Although the RPM packaging system is not a supported option for xmlsectool, it is possible to build an RPM using a script and patch file contributed by Peter Schober.
This procedure has been tested on CentOS 7 only.
This procedure does not work as described with the 2.0.0-beta-1 release due to file naming issues. For the beta 1 release, modify the procedure by unpacking the distribution release into an xmlsectool-2.0.0-beta-1 directory, renaming that directory to xmlsectool-2.0.0, and using the zip command to make a new xmlsectool-2.0.0-bin.zip distribution in the SOURCES directory. It is also necessary to use the xmlsectool.spec and xmlsectool.patch files from the git repository rather than the ones from the beta 1 distribution.
To build the RPM, first install the rpm-build package on your CentOS system.
The rest of the procedure can (and should) be performed as a normal, non-privileged user.
Create a file ~/.rpmmacros along the following lines:
%_topdir /home/iay/rpm %packager Ian Young <ian@iay.org.uk>
Create the build environment inside your user directory as follows:
$ mkdir -p ~/rpm/{BUILD,RPMS/noarch,SOURCES,SPECS}
In the SPECS directory, place a copy of the xmlsectool.spec file found in the doc directory of the distribution.
In the SOURCES directory, place a copy of the distribution .zip file, and a copy of the xmlsectool.patch file found in the doc directory of the distribution.
Now build the RPM:
$ cd ~/rpm/SPECS $ rpmbuild -bb xmlsectool.spec
The RPM file can now be found in the ~/rpm/RPMS/noarch directory.
