Hi,
while looking into making hpx install into lib64/, I came across
hpx::util::find_prefixes(), which contains a loop I don't understand:
That's the code:
std::string prefixes = find_prefix(library);
typedef boost::tokenizer<boost::char_separator<char> > tokenizer;
boost::char_separator<char> sep(HPX_INI_PATH_DELIMITER);
tokenizer tokens(prefixes, sep);
std::string result;
for(tokenizer::iterator it = tokens.begin(); it != tokens.end(); ++it)
{
...
find_prefix(), according to the code and to the documentation, returns "the
installation path of the specified module", i.e. 1 path.
Why is there the need to tokenize that using a PATH_DELIMITER (":" here) and
then iterate over all tokens ? It looks to me like there is always exactly one
path ?
Related, later on in that loop, the subdirs "/bin" and "/lib" are hardcoded.
Could that be changed to use the result from dll.get_directory() directly
instead of trying to reconstruct it ?
Alex
