Hi All,
Messing about with Dante (the SOCKS5 replacement), I've encountered
some difficulty with run-time linking that I don't understand.
In brief:
$ env LD_PRELOAD=libdsocks.so telnet # works
$ env LD_PRELOAD=libdsocks.so xchat # undefined symbol '_gethostbyname'
$ env LD_PRELOAD=libc.so:libdsocks.so xchat # works
What I don't understand is:
= Why is the run-time linker failing to find _gethostbyname in libc
in the second case? Looking at a ktrace shows that the relative
order of loading libdsocks.so and libc.so is the same for both
telnet and xchat, but the latter `doesn't work'.
I thought LD_BIND_NOW might be useful here, but it isn't.
The same problem is encountered even if the application is linked
(dynamically) with -ldsocks at build time (i.e. undefined symbol
unless I supply LD_PRELOAD=libc.so).
What might I look for in the build of libdsocks.so that would cause
such?
Thanks for any help!
