Ok, I made some progress in trying to build Qt5 for ARM (it's actually the iMX53 from Freescale). I am using the toolchain and some libraries of freescale, that they provide with LTIB (linux target image builder).
And I am using a modified qmake.conf in mkspecs (linux-g++-mx5x).
The problem right now is that some libraries aren't found. Some of them do excist and some not. These are the missing libs, with the location where I found them by myself:
tiffio.h (found in /home/qt5/qtbase/src/3rdparty/libtiff)
libmng.h (found in /home/qt5/qtbase/src/3rdparty/libmng)
ibase.h (found in /home/qt5/qtbase/include/QtSql)
oci.h (found in /home/qt5/qtbase/include/QtSql)
sql.h (found in /home/qt5/qtbase/include/QtSql)
sqlite.h (found in /home/qt5/qtbase/include/QtSql)
unicode/utypes.h (found in /usr/include/unicode)
unicode/ucol.h (found in /usr/include/unicode)
unicode/ustring.h (found in /usr/include/unicode)
Additionaly the arm-none-linux-gnueabi-g++ compiler does not recognize the following arguments:
That's a part of the output of the building process (look the attached output of the configure command, to view all of the error messages):
/opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/bin/arm-none-linux-gnueabi-g++ -c -pipe -mmmx -g -Wall -W -I../../../mkspecs/linux-g++-mx5x -I. -I/home/lucid/imx/11.09/ltib/rootfs/usr/include -I/home/lucid/imx/11.09/ltib/rootfs/usr/include/glib-2.0 -I/tftpboot/ltib/usr/lib/glib-2.0/include -I/tftpboot/ltib/usr/include/gstreamer-0.10 -I/tftpboot/ltib/usr/include/libxml2 -I/home/lucid/imx/11.09/ltib/rootfs/usr/include/freetype2 -I/home/lucid/imx/11.09/ltib/rootfs/usr/include/mysql -I/opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/lib/gcc/arm-fsl-linux-gnueabi/4.4.4/include -o mmx.o mmx.cpp
cc1plus: error: unrecognized command line option "-mmmx"
make: *** [mmx.o] Error 1
I tried to do it like this:
QMAKE_LFLAGS_RPATH = -Wl,-rpath,
QMAKE_RPATHDIR += "/tftpboot/ltib/usr/lib"
QMAKE_RPATHDIR += "/tftpboot/ltib/usr/local/lib"
QMAKE_RPATHDIR += "/tftpboot/ltib/lib"
but this approach didn't work.
Does anyone know how to include the correct paths into the qmake.conf?
