Thanks for the bug report. Just some questions:

• What operating system are you using (if Linux, what distro)?
• Can you attach the output of cmake / make when you built the server? This might give some useful information.
• Does the segfault still happen if you run the example as described here?

@srajotte I have added you since you'll probably have a better idea of this than I do. Would it help if we had the core dump file? (Not that I dabble in such things...)

Thanks for your reply
first I run the build_linux.sh in FaceWarperServer, and I got this:

It seems pass the build, and When I cd builddictionary , I found there nothing named FaceWarperServer, so I run the make command, finally I got this:

Scanning dependencies of target FaceWarperServer
[ 33%] Building CXX object CMakeFiles/FaceWarperServer.dir/source/FaceWarper.cpp.o
[ 66%] Building CXX object CMakeFiles/FaceWarperServer.dir/source/shader.cpp.o
[100%] Linking CXX executable FaceWarperServer
[100%] Built target FaceWarperServer

Looks make successfully also.
But when I run ' python run_facewarp.py --results_dir=frontalized_faces '
I still got the problem:

/media/liuzongxuan/disk2/workspace/github/DepthNets/FaceWarper/FaceWarperServer/build/FaceWarperServer
Segmentation fault (core dumped)
