After I compile mrpt manually, I have a trouble with build mrpt files -


i'm trying combine every system ros before wanted check whether works or not run file on clion, , got these errors.

when first compiled it, fine, later had issues mrpt header files, deleted them , compiled manually, , problem happened. can advice?

you have mix of different mrpt versions installed in system.

i don't recommend doing sudo make install unless have strong reason it; compiling project in own build directory generate mrptconfig.cmake file, allows cmake find mrpt ros or whatever other user project.

if cmake doesn't find automatically, set environment variable export mrpt_dir=/home/xxx/path/to/mrpt/build , work.

your problem right cleaning mess may under /usr/local/. take @ directory , if project have make installed mrpt, recommend deleting sudo rm -fr /usr/local/*.

if have other projects there... well... must run sudo make uninstall mrpt build dir, manually make sure there no remaining files.

the link error against opencv looks cmake configured project 1 opencv version, 1 got installed (perhaps via ros packages?). after doing clean of /usr/local mentioned above, delete current mrpt cmake build directory , start scratch again.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
