Re: [Gumstix-users] QT4 Embedded build question

Hi N Twerdochlib,
I did a few things to check into the Qt4 size issue. (I have not yet
used Qt4 on the Gumstix, but I plan to start learning it in the near
future, so I thought this was a good way to learn one or two things.)
First, I ran "bitbake qt4-embedded" to build all the Qt4 stuff for
Gumstix. On my quad core machine, this took around 1 hour.
Next, I went to my "${OVEROTOP}/tmp/deploy/glibc/ipk/armv7a" directory
to have a look at the new IPK files created. The Qt4 stuff, together
with MySQL, PostgreSQL, and other assorted stuff, came to 557MB. Clearly
too much for the Overo 256MB NAND.
Then I had a closer look at the IPK files actually produced. I removed
all files that had the following criteria:
* Filename contains "-dbg". It is unlikely you will be using debug
versions of libraries on the Gumstix, unless under special
circumstances.
* Filename contains "-doc". You will not need all that documentation
on your Gumstix. (For example the file
"qt4-embedded-doc_4.6.3-r25.1.6_armv7a.ipk" alone was 97MB)
* All of the "phrasebook" files.
Now the Qt4 files were still a hefty 56MB, but at least that is more
likely to fit onto your Overo. (I say "more likely" because the IPK
files are compressed, and will expand to fill up a bit more space.) But
note that that includes all kinds of libraries that Qt4 uses only if you
enable specific features. For your actual installation, you could
probably slim it down to under 10MB, after you sit down and look at what
you actually need (as Pat S. indicated earlier in the thread).
This is just my first stab at it. Probably someone with more Qt4
knowledge can suggest further ways to reduce the space requirements.
The directory
"tmp/work/armv7a-angstrom-linux-gnueabi/qt4-embedded-4.6.2-r19.1/image"
is not a good place to look to get a reasonable idea of the space
requirements. That directory will contain *everything* that Qt4 can
possibly install. However, you saw that multiple IPK files were
generated from building the qt4-embedded recipe. This is because the
various IPK files pick and choose what they install, to allow you to
customize your Qt4 installation to your requirements. I would recommend
that it is more useful to look in the "/tmp/deploy/glibc/ipk/armv7a" to
see the actual IPK file sizes.
Regards,
Markus.
