vsftpd compilation warnings with "VSF_BUILD_TCPWRAPPERS" defined

[Paolo De Bernardini]

Hi.

I've encountered 19 warnings compiling vsftpd on HP-UX [B.11.23 U ia64] with "VSF_BUILD_TCPWRAPPERS" defined.
The compilation ends correctly but vsftpd doesn't start.

Does anyone have any suggestion?

Thanks,
Paolo

I'm not sure what this script does ./vsf_findlibs.sh.

But t_errno is in libxti.so and libnsl_s.so.1.
t_alloc(3) mentioned two headers, probably depending on differrent standards. Unfortunately it doesn't mention which shlib to use.

Obviously X/OPEN Transport Interface - XTI matches libxti. ;-)

Your problem with the rfc931_timeout unsat is due to a broken libwrap.so. See:
