Description Rich Mattes 2011-11-26 14:15:44 EST
Description of problem:
There seems to be an issue in the lexical_cast.hpp header that's preventing my package (ompl) from building.

Version-Release number of selected component (if applicable):
boost-devel  1.48.0-1.fc17

How reproducible:
Attempt to build the master branch of the ompl package.

Additional info:

#include <boost/lexical_cast.hpp>

struct ble;
typedef struct ble *meh;

int main(int argc, char *argv[])
  meh heh;
  return boost::lexical_cast<std::string>(heh);

Proposed fix

To decide whether source type is char, they first ask for whether it's char or wchar, and then compare sizeofs.  I think the same can be achieved by simply asking whether src is char, but I might be missing something.  This patch implements what I propose.  I'll pass it through upstream now.
Comment 3 Petr Machata 2011-11-28 19:53:19 EST
https://svn.boost.org/trac/boost/ticket/6182 is the upstream ticket.
Comment 4 Petr Machata 2011-11-29 10:22:13 EST
I built a package that should fix this issue.  Could you please try whether it actually does?
Comment 5 Rich Mattes 2011-11-29 19:45:16 EST
Looks like your update has taken care of the issue, I was able to build ompl against it.  Thanks for looking at this, I'll go ahead and close this ticket as fixed.
