Multiple development environments: How To on Mac and Windows ?
Pages: Prev | 1 | 2 | Next
Message 1 in thread
On a Unix/Linux box, QTDIR drives everything. Change it and you can
change which Qt version you are using.
I want to do that on both a Mac and a Windows-XP machine.
How, please ?

I'm not sure what you are into here, I develop on Linux, Mac and
Windows. On Linux and Mac I simply use the qmake from the Qt-version I
like together with .pro and .pri files.
On Windows I use Visual Studio during development and make the release
binaries using qmake with again with the same .pro/.pri files.
And yes, I have four checkouts from the source repository, one for
each release (3) and for Visual Studio.

Thanks for the reply.
I think I see what you mean. I looked in the Qt source and found
various .pri files, but I can find no documentation about them.
I looked under qmake and found nothing.
"What I am into" is doing some small applications with a single
source code base that I can build on any platform with an appropriate
Qt library installed. Sounds very similar to what you are doing,
Robin. Difference being I am on a Mac, using Xcode and MinGW on a
virtual-XP.
You say, "I simply use the qmake from the Qt-version I like"
That sounds like you use a full path name (/foo/bar/Qt-version-x-dot-
y/qmake) when you invoke qmake. Is that the case ?
Any other pointers ?

Message 4 in thread
I found the answer to one question: a .pri file is a file "included"
into a .pro file. I understand it is a naming convention.
But I am still confused as to what to put in the files.
Robin, would you be willing to share an example of .pro/.pri file
contents for building on different platforms ?
Thanks.

Sure. In the .pro-file I keep all but the source references. There are
a few cases in the code where we have platform dependant code, but
those after ifed with #ifdef Q_OS_MAC, etc.
""" test.pro
TEMPLATE = app
QT += gui
...
include( test.pri )
"""
""" test.pri
HEADERS += testapp.h
SOURCES += testapp.cpp
FORMS += testapp.ui
"""
Linux:
/path/to/qmake; make
On mac I still use gcc, even though you need to install xcode, as I do
primary development on Windows
/path/to/qmake -spec macx-g++; make, however, xcodebuild would to the same trick
Windows:
c:\path\to\qmake.exe
nmake // guess you need to tweak with mingw

Check the QMake manual, you put information how to build your project.
For simpler apps you don't need anything besides telling Qt which
modules to use (via the QT variable) and what the source,header,form
files of your project are. (eventually some subdir projects).
In larger projects you might need special treatment for different
platforms, which is available with some config stuff like:
win32 : EXTRA_LIB = "winlib"
macos : EXTRA_LIB = "maclib"

you are missing the point.
I want to have an installation of Qt 4.3 and an installation of Qt
4.4 on the same machine and I want to be able to use either one at my
choice.
I know how to do this on a Linux/Unix machine. How do I do it on a
Windows Xp box with MinGW and on an Apple Macintosh using GCC/Xcode ?

This is easy on Windows. To switch Qt installations, the procedure is
exactly the same as it is on Linux. To use Qt 4.3, do this:
set QTDIR to C:\Qt\4.3.3
set PATH to %QTDIR%\bin;%PATH%
qmake
make clean
make
Now switch to Qt 4.4, do the same thing but replace "c:\Qt\4.3.3" with
the directory of your Qt 4.4 installation. Easy!

Yes, but the UI sucks. You are better off just setting it on the command
line. Each Qt installation comes with a .bat file you can run that sets
up the environment correctly for that version of Qt.

I don't think so, I specifically answered your question, what exactly to
put into .pri files (which is the same stuff that you put into .pro
files)

That has already explained, just use 2 source dirs and run the "right"
qmake in each of them.
But if you want to use the same source dir, you have to look through the
QMake manual, how to separate the output folders for files such as .o,
.moc, .h from forms, and so on. And you can probably get the Qt version
inside a qmake project file and just append it to the different output
folders so you'll get something like
src/.obj-4.4
src/.obj-4.3
src/.moc-4.4
...
Also you're going to have to change the Makefile name and append the
version number, so when you want to build you just do a make -f
Makefile.4.4 or make -f Makefile.4.3 depending on which version of Qt
you want to build with.

Why do you think this would be different on other OS'es? Thats the whole
point of using a portable buildsystem like qmake, to have the same
procedure on each platform.

With windows, if you use the Qt Integration with Visual Studio, QtDir is set
by the IDE when you switch Qt versions. This is done on a project or
solution
basis. I currently have two build sets VS2003 with Qt4.3.1 or Qt4.3.2 and
VS2005 with Qt 4.3.3.
I have no QTDIR setting in my environment variables. I just installed the
Qt versions that
I wanted with the compiler that I wanted. This seems to work fairly
well.
If you don't use the integration package, I imagine that you just set QTDIR
in
your environment. ISTR that that's what we were doing with Qt3.

That's not true anymore in Qt 4.
Even in Qt 3, QTDIR had been slowly phased out.

Does qmake just know where it is located, and then generate the
appropriate paths in its Makefiles?

In Qt4.x yes. Qt3 qmake honors the QTDIR variable.
