安装openldap时，我遇到错误并且编译停止，请提供建议。
Portfolio我已将bdb配置如下：
cc -g -I../../../include -I../../../include -I.. -I./.. -I./../../../libraries/liblmdb -I/sites/bdb/include -c ./../../../libraries/liblmdb/mdb.c -o mdb.o
"./../../../libraries/liblmdb/mdb.c", line 4625: warning: implicit function declaration: pthread_mutexattr_setrobust

安装openldap：
cd /sites/db-4.8.30/build_unix/
../dist/configure --prefix=/sites/bdb
make
make install
我在最后一步遇到了错误。
以下是env
cd openldap-2.4.44/
./configure --prefix=/sites/openldap --enable-dynamic --enable-spasswd --enable-slapd --enable-mdb --enable-monitor
make depend
make all
