SVO : Fast - Coner Detector - Installation: Plain CMake (No ROS) - c++

Question

I'm working on a project of drone and I'm having an issue with my Raspberry Pi 2 B. When I'm trying to install Fast - Corner Detector I get this on screen
pi#raspberrypi ~/workspace/fast/build $ make

I have Cmake installed (sudo apt-get cmake), Gcc (4.6.3) and OpenCV.
How can I solve the problem?

Answer 1

Raspberry Pi is ARM, -msse* does it apply. Based on the CMakeFile, they detect ARM and disabled SSE flags. Maybe it is not working for you, perhaps due to a different cmake version
Try changing this
IF(DEFINED ENV{ARM_ARCHITECTURE})
to
IF(DEFINED $ENV{ARM_ARCHITECTURE})
This is line 34 in CMakeLists.txt
If the fix does not work, then you could manually enable ARM specified flags by editing CMakeLists.txt
Remove this:
IF(DEFINED ENV{ARM_ARCHITECTURE})
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mfpu=neon -march=armv7-a")
ELSE()
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mmmx -msse -msse -msse2 -msse3 -mssse3")
ENDIF()
and replace with this
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mfpu=neon -march=armv7-a")
Maybe report an issue on github and tell the authors about it.
EDIT: you want to do these edits in https://github.com/uzh-rpg/fast/blob/master/CMakeLists.txt
Also try setting export ARM_ARCHITECTURE=1 before compiling
