Last time I looked for QT5 was some weeks ago.
Thanks a lot for the pointer !

First, instead of fixing the configure script, I figured I could pass
"-no-use-gold-linker"
to configure, that worked just as well.

Could you elaborate as to how "Qt 5.3 is [...] implemented different than
the current 
mainline Qt 5.4."?

Not an option as PTXdist 2015.05 (current version) does not feature Qt 5.4 ...
Besides, why migrate and risk errors? 
I just want to upgrade Qt - I should be able to just drop-in the qt5.* rules
files, right?
Of course while doing so I should update dependencies as needed.


> - the you can remove the qt5 related rules from BSP

Which is exactly what I did:
- ran menuconfig to deselect Qt 5.3
- replaced the Qt 5.3 rules with the Qt 5.4 rules
- ran menuconfig to select Qt 5.4 (and options ...)


> - adopt Qt 5.4 mkspecs to find the correct EGL stuff

Is this the right way? 
The configure script is told to use pkgconfig - Just getting the *.pc files
in the right spot
should be enough (and of course making sure all paths within those .pc files
are correct ...).
As a bonus, all other packages that use pkgconfig should work as well.


> - Feel free to contact TQ systems support

Judging from your email address, TQ systems is already aware of this!

git://git.pengutronix.de/git/ptxdist.git

That is the meaning of "mainline".

Qt 5.3 is in our BSP which is implemented different than the current mainline Qt 5.4.
Mixing things is not expected to work.

You can do 

- ptxdist migrate to bring the BSP to the current PTXdist version
- the you can remove the qt5 related rules from BSP
- reconfigure to build with Qt 5.4 from mainline PTXdist
- adopt Qt 5.4 mkspecs to find the correct EGL stuff
- Feel free to contact TQ systems support


Note: when migrating to a new ptxdist version, you need to build from scratch.

* [ptxdist] Sysroots and pkg-config (Qt 5.4.2)

Hi,

I am using PTXdist 2014.11.0 and a BSP provided by TQ for a Freescale i.MX6q
CPU.
This CPU has binary-only drivers for Open-GL/ES.

I downloaded just the new qt5.in/.make as well as all patches and custom
qmake-spec 
for Qt 5.4.2 and I am trying to get it to compile using the Freescale
(VIVANTE) egl 
drivers.

The drivers install some samples to /opt as well as libs to /usr/lib and
matching 
headers to /usr/include.
The default rule file was to just package everything together and install it
on the 
target. This was enough to verify that the GPU is working.

Which sysroot is the right one? sysroot-host seems like the right choice. I can 
add pkgconfig files to sysroot-host/lib/pkgconfig (e.g. egl.pc) and these
seem to 
work as expected.

Building Qt is a totally different beast ...
I had to add a patch to the configure script to disable the gold linker 
"CFG_USE_GOLD_LINKER=no". Turns out configure is using sysroot-cross ...
sysroot-cross has a wierd pkg-config (arm-v7a-linux-gnueabihf-pkg-config in my 
case) which does not seem to work:

      $> ./p bash
      [ptx] $> which pkg-config
      ..../platform-dzm/sysroot-host/bin/pkg-config
      [ptx] $> ./platform-dzm/sysroot-cross/bin/pkg-config --debug --list-all

Now I get a list of all packages from my Ubuntu 14.04 ... 
(and maybe some embedded ones as well). So I tried "fixing" this setup by
calling
the right pkg-config by updating the first few line like:

       #PKG_CONFIG="${PKG_CONFIG_ARRAY[1]}"
       PKG_CONFIG="../../sysroot-host/bin/pkg-config"

But lets keep moving here - pkg-config rules for egl are in place (I took them
from Yocto's meta-fsl-arm layer) and configure continues past the EGL checks.
However now I'm stuck with an error about d-bus.
dbus-1.8.8 is compiled and installed using the default rules. But the pkg-config
rule file is not installed (again: which sysroot?) - why?

The next obvious question would be: what else is "missing"? and why?
Or were there some bugfixes between PTXdist 2014.11.0 and the latest that affect
pkg-config or any library install?

A lot of the things I did *feel* wrong. I would assume that PTXdist should
do these
for me - e.g. make sure pkg-config is updated with every library.
Also, sysroot-target seems like the most obvious "sysroot" choice since the
documentation
for PTXdist specifically mentions  "sysroot-target : Contains everything
target architecture
dependend (libraries, header files and so on)." but this one is not used at all.

One last thing: Is the gold linker used in newer versions of PTXdist?

How do I continue building the latest Qt library?
