Linux opencv independent installation : not found in CMake -


i creating object tracking program rely on opencv. want able test different versions of opencv have linking errors.

i installed last version of opencv (a69b435c928f422fb5f99c02cf2dcae57dcf820a) in following folder : /usr/local/opencv/opencv-trunk instead of usual /usr/local.

then followed official tutorial use opencv cmake in linux, had following "normal" error :

cmake error @ cmakelists.txt:11 (find_package):   not providing "findopencv.cmake" in cmake_module_path project has asked cmake find package configuration file provided "opencv", cmake did not find one.    not find package configuration file provided "opencv" of following names:      opencvconfig.cmake     opencv-config.cmake    add installation prefix of "opencv" cmake_prefix_path or set "opencv_dir" directory containing 1 of above files.  if "opencv" provides separate development package or sdk, sure has been installed.   -- configuring incomplete, errors occurred!

so did suggested , added following line in cmakelists.txt :

# find independently installed opencv libraries set(opencv_dir "/usr/local/opencv/opencv-trunk/share/opencv")

this complete cmakelists.txt file :

# find independently installed opencv libraries set(opencv_dir "/usr/local/opencv/opencv-trunk/share/opencv")  cmake_minimum_required(version 2.8) project( displayimage ) add_executable( displayimage displayimage.cpp )  find_package( opencv required ) include_directories( ${opencv_include_dirs} ) target_link_libraries( displayimage ${opencv_libs} )

now have following error , don't find how deal it.

cmake error @ cmakelists.txt:12 (find_package):   found package configuration file:      /usr/local/opencv/opencv-trunk/share/opencv/opencvconfig.cmake    set opencv_found false package "opencv" considered not found.  -- configuring incomplete, errors occurred!

if have faced issue in such context solutions welcomed ;)

if running intellij or other ide, try re-building cmake cache (or remove build directory , run cmake utility again).

i believe not best practice - set configuration variable opencv_dir hard-coded in cmakelists.txt. try setting manually, environment variable cmake utility:

opencv_dir=/usr/local/cellar/opencv3/3.1.0_2/share/opencv/ cmake ..

or set ide make you:

cmake environmental variables in intellij/clion

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
