Hi,

I am compiling lftp 4.4.5 on CentOS 5.6

openssl and openssl-devel are both installed.

I ran ./configure --prefix=/usr/local --with-openssl=/usr/lib which seemed fine,

but when I run make I get the following error:

/bin/sh ../libtool --silent --tag=CXX --mode=compile gcc
-DHAVE_CONFIG_H -I. -I../lib -I../lib -I../trio -I/usr/lib/include
-O2 -Wall -Wwrite-strings -Woverloaded-virtual -fno-exceptions
-fno-rtti -fno-implement-inlines -MT lftp_ssl.lo -MD -MP -MF
.deps/lftp_ssl.Tpo -c -o lftp_ssl.lo lftp_ssl.cc
lftp_ssl.cc: In constructor 'lftp_ssl_openssl::lftp_ssl_openssl(int,
lftp_ssl_base::handshake_mode_t, const char*)':
lftp_ssl.cc:835: error: 'SSL_set_tlsext_host_name' was not declared in
this scope
make[1]: *** [lftp_ssl.lo] Error 1
make[1]: Leaving directory `/root/build/install/lftp-4.4.5/src'
make: *** [all-recursive] Error 1

What can I do to fix this problem and install lftp with ssl?

TIA

Nuffi

Maybe you have an old version of ssl? SSL_set_tlsext_host_name was
introduced in 1.0.0a [01 Jun 2010].

Hi Nuffi,

It looks like your OpenSSL version does not support SNI (which was
added in lftp 4.4.4).
What is the version installed on CentOS 5.6? SNI was added to OpenSSL >= 0.9.8.

Some suggestions to solve this:
1) upgrade SSL library to >= 0.9.8
2) or, locally compile an OpenSSL >= 0.9.8 and link against it using
--with-openssl
3) or, use lftp 4.4.3 (before SNI was added)
