java - Call graph generation using Spark (Soot -Eclipse framework) - memory issues -


i'm trying generate call graph using spark (in soot -eclipse framework) java code. started helloworld. small example looks system memory isn't enough.

soot has run out of memory allocated java vm. allocate more memory soot, use -xmx switch java. example (for 400mb): java -xmx400m soot.main .

my machine windows based 4gb core i-5. eclipse process running javaw.exe. out-of-memory behavior expected helloworld using soot? i'm new running profiling java , im not sure if library classes adding huge overhead.

or maybe right question - how use -xmx switch running soot more memory in eclipse on windows -anyone done this?

the command in eclipse below. im using simplification options in spark analysis. 

soot.main     --w --d c:\users\nbalaji\workspace\helloworld\sootoutput  --process-path c:\users\nbalaji\workspace/helloworld/src;     --cp /c:/users/nbalaji/workspace/helloworld/bin/, < bunch of java/jre7 files >

edit: resolved now. soot survival guide: when setting run configuration should add following parameters jvm -xmx512m -xss256m increase vm memory.

soot using memory not bug. hello-world program transitively calls thousands of methods, of analyzed.

as exception message suggests, should use:

java -xmx400m soot.main ...

this jvm option, not soot option.

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
