Explicitly exporting shared library functions in Linux
提问by theactiveactor
Is there a Linux equivalent of __declspec(dllexport)notation for explicitly exporting a function from a shared library? For some reason with the toolchain I'm using, functions that aren't class members don't appear in the resulting shared library file.
是否有 Linux 等价的__declspec(dllexport)符号用于从共享库中显式导出函数？由于我使用的工具链的某种原因，不是类成员的函数不会出现在生成的共享库文件中。

__attribute__((visibility("default")))
And there is no equivalent of __declspec(dllimport)to my knowledge.
并且没有__declspec(dllimport)与我的知识相当的东西。
#if defined(_MSC_VER)
// Microsoft
#define EXPORT __declspec(dllexport)
#define IMPORT __declspec(dllimport)
#elif defined(__GNUC__)
// GCC
#define EXPORT __attribute__((visibility("default")))
#define IMPORT
#else
// do nothing and hope for the best?
#define EXPORT
#define IMPORT
#pragma warning Unknown dynamic link import/export semantics.
#endif
