hidden Indicates that the affected external linkage entities have the hidden visibility attribute. These entities are not exported in shared libraries, but their addresses can be referenced indirectly through pointers. internal Indicates that the affected external linkage entities have the internal visibility...
但libsubfunc.a是第三方库,我们不能去改它的代码,也不能改它的头文件,对于这种情况,gcc提供了下面方式来支持: #pragma GCC visibility push(hidden) #include "subfunc.h" #pragma GCC visibility pop int funcA(int a, int b) { return subfunc(a, b); } 这种方式更方便灵活。 参考文档 GCC Visibil...
extern void foo(int); #pragma GCC visibility push(hidden) extern void someprivatefunct(int); #pragma GCC visibility pop You should really only use this for legacy code. All new code should specify each declaration as exported or local individually. ...

The effect of this is that GCC may, effectively, mark inline methods with "__attribute__ ((visibility ("hidden")))" so that they do not appear in the export table of a DSO and do not require a PLT indirection when used within the DSO. Enabling this option can have a dramatic ...
