c++ - Copy exe file to Qt build directory -


i trying write qt application use qprocess call ffmpeg.exe convert media files. cannot figure out best way make sure ffmpeg.exe file gets copied development directory build directory built (and later deployed) application have access it.

i have seen information using installs parameter in .pro file (https://stackoverflow.com/a/13168287) qmake docs say:

note qmake skip files executable.

with of above said, how should 1 go making sure exe file want use qprocess ends in build directory (ready deployed later)?

you can use qmake_post_link execute copy command when application built. put in .pro file :

win32:{      file_pathes += "\"$$pwd/path/to/files/ffmpeg.exe\""      config(release, debug|release):{         destination_pathes += $$out_pwd/release/         destination_pathes += path/to/deploy/directory     }     else:config(debug, debug|release):{         destination_pathes += $$out_pwd/debug/     }      for(file_path,file_pathes){         file_path ~= s,/,\\,g         for(dest_path,destination_pathes){             dest_path ~= s,/,\\,g             qmake_post_link += $$quote(xcopy $${file_path} $${dest_path} /i /y $$escape_expand(\n\t))          }     } }

you should add paths files want copied file_pathes variable , paths destination directories destination_pathes variable. files copied destinations when application built.

here ffmpeg.exe gets copied application build , deploy directories in release mode , build directory in debug mode.

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
