Compiling qt 5.4 for raspberry

Hello.

I'm trying to compile QT 5.4 to use cross-compile on rasp (512 mb)

My configure command:

./configure -opengl es2 -qpa eglfs -device rasp-pi -device-option CROSS_COMPILE=$BDIR/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot /mnt/rpi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -nomake tests -prefix /opt/qt5-rpi -no-pch -skip qttools


Configure finish ok:

After this i make "make -j4 finish"

While compiling the result is error:

I have tried install a lot of packages contains harfbuzz but still the same error.

Any idea?

I have the same issue. As you can see in your 'config.log', qt will use the bundled copy of harfbuzz (actually harfbuzz-ng). Yet, it seems that for some reason it doesn't compile harfbuzz-ng when one runs 'make'.
I went to qt-everywhere-opensource-src-5.4.0/qtbase/src/3rdparty/harfbuzz-ng and manually ran 'make' and harfbuzz-ng compiled. Afterwards I went back to qt-everywhere-opensource-src-5.4.0 and ran 'make' again. It got past the errors with 'harfbuzz', but my build now fails with the error:
Makefile:57: recipe for target 'sub-src-install_subtargets' failed
make[1]: *** [sub-src-install_subtargets] Error 2

It looks like you have to compile using the following sequence of commands:
$ make
$ make install

When trying directly with 'make install' my compile failed with the above mentioned 'harfbuzz' errors. Probably your 'make finish' did the same.

You also have to make sure you have correctly configured pkg-config. The error I was seeing previously was due to qt not finding dbus headers because I didn't correctly configure pkg-config.
To correctly configure pkg-config I did the following before running ./configure:
SYSROOT=/mnt/rpi-rootfs
export PKG_CONFIG_DIR=
export PKG_CONFIG_SYSROOT_DIR=$SYSROOT
export PKG_CONFIG_LIBDIR=$SYSROOT/usr/lib/arm-linux-gnueabihf/pkgconfig/:$SYSROOT/usr/share/pkgconfig:$SYSROOT/usr/lib/pkgconfig
export PKG_CONFIG_PATH=$SYSROOT/usr/lib/arm-linux-gnueabihf/pkgconfig/:$SYSROOT/usr/share/pkgconfig:$SYSROOT/usr/lib/pkgconfig

With these settings I was able to successfully build and install Qt 5.4. Hope this helps.

Oh of course, i didn't make 'make -j4 finish' , but 'make -j4 install'


After you advices, i mean:

'make
make install'

QT compiled fine.

But i have second problem with qt creator and cross compile

I add a kit, my device (raspberry), but after compile i have got a error

'Can not found a command' ( if i want to run my program on rasp)
