+If you want to enable regular expression matching, you need the PCRE package. +For most Linux systems, it is already installed. In that case add the locations +of the PCRE header and library to your RELEASE file: +
++PCRE_INCLUDE=/usr/include/pcre +PCRE_LIB=/usr/lib ++
+If you want to build StreamDevice for platforms without PCRE support, +it is the easiest to build PCRE as an EPICS application. +Download the PCRE package from www.pcre.org +and compile it with my EPICS compatible +Makefile. +Then define the location of the application in your RELEASE file. +
++PCRE=/home/epics/pcre ++
+Regular expressions are optional. If you don't want them, you don't need this. +
