RE: [Wrapper-user] Re: HP-UX libwrapper.so fails to load

[Andreas W. <And...@ei...>]

Eric,

since you didn't provide the error messages you get when running the =
wrapper, it's hard to tell what your problem is.
I'm also not quite sure if you mentioned it, but what are the versions =
of your OS and GCC?

BTW, you should link the executable and the library with the same linker =
and not one with gcc and one with ld.

Cheers,
Andreas
