running error!

[lqniunjunlper]

When i run the quick_start, i have the following error:
paddle_trainer: error while loading shared libraries: libgflags.so.2: cannot open shared object file: No such file or directory
But i have installed gflags.2.2.0, which includes the following libs:
/usr/local/lib/libgflags.so /usr/local/lib/libgflags.so.2.2.0 /usr/local/lib/libgflags_nothreads.so.2.2
/usr/local/lib/libgflags.so.2.2 /usr/local/lib/libgflags_nothreads.so /usr/local/lib/libgflags_nothreads.so.2.2.0

why paddle use libgflags.so.2 instead of libgflags2.2.0???

Besides, when i installed gflags2.0, which includes libgflags.so.2, but i also have another running error:
paddle: line 46: 1877 Illegal instruction ${DEBUGGER} $MYDIR/../opt/paddle/bin/paddle_trainer ${@:2}

why?

libgflags.so.2 is a symbolic link of libgflags.so.2.2.0.
The reason for paddle use libgflags.so.2 instead of libgflags2.2.0, is libgflags2.1.0 is also ok.
You can add a symbolic link of libgflags, like this: ln -s libgflags.so.2.1.0 libgflags.so.2

Thanks @hedaoyuan
I reinstall gflags using gflags-2.1.2 ( [https://github.com/gflags/gflags/releases] ) and these exists libgflags.so,2.
But when i run quick_start demo, i have the another error like this:
/paddle: line 46: 14445 Illegal instruction ${DEBUGGER} $MYDIR/../opt/paddle/bin/paddle_trainer ${@:2}

Make sure your cpu support avx instructions. Otherwise you need to compile PaddlePaddle with WITh_AVX turning off for cmake

Thanks @emailweixu . The reason is my CPU do not support avx instructions, after turning WITH_AVX OFF, paddle run successfully.
