Building:

On a (CC7) build machine prerequisite packages need to be installed:

yum install -y python-devel libcap-devel rpm-build python-six python-setuptools

Note: python 3.4 equivalent is:

yum install -y python34-devel libcap-devel rpm-build python34-six python34-setuptools

building hltd library RPM:

scripts/libhltdrpm.sh

building hltd executable RPM:

scripts/hltdrpm.sh

optionally to only read parameters from cache:

scripts/hltdrpm.sh --batch # or -b

fffmeta RPM is now merged with hltd RPM and should no longer be built or installed.

Note: Provide as last command line parameter the param cache file containing last values used. If it does not exist, the file will be created. "scripts/paramcache.template" is available with default values (note that you need to provide correct password). If no name is provided to the script, default name will be "paramcache". "env":"vm" parameter value is now obsolete with "prod" covering all use cases.
