#     RPM spec file for ParaView-3.12.0

# Description
#     RPM spec file for creating a relocatable RPM

#     Martin Beaudoin, Hydro-Quebec, (2010)

#------------------------------------------------------------------------------

# We grab the value of WM_THIRD_PARTY and WM_OPTIONS from the environment variable
%{expand:%%define _WM_THIRD_PARTY_DIR %(echo $WM_THIRD_PARTY_DIR)}
%{expand:%%define _WM_OPTIONS         %(echo $WM_OPTIONS)}

# Disable the generation of debuginfo packages
%define debug_package %{nil}

# The topdir needs to point to the $WM_THIRD_PARTY/rpmbuild directory
%define _topdir	 	%{_WM_THIRD_PARTY_DIR}/rpmBuild
%define _tmppath	%{_topdir}/tmp

# Will install the package directly $WM_THIRD_PARTY_DIR
#   Some comments about package relocation:
#   By using this prefix for the Prefix:  parameter in thi file, you will make this 
#   package relocatable. 
#
#   This is fine, as long as your software is itself relocatable.
#
#   Simply take note that libraries built with libtool are not relocatable because the
#   prefix we specify will be hard-coded in the library .la files.
#   Ref: http://sourceware.org/autobook/autobook/autobook_80.html
#
#   In that case, if you ever change the value of the $WM_THIRD_PARTY_DIR, you will
#   not be able to reutilize this RPM, even though it is relocatable. You will need to 
#   regenerate the RPM.
