How to make Makefile generate all objects in a specific dir

[Absurd]

Hi.
My project became quite big now, and I am trying to to re-organize all the source files in folders, and to keep the directory clean and organized.
So, I went from this kind of hier:

project/file0.cpp
project/file0.h
project/file1.cpp
project/file1.h
project/file2.cpp
project/file2.h
project/Makefile

To this:

project/folder0/file0.cpp
project/folder0/file0.h
project/folder1/file1.cpp
project/folder1/file1.h
project/folder1/file2.cpp
project/folder1/file2.h
project/Makefile

So I had to re-generate the Makefile using:

$ qmake-qt4 -project
$ qmake-qt4 project.pro

Now everything compiles fine, however, all the objects files are automatically generated by Makefile into my main project folder:

project/folder0/file0.cpp
project/folder0/file0.h
project/folder1/file1.cpp
project/folder1/file1.h
project/folder1/file2.cpp
project/folder1/file2.h
project/Makefile
file0.o
file1.o
file2.o
project

but I want the objects file to be automatically generated into a designated bin/ directory.
How do I force qmake-qt4 to generate a Makefile that will put all objects file in a designated directory?

• Go to you preferred output folder
• execute "qmake souce folder"
  the makefile will be created in the folder were you are. After that make -j 4
  or if you have a Ferrari try make -f 1000 :)

Hi,

Rather than forcing the output, you should rather consider out of source builds. This leaves your source tree completely clean and you can simply nuke the build folder in case of trouble.

@mrdebug but then the Makefile will be located at bin/... I want one Makefile at project/ that will put the output in bin/

@SGaist not sure I understand... what do you mean by "consider out the source builds"?

[SGaist]

That's build that don't happen in your source folder.

@Absurd said in How to make Makefile generate all objects in a specific dir:

Consider that you could have a output folder for amd64 binaries with them makefile, another folder for armhf with another makefile, Android, iOS ... everyone with a specific makefile.

@mrdebug, @SGaist ok, that makes sense...
Thanks!
