Qt-5.2.1 cross-compile for BeagleBone with Debian 7.5
-
Regards to all!
I'm new in this group.
Forgive me if suddenly a topic already seen, but I have not found an answer at all... (it's a few months that I try!).
Is it possible to cross-compile QT5 for any version of Linux x11 with the BeagleBone?
I want cross compile Qt for develop with QtCreator and run my application on BB (now I'm trying with debian 7.5 from "here":http://elinux.org/Beagleboard:BeagleBoneBlack_Debian).
My best results is with bare-metal library downloaded from here":http://armsdr.blogspot.it/2014/03/qt-521-beaglebone-binaries.html
It works perfectly, both with example that with my test application (if compiled on BB!).Now I'm trying to cross-compile Qt on my pc with that configuration (every following "Louis McCarthy":http://armsdr.blogspot.it/2014/01/bare-metal-qt-52-on-beaglebone-black.html beautifull tutorial!):

@If I cut -sysroot ... option I've no problem in compilation, but application can work only with linuxfb platform, not under X.
With ".sysroot..." option (obviously the copy of my uSD file-system), configure give me that report:@ Configure summary

@but during "make" I get this error:
@
/usr/local/linaro/bin/../lib/gcc/arm-linux-gnueabihf/4.7.3/../../../../arm-linux-gnueabihf/bin/ld: /home/user/qt-5.2-target/debian-7.5/usr/lib/arm-linux-gnueabihf/libm.a(mpa.o): relocation R_ARM_THM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object; recompile with -fPIC
@What have I to "recompile with -fPIC" ?
I can't figure how proceed!I'm sure to be closer to my goal, but...
Thank you in advance!
