java - Android NDK UnsatisfiedLinkError Native method not found -

-

unsatisfiedlinkerror while running android ndk app. have read the android dev jni tips on error. , far can tell doing correctly. have studied jni spec, doesn't seem help. need jni_onload method? optional. need kind of header soundtouch-jni.cpp file? don't think so.

basics: package io.hpp.soundtouch , class soundtouch , java call native method string getversionstring() , c++ method extern "c" jstring java_io_hpp_soundtouch_soundtouch_getversionstring(jnienv *env, jobject thiz)

error log:

this copy of soundtouch-jni.cpp file using:

#include <jni.h> #include <android/log.h>  #include "include/soundtouch.h"  //#define logv(...)   __android_log_print((int)android_log_info, "soundtouch", __va_args__) //#define logv(...)   //#define dll_public __attribute__ ((visibility ("default")))  using namespace soundtouch;  extern "c" jstring java_io_hpp_soundtouch_soundtouch_getversionstring(jnienv *env, jobject thiz) {     const char *verstr;      //logv("jni call soundtouch.getversionstring");      // call example soundtouch routine     verstr = soundtouch::getversionstring();      // return version string     return env->newstringutf(verstr); }

this copy of soundtouch.java file

package io.hpp.soundtouch;  public final class soundtouch {     // native interface function returns soundtouch version string.     // invokes native c++ routine defined in "soundtouch-jni.cpp".     public native final string getversionstring();      // load native library upon startup     static     {         system.loadlibrary("soundtouch");     }   }

i figured out. well, not really. restarted eclipse , worked. woot woot!

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
