How can I quickly import files from another project??

[User0]

Hi, good evening.
I already tried to include the absolute path of the project (plus headers and .cpp) but it doesn't work. I also tried to include files from the main.cpp file, nothing.. Could you kindly help me?

Hi and welcome to devnet,

What are you using qmake ? cmake ? Do you want to rebuild these files ?

[User0]

Hi!
Yes, I'm using qmake under Qt Creator.

Then, the second question: do you want to rebuild these files in your new project ?

[User0]

Oh, I'm sorry. Yes I want.

[SGaist]

Then the quick and dirty way to do this is:

SOURCES += /path/to/your/other/project/cpp_file.cpp
INCLUDES += /path/to/your/other/project/header_file.h

Already tried, but it was occurred an issue:

:-1: error: No rule to make target ../Library/Lib/mathfuncslib.cpp', needed by mathfuncslib.o'. Stop.

[SGaist]

Can you show your pro file ?

I'm sorry:

QT = core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

SOURCES += ~/Library/Lib/mathfuncslib.cpp
INCLUDES += ~/Library/Lib/mathfuncslib.h
SOURCES +=
main.cpp

But I get the same result..

[SGaist]

I'd rather go with an absolute path

[User0]

Unfortunately it's the same.

[SGaist]

Which version of Qt are you using ?

[User0]

5.4 version

[SGaist]

Did you re-run qmake ?

[User0]

Yes I did!!

[User0]

Ok! The path was wrong!
Now, I have to include the file in the main also? If yes, I have to use the absolute path?

You can use them as normal. You need to update INCLUDEPATH to also contain the folder where the headers are located.
