Hi Thorsten,
re: std::string SGPAth::realpath() const
That's strange no one has done this for WIN32 ;=()
Do NOT know about the MAC, but WIN32 has always,
ALWAYS had, in <stdlib.h> -
char *_fullpath( char *absPath, const
char *relPath, size_t maxlength );
So that gives something very similar to realpath()...
#if defined(_WIN32)
// with absPath NULL, will allocate, and ignore length
char *buf = _fullpath( NULL, path.c_str(), _MAX_PATH );
if (!buf) {
SG_LOG(... as per unix ...);
return path; // failed, return path as is
}
std::string p(buf);
free(buf); // was allocated using malloc(), so
return p;
#elsif defined(_APPLE_) && (MAC_OS_X_VERSION_MAX_ALLOWED <= 1050)
return path;
#else
// current unix code
...
#endif
And although I do not have a lot of experience with
Cygwin I understand it knows how to convert a DOS/
Windows path to its unix kludge, /c/..., so do not
need to do anything special... but maybe...
But this is all aside from the possible 'bug'
Jon is pointing out...
HTH,
Regards,
Geoff.
