i try to replace libglib-2.0.so :

ln -sf $PWD/lib/aarch64-linux-gnu/libglib-2.0.so.0.4800.2 $PWD/usr/lib/aarch64-linux-gnu/libglib-2.0.so

but still failed.

all libs and headers is sync from the em-linux.

and configure by this:

./configure -shared -c++std c++14 \
 -opensource -release --confirm-license -pkg-config -shared \
 -device linux-jetson-tx1-g++ \
 -device-option CROSS_COMPILE=/home/linger/crossbuild/gcc-linaro-5.5.0-2017.10-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu- \
 -sysroot /home/linger/crossbuild \
 -nomake examples -nomake tests \
 -prefix /home/linger/crossbuild/JetsonTX2/qt5 \
 -extprefix /home/linger/crossbuild/JetsonTX2/qt5 \
 -hostprefix /home/linger/crossbuild/JetsonTX2/qt5-host \
 -opengl es2 \
 -pch

this result looks fine and no warning and error output.

I cannot find the right version of libglib-2.0.a , just use -no-glib to disable it.

re-building now everything looks fine...
