Stripping linux shared libraries

Question

We\'ve recently been asked to ship a Linux version of one of our libraries, previously we\'ve developed under Linux and shipped for Windows where deploying libraries is gene

Answer 1

If you wrap up your private part in an anonymous namespace then neither std::abs nor private_function can be seen in the symbol table:

namespace{
#include
  float private_function(float f)
  {
    return std::abs(f);
  }
}
extern "C" float public_function(float f)
{
        return private_function(f);
}

compiling (g++ 4.3.3):

g++ -shared -o libtest.so test.cpp -s

inspecting:

# nm -DC libtest.so
         w _Jv_RegisterClasses
0000200c A __bss_start
         w __cxa_finalize
         w __gmon_start__
0000200c A _edata
00002014 A _end
000004a8 T _fini
000002f4 T _init
00000445 T public_function
