I reproduced this problem through the image you provided，
The root cause of the problem is like this：
1. you enabled --with-glog when you run config_brpc.sh, so glog will be
linked, and the script only found a dynamic library(libglog.so), so glog will
be dynamic linked. Similarly, gflag will be linked in a static way
2. gflag is referenced by glog, and libglog.so linked gflags in dynamic
way, it is reasonable.
3. in some platform, libgflags.a is complied without option '-fPIC', and
it is the default behavior when compiling gflags, so when you link
./example/echo_c++/echo_server with **libgflags.a and libglog.so**, error
occured.
In some other platform , even if they are compiling static libraries,
they will add options '-fPIC', for example Ubuntu. to solve this promble,
compile gflags with source code, and set **CPPFLAGS=-fPIC**, then everything
works fine.
