Linux distro:
Fedora 17 x86_64

Syslog-ng source tarball:
syslog-ng-3.3.5.90-20120810-v3.3.5-43-g19f6c.tar.gz


we have encountered a couple of problems when running syslog-ng-3.3.5.90-20120810 under Fedora 17 x86_64:

 1) ld.so library path
 2) undefined symbol: tls_context_setup_session


Steps to reproduce the problem:

 1) just run "/usr/sbin/syslog-ng --version"

----------


The library path problem can be solved by creating the file "/etc/ld.so.conf.d/syslog-ng.conf" containing
the syslog-ng module directory ( /usr/lib64/syslog-ng in this particular case ).

Running syslog-ng under strace without touching the ld.so library paths produces:
----------
# # strace -e trace=file /usr/sbin/syslog-ng --version
...
access("//usr/lib64/syslog-ng/libafsocket.so", F_OK) = 0
stat("//usr/lib64/syslog-ng/libafsocket.so", {st_mode=S_IFREG|0755, st_size=103560, ...}) = 0
open("//usr/lib64/syslog-ng/libafsocket.so", O_RDONLY|O_CLOEXEC) = 4
open("/lib64/tls/libsyslog-ng-crypto.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/lib64/libsyslog-ng-crypto.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/usr/lib64/tls/x86_64/libsyslog-ng-crypto.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
stat("/usr/lib64/tls/x86_64", 0x7fff0f81fcb0) = -1 ENOENT (No such file or directory)
open("/usr/lib64/tls/libsyslog-ng-crypto.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
stat("/usr/lib64/tls", {st_mode=S_IFDIR|0555, st_size=4096, ...}) = 0
open("/usr/lib64/x86_64/libsyslog-ng-crypto.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
stat("/usr/lib64/x86_64", 0x7fff0f81fcb0) = -1 ENOENT (No such file or directory)
open("/usr/lib64/libsyslog-ng-crypto.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
stat("/usr/lib64", {st_mode=S_IFDIR|0555, st_size=49152, ...}) = 0
Error opening plugin module; module='afsocket', error='libsyslog-ng-crypto.so: cannot open shared object file: No such file or directory'
...
-----------

Note that all syslog-ng modules with the exception of libsyslog-ng-crypto.so are loaded
from the syslog-ng modules directory.
