Cant compile realsense viewer/tools

[RTasa]

I was able to build the examples and see the camera functions.

I went to build the tools and this is the error I received.

/usr/bin/x86_64-linux-gnu-ld: CMakeFiles/realsense-viewer.dir/realsense-viewer.cpp.o: undefined reference to symbol 'pthread_create@@GLIBC_2.2.5'

//lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line

Answering my own question.

A file named CMakeLists.txt

contains line

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

and it needs to be

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread")

Adding the pthread option fixes the error.
