Hi,
Finally we can build out and load the libqt5.so successfully, but the loading
is still very slow because too many symbols are to be relocated.
Even many of these relocated symbols are inside the libqt5.so, we suppose they
should be resolved during the link time instead of loading time.
And

Right now, the only thing which comes to mind is if you have somehow
mixed some -frtti and -fno-rtti objects.

Hi,
Now we can build out the single libqt5.so (using ARM toolchain) by:
"OPTS += -static" to create the static qt libs
"ar -x libQtXX.a" to extract the .o files
"armlink --fpic --shared *.o -o libqt5.so" to generate final single so

thanks.
I found the help information of configure missed lots of options.
It has got me perplexed.

So - are you suggesting that Qt file-system monitoring facilities
should actually generate an in-memory snapshot of the necessary
directory tree(s) for platforms that need it (in this case Mac OSX <=

I would like to explain the background of this approach.
We are now porting Qt5 (selected modules) on a low profile device
(ARM11@300MHz). All shared objects can XIP - so there is no need to load libs
from ROM to RAM. But a major problem is the loading time of an application
(qtbase examples) -
I have my doubts about how much you'll really gain from that.
This would only give you a large benefit if most applications requires all the
libs you bundle together, and that you significantly reduce the total amount of
symbols exported by the final shared library. I guess worth a quick try, bu

To reduce the loading time.

Yes, it would be very nice to include it as an add-on to Qt. We spent a

OK, this way should be easier and doable, thanks for your help ;)

No, I mean you should create a new .pro file which includes all the module libs
you want to include, and then later in that file do the tweaks needed to
generate the required result. Just compiling this new project will be enough to
produce the end result.

Or do you mean that I need create a qt5-massive-library.pro to gather all the
needed object file (.obj) from each module
instead of the static object (.a) of each module ?

QDeclarativePixmapStore (called QQuickPixmapStore in Qt5, but it's the same
code) seems to throw away cached pixmaps, every 30 seconds, even if the cache
is far from full.
This creates a performance issue when an image are being loaded during
animations, and was supposed to be in cache already.
OK, based on my current understanding, do you mean that:
I still need to build all of the current qt modules as static objects, which
can be done by OPTS += -static or by other way ?

No, you will need to link it all at once, since an .so is considered a final
product.
You might be able to mess around with a qt5-massive-library.pro, which
include()s all the module .pro files you want in the final library.
It's unknown how much tweaking you will need to achieve this final all-

Hi,
To use the static qt libraries, now I can build out all the libQtCore.a ,
libQtGui.a , libQtWidgets.a etc with option -static.
Also I can create a new shared object libQtMaster.so which is composed of all
of above static objects (libQtXXX.a),

The latest "stale" ;) Qt5 code should be what you get when you check out

Hi.
When building qt5 on OS X (10.7), the headers are not installed along the
libraries, that seems to concern all modules.
I try to build using ./build, make module-qtxxx, and make install in each
module, and in each case, I got the issue.
I configured that way : ./configure -release -opensource
