matlab - error while loading shared libraries: libboost_system-mt-1_49.so.1.49.0 -

-

i'm beginner matlab , c++ user , trying run code provided me. code

the error is: 

/path/folder: error while loading      shared libraries: libboost_system-mt-1_49.so.1.49.0: cannot open shared object    file: no such file or directory

the folder exists , file it's trying call in there. don't understand error saying libboost library?

if need provide of code calls folder, let me know. not sure how info provide.

i assume have solved problem. see might still useful put hints here see many posts asking similar questions without being answered.

the solution add library path system environment variables. unfortunately not set outside matlab (i mean edit .bashrc in ubuntu etc.).

the correct way use matlab's functions of reading , setting environment variables: getenv() , setenv().

suppose library file located at: /home/username/lib/, need write in matlab scripts:

setenv('ld_library_path',[getenv('ld_library_path') ';/home/username/lib']);

i using linux, however, think solve problem in other oss.

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
