Hello' I've found the server to install syslog-ng and i downloaded the stable version with the 0.3.8 version of the libol librairie. I found a document on the web which explain HowTo install it ... therefore i tried, but i got some problem during installation. First i've installed the libol libs (0.3.8) with the ./configure, make, make install - and it seems to be all right. Then, i tried the same sequence with syslogNG and i' got an error concerning libol, as following : [root@XXX-Linux syslog-ng-1.6.8]# ./configure checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes ... ... checking libol version >= 0.3.16... no configure: error: Required libol version not found, make sure that your libol version is in the 0.3.x branch [root@XXX-Linux syslog-ng-1.6.8]# Where as libol seems to be great installed : [root@XXX-Linux download]# libol-config --version 0.3.8 I saw a paper about this problem ( https://lists.balabit.hu/pipermail/syslog-ng/2004-April/006023.html ) but the answer is not goood for me cause' it tells that it is a version problem (like 0.3.9 is too old, and older than the 0.3.13 ... i cannot understand this :-/) so i'm quite Lost ... can anyone help please ? *********************************** Ce message et toutes les pieces jointes (ci-apres le "message") sont confidentiels et etablis a l'intention exclusive de ses destinataires.
