java - Can't find /lib/libJOCL-linux-x86.so -

-

i have nvida graphic card , use serious computations. downloaded driver nvida webside , installed jocl bindings. downloaded 1 of demo programs , compiled it. program not run because:

> error while loading native library > "jocl-linux-x86" base name "jocl" > operating system name: linux > architecture : i386 architecture bit > size: 32 stack trace attempt > load library resource: > java.lang.nullpointerexception: no > resource found name > '/lib/libjocl-linux-x86.so' @ > org.jocl.libutils.loadlibraryresource(libutils.jav > a:139) @ > org.jocl.libutils.loadlibrary(libutils.java:83) > @ org.jocl.cl.<clinit>(cl.java:47) @ > joclsample.main(joclsample.java:50) > stack trace attempt load > library file: > java.lang.unsatisfiedlinkerror: no > jocl-linux-x86 in java.library.path @ > java.lang.classloader.loadlibrary(classloader.java > :1681) @ > java.lang.runtime.loadlibrary0(runtime.java:840) > @ > java.lang.system.loadlibrary(system.java:1047) > @ > org.jocl.libutils.loadlibrary(libutils.java:93) > @ org.jocl.cl.<clinit>(cl.java:47) @ > joclsample.main(joclsample.java:50) > exception in thread "main" > java.lang.unsatisfiedlinkerror: > not load native library @ > org.jocl.libutils.loadlibrary(libutils.java:117) > @ org.jocl.cl.<clinit>(cl.java:47) @ > joclsample.main(joclsample.java:50)

trying solve did following:

  • i positive "jocl-0.1.4d.jar" file added classpath; /lib/libjocl-linux-x86_64.so sure inside jar

  • i extracted libjocl-linux-x86_64.so form jar , used respective -djava.library.path= command.

  • the libjocl-linux-x86_64.so library on ld_library_path

  • i run ldconfig in proper directory index library

but problem persists

according error message you're running in 32 bit vm, mean you'd need 32bit .so file (or switch using 64bit jvm).

note java loads .so files java.library.path (and not ld_library_path).

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
