QT base compiling error
-
Hi,
I have used the instructions in link below for cross compile QT creator. While qt base compiling, i got the errors below after "make -j 4":http://wiki.qt.io/RaspberryPi_Beginners_Guide
collect2: error: ld returned 1 exit status Makefile:680: recipe for target '../../lib/libQt5Core.so.5.0.2' failed make[2]: *** [../../lib/libQt5Core.so.5.0.2] Error 1 make[2]: Leaving directory '/home/eray/Raspberry/qt-everywhere-opensource-src-5.0.2/qtbase/src/corelib' Makefile:75: recipe for target 'sub-corelib-make_first' failed make[1]: *** [sub-corelib-make_first] Error 2 make[1]: Leaving directory '/home/eray/Raspberry/qt-everywhere-opensource-src-5.0.2/qtbase/src' Makefile:40: recipe for target 'sub-src-make_first' failed make: *** [sub-src-make_first] Error 2What can i do for solving this problem?

Hello,
When did you pull from the repository? I was not able to build it with the last commit as well. I guess some patience is advised until they fix up the problem. Is there any specific reason you want Qt 5.6, since it's not really released yet?Kind regards.

As mentioned there, ( "As gitorious is offline I used the following path instead: https://github.com/shahriman/cross-compile-tools.git") i have pulled from the link they have given : https://github.com/shahriman/cross-compile-tools.git
By the way, sorry for wrong output, because i have tried somethings about building it so, the error output is below:
collect2: error: ld returned 1 exit status Makefile:680: recipe for target '../../lib/libQt5Core.so.5.0.2' failed make[2]: *** [../../lib/libQt5Core.so.5.0.2] Error 1 make[2]: Leaving directory '/home/eray/Raspberry/qt-everywhere-opensource-src-5.0.2/qtbase/src/corelib' Makefile:75: recipe for target 'sub-corelib-make_first' failed make[1]: *** [sub-corelib-make_first] Error 2 make[1]: Leaving directory '/home/eray/Raspberry/qt-everywhere-opensource-src-5.0.2/qtbase/src' Makefile:40: recipe for target 'sub-src-make_first' failed make: *** [sub-src-make_first] Error 2 -

You seem to have problems with compiling Qt, but you've not given the exact error in the make output, why not download a precompiled binary and take it from there? Here's a guide I was able to find on a site for the raspberry. If you still want to compile Qt use one of the official repositories and you can look up this guide or this one. If you want to try and diagnose why Qt is not building, go up in your make output and find the exact error (either the compiler or linker should be complaining somewhere), usually the problem is an unmet dependency.Kind regards.

I will try the links that you have given and the exact error in the make output :.obj/release-shared/qlibrary_unix.o: In function `QLibraryPrivate::load_sys()': qlibrary_unix.cpp:(.text+0x1230): warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /mnt/raspberry-rootfs/usr/lib/arm-linux-gnueabihf/libdl.a(dlopen.o): In function `dlopen': (.text+0xc): undefined reference to `__dlopen' /mnt/raspberry-rootfs/usr/lib/arm-linux-gnueabihf/libdl.a(dlclose.o): In function `dlclose': (.text+0x0): undefined reference to `__dlclose' /mnt/raspberry-rootfs/usr/lib/arm-linux-gnueabihf/libdl.a(dlsym.o): In function `dlsym': (.text+0xc): undefined reference to `__dlsym' /mnt/raspberry-rootfs/usr/lib/arm-linux-gnueabihf/libdl.a(dlerror.o): In function `dlerror': (.text+0x0): undefined reference to `__dlerror' /mnt/raspberry-rootfs/usr/lib/arm-linux-gnueabihf/libm.a(feholdexcpt.o): In function `feholdexcept': (.text+0x48): undefined reference to `_dl_hwcap' /mnt/raspberry-rootfs/usr/lib/arm-linux-gnueabihf/libm.a(fesetenv.o): In function `fesetenv': (.text+0x64): undefined reference to `_dl_hwcap' collect2: error: ld returned 1 exit status Makefile:666: recipe for target '../../lib/libQt5Core.so.5.0.2' failed make[2]: *** [../../lib/libQt5Core.so.5.0.2] Error 1 make[2]: Leaving directory '/home/eray/Raspberry/qt-everywhere-opensource-src-5.0.2/qtbase/src/corelib' Makefile:75: recipe for target 'sub-corelib-make_first' failed make[1]: *** [sub-corelib-make_first] Error 2 make[1]: Leaving directory '/home/eray/Raspberry/qt-everywhere-opensource-src-5.0.2/qtbase/src' Makefile:40: recipe for target 'sub-src-make_first' failed make: *** [sub-src-make_first] Error 2 -
@rapid84
I've never worked with rpi but you obviously have some linker error ... for some reason ... are you by chance building statically? If yes, don't, usually static builds are much more harder to handle and satisfy than dynamic libraries. Aside from that, I can't offer much more, just look up the RaspberryPI guide I've linked in my previous post, it looks very good, and maybe someone will pitch in and suggest something else.Kind regards.

I have just done what the instruction is and how i could build it staticly "by chance" ? By the way i have done the instructions that you have given me ( http://exploreembedded.tumblr.com/post/115333857238/guide-to-cross-compile-qt-54-for-the-raspberry-pi) and i got the nearly same error

Hello,how i could build it staticly "by chance" ?
I meant it in its idiomatic meaning: "by any chance - used in enquiring about the possibility of something", not that you're doing that accidentally. :)
i got the nearly same error after "make"
This error I understand, although I have no idea why you get it. The problem is that the linker can't find the libm.so file (the math library). That's why it's giving you tons of undefined references. If I were to hazard a guess, there is some misconfiguration of the library paths and the linker is unable to find the library binary. I hope this helps.
Kind regards.
