Follow-ups

--- Mike Frysinger 2008-04-14 05:10:53

i'll take this

--- Mike Frysinger 2008-04-14 05:22:46

there was a typo in configure.in where it wouldnt save CPPFLAGS at the right

place and then later restore an unset var thus clobbering the CPPFLAGS value

--- Mingquan Pan 2008-04-15 00:22:11

Yes,the smb can fork now.

Unfortunately, the can't open file issue still remaining.

Now, the running log is:

root:/> smbmount //10.100.4.174/users /mnt rw -o

username=test,password=test

params.c:OpenConfFile() - Unable to open configuration file

"/etc/config/smb.conf":

No such file or directory

Can't load /etc/config/smb.conf - run testparm to debug it

root:/> cp /bin/version /mnt/test

Since it is shown in the above bug report, I would prefer continue with it

rather than file a new bug,unless you protest...:)

--- Mike Frysinger 2008-04-15 00:35:06

that's a warning, not an error ... are you saying the mount doesnt work for you

--- Mingquan Pan 2008-04-15 02:14:45

It can mount,and it can also find the config file now after your change in

Makefile.Close,
