__declspec(dllimport) 120363-__declspec(dllimport) static library

In the case of data, using __declspec(dllimport) is a convenience item that removes a layer of indirection When you import data from a DLL, you still have to go through the import address table Before __declspec(dllimport), this meant you had to remember to do an extra level of indirection when accessing data exported from the DLL__declspec(dllimport)지시자를 사용함으로서 1번의 형태로 DLL에 제공되는 함수를 호출하는 것을 알 수 있다 상기 코드에서 컴파일러는 __declspec(dllimport) 지시자를 보았을 경우에 실제 함수인 "MyFunc"을 참조하지 않고 "__imp__MyFunc"을 참조하는 코드를 만들어 놓는다 · Your code is trying to link to an external dll, look for "__declspec (dllimport)" in your code to see where To do this this you need the header from the dll and the dll The fact that you are getting this message indicates that you have the header, but cannot find the dll referenced

 · hello there are questins here,please help me In windows We use "DLL" with __declspec(dllimport) , I want to use "so" in Linux,how__declspec(dllimport)声明一个导入函数，是说这个函数是从别的DLL导入。我要用。一般用于使用某个dll的exe中 不使用 __declspec(dllimport) 也能正确编译代码，但使用 __declspec(dllimport) 使编译器可以生成更好的代码。 · __declspec (dllexport) int next(int n) { return n 1;

Using __declspec (dllimport) is optional on function declarations, but the compiler produces more efficient code if you use this keyword However, you must use __declspec (dllimport) for the importing executable to access the DLL's public data symbols and objects__declspec(dllimport) means that the symbol will be imported from a DLL It is used when compiling the code that uses the DLL Because the same header file is usually used both when compiling the DLL itself as well as the client code that will use the DLL, it is customary to define a macro that resolves to __declspec(dllexport) when compiling the DLL and __declspec(dllimport__declspec(dllimport) là bộ định danh lớp lưu trữ cho trình biên dịch biết rằng một hàm hoặc đối tượng hoặc kiểu dữ liệu được định nghĩa trong một DLL bên ngoài Hàm hoặc đối tượng hoặc kiểu dữ liệu được xuất từ một DLL với __declspec(dllexport) tương ứng

 · This is a tough one, because the problem could be one of a few things The function given is a function exported from a DLL Either as a static class member or from a namespaceDllImport and dllexport enable interop with DLL files We can use a C DLL dynamic link library, or a custom legacy DLL—even one we can't rewrite but have the ability to modify Settings extern "C" { __declspec(dllexport) void __cdecl SimulateGameDLL (int a, int b); · __declspec(dllimport) is not strictly necessary for functions, but it helps the compiler generate more efficient code If I recall correctly, __declspec(dllimport) is in fact necessary in order to use imported data

A __declspec attribute placed after the class or struct keyword applies to the userdefined type For example class __declspec(dllimport) X {};This is a Microsoft specific extension to the C language which allows you to attribute a type or function with storage class information The canonical examples are __declspec (dllimport) and __declspec (dllexport), which instruct the linker to import and export (respectively) a · Hey @nickgillian the example you link to above contains an error, testAccuracy is undefined But in any case, I can also reproduce the unresolved external symbol issue Steps to reproduce Create a static build or GRT using the cmake

Annotating calls by using the __declspec(dllimport) can make them faster __declspec(dllimport) は、エクスポートされた DLL データにアクセスするために常に必要です。 __declspec(dllimport) is always required to access exported DLL data DLL から関数をインポートする21 __declspec (dllexport)用于导出符号，也就是定义该函数的dll；__declspec (dllimport)用于导入，也就是使用该函数。 因为这个头文件既要被定义该函数的dll包含，也要被使用该函数的程序包含，当被前者包含时我们希望使用 __declspec (dllexport) 定义函数，当被后者包含时我们希望使用 dllimportIn this case, the attribute applies to X The general guideline for using the __declspec attribute for simple declarations is as follows declspecifierseq initdeclaratorlist;

__declspec(dllimport) 声明一个导入函数，是说这个函数是从别的DLL导入。我要用。一般用于使用某个dll的exe中 不使用 __declspec(dllimport) 也能正确编译代码，但使用 __declspec(dllimport) 使编译器可以生成更好的代码。} Insead of using namespace and class, you should simply use extern "C" statement like the one shown below__declspec(dllimport) MSDN中说明： 不使用 __declspec(dllimport) 也能正确编译代码，但使用 __declspec(dllimport) 使编译器可以生成更好的代码。 编译器之所以能够生成更好的代码，是因为它可以确定函数是否存在于 DLL 中，这使得编译器可以生成跳过间接寻址级别的代码，而这些代码通常会出现在跨 DLL 边界的函数调用

Raymond March 21st, 14 A customer was having trouble exporting a function with the __decl­spec(dll­export) declaration specified, but found that if the function was in a static library, no function was exportedI have searched and only found information specific to the fortran compiler I have also found one mention in a forum that said "get rid of it" That won't work for a file I need to make transportable between Windows and Linux systems · WINBASEAPI is a macro that expands to __declspec(dllimport) or nothing (and, presumably, to __declspec(dllexport) in the configuration used to actually build Windows from sources), while WINAPI expands to __stdcall One goes before the return type, the other after
