[Solved]Compile Qt with tslib
-
Hi and welcome to devnet,
You should run configure with -verbose.
This way you should see the exact error you are encountering
-
This is the error in verbose mode:
@/home/dominik/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++ -c -pipe -marm -mfpu=vfp -mtune=arm1176jzf-s -march=armv6zk -mabi=aapcs-linux -mfloat-abi=hard --sysroot=/mnt/rasp-pi-rootfs -O2 -Wall -W -fPIE -I../../../mkspecs/devices/linux-rasp-pi-g++ -I. -o tslib.o tslib.cpp
tslib.cpp:42:19: fatal error: tslib.h: No such file or directory
compilation terminated.
make: *** [tslib.o] Error 1
tslib disabled.
The tslib functionality test failed!
@Ok he don't find the tslib.h, but it is in the folder which I give to qmake:
@dominik@Linux-Dominik ~/opt/qt5/qtbase $ ls /home/dominik/opt/tslib/build/include
tslib.h
@I don't get it...
-
Then you should rather add
@-L /home/dominik/opt/tslib/build/lib -I /home/dominik/opt/tslib/build/include@
To your configure command
-
Hmm, okay, sorry I thought that it is enough when I write this to qmake.conf.
Now this error occurs:
@/home/dominik/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++ -Wl,-rpath-link,/mnt/rasp-pi-rootfs/opt/vc/lib -Wl,-rpath-link,/mnt/rasp-pi-rootfs/usr/lib/arm-linux-gnueabihf -Wl,-rpath-link,/mnt/rasp-pi-rootfs/lib/arm-linux-gnueabihf --sysroot=/mnt/rasp-pi-rootfs -Wl,-O1 -o tslib tslib.o --sysroot=/mnt/rasp-pi-rootfs -L/home/dominik/opt/tslib/build/lib -lts
/home/dominik/opt/tslib/build/lib/libts.so: file not recognized: File format not recognized

@ -
Then tslib is probably not built for ARM
call
@file /home/dominik/opt/tslib/build/lib/libts.so @
To see what kind of file it is
-
It's a symbolic link to this file and the output is this:
@dominik@Linux-Dominik ~/opt/qt5/qtbase $ file /home/dominik/opt/tslib/build/lib/libts-1.0.so.0.0.0
/home/dominik/opt/tslib/build/lib/libts-1.0.so.0.0.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=0x775054f586db43f31d8b8dd1b7ae2738b20e8923, not stripped
@I see that the architecture is wrong... I will try to rebuild this. At the configure command of tslib is there also a cross compile parameter? Or should the --host=arm-linux be enough?
-
You might also need to tell the configuration script that your are using arm-linux-gcc (adapt the name to your cross-compiler)
-
Ok thank you! Now it works! I have used this statement for compiling tslib:
@./configure CC=/home/dominik/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc CXX=/home/dominik/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++ -host=arm-none-linux-gnueabi target=arm-none-linux-gnueabi -enable-static=yes -enable-shared=yes -prefix=/home/dominik/opt/tslib/build/@
-
You're welcome !
Now that you have tslib working, please update the thread title prepending [solved] so other forum users may know a solution has been found :)
