Library not found - Githubissues

ARUNSOORAJPS commented 7 years ago

'libSubsense' is not found inside the python folder. Should I do anything to create the library file?

File "C:/Users/ics02517.AD001/Documents/Python Scripts/Object Tracking/subsense-master/Python/Subsense.py", line 28, in init self.lib_subsense = np.ctypeslib.load_library(LIB_NAME, LIB_PATH)

File "C:\Anaconda\lib\site-packages\numpy\ctypeslib.py", line 128, in load_library raise OSError("no file with expected extension")

OSError: no file with expected extension

I have a same problem here... What should I do? I tried to cmake in the subsense root directory but libSunsesce doesn't created.

I had a lot of problems too... Finally It compiled in this way:

1. Add the find_package command in My CmakeList.txt _basically I only added a findpackage instruction, you can delete some lines there if you want.

SET(PROJECT_NAME Subsense) PROJECT(${PROJECT_NAME}) CMAKE_MINIMUM_REQUIRED (VERSION 2.8.3)

find_package( OpenCV REQUIRED )

set(EXTRA_INC_DIRS /usr/local/include )

LIST(APPEND LINK_LIBS opencv_core opencv_video opencv_features2d opencv_imgproc )

set(SS_DIR ${CMAKE_CURRENT_SOURCE_DIR})

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

if(APPLE) set(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE) set(CMAKE_INSTALL_NAME_DIR ${CMAKE_INSTALL_PREFIX}/lib) set(CMAKE_MACOSX_RPATH ON) set(CMAKE_SKIP_BUILD_RPATH FALSE) set(CMAKE_BUILD_WITH_INSTALL_RPATH FALSE) set(CMAKE_INSTALL_RPATH "${CMAKE_INSTALL_PREFIX}/lib") set(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE) endif()

file(GLOB LIB_SRC_FILES ${SS_DIR}/Subsense/*.cpp) include_directories(${SS_DIR} ${EXTRA_INC_DIRS})

add_library(Subsense SHARED ${LIB_SRC_FILES}) target_link_libraries(Subsense ${LINK_LIBS})

2. Comment the lines 39-41 in the BackgroundSubtractorLBSP.cpp file as follows: //cv::AlgorithmInfo* BackgroundSubtractorLBSP::info() const { //return nullptr; //}

3. Comment the line 29 in BackgroundSubtractorLBSP.h file: //virtual cv::AlgorithmInfo* info() const;

**4. Locate the compiled libSubsense.so file together with the python script. That's all.
