But simple solution with adding third argument to static library case doesn't work. Comment in rte_compat.h file describes steps needed to add new version of the function and it says: * 2) rename the existing function int foo(char *string) to * int __vsym foo_v20(char *string) * * 3) Add this macro immediately below the function * VERSION_SYMBOL(foo, _v20, 2.0); * * 4) Implement a new version of foo. * char foo(int value, int otherval) { ...} * * 5) Mark the newest version as the default version * BIND_DEFAULT_SYMBOL(foo, 2.1); So probably BIND_DEFAULT_SYMBOL macro for shared library case needs to be modified to have two arguments. I'm not familiar with that symver syntax so I need some help. It would be better when original author say how it should look like. Best Regards Maciek
