Hi @wexi
The build is passing. If your application depends on previous version of librealsense, please configure it to track the legacy branch instead of master.

[wexi]

It's my first build attempt and it is failing. Here is how:

CMakeFiles/realsense2.dir/build.make:326: recipe for target 'CMakeFiles/realsense2.dir/src/error-handling.cpp.o' failed
make[2]: *** [CMakeFiles/realsense2.dir/src/error-handling.cpp.o] Error 1
make[2]: *** Waiting for unfinished jobs....
CMakeFiles/Makefile2:99: recipe for target 'CMakeFiles/realsense2.dir/all' failed
make[1]: *** [CMakeFiles/realsense2.dir/all] Error 2
Makefile:129: recipe for target 'all' failed
make: *** [all] Error 2

Line 326 of the a/m makefile is:
@$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --green --progress-dir=/home/enoch/librealsense/build/CMakeFiles --progress-num=$(CMAKE_PROGRESS_12) "Building CXX object CMakeFiles/realsense2.dir/src/error-handling.cpp.o"
/usr/bin/c++ $(CXX_DEFINES) $(CXX_INCLUDES) $(CXX_FLAGS) -o CMakeFiles/realsense2.dir/src/error-handling.cpp.o -c /home/enoch/librealsense/src/error-handling.cpp

This error-handling.cpp is not missing. How can I turn on debug logging of the build process?

Hi @wexi

The librealsense2 (tag: 2.8.0) build should be fine. My build machine is Ubuntu 16.04 + kernel 4.4.0.97. Please check below instructions to see if you see the same issue:
https://github.com/IntelRealSense/librealsense/blob/v2.8.0/doc/installation.md

Hi, Unfortunately going back to "2.8.0" did not help, same build error and same error going forward with the "development" branch:

CMakeFiles/realsense2.dir/build.make:326: recipe for target 'CMakeFiles/realsense2.dir/src/error-handling.cpp.o' failed
make[2]: *** [CMakeFiles/realsense2.dir/src/error-handling.cpp.o] Error 1

I am not experienced with cmake. Is there a standard way to tell it to build a Makefile with a more meaningful debug output?

Hi@ wexi,
What is the command line params you use to invoke cmake and make, and what are the outputs.
Please provide the full log of the two

master branch now builds fine. Thanks.
