error "relocation R_AARCH64_ADR_PREL_PG_HI21 against external symbol `__stack_chk_guard@@GLIBC_2.17'" in QT5.8.0 source building with Cross compiler aarch64
-
hi,
I compile QT5.8.0 source with Cross compiler aarch64:
Linux: Ubuntu 14.04
Cross compiler: gcc-linaro-6.2.1-2016.11-x86_64_aarch64-linux-gnu
QT: 5.8.0
configure:
./configure
-v
-opensource
-confirm-license
-device-option CROSS_COMPILE=/home/suma/GUI/gcc/gcc-linaro/bin/aarch64-linux-gnu-
-device linux-jetson-tx1-g++
-prefix /usr/local/qt5

-hostprefix /home/suma/GUI/qt/qt5-host
-nomake examples

make :
when create libQt5Core.so.5.8.0 (qt-everywhere-opensource-src-5.8.0/qtbase/src/corelib),
I encounter a error like below:

Any Ideas?

changing the path order of the linked libraries can fix my issue!
error path:
QMAKE_LIBDIR +=
$$[QT_SYSROOT]/usr/lib
$$[QT_SYSROOT]/lib/aarch64-linux-gnu
$$[QT_SYSROOT]/usr/lib/aarch64-linux-gnu
rigth path :
QMAKE_LIBDIR +=
$$[QT_SYSROOT]/usr/lib/aarch64-linux-gnu
$$[QT_SYSROOT]/usr/lib
$$[QT_SYSROOT]/lib/aarch64-linux-gnu
Note :
/usr/lib/_ (1)
/usr/lib (2)
