building from "git clone git://code.qt.io/qt/qtconnectivity.git -b 5.6" fails

[Haponov]

while trying to accomplish

  ~/raspi/qt5/bin/qmake -r

onto "git clone git://code.qt.io/qt/qtconnectivity.git -b 5.6" error is received:

       Checking for bluez... no
       Checking for bluez_le... no

and I have

pkg-config --modversion bluez
5.35

error comes from

!packagesExist($$PKGCONFIG_LIB): error("$$PKGCONFIG_LIB development package not found")

of /home/hap/raspi/qt5/mkspecs/features/link_pkgconfig.prf

all right, after doing

   export PKG_CONFIG_PATH="/usr/lib/pkgconfig"

this eeror is changed to "-lbluetooth is not found" and so is bluetooth/bluetooth.h

Happens on both x64 and x86 Ubuntu 15.10
qmake was made from git clone git://code.qt.io/qt/qtbase.git -b 5.6

Please don't tell me to create qmake from 5.5

How do I compile qtconnectivity?..

[Haponov]

does this https://dev.openwrt.org/ticket/2238 relate to problem? - I don't have bluez.pc in /usr/lib/pkgconfig/, I have it in /usr/lib/i386-linux-gnu/pkgconfig

[Haponov]

made qmake from 5.5 source. Result with it is even worse:
Checking for bluez... no
Checking for bluez_le... no
Checking for btapi10_2_1... no
Checking for libbb2... no

[Haponov]

so, after doing

1. export PKG_CONFIG_PATH="/usr/lib/x86_64-linux-gnu/pkgconfig/"
2. putting bluetooth folder (with bluetooth.h) into both qtconnectivity/config.tests/bluez and /home/hap/raspi/Qt-5.6/qtconnectivity/config.tests/bluez_le

the only problem left is

 error: cannot find -lbluetooth
 collect2: error: ld returned 1 exit status
 Makefile:64: recipe for target 'bluez' failed

let's look at

ldconfig -p | grep bluetooth
libgnome-bluetooth.so.13 (libc6,x86-64) => /usr/lib/libgnome-bluetooth.so.13
libgnome-bluetooth.so.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgnome-bluetooth.so.0
libbluetooth.so.3 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libbluetooth.so.3
libbluetooth.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libbluetooth.so

and where should I put them?..

[Haponov]

dear moderators, can this question be transferred to https://forum.qt.io/category/49/qtonpi ?

[SGaist]

Hi,

Move done

[Haponov]

solution's quite obvious - libbluetooth-dev must be installed on rpi first, then its files should be synced to

~/raspi/sysroot/usr/lib/arm-linux-gnueabihf/pkgconfig/bluez.pc

~/raspi/sysroot/usr/lib/arm-linux-gnueabihf/libbluetooth.a
~/raspi/sysroot/usr/lib/arm-linux-gnueabihf/libbluetooth.so
~/raspi/sysroot/usr/lib/arm-linux-gnueabihf/libbluetooth.so.3
~/raspi/sysroot/usr/lib/arm-linux-gnueabihf/libbluetooth.so.3.17.11

~/raspi/sysroot/usr/include/bluetooth/bluetooth.h

and then compiling qtconnectivity goes without any adventures

[SGaist]

Good !

Then since you have it building now, please mark the thread as solved using the "Topic Tool" button so that other forum users may know a solution has been found :)

[AGol]

@Haponov Could you please tell us how we can sync libbluetooth-dev to bluez.pc, libbluetooth.a , ... files?

[Haponov]

@AGol
to be clear - I was talking about http://wiki.qt.io/RaspberryPi2EGLFS

such,

1. on RPI, once you do

    sudo apt-get install libbluetooth-dev bluetooth blueman bluez libusb-dev libdbus-1-dev bluez-hcidump joystick bluez-tools
   

all the needed bluez.pc, libbluetooth.a , ... files are created on your RPI. (I've written even more installs than needed for these files, just in case)
2) do
rsync -avz pi@IP:/lib sysroot
rsync -avz pi@IP:/usr/include sysroot/usr
rsync -avz pi@IP:/usr/lib sysroot/usr
rsync -avz pi@IP:/opt/vc sysroot/opt

and then you can compile qtconnectivity on your Ubuntu PC for RPI
