Hi,
  In a program that i am developing, i am linking with a third party software. Now when i call a function asctime in my program i get a core dump. When i debug the core i found that there was a call to a function __eprintf and this functions type was "hpux export stub". What is this hp ux export stub? This is the case when i am linking with the shared library. However when i am linking with the static library i am not getting any core dump and the program is working fine. Now when i did nm on the libraries(shared and static) for asctime functions i found the following thing:

In shared library:
asctime             |          |undef |code   |
asctime             |   1398712|uext  |stub   |

In static library:
asctime             |          |undef |code   |


Now you can see the differnece between the libraries as far the function asctime is concerned.
Do you have any clue why i am not getting core dump in calling asctime using static library, and i am getting a core dump when i use the shared library.

Thanks,

-Prabhakar.

How is your program linked together. Try using immediate binding ( ld option).

Thsi way you see at startup time if some functions are missings in the shared libraries.

If it works with static libraries, it's also possible that the order in which the shared libraries are specified is not correct.

Which version of HPUX are u using?
