I have some problem in building my own openldap client sources.

[이지훈 <jhlee@plantynet.com>]

At first i apoligize for my poor english. i'm not an English guy.

 

I wrote two source files with policy.c and common.c

 

What the built application do just is bind to my own ldap server.

 

When i make the source files, I got the following warnings not errors.

 

fortunately the target application , 'policy' was made successfully.

 

anyway Why the errors happened ?

 

[root@wisep source]# make
cc -g -O2 -o policy policy.o common.o ldsversion.o  -L/usr/local/BerkeleyDB.4.2/lib liblutil.a libldif.a libldap.a liblber.a /usr/local/lib/libsasl2.so -lssl -lcrypto -lresolv -ldl -Wl,--rpath -Wl,/usr/local/lib -Wl,--rpath -Wl,/usr/local/lib
