Here is the offending code:
/* get the name of the user */
uid = getuid();
#ifdef HAVE_GETPWUID
pwdent = getpwuid(uid);
#else
pwdent = NULL;
#endif
if (NULL != pwdent) {
user = strdup(pwdent->pw_name);
} else {
orte_show_help("help-orte-runtime.txt",
"orte:session:dir:nopwname", true);
return ORTE_ERR_OUT_OF_RESOURCE;
}
Is it possible on this platform that you don't have getpwuid? I'm surprised at
the code as we could just use the uid instead - not sure why this more
stringent test was applied
