Hi Justin, Which problem do you still see __with__ the -p option? Can you provide an example? Cheers, Philippe. PS. Also see Masa's talk at the recent ROOT User's Workshop on the subject of 3rd party libraries. -----Original Message----- From: owner-roottalk@pcroot.cern.ch [mailto:owner-roottalk@pcroot.cern.ch]On Behalf Of Justin Findlay Sent: Thursday, March 11, 2004 3:11 AM To: roottalk@pcroot.cern.ch Subject: [ROOT] preprocessing 3rd party headers with CINT I'd like to use some very useful 3rd party libraries in interactive ROOT, specifically BOOST, but I'm reluctant to try constructing wrappers for including the headers since CINT can't preprocess them properly with or without +P or -p. There ought to be a more elegant solution. #if !defined(__CINT__) #include "your_recalcitrant_header.h[pp]" #else // include forwarding or summary of header that is // needed for parsing the code. #endif running 'g++ -E' on the header (ignoring the errors :) and then feeding the result to ROOT yields a dissapointing "limitation". Limitation: Can't instantiate precompiled template ... Perhaps it is more work than it is worth. Are there any thoughts on how one might go about inserting 3rd party, even templated, libraries into the ROOT command line run time? This would involve surmounting both the header preprocessing and template instantiation difficulties. Here is some previous discussion on simmilar/the same issue[s] if you're interested.
