[Exim] Exim 4.10 Compile error with LDAP !

Hi ,

I have some problem compiling Exim 4.10 with LOOKUP_LDAP support .
I have installed openldap-2.0.25 successfully and /usr/include/ldap.h is available also .
When I try to make the exim this error happened when want to compile ldap.c :

make[2]: Entering directory `/usr/src/exim-4.10/build-Linux-i386/lookups'
gcc -c -O cdb.c
gcc -c -O dbmdb.c
gcc -c -O dnsdb.c
gcc -c -O dsearch.c
gcc -c -O ldap.c
ldap.c: In function `perform_ldap_search':
ldap.c:530: dereferencing pointer to incomplete type
ldap.c:531: dereferencing pointer to incomplete type
make[2]: *** [ldap.o] Error 1
make[2]: Leaving directory `/usr/src/exim-4.10/build-Linux-i386/lookups'

So what is the problem ?!
Any suggestion ?
