Compilation 1. How to compile XMLSec? As most UNIX libraries XMLSec follows the "standard": gunzip -c xmlsec-xxx.tar.gz | tar xvf - cd xmlsec-xxxx ./configure --help to see the options, then the compilation/installation proper ./configure [possible options] make make install Probably you may have to rerun ldconfig or similar utility to update your list of installed shared libs. At this point you can check that the library is compiled successfully by running make check 2.What other libraries are needed to compile/install XMLSec? XMLSec requires following libraries: LibXML2 (http://xmlsoft.org): a very powerfull XML parsing and manipulating library LibXSLT (http://xmlsoft.org/XSLT/): a nice XSLT processor based on LibXML2 OpenSSL (http://www.openssl.org): well known cryptographic library If you are running a Linux system then there is a good chance that you already have all libraries installed. Also XMLSec requires the normal C ANSI API (please report any violation to this rule you may find). Aleksey Sanin $Id$
