static

问题 I have build a static library with the Android ndk. I now try to use this library in another Android project //in mainActivity static { System.loadLibrary("MILlib"); } I got the following error when building the test project 02 17:07:24.890 2785-2785/com.MIL.testlib E/AndroidRuntime: FATAL EXCEPTION: main Process: com.MIL.testlib, PID: 2785 java.lang.UnsatisfiedLinkError: dlopen failed: "/data/app/com.MIL.testlib-1/lib/arm/libMILlib.so" has bad ELF magic at java.lang.Runtime.loadLibrary

问题 I use VCPKG to build third party libraries like libcurl for example. I have dynamic and static builds. Obviously, import .lib and object .lib files are contained in two different folders, x64-windows and x64-windows-static respectively. I want to link object libcurl.lib statically with my program, but cannot figure out how to configure Visual Studio to do it. It always ends up using the import lib, rather than object lib and thus my program ends up requiring libcurl.dll at execution. I have

问题 I am working with Java and come through one random problem. Here I had shared sample code of my problem. I want to initialize some of static final date field with my custom string format. public class Sample { protected static final Date MAX_DATE ; static { try { MAX_DATE = new SimpleDateFormat("yyyy-MM-dd").parse("2099-12-31"); } catch (ParseException e) { e.printStackTrace(); } } } While directly putting below line, it's asking for try and catch. protected static final Date MAX_DATE= new

问题 C99 introduced a new function argument notation where the static keyword can be used to specify that the argument has at least N elements. 6.7.6.3 Function declarators, p7 A declaration of a parameter as ''array of type'' shall be adjusted to ''qualified pointer to type'', where the type qualifiers (if any) are those specified within the [ and ] of the array type derivation. If the keyword static also appears within the [ and ] of the array type derivation, then for each call to the function,

问题 Code goes first: void foo(int x) { void bar(int); //is this forward-decl legal? bar(x); } void bar(int x) { //do stuff } In the code above, foo calls bar , usually I put the forward-decl of bar outside of foo , like this: void bar(int); void foo(int x) { bar(); } First, I think it's OK to put bar 's forward-decl inside foo , right? Second, consider this, if bar is a static function like this: static void bar(int x) { //do stuff } Then how should I forward-declare it? I mean should the forward

问题 As of Java 8 you can have default or static methods implemented in Interfaces as the below public interface DbValuesEnumIface<ID, T extends Enum<T>> { T fromId(ID id); ID getId(); static String getDescriptionKey(){ return "this is a test"; } } I would like to declare the above with the static method having a signature that uses bounds defined by the implementing classes since the method's implementation should be the same for all,with the only thing different should be the generics declared,

问题 Let's say I have library (A) implementing the singleton pattern (it has a static variable in its implementation). (A) library is compiled as a static library. Now, let's say I have in my probject: (B) , another static library linking statically with (A) . (C) , another static library linking statically with (A) . (D) , a top level program linking with (B) and (C) . In the end, is my singleton really a singleton (and my variable really static)? Are (B) and (C) seing the same static variable

问题 This code will compile and is well defined under current C standards: static int foo(int); extern int foo(int); The standard specifies that in this situation ( C11: 6.2.2 Linkages of identifiers (p4) ): For an identifier declared with the storage-class specifier extern in a scope in which a prior declaration of that identifier is visible, 31) if the prior declaration specifies internal or external linkage, the linkage of the identifier at the later declaration is the same as the linkage
