Multi-platforms building

Message 1 in thread
Hi there ;-) ,
Is there any way to build multi-platforms distros on single OS?
note:
I'm using Windows right now, and I want to build Linux distro.

Hi Muhammed,

Yes - that is possible. I do have a cygwin-based cross toolchain. Well -
my target is an uClibc based embedded linux, but it should equally work
with a glibc based cross toolchain.

Hi,
It is possible (but difficult) to do cross build between windows,linux
and macosx(using your own makefiles instead of qmake),if you use GCC
as your compiler.
For building crossplatform installation program you would need to use
something like InstallAnywhere
but you need your Qt distributions for those platform built native
first (Qt's build system doesn't support cross-build at all) (and of
course you need licenses if don't use OSS version)

For cross-platform installers it's no matter, I'm using InstallJammer
(http://www.installjammer.com/) it's wonderful installer and don't need
Java runtime (JRE) like Installanywhere

I'm escaping from installing many OS on my computer so i need a way for
building cross-platform programs without installing many OS.s

in that case your only option is setup 2 cross-chains(i assume you
host os is windows)
windows->linux-on-intel
windows->macosx-on-intel (if you want to target old macs too you will
need additional crosschain)
this IS possible(but not very easy). you will need to compile
cross-compinging version of gcc/binutils and get
arleady compiled qt for your non-native platforms(which can be got by
asking somebody with access to target platform do build for you if you
use OSS version or just ask TT for binary version if you bought
commercial versions for those platforms)
Of course qmake doesn't support this kind of build nativly (you will
need to hack around with qmakespec's or dont use qmake at all)
p.s.How you plan to debug bugs which only happen on Mac OS X for
example if you don't have Mac OS X installed? It is very possible that
some bugs manifest itself only one platform.

I give up >:o
building multi-platforms is impossible choice to me !
it's very hard and has many bugs, i think it's better to build my
project on my OS, and then publish its source code for users which want
to use them on another OS, that's it.

Or you install the other target OS on your computer (multi-boot), buy a
cheap 2nd "build computer" and install the target OS on it or use a
"virtualised" OS solution, for example have Linux run on Windows "in a
virtual box", there are several (commercial) products such as VMWare. Or
setup a SourceForge project, where others can build your source
(accessible through SVN) and contribute the binaries.
You see, no time for giving up yet ;)

FWIW, VMware is cheaper (read: free) and most of the way as fast as the
real thing.
Indeed, if you want a single computer, it almost has to be a Mac.
Installing MacOS into a VM is... messy; it can be done, but not by
any sort of officially acceptable channel.

If you are looking for a relatively cheap build computer, and you really
want to be able to build your application on the Mac, look at the Mac
Mini (http://www.apple.com). If you had one of those plus Parallels
(http://www.parallels.com/) you could have Mac/Win/Linux all installed
on the same hardware. I know your original email was asking the
question about building your application for all operating systems using
only one host operating system, so this isn't what you wanted
originally, but depending on what you are doing and what your budget is,
this might help.

Caveat emptor, YMMV, use at your own risk: I have not tried this to
build Qt itself, but I have succeeded in cross-compiling my project
this way...
I have the following fragment in my .pro file:
# Handle cross-compiler toolchains by adjusting CC, CXX, et al
!isEmpty(CROSSTOOL) {
!isEmpty(QMAKE_AR) :QMAKE_AR = $${CROSSTOOL}-$${QMAKE_AR}
!isEmpty(QMAKE_CC) :QMAKE_CC = $${CROSSTOOL}-$${QMAKE_CC}
!isEmpty(QMAKE_CXX) :QMAKE_CXX = $${CROSSTOOL}-$${QMAKE_CXX}
!isEmpty(QMAKE_LINK) :QMAKE_LINK =
$${CROSSTOOL}-$${QMAKE_LINK}
!isEmpty(QMAKE_LINK_SHLIB):QMAKE_LINK_SHLIB =
$${CROSSTOOL}-$${QMAKE_LINK_SHLIB}
!isEmpty(QMAKE_RANLIB) :QMAKE_RANLIB =
$${CROSSTOOL}-$${QMAKE_RANLIB}
}
So if I do "qmake my.pro CROSSTOOL=linux-i386", then instead of calling
gcc it will call linux-i386-gcc.
I cannot remember if there is a mechanism for setting qmake variables
at the Qt build time, but at worst, create a new mkspecs subdirectory
called something like "linux-cross-g++" (do not use "cross-linux-g++"
because of the likelihood of someone in a .pro testing for "linux-*"!)
and make it look something like this:
include(../linux-g++/qmake.conf)
CROSSTOOL=linux-i386
QMAKE_AR = $${CROSSTOOL}-$${QMAKE_AR}
QMAKE_CC = $${CROSSTOOL}-$${QMAKE_CC}
QMAKE_CXX = $${CROSSTOOL}-$${QMAKE_CXX}
QMAKE_LINK = $${CROSSTOOL}-$${QMAKE_LINK}
QMAKE_LINK_SHLIB = $${CROSSTOOL}-$${QMAKE_LINK_SHLIB}
QMAKE_RANLIB = $${CROSSTOOL}-$${QMAKE_RANLIB}
And then when you run configure, make sure to specify
"-platform linux-cross-g++" as an option.
If you try this, please post your results - I'm very curious!
And I'll second the recommendation of using crosstool, or its
successor, crosstool-ng. I'll also give you the hint that to
build as "portable" a Linux binary as possible - i.e., one that
will run on any vaguely recent Linux system - you want to use
glibc 2.3.6. I can't help you with targeting MacOS; I've never
attempted that.

Take a look at "crosstool" - http://www.kegel.com/crosstool/ and "cygwin"
- http://www.cygwin.com/- but be warned - there is a lot of trouble and
patching work involved to get a cross-linux-toolchain running under
windows. It took me ages to set it up and make it work comfortable :-(

Malte

Hi,
VMware or VirtualBox could help you. You will need to download ISO of
one of Linux distribution (or order 'free' Ubuntu via their PostIt
service)
Do you want to build distribution of Linux?Or just distribution of
your program for one or more Linux distributions?There was article in
Qt Quaterly about latter

I think this is not good choice, cuz it means that I must install
another OS on my PC to compile a new distro! this is not acceptable to
me, for example i don't have MAC OS computer !

I want to build a distro from my program to Linux & MAC too.
