makefile - Make doesn't finish when run with entr -

i'm trying use entr recompile change c file following command: $ echo ex8.c | entr make ex8 && ./ex8 when run cc output nothing happends $ echo ex8.c | entr make ex8 && ./ex8 cc -wall -g ex8.c -o ex8 if write manually works great $ make ex8 && ./ex8 how should write entr work? the man page wasn't quite detailed enough, installed , tried it. note command 3 distinct shell commands: echo ex8.c , entr make ex8 , , ./ex8 . these connected pipe (the first two) , && operator (the final two). 2 commands in pipeline both started in parallel. final command not invoked until pipeline completes, if exit code success run. this means final command ./ex8 not started until after entr make ex8 command finishes. but, entr not exit after runs make 1 time: entire point continue watch source file , run make every time changes. that's why final command never invoked: entr never exits. there multiple ways fix simplest

i use randomforest model predict class memberships. 'x' consists of 10 classes use train 'training_predictors' values extracted large rasterstack/brick. specific line of codes is: r_tree<-randomforest(x ~. , data=training_predictors, ...) then run 'predict' using model 'r_tree' apply rasterstack 'predictor_data', follow: predictions<-predict(predictor_data, r_tree, filename=outraster, fun=predict na.rm=true, format="pcdisk", overwrite=true, progress="text", type="response"). the output raster use thematic map. i use conditional inference trees mode 'cforest' instead of randomforest achieve same goals. i understand 'predict' can used cforest, yet, have not been able generate raster files, such randomforest illustrated above. it should run fine, may need add argument oob=true, , identify factors if there any. example data p <- matrix(c(48, 48, 48, 53, 50, 46

Removing multiple elements from a vector c++ -

-
here code checks if 2 units killed after attack each other, pass in position in vector when remove 1 vector changed in size , therefore 2nd unit out of range. how can remove both simultaneously? if ((myhealth <= 0) && (enemyhealth <= 0)) { playerunits.erase(playerunits.begin() + myunit, playerunits.begin() + enemyunit); } else if (myhealth <= 0) { playerunits.erase(playerunits.begin() + myunit); } else if (enemyhealth <= 0) { playerunits.erase(playerunits.begin() + enemyunit); } first point: in first block, call erase(x, y) different expect - erases whole range of elements starting @ index x until before index y. example, if have vector [a,b,c,d,e,f,g], erase(2,5) erase indexes 2,3,4, end [a,b,f,g]. i'm guessing want erase 2 elements, not entire range. second point: dieter lücking pointed out, erase higher index element first, this: if (myunit > enemyunit) { playerunits.erase(playerunits.begin() + myunit); playerunits.
