story,it may be a little long :)<br /> I mistook the parameter -W of initdb at the first time and used it like
this:<br/> initdb -U pgsql -W 12345 -D /home/pgsql/pg_data<br /> And I found the database was not created in the
rightdirectory, but I could not find a log file to find out why.<br /> So, I debug initdb and found out I have mistook
theparameter -W, I should use it like this:<br /> initdb -U pgsql -W -D /home/pgsql/pg_data<br /> <br />
however,when I debug initdb.c, VAR optind was supported to increased after getopt_long pasered every parameter,<br />
butit was alway equal to 1.<br /> <br /> And there is a segment of initdb.c.<br /> if (optind < argc)<br />
{<br /> do something statement<br /> } <br /> <br /> I print the value of optind and argc:<div
class="im"><br/> (gdb) p optind<br /> $11 = 1<br /> (gdb) p argc<br /> $12 = 6<br /> <br /></div> optind
isobvious less than argc, but the statement above do not excute at all.<br /> <br /> QUESTION:<br /> 1.why does
thestatement above not excute?<br /> 2.why is optind always equal to 1? <br clear="all" /><br />-- <br />Clover
