINES += MYNTERFACE_LIBRARY
DESTDIR = $$PWD/lib/

!contains(DEFINES, _ENABLE_QT_GUI) {
QT -= gui
} # !contains(DEFINES, _ENABLE_QT_GUI)

unix {
    target.path = /usr/lib
}
!isEmpty(target.path): INSTALLS += target

contains(DEFINES, _STATIC_BUILD) {
CONFIG -= dll
CONFIG += staticlib
} # contains(DEFINES, _STATIC_BUILD)

CONFIG += c++11

# Compiler / Linker Options 

CONFIG(debug, debug|release) {
TARGET = Mynterfaced
} else {
TARGET = MyInterface
} # CONFIG(debug, debug|release)

unix {
    target.path = /usr/lib
}
!isEmpty(target.path): INSTALLS += target

HEADERS += \
    MyInterface_global.h \
    myinterface.h \
    precompiled.h

SOURCES += \
    myinterface.cpp \

I would like the headers and sources to be located as follows:

HEADERS += \
    include/MyInterface_global.h \
    include/myinterface.h \
    include/precompiled.h

SOURCES += \
    src/myinterface.cpp \

Hi,

That looks good.

What errors do you get ?

After moving the files and adjusting the .pro, the myinterface.cpp source can't find the included header. I am getting the following messages:
error: 'myinterface.h' file not found
error: use of undeclared identifier 'MyInterface'

After changing the way I include the header in this source from:

#include "myinterface.h"

to:

#include "include/myinterface.h"

it works again. I find this strange, as previously in another project, I moved many files like this and didn't have an issue. Why is the "include/" path not recognized automatically? Am I missing somethin in the project?

Because it's a non standard path.

Yes you are, you need to add that path to the INCLUDEPATH variable.

Thank you :) That solves the case. However, I don't remember adding these non-standard paths in that previous project. Anyway, it works and the topic is closed :)

Before, your header files and source files were located in the same directory. The preprocessor searches for header files in same directory, then in directories specified using -I parameter (that is what INCLUDEPATH adds) and then in system directories.
