osx - CUDA toolkit error on MAC: unable to open output file 'vectorAdd.o':, Permission denied -

-

i trying run cuda toolkit on mac, when compiling cuda sample programs error:

unable open output file 'vectoradd.o': 'error opening output file 'vectoradd.o': permission denied'

i checked environmental variables , driver installation , seems ok.

do have clue problem?

thanks!

if copy whole samples folder , contents home directory, should able compile samples there without sudo.

the problem directories contain sample files owned root , not writable admin users, compiler cannot create new output files , folders needs if running admin user.

if want compile samples in situ (as installation guide seems suggest), can compile them using sudo. alternatively can change ownership of samples directory , subdirectories recursively:

sudo chown -r your-user-name /developer/nvidia/cuda-7.0/samples

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
