So instead of doing all this here, you should call the detail::appdath_path() function defined in <boost/compute/detail/path.hpp>. I recently extracted this code from the program class so you may have to rebase on top of the develop branch to get it.


// Path to appdata folder.
#ifdef WIN32
static const std::string appdata = detail::getenv("APPDATA")
+ delim + "boost_compute";
#else
static const std::string appdata = detail::getenv("HOME")
+ delim + ".boost_compute";
#endif
try
{
if(boost::filesystem::exists(appdata))

I don't think you need both an existence check and a try/catch block. I'd lean towards just using the if(exists(appdata)) condition and then removing the try/catch.

{
boost::filesystem::remove_all(appdata);
}
}
catch(boost::filesystem::filesystem_error const & err)
{
std::cout<<err.what()<<std::endl;
}
#endif
