Re: Using Linux Emulation libraries

["David Dudley" <DavidDu%cctexas.com@localhost>]

You're right, the message is 'Shared Object "libnss_dns.so.2" not
found'.  Problem is, none of the libraries used by the software
reference this library, so I'm trying to figure out how it gets
referenced.  A number of other programs use the libraries also, and none
of them try to reference this, but the program in question is being
imported using the definitions for Linux and Solaris, so I'm wondering
if something different is being done for them.

If you really did manage to get it compiled as a NetBSD binary then it

shouldn't be looking for that library at all.  Is the the exact message

you get when you run it, or do you get something like "Shared object 
"libnss_dns.so.2" not found" ?
If the latter, then the build process did something to explicitly link

against that library and it shouldn't have.  You probably just need to

remove a -l option from the link command.
If the former, then I'm guessing your program is trying to dlopen the 
library for some reason, in which case you'll need to find that in the

code and change it.

   No, if you're recompiling it under NetBSD, the whole emulation 
framework is not needed.  You only need that when you're running Linux

_binaries_.
