Cross compile errors: Qt 4.8 libs for arm with phonon using marvell tool chain

I have installed qt-everywhere-opensource-src-4.8.0. Under mkspecs/qws/, I created a new directory for marvell:

linux-arm-marvell-linux-gnueabi-g++ and modified the qmake.conf as follows:

QMAKE_CC = arm-marvell-linux-gnueabi-gcc
QMAKE_CXX = arm-marvell-linux-gnueabi-g++
QMAKE_LINK = arm-marvell-linux-gnueabi-g++
QMAKE_LINK_SHLIB = arm-marvell-linux-gnueabi-g++

QMAKE_AR = arm-marvell-linux-gnueabi-ar cqs
QMAKE_OBJCOPY = arm-marvell-linux-gnueabi-objcopy
QMAKE_STRIP = arm-marvell-linux-gnueabi-strip

This is for a Marvell ARMADA 168 platform.

My configure script is as follows:

Glib support cannot be enabled due to functionality tests!
Turn on verbose messaging (-v) to ./configure to see the final report.
If you believe this message is in error you may use the continue
switch (-continue) to ./configure to continue.
-------------------------------------

Not sure why "Glib support cannot be enabled due to functionality tests"? Any help is appreciated.

Thanks much!

Re: Cross compile errors: Qt 4.8 libs for arm with phonon using marvell tool chain

I made further progress by providing the path to glib.h and other headers. I had to add library search path for the pre-built libraries provided by Marvell. These were under marvell toolchain. The modified configure arguments are as follows:

-----------------------------------

./configure -v -embedded arm -little-endian \
-no-fast -no-largefile -no-accessibility \
-xplatform qws/linux-arm-marvell-linux-gnueabi-g++ \

------------------------

It compiled most of the Qt libraries, now it tries to compile JavaScriptCore as part of WebKit and running into compilation problems. Any ideas on how to fix this?

Re: Cross compile errors: Qt 4.8 libs for arm with phonon using marvell tool chain

I tried to work-around these errors, but got into some other errors...

So, I removed qt-webkit from the configure command and now, all the libraries are building fine. I had to fix one thing as explained in the fix here:

https://bugreports.qt-project.org/br...s:all-tabpanel

I need to re-visit qt-webkit later. Or may be build all the libraries using an older version of Qt Libs, say, 4.7.3....

Added after 7 minutes:

Just a note that if you use the configure script provided above, it will fail when building moc, uic, rcc tools. The -l options provided in configure script apply to all Makefiles, so they get into Makefiles that don't need them as well. Just edit the Makefiles in these tool directories: src/tools/<moc,uic,rcc>/Makefile and remove the -l libraries from LIBS macro.
