Description Mario Sergio Fujikawa Ferreira freebsd_committer freebsd_triage 2010-02-27 00:40:03 UTC 
- Add compile gcc option to make sure that boost compilation toolchain
  acknowledges that gcc versions prior to 4.3.x do not implement
  inclass member initialization

	- This enables net-p2p/libtorrent-rasterbar-14 to build
	  python bindings with the base system gcc on FreeBSD 8.x.
	  Without resorting to gcc 4.3, gcc 4.4 or gcc 4.5 ports.

	- Prior to this patch, libtorrent-rasterbar-14 python
	  bindings could only be built with gcc 4.3+. This is a
	  problem for 2 reasons:
		1) We required gcc 4.3+ to be available and/or built
		   prior to building rasterbar.
		2) Any port requiring rasterbar will also have to
		   depend upon gcc 4.3+

	- This patch should be merged to the original boost
	  distribution.

- Bump PORTREVISION to acknowledge the fix

- files/patch-boost__config__compiler__gcc.hpp

This patch is breaking parts of boost, at least lexical_cast, probably also other type_trait related constructs.

Defining BOOST_NO_INCLASS_MEMBER_INITIALIZATION to fix a problem in Boost.Python (and specifically for the p2p port in question) is just too much, since in class member initialization should be available in gcc since version 3 at least. I would suggest to develop a patch for net-p2p/libtorrent-rasterbar-14 instead of breaking boost ;)

Simple test program:
#include <iostream>
#include <boost/lexical_cast.hpp>

using namespace boost;

int main(int, char** argv)
{
  std::cout << boost::lexical_cast<bool>(std::string(argv[1])) << std::endl;
}

See the boost website for details on the issue:

https://svn.boost.org/trac/boost/ticket/4669

and

https://svn.boost.org/trac/boost/ticket/4381

Thanks
Michael
