[Csync2] Re: Building csync2-1.29 on Fedora Core

[Michael Mansour]

Hi Clifford,

Just so you know, I also manually applied the changes in the patch below to
configure.ac file, then ran the autogen.sh to recreate the configure script,
and it still gave the same problem:

# ./autogen.sh
+ aclocal-1.7
+ autoheader
+ automake-1.7 --add-missing --copy
+ autoconf
+ '[' '' = clean ']'

# ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk

checking for rs_sig_file in -lrsync... yes

checking for libgnutls-config... /usr/bin/libgnutls-config
checking for libgnutls - version >= 1.0.0... yes
checking for SSL_new in -lgnutls-openssl... no
configure: error: libgnutls-openssl is required

Note that I'm using SL42 (RHEL4 Update 2) for this.

Thanks and regards,

Michael.
